I'm running in VS 2022 with .NET Framework 4.8
I'm referencing NuGet packages MsTest.TestAdapter and MsTest.TestFramework 2.2.10.
I'm getting this error for a lot of tests
(MyClassName).MyClassInitialize has wrong signature. The method must be static, public, does not return a value and should take a single parameter of type TestContext.
The class does have the correct signature:
[ClassInitialize()]
public static void MyClassInitialize(TestContext context)
{
...
}
It runs ok locally but when it runs in the build many tests fail with this error. Any ideas what might be causing this?
Maybe the build environment uses a different version of frameworks.

Hello, can you tell me what the build environment is?
I'm not sure I can be much help - the builds were working up until last Thursday - I asked the guy who runs the builds and he said nothing had changed. I don't know the .net framework used to run the builds, in the end I just rewrote the tests in xUnit and got them working that way.
See my template project, the code for test are broken down to use a partial class here and the main test class uses this class.
Making it a partial class didn't make any difference - I am still getting the same error in the builds.
I added some reflection just to see what was reported during the running of the tests in the build.
This is the signature reported during the running of the tests
public static void MyClassInitialize(Microsoft.VisualStudio.TestTools.UnitTesting.TestContext context)
This is the error for that method
MyClassInitialize has wrong signature. The method must be static, public, does not return a value and should take a single parameter of type TestContext
There is also a second failure in the tests which might be a clue as to what is going on.
This test has an expected exception:
[TestMethod]
[ExpectedException(typeof(NotSupportedException))]
Yet the test fails with exactly this exception:
Test method (testname)_ThrowsNotSupportedException threw exception:
System.NotSupportedException
It is as if the testing framework can't read the attributes of the tests?
This isn't really an answer but it is how I fixed the problem - I rewote the tests in xUnit and used IClassFixture<T> instead of ClassInitialize.

I got this error when adding a new test class file to an existing unit test project. It was a copy/paste of an existing one and the original still works. The new one though, gets this error. Even though it is identical to what the error says it should be... So, the best way to resolve this is to use a different unit test library? Way to go Microsoft.
