The issue is in the backlog of the relevant team and is prioritized by them.

This is a corner-case of how test filters are handled on the command-line and it is an expected behaviour.

When parsing a command-line test patterns, Gradle expects a test filter with the following format: [className][.[methodName]]?
If the method name is missing then a .* pattern is appended to the final test filter pattern. TestLauncher is less permissive as it provides explicit API for selecting test tasks and test methods.

In the reproducer, you can run select the test with its fully-qualified name

.withJvmTestClasses("com.example.project.NestedTests$NestedClassB$ADeeperClass")

Or you can work around the issue by using the same wildcard approach that is used by the command-line:

.withJvmTestClasses("com.example.project.NestedTests.*")

Hi @donat,

Confirmed that using com.example.project.NestedTests$NestedClassB$ADeeperClass can make it work. But it still not works when appending .*, the error says:

Caused by: org.gradle.api.tasks.testing.TestExecutionException: No matching tests found in any candidate test task.
    Requested tests:
        Test class com.example.project.NestedTests.*

There's a typo in my previous message. The extra suffix should be * (instead of .*):

.withJvmTestClasses("com.example.project.NestedTests*")

It works, thank you @donat.

Maybe consider to add this trick to the javadoc of withJvmTestClasses?
