OS: Android

What steps will reproduce the problem?
(1) Write a test using JUnit and the Robolectric test runner.
(2) Add some log statements:
    org.chromium.base.Log.d("nyquist", "This is great!");
(3) Run the test
    $ ./out/Default/bin/run_base_junit_tests

What is the expected result?
Logs are printed to stdout when running the test, if it fails.

What happens instead?
No logs are printed.

What do I want?
A command line argument to the junit test runner that enables something like:
- Always print logs
- Only print logs on failure
- Do not print logs (default)

Workaround available?
Yes, a developer can do this manually by adding the following statement to the test:

  @Before
  public void setUp() {
    ShadowLog.stream = System.out;
    //you other setup here
  }
