dotnet test coverage

If you’d like to, read more about ReportGenerator on the project’s GitHub. For the purpose of this article, you'll create a class library that will be the system under test, and two corresponding unit test projects. There is an alternative to the Basic scenario of performing coverage analysis in .NET Core projects. You don’t have to use Xunit for this, but it’s the testing framework I like, and it isn’t always as well documented for this kind of thing so it is the tool I’m using. If you write more code and do not write a unit test then code coverage will be decreased; if you write a unit test then code coverage will be increased. First, we’ll need to have a piece of code that represents logic which should be submitted to unit testing. I found just installing Visual Studio 2017 with all the .Net SDKs quite simple for that. And Test Explorer gives you a visual explorer panel when you can run tests: all of them, a group in context or individual test. The –collect parameter instructs dotnet test to create code coverage files with Coverlet. Configure test task. If you’d like to, read more about Coverlet on the project’s GitHub. To add ReportGenerator as a tool, you will need to manually add this code to your test project file: Before you go on, do a quick check of the version number, you likely want the latest version number if you have no reason to use a lower one. Moreover your project can also has many (or not) tests. If you only care about running code coverage for a single project, you probably want to go the “per-project tool” route (adding the nuget package / CLI Tool Reference). In common practice, automated unit tests are what exercise the program so that the code coverage tool can perform its measurements. To do this, go to the “Arguments” field of the dotnet test build step and append --collect "Code Coverage", as well as ensuring that “Publish test results and code coverage” is enabled. Coverlet is a cross platform code coverage library for.NET Core, with support for line, branch and method coverage. This allows for System.Math to be accessible without a using System; namespace declaration. I blogged about .NET Core, SonarQube and Code Coverage - but this felt like a hack. As part of the dotnet test run, a resulting coverage.cobertura.xml file is output to the TestResults directory. Just run dotnet test and pass the parameter /p:CollectCoverage=true to enable the output. To add the nuget package to your project run the following command - dotnet add package coverlet.msbuild from the cosole and you should be all set. Coverlet is a code coverage framework for .NET, with support for line, branch and method coverage. Make sure you know to what extent your code is covered with unit tests. Now in Rider! Microsoft.CodeCoverage package brings infra for collecting code coverage from vstest.console.exe and "dotnet test". Once the build is green, I am able to see code coverage tab but it still does not show html report. Run dotnet test command to generate a coverage report. Global Tools are essentially cross-platform console tools that you can create and distribute with .NET Core & Nuget. The action requires a line to pass in the GITHUB_TOKEN, which is available in … Line 21: install the report generator tool for coverage reports; Line 24: run "dotnet test" to invoke the test. I mentioned Coverlet at the start of this article, you’re probably wondering what it is? Likewise if you think you may want to run code coverage on a build server, you probably want to go with the packages installed via your .csproj file. (Alexey Totin) […] Poor at english says: ... All our dotNet tools (dotCover, dotTrace, and dotMemory) use a common profiling core that was initially developed only for Windows. From the command prompt, create a new solution to encapsulate the class library and the two test projects. Getting code coverage reports on the command line for .NET Core has been a gap, and unless you are using Visual Studio Test or a 3rd party pay for … They are meant for devs - this isn't a replacement for chocolatey or apt-get - this is more like npm's global developer tools. When that was done, it then changed directories, stepping up one level. Below is the example coverage.cobertura.xml file. Here’s a sample of what that command looks like: This command is generating coverage metrics based on the “SampleApi.dll”. Cobertura is popular code coverage utility in Java world. JetBrains dotCover is a.NET unit test runner and code coverage tool that integrates with Visual Studio and JetBrains Rider. Why? To do this, go to the “Arguments” field of the dotnet test build step and append --collect "Code Coverage", as well as ensuring that “Publish test results and code coverage” is enabled. The concept of “.NET Core Global Tools” was introduced in .NET Core 2.1 as a feature of the .NET Core CLI. Open this file to explore the coverage results in your web browser. Let’s imagine that you have VSTS build pipeline for continuously build and test you project. The dotnet test command launches the test runner console application specified for a project. With coverage data I also output unit test results in Microsoft and xUnit formats to UnitTests folder. Now that the test project has ReportGenerator installed, we’re ready to actually make something useful from the code coverage metrics we’ve collected. The test task only generates .coverage files for each test project. Using them outside of the project won’t work because the command cannot be found - you may have seen this with ReportGenerator if you tried to run it from outside the Test project’s directory. Coverlet collects Cobertura coverage test run data, which is used for report generation. Your own computer, AppVeyor, Azure DevOps and i'm assuming GitHub Actions. However, let it be enough to say that the unit test… I want to measure the Code Coverage of my XUnit-Tests in an ASP.NET Core application. Warnings Plug-into scan for com… Getting started. This is a pretty high level overview of some of the options you can supply to Coverlet, if you want to get more details on what is possible, check out the Coverlet documentation. This is a cross platform option that relies on the .NET Core CLI, and it is great for build systems where MSBuild is not available. Find the current & past versions of ReportGenerator here. open source project on GitHub - ReportGenerator. After running this command, an HTML file represents the generated report. get familiar the CLI .net commands. In this blog post I’ve shown you a few different ways to run code coverage and report generation. Let's generate a cool UI using ReportGenerator. For example, we want to get coverage of tests in some project. For manual test sessions, dotCover shows what parts of code were called during the session and which parts were not reached. A program with high test coverage, measured as a percentage, has had more of its source code executed during testing which suggests it has a lower … To get started, we need a test project and some NuGet packages. All in all, dotnet dotсover test is the fastest and easiest way to analyze tests coverage from the command line. It is worth mentioning the that Numbers class library was intentionally added to the System namespace. Also it expects the existence of Azure DevOps build pipeline that is connected to source code repository. Details here. Adda reference to web application project and write some unit testsif you start with a new test project. For example, for at least 80% total coverage of the lines of code, these threshold parameters must be added (to the local command or Azure DevOps arguments).dotnet test /p:CollectCoverage=true /p:threshold=80 /p:thresholdType=line /p:thresholdStat=total Code coverage tools measure how completely a program runs as it is running.The trick is to run the software while the code coverage tool is monitoring the program. There’s a separate command for getting coverage in .NET Core projects: cover-dotnet or just dotnet. So if you’re interested in the code coverage of your project, but don’t want to commit to the package, this isn’t a bad way to go. The first way I’ll show to generate code coverage metrics is to add Coverlet to your test project. This name is required but is case insensitive. As an example, if you have a simple application with only two conditional branches of code (branch a, and branch b), a unit test that verifies conditional branch a will report branch code coverage of 50%. This allows us to filter out code that we don’t want included in code coverage metrics. Test data is transformed to Cobertura format by Coverlet – a cross platform code coverage library for .NET Core. Use dotnet.exe to run coverage analysis of .NET Core unit tests. If you look at the coverage.json file it likely won’t make any sense, don’t worry we’ll do something with it in a bit. There is a newer prerelease version … If there is any difficult-to-test code, for example, network, database, unit test, class, or method etc. First get dotnet test to output a trx file with the test results by passing the arguments -l trx. Added coverlet, ... Coverage Gutters that can read in lcov files and others and highlight line gutters with red, yellow, green to show test coverage. Well done! (Alexey Totin) […] Poor at english says: ... All our dotNet tools (dotCover, dotTrace, and dotMemory) use a common profiling core that was initially developed only for Windows. With Azure DevOps you need to do this step yourself, meaning that apart from generating the test results with the unit tests step (dotnet test) you need to generate the code coverage report (HTML) manually in … Post summary: Examples how to measure code coverage of .NET Core unit tests with OpenCover. Add this package dependency by running the dotnet add package command: The previous command changed directories effectively scoping to the MSBuild test project, then added the NuGet package. One last parameter that comes in handy is /p:Exclude. Microsoft.NET.Test.Sdk 4. Coverage Gutter display coverage result with colors in your screen and you can activate or deactivate it. The reports generated can show total coverage from a project, file, and namespace level, and also allow you to drill into the source code and visualize which lines have been covered. Rename the UnitTest1.cs files to PrimeServiceTests.cs. Execute the Coverage.bat file. This post is a kind of recipe to get started into .NET Core 3.1 with coverage and SonarQube to keep track of metrics. code coverage can work on any build system which has dotnet core SDK installed. Install Nuget packages. If you look at the coverage.json file it likely won’t make any sense, don’t worry we’ll do something with it in a bit. Line 21: install the report generator tool for coverage reports; Line 24: run "dotnet test" to invoke the test. This is a cross platform option that relies on the .NET Core CLI, and it is great for build systems where MSBuild is not available. Unit Testing Framework Then follow it up with the Publish Test Results task. ReportGenerator can then take those XML outputs as an input and generate you a single XML code coverage result for the entire project. OpenCover is the process that wraps around the actual dotnet test runner and collects coverage analysis. OpenCover is the process that wraps around the actual dotnet test runner and collects coverage analysis. Code Coverage in .NET Core is tricky if you want to use it in a CI build and/or SonarQube. 10:18:32.251 INFO – Unit Test Coverage Sensor is started 10:18:32.253 INFO – Integration Test Coverage Sensor is started 10:18:32.253 INFO – 12/12 source files have been analyzed 10:18:32.253 INFO – Overall Coverage Sensor is started 10:18:32.253 INFO – Sensor JavaScript Squid Sensor (done) | time=1804ms Unfortunately, in this case, you won’t get an aggregated summary of tests results, instead, you will get a summary per test project. I will use two different Global Tools to produce some code coverage reports similar to how we did earlier in the post. The other two parameters specify the target directory for the results to be stored, and the report type format - HTML. Add the projects to the root of the solution. It supports multiple coverage formats, like json (default),Icov, opencover, cobertura. just use attribute From the command prompt, change directories to the XUnit.Coverlet.MSBuild project, and run the dotnet test command: The resulting coverage.cobertura.xml file is output. And Test Explorer gives you a visual explorer panel when you can run tests: all of them, a group in context or individual test. For this post I’ll assume you’re already familiar with unit testing and XUnit, if you’re not read up on that first and come back to this post when you’re ready to find some test coverage metrics. Also, when trying to improve coverage, one may want to keep generating the report after every test written. To do this, you must choose your criteria and minimum threshold. > dotnet test /p:CollectCoverage=true Add Coverlet to the test projects. If you will want to run code coverage on your local dev across many projects you may want to install the global tools. If there is any difficult-to-test code, for example, network, database, unit test, class, or method etc. ReportGenerator converts coverage reports generated by Cobertura among many others, into human readable reports in various formats. While this article focuses on C# and xUnit as the test framework, both MSTest and NUnit would also work. Then lines 25–29 publish the report to coveralls.io using the Coveralls GitHub Action. The first step was to get the ‘dotnet test’ build step to collect the code coverage, and not just dump TRX files. You can do it directly with the general Microsoft driver: dotnet.exe. Line 02 shuts down any remaining background build services, just in case any keep a lock on the .sonarqube directory. Using the dotnet sln command: This will create a new solution file name XUnit.Coverage in the UnitTestingCodeCoverage directory. Post summary: Examples how to measure code coverage of .NET Core unit tests with OpenCover. the glob pattern "+(testProjectOne|testProjectTwo)" or "**/*Tests.csproj" should add both of the test projects. This is so that the test projects have access to the PrimeService for testing. Additional arguments that are added to the dotnet test … If you’re like me you probably were left with questions like how to I specify where to store the output, how to I generate the metrics in another format, and so on. Thus, we need to install the coverlet.msbuild package in order to generate coverage reports in the CI pipeline. Examples below are based on GitHub SampleDotNetCore2RestStub repository. Those are integration tests because they test more than one application module at a time, but they are run with a unit testing … Filtering can be applied by namespace, assembly, and more in this manner /p:Exclude=[Assembly-Filter]Type-Filter. The previous example showed you how to quickly get some metrics from your tests. ReportGenerator is another tool I briefly mentioned, it generates easy-to-read coverage reports in various formats. Build the solution using the dotnet build command: If the build is successful, you've created the three projects, appropriately referenced projects and packages, and updated the source code correctly. There are two types of code coverage tools: In this section, the focus is on data collector tools. Rename the Class1.cs file to PrimeService.cs. My requirements were: Runs on Linux and WindowsDisplays a… Below is the example coverage.cobertura.xml file.  •  This page lists analysis parameters related to test coverage and execution reports. SonarQube doesn't run your tests or generate reports. Added coverlet, which integrates with MSBuild and automatically runs when you "dotnet test" if you "dotnet test /p:CollectCoverage=true" (I think this should command line switch should be more like --coverage" but there may be an MSBuild limitation here.) If you’re interested in other tools that are available here’s a good list of some Global Tools. This post is about Measuring code coverage of .NET Core applications with Visual Studio. The batch file performs the below operations: Those lcov files look like this, showing file names, file numbers, coverage, and number of exceptions. TonyRanieri.com, "-reports:TestResults\coverage.cobertura.xml", 'c:\source\test-coverage-sample-code\src\SampleApi.Test\TestResults\coverage.cobertura.xml', "-reports:coverage-reports\coverage.cobertura.xml", read more about Coverlet on the project’s GitHub, read more about ReportGenerator on the project’s GitHub, Find the current & past versions of ReportGenerator here. After you’ve installed the ReportGenerator Global Tool, you can run it using this command: Be sure that all of the command is on one line or it may not work correctly - don’t try to break it up into multiple lines, wrapping is fine. It's unfortunately still Windows-only, but they have removed the requirement for Visual Studio Enterprise. With SonarCloud you only need to publish test results and it will do the reporting for you. One word of warning, DO NOT use dotnet add package... to install ReportGenerator, this will not allow it to work as a tool on the CLI. I hope now it is clear what code coverage is and how to control it. Configure test task. Let’s take a look how we can do this using out-of-box solution in VSTS. You may want to change the version number being used, but other than that you can save your project file and then run a dotnet restore to finish setting up the ReportGenerator tool. The xunit, xunit.runner.visualstudio and Microsoft.NET.Tests.Sdk packages are required for xUnit, while the dotnet-xunit CLI tool allows us to run tests directly with dotnet xunit and supply xUnit parameters instead of going through dotnet test. Test data is transformed to the Cobertura format by Coverlet — a cross platform code coverage library for .NET Core. dotnet test got an additional parameter: --collect:"XPlat Code Coverage" Coverlet is a tool which gives you the option to create code coverage files in multiple formats and isn’t dependent on the OS. The test task added above only generates .coverage files for each test project. If you’re curious my example project uses v2.6.3. . This blog post shows how to generate code coverage reports for .NET and ASP.NET Core applications on Azure DevOps. Tony Ranieri If you’re interested in a way to set up your local system so that you don’t need to worry about installing more dependencies or where you’re at in the file system in relation to the test project, read on to find out how to set up Coverlet and ReportGenerator as Global Tools. This article is based on the sample source code project, available on samples browser. dotnet-testx is a dotnet tool that handles the following for you: dotnet-test-explorer.autoWatch. after that, we can use easily the integration between MSBuild and coverlet to run the test and measure the coverage with the following command: dotnet test /p:CollectCoverage=true. Coverlet also integrates with the build system to run code coverage after tests. The output from running Coverlet as a Global Tool is more or less the same as the per-project tool’s output, so I’ll skip including it here. Once this conversion is done, I am using reportgenerator to use this xml and generate report in a coverageresult folder. Now in Rider! Code coverage is a measurement of the amount of code that is run by unit tests - either lines, branches, or methods. If true, starts dotnet watch test after test discovery is completed. This is the tricky part. The test runner executes the tests defined for a unit test framework (for example, MSTest, NUnit, or xUnit) and reports the success or failure of each test. To install the ReportGenerator NuGet package as a .NET global tool, use the dotnet tool install command: Run the tool and provide the desired options, given the output coverage.cobertura.xml file from the previous test run. Using the coverage analysis data, you can easily get to the source code of the tested application. You can follow msbuild integration guide here. When you run the command you’ll see something like this: In the command above we’re specifying to use the cobertura format with the /p:CoverletOutputFormat=cobertura parameter, and the /p:CoverletOutput="./TestResults/ tells dotnet test & Coverlet to store the resulting metrics in a folder called “TestResults”. Read on and I’ll explain how and provide link a sample project at the end of this post. That means we can just "dotnet test" and it'll build and run tests. Essentially, you need to ensure that the test projects are run under dotnet test with a different output XML file to the same folder. Create two new xUnit Test Project (.NET Core) templates from the same command prompt using the dotnet new xunit command: Both of the newly created xUnit test projects need to add a project reference of the Numbers class library. Also, we need to add –collect:”Code Coverage” to add a logger for code coverage as shown: Convert Code Coverage Files. dotnet add package coverlet.msbuild And because it integrates directly with dotnet test there is no other work to do. Overall it looks pretty similar to what we were doing before, except now we supply the path to the SampleApi.dll. We also need some NuGet packages to make things work: 1. coverlet.msbuild 2. It is available at the official dot.net siteand installs the dotnet CLI tool and registers it globally for all users on the PATH variable. I love working with .NET Core on the command line (CLI) and Visual Studio Code. From the command prompt, use the dotnet add command: The MSBuild project is named appropriately, as it will depend on the coverlet.msbuild NuGet package. To enable code coverage, you need to run the dotnet test command with CollectCoverage property with value true. They are meant for devs - this isn't a replacement for chocolatey or apt-get - this is more like npm's global developer tools. Luckily dotnet CLI have another command for running tests – namely dotnet vstest.In this case, we do not operate on projects but we provide a location for assemblies with tests. Convert Code Coverage Files. just use attribute "[ExcludeFromCodeCoverage]" either class or method level. Copy the snippet below and replace the contents of the Class1.cs file that was automatically created in the Numbers directory. I specify the results directory which I'll copy out later and specify a trx logger to get a VSTest results file. Unit test coverage and continuous testing. Note the Global Tool method doesn’t require adding the coverlet.msbuild nuget package to the project. The xUnit test project template already integrates with coverlet.collector by default. Tip: If you're having trouble with the xUnit test runner, make sure to have at least version 1.0.0-rc2-build10025 of the dotnet-test-xunit package referenced. The dotnet test command is used to execute unit tests in a given project. Use dotcover cover coverage.xml to run the coverage with the specified parameters.. Examples use code from .NET Core integration testing and mock dependencies post. you will get the following result: In the first column from left to right we can see the list of modules covered. In Jenkins, four plugins are required: 1. xUnit Pluginto evaluate test results 2. So, there was no choice “Mac or Linux or Windows”. First, we calculate the test coverage and output a coverage.coverlet.xml file. Basic scenario for .NET Core. From the command prompt, change directories to the XUnit.Coverlet.Collector project, and run the dotnet test command: The "XPlat Code Coverage" argument is a friendly name that corresponds to the data collectors from Coverlet. Well, this test would cause the runtime to test the conditional and then to execute the return x/y statement, thus executing two-thirds of the method. Last week I blogged about "dotnet outdated," an essential .NET Core "global tool" that helps you find out what NuGet package reference you need to update..NET Core Global Tools are really taking off right now. It's a very simple app): I'm guessing that a similar approach for code coverage can be attained. To add Coverlet to your test project use the following command. Examples use code from .NET Core integration testing and mock dependencies post. So I’m vesting more time learning tools and processes around Microsoft tools. Open both of the UnitTest1.cs files, and replace their contents with the following snippet. > dotnet add package coverlet.msbuild This article discusses the usage of code coverage for unit testing with Coverlet and report generation using ReportGenerator. To use coverlet and extract code coverage, this line does the trick: Azure DevOps. It is common to require developers to achieve code coverage of at least 80%. Let’s say this was the only method in our codebase. Let’s also say that we wrote a single unit test, from which we invoked Divide(2, 1) and asserted that we should get back 2.. We would then have 67% code coverage. Unit test coverage and continuous testing. The first way to generate a report that I’ll cover uses a “per-project tool”, essentially this is a Nuget package that is added to the project in a slightly different way. To analyze the test cases, add task for Dotnet Core and configure it to run Test Commands. Below you'll find language- and tool-specific analysis parameters for importing coverage and execution reports.  •  Had the same issue and in my case the problem was that the package reference "coverlet.msbuild" was not properly added by Visual Studio to the *.csproj file. For .NET Core projects, the Console Runner provides a separate cover-dotnet command (or a shorter version dotnet).It runs dotnet.exe under coverage analysis (as if you specified the path to dotnet in --TargetExecutable). Running the above command will produce the following: Per-project tools are pretty useful, and great for build servers. Now that you're able to collect data from unit test runs, you can generate reports using ReportGenerator. So, there was no choice “Mac or Linux or Windows”. In the test task you have to add –collect:”Code Coverage” for the task to add a logger for code coverage. This script test the second test project called StrikesRepository.Test You need to specify the report which is specified the last one. That can be done by going to your command line (I prefer Powershell) and running: After installing Coverlet, you can run dotnet tool list -g and verify it was installed, as well as view any other Global Tools you may already have installed. The first tool is called Coverlet which generates the code coverage as I wanted and it’s also working with .NET Framework. The XML file contains the results. But SonarQube needs a .coveragexml and does not understand the .coverage file format. As part of the dotnet test run, a resulting coverage.cobertura.xml file is output to the TestResults directory. 2020 dotnet test /p:AltCover=true In the default operation it will produce OpenCover format output in a file coverage.xml (or in the case of multiple target frameworks, and from release 4.0.600, files of the form coverage.$(TargetFramework).xml for each such target) in your project directory. In short, we build, test and publish the app with the microsoft/dotnet:2.2-sdk base image, before copying over the binaries to the microsoft/dotnet:2.2-aspnetcore-runtime image. The XML file contains the results. We’ve implemented what we already had. From your console run the following (from your test project’s directory): This command assumes that you’ve got your coverage data store in the sub-directory TestResults, and that you’ve got a coverage.cobertura.xml file (you will if you’ve been following along). Template already integrates with coverlet.collector by default get started into.NET Core NuGet. Analysis data, you must choose your criteria and minimum threshold ): I 'm assuming GitHub Actions that done. Help to ensure functionality, and replace the contents of the dotnet sln command: this command is coverage. Core project as a feature of the amount of code coverage on your dev.
