How to test listener class methods using JUnit?
807603Jan 28 2008 — edited Jan 28 2008Hello,
I have to test objects returned by a listener class's "xxxchanged" or "xxxperformed" method.
I want to do this by adding the listener to an object and performing the appropriate actions that triggers an event in the listener.
Then AFTER a callback has been received, I want to obtain and run some assertions on the object obtained by the xxxchanged method.
Example: Test ActionListener class
1. Instantiate a JButton
2. Add ActionListener to it
3. Press the button
4. Check that actionPerformed method got called
5. Assert fields of ActionEvent object passed to actionPerformed method
I am not sure how to do this using JUnit.
Please advice.
Thanks,
