Проблемы с автоматическим обнаружением тестов с помощью TestPlatform в .NET. ⇐ C#

[Гость]

I am developing a unit testing framework with c#. I am using the official Microsoft.TestPlatform library and I have already implemented

Код: Выделить всё

ITestDiscoverer

and

Код: Выделить всё

ITestExecutor

.
What I am using to determine that a method is a test is the

Код: Выделить всё

MyTestAttribute

attribute.
MyTestAttribute:

Код: Выделить всё

[AttributeUsage(AttributeTargets.Method, AllowMultiple = false)]
public class MyTestAttribute : Attribute
{
}

TestDiscoverer:

Код: Выделить всё

[DefaultExecutorUri(Constants.ExecutorUriString)]
[FileExtension(".dll")]
internal class TestDiscoverer : ITestDiscoverer
{
public void DiscoverTests(IEnumerable sources, IDiscoveryContext discoveryContext, IMessageLogger logger, ITestCaseDiscoverySink discoverySink)
{
//Discover tests code
//If the method use MyTestAttribute is a test
}
}

TestExecutor:

Код: Выделить всё

[ExtensionUri(Constants.ExecutorUriString)]
internal class TestExecutor : ITestExecutor
{
public void Cancel()
{
//Cancel code
}

public void RunTests(IEnumerable? testCases, IRunContext? runContext, IFrameworkHandle? frameworkHandle)
{
//Run tests code
}

public void RunTests(IEnumerable? sources, IRunContext? runContext, IFrameworkHandle? frameworkHandle)
{
//Run tests code
}
}

So far everything works well, if I have a method that uses the

Код: Выделить всё

[MyTest]

attribute when I run the tests it is detected.

Код: Выделить всё

[MyTest]
public void Should_Be_A_Test()
{
//Unit test code
}

The problem is that the test is only visible in the test explorer once I run it, and not when the test is created. To better visualize the problem I am going to show a comparison with the xUnit framework, which is the behavior I want to achieve.
Creation of tests:

• MyFramework

Код: Выделить всё

[MyTest]
public void Should_Be_A_Test()
{
//Unit test code
}

• xUnit

Код: Выделить всё

[Fact]
public void Should_Be_True()
{
Assert.True(true);
}

Test explorer results:
Before running the tests

As you can see in the image, just by creating the test in xUnit it is already detected, but the methods that use

Код: Выделить всё

MyTest

are not detected.
After running the tests

Once I run the tests, it is detected and works correctly.
My question is, how can I reproduce that behavior that xUnit has?.
I tried to find how to do it in xUnit by looking at the source code but I couldn't find how to do it.
