When a test is performed (as this snippet from the documentation):

 public void testError2() { 
    FooElement model = MyLanguageFactory.eINSTANCE.createFooElement() 
    model.setBarAttribute("barbarbarbarfoo"); 
    
    tester.validate(model).assertError(101); 
  } 

And the validator is initialized in the setUp() method like this:
		super.setUp();
		with(MyStandaloneSetup.class);
		MyJavaValidator validator = get(MyJavaValidator.class);
		EValidatorRegistrar registrar = get(EValidatorRegistrar.class);
		tester = new ValidatorTester<MyJavaValidator>(validator, registrar);

Then, no methods will be called in the MyValidator unless it's isLanguageSpecific() method is overridden and returns false.

The problem seems to be that the key org.eclipse.xtext.validation.AbstractInjectableValidator.currentLanguageName is set to an empty string in the context. Looks like it is setting that from the model's resource, but since it does not have one, the result is that the language name is empty.
