-Functions that abruptly terminate a test, such as the Fatal, Fatalf, FailNow, and
-Skip{,f,Now} methods of *testing.T, must be called from the test goroutine itself.
-This checker detects calls to these functions that occur within a goroutine
-started by the test. For example:
-
-func TestFoo(t *testing.T) {
