Test event handler on TextButton

Question

I am trying to write unit test the custom handler added to the TextButton via addSelectHandler .

I am adding the event handler as

public class TestClass {
    public void add(TextButton button) {
        button.addSelectHandler(new SelectHandler() {
            @Override
            public void onSelect(SelectEvent selectEvent) {
                System.out.println("This is called");
            }
        });
    }
}

Now in the test, I am trying to do the following

@Test
    public void test() {
        TextButton textButton = new TextButton();
        TestClass testClass = new TestClass(); 
        testClass.add(textButton);
        textButton.fireEvent(new SelectEvent());
    }

However, the log is never printed. I am not sure what is wrong here. Can somebody help me here?

Answer 1

You possibly need to set delayTestFinish(500);

This makes your GWT test case asynchronous.
