Able to run test file even if the class being tested is not found

After the recent update, Sublime-PHPUnit now able to run tests on both the test and the class file. But, if I open a test file and it's unable to detect where the class file is, I can't run the test. To me, I want to run the test file whether or not the class file exist, because sometimes my test file only test a bunch of functions or this extension just unable to detect the class file (the class file exists but it failed to detect it for some reason).
