1 language server generate and resolve junittest codelens
2 investigate junit interface for invoking a test in commandline
3 customized junit test runner which could run/debug test suites and print test structure and test duration, test status(failure with stacktrace)
4 vscode extension adds commands for junittest run/debug codelens

Regarding 2. JUnitCore allows for running a single class. But it looks like you might need another solution in order to run a specific method.

There's also a --filter parameter, but I don't know that JUnit natively has support for running a single method. Relevant PR: junit-team/junit4#647

@claycephas JunitCore doesn't provide a way to run a single test, so we have to provide a customized junit runner. About how to run a single test, i 'm thinking to use this method : http://junit.sourceforge.net/javadoc/org/junit/runner/Request.html#method(java.lang.Class, java.lang.String)

Yes, I think you could use the Request class together with JUnitCore. Something like this.

When running a single method from method code lens:

new JUnitCore().run(Request.method(MyClass.class, "methodName"))

When running an entire class from class code lens:

new JUnitCore().run(Request.aClass(MyClass.class))
