JUnit and Mockito Crash Course from Udemy

Sample of the reviews:

Very good teacher, knows the material. Hands on exercises that are quick to write, but very useful to support the learning of the course content. I'll keep these tiny projects and I'll refer to it often when coding. I've learned a lot about JUnit testing and Mockito, but also about other tools useful in software unit testing: Ex: Spring, shortcuts in Eclipse. - Guy Audet

Very well explained, to the point, on short interval to grasp the content. Every lecture has purpose achieved. Simple examples. Really nice course. - Kaushal Trivedi

I enjoyed the course. The Course is well structured, principles were clearly explained, the sound and picture quality was good. I recommend the course to everyone who would like to begin with java unit testing. Thanks, Bharath. - Mario Banay
