使用 Junit 5 在测试套件中仅运行特定方法

Question

I have 2 test classes (A,B), both have 3 test methods. I put them into a test suite and want to run only specific methods (example: only the first method in all classes). For this use case in junit4 I had custom runner and this was done by passing the Runner into @RunWith(CustomRunner.class).

I am trying to migrate my junit4 test suites into junit5 test suites. I have created a test suite:

import org.junit.platform.suite.api.IncludeTags;
import org.junit.platform.suite.api.SelectPackages;
import org.junit.platform.suite.api.Suite;

@SelectClasses({com.example.junit5testexample.A.class,
com.example.junit5testexample.B.class})
@Suite
@SuiteDisplayName("junit5 suite")
public class JUnit5TestSuiteExample {

}

How can I now filter the methods? Should I use Extensions and @ExtendWith? If so, which extension would you recommend?

Tried with providing custom class implementing ExecutionCondition however this does not work and I am not sure why. Am I missing something or is the whole approach wrong?

public class RunMethodCondition implements ExecutionCondition { 

    @Override 
    public ConditionEvaluationResult evaluateExecutionCondition(ExtensionContext context){
        final Method testedMethod = context.getTestMethod().get();
        if(testedMethod.getName()=="Atest1"){
            return ConditionEvaluationResult.enabled("enabled");
        }
        return ConditionEvaluationResult.disabled("disabled");
    }

}

and my test suite:

@SelectClasses({com.example.junit5testexample.A.class,
com.example.junit5testexample.B.class})
@Suite
@ExtendWith(RunMethodCondition.class)
public class JUnit5TestSuiteExample {

}

From junit docs: "An ExecutionCondition is evaluated to determine if a given container or test should be executed based on the supplied ExtensionContext."
