--------------Tester Testing / Developer Testing---------------------------- Nature of job changes the mode of thinking and hence testers think in different mode than the developers. Developer always wants to see his code working properly. So he will test it to check if it’s working correctly. And tester tests application to make it fail in any way, and smart tester surely will test how application is not working correctly. This is the main difference in developer testing and tester testing.
