If the test at 51:00 fails, in the pom.xml file, try changing the artifactId from mockito-all to mockito-core, and changing the version from 1.10.19 to 4.2.0.

[@vishwa.ingale]

Thanks

[@arnabbumba]

Thanks. It solves the issue.

[@123cheke]

Thank you, I had the same issue.

[@edwarddoyle2509]

Excellent overall. I found that the video started with the basics of JUnit. About 25 minutes in it introduces stubs, then it introduces a better way - mocks. The last third really takes off with the introduction of Mockito. Starts off basic concepts and ends up very advanced.

[@sandy4799]

After a lot of reading blogs and watching videos, I saw this video and I now have a clear understanding of the differences between stubs and mocks. Thanks for making this video.

[@AmitSharma-fw2ng]
