I wanted to write a unit test for an extension I developed. In order to do so, I wanted to test the example test case.

I can run all unit tests with arc unit --everything but I cannot run the example test case.

At the link, this is suggested

phabricator/ $ arc unit src/infrastructure/testing/testcase/
 PASS   <1ms*  testAllIsRightWithTheWorld

However, the folder testcase does not exist

phabricator/ $ tree src/infrastructure/testing/
src/infrastructure/testing/                                                       
├── fixture                                                                            
│   └── PhabricatorStorageFixtureScopeGuard.php                                              
├── PhabricatorTestCase.php                                                                  
└── __tests__                                                                                      
    └── PhabricatorTrivialTestCase.php                 

Trying to run the test with arc unit src/infrastructure/testing/__tests__ returns No tests to run.

How can I run this test successfully? I also copied the test PhabricatorTrivialTestCase.php to the src/extensions/__tests__ folder because this is where I want to drop my Unit tests for the extension but this also did not run the test.

Phabricator, libphutil and arcanist repositories have been updated today.
