Error: Call to undefined method DateFormatterTest::getMock()

Question

Update: with $stub = $this->createMock('Config'); this example works, but I get a warning:

OK, but incomplete, skipped, or risky tests! Tests: 1, Assertions: 0, Risky: 1.

In the video-tutorial this example works without any warnings. Is it possible to fix this warning?

---

I can't find why I am getting this error and how to fix it. This code is from a video tutorial. And in the Video it works. Maybe a typo?

getMock() no longer exists in PHPUnit 6. Use createMock() or getMockBuilder() instead.
