4.0.0 What is new?

Assert.That

MSTest v4 adds a new type of assertion, that allows you to write any expression, and it will inspect the result to give you more information on failure. Providing a very flexible way to assert complicated expressions. Here a simple example:

[TestClass]
public sealed class Test1
{
    [TestMethod]
    public void TestMethod1()
    {
        var animal = "Tiger";
        var zoo = new Zoo();
        Assert.That(() => zoo.GetAnimal() == animal);
    }
}

public class Zoo
{
    public string GetAnimal()
    {
        return "Giraffe";
    }
}

Assert.That(() => zoo.GetAnimal() == animal) failed.
Details:
    animal = "Tiger"     
    zoo.GetAnimal() = "Giraffe"

CallerArgumentExpression

CallerArgumentExpression is consumed by all assertions, to make them aware of the expressions used in the assertion. In the example below, we now know what both the expected and actual values are. But also what value they come from, giving us opportunity to provide better error messages:

[TestClass]
public sealed class Test1
{
    [TestMethod]
    public void TestMethod1()
    {
        string animal = null;
        Assert.AreEqual("Giraffe", animal);
    }
}

* Fix writing warnings outside of appdomain by @nohwnd in https://github.com/microsoft/testfx/pull/5371

## Microsoft.Testing.Platform

* Add (alpha) Azure DevOps extension to report errors by @nohwnd in https://github.com/microsoft/testfx/pull/5260
* Kill testhost if writing hang dump fails by @Youssef1313 in https://github.com/microsoft/testfx/pull/5538

We've also improved the `dotnet test` experience in dotnet SDK, especially around Retry plugin experience, and started dogfooding the experience in our own repository. Please check out how to enable the new `dotnet test` experience for Microsoft.Testing.Platform in net10 by [following this link](https://learn.microsoft.com/en-us/dotnet/core/testing/unit-testing-with-dotnet-test#microsofttestingplatform-mtp-mode-of-dotnet-test), and help us dogfood it.

- This release adds support for generic test methods.
- This release adds few new analyzers.
- We added [`MSTestAnalysisMode`](https://learn.microsoft.com/en-us/dotnet/core/testing/mstest-analyzers/overview#mstestanalysismode). We encourage you to set this property to at least `Recommended`.
- This release adds `RetryAttribute`
- [Microsoft.Testing.Extensions.TrxReport](https://www.nuget.org/packages/Microsoft.Testing.Extensions.TrxReport) and [Microsoft.Testing.Extensions.CodeCoverage](https://www.nuget.org/packages/Microsoft.Testing.Extensions.CodeCoverage) are now a dependency of MSTest metapackage

## Announcements

[MSTest.Analyzers](https://www.nuget.org/packages/MSTest.Analyzers) is now a transitive dependency of [MSTest.TestFramework](https://www.nuget.org/packages/MSTest.TestFramework) and thus no longer needs to be manually installed.

Note: The only rules enabled by default as warnings, which could potentially cause build errors when updating MSTest, have been carefully selected and thoroughly validated. These rules specifically address real runtime issues related to the usage of MSTest, ensuring that no purely stylistic or low-impact analyzers are enforced by default.

## MSTest

### New and improved analyzers

We've added more code analyzers to help you prevent mistakes, and to ensure a consistent code style of your tests. 

One example of a new analyzer that was added in 3.4.0 is  `MSTEST0024: Do not store TestContext in static members`. This analyzer has `info` severity by default, and will show a message, when you store `TestContext` in a static member in your class. This is not recommended, and you should be using a `TestContext` property instead:

![image](https://github.com/microsoft/testfx/assets/5735905/ab0f95c3-f83e-47b9-a995-87161cb6a61c)

The other analyzers added in this release:

* MSTEST0017: Assertion arguments should be passed in the correct order by @Evangelink in [#2256](https://github.com/microsoft/testfx/pull/2256)
* MSTEST0019: Prefer TestInitialize over ctor by @Evangelink in [#2580](https://github.com/microsoft/testfx/pull/2580)
* MSTEST0020: Prefer ctors over TestInitialize methods by @Evangelink in [#2582](https://github.com/microsoft/testfx/pull/2582)
* MSTEST0021: Prefer Dispose over TestCleanup methods by @Evangelink in [#2585](https://github.com/microsoft/testfx/pull/2585)
* MSTEST0022: Prefer 'TestCleanup' methods over Dispose by @Evangelink in [#2586](https://github.com/microsoft/testfx/pull/2586)
* MSTEST0023: Do not negate boolean assertions by @Evangelink in [#2594](https://github.com/microsoft/testfx/pull/2594)
* MSTEST0024: Do not store TestContext in static members by @Evangelink in [#2597](https://github.com/microsoft/testfx/pull/2597)
* Add PreferAssertFailOverAlwaysFalseConditionsAnalyzer by @Youssef1313 in [#2799](https://github.com/microsoft/testfx/pull/2799)

If you've just learned about MSTest analyzers, please also check out the [analyzers that were added in previous releases](https://learn.microsoft.com/dotnet/core/testing/mstest-analyzers/overview). They will help you ensure that your test classes and test methods are recognized by MSTest and are not accidentally ignored.

The analyzers are automatically installed with the [MSTest](https://www.nuget.org/packages/MSTest/) NuGet meta-package. But can also be installed separately using the [MSTest.Analyzers](https://www.nuget.org/packages/MSTest.Analyzers/) NuGet package.

### More timeout options

Timeout can now be specified on all fixture methods, including ClassCleanup, AssemblyCleanup, TestCleanup and TestInitalize. In this case I want my `[ClassCleanup]` to time out after 1 second:

![image](https://github.com/microsoft/testfx/assets/5735905/517bd606-36f8-4096-9e30-e8b88580f46c)

Alternatively timeouts can be specified through runsettings. For example like this: 

```xml
<RunSettings>
  <MSTest>
    <ClassCleanupTimeout>1000</ClassCleanupTimeout>
  </MSTest>
</RunSettings>

Better errors on data mismatch

When you provide data that don't match your test method signature, the test will fail with an informative message, rather than just "Parameter count mismatch.".

2.2.9

Parallel output

🙇 Shout out to @SimonCropp, for bringing this functionality to XUnit in his https://github.com/SimonCropp/XunitContext project. And being an inspiration for implementing this.

MSTest 2.2.9 captures all Console output and attaches it to the correct test, even if you are running tests in parallel. This output is captured from your test code as well as from the tested code. And it requires no special setup.

Before

In 2.2.8, test output is scattered among tests, in our example, one unlucky test gets all the output of other tests just mixed together:

After

With 2.2.9, each output is correctly attached to the test that produced it:

Also notice that we are also capturing debug, trace and error. And we are not awaiting the FastChild method, and the output is still assigned correctly. Souce code.

Limitations

Due to the way that class and assembly initialize, and cleanup are invoked, their output will end up in the first test that run (or last for cleanup). This is unfortunately not easily fixable.

alexyorke · 2026-06-29T17:16:11Z

Tried the minimal local fix path before merging. I combined this adapter bump with #18 so both MSTest packages were at 4.2.3, restored and built locally, and the test project still failed at execution time on net6.0 with Method not found: 'System.Nullable<System.Boolean> Microsoft.VisualStudio.TestPlatform.ObjectModel.Utilities.AssemblyHelper.DoesReferencesAssembly(...)'. I also tried newer Microsoft.NET.Test.Sdk versions, but current 17.14.1 and 18.7.0 builds now reject net6.0 outright. Closing this because the repo's current net6.0 test stack is not compatible with MSTest 4.x without a broader framework/test-platform upgrade.

dependabot · 2026-06-29T17:16:23Z

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
