Ғылым және технология

Learn about what a mocking framework is used for with unit testing, when we it would want to use it, and how we can use the Mockito framework within our tests.

    Thanks a lot, the most comprehensive video on youtube, watched like 3 other before this one... everywhere lots of unneeded information, unnecessary repetitions of useless information. Your video is exactly on the topic, nothing more, nothing else. Please make more videos of that kind :)

    Thanks, nobody explain what when and thenReturn do, and is very simple, is, when you executed this Injected Class, simulate (thenReturn) with the data is in the setup or init or before method annotated.

    Very helpful videos. Thank you again. One thing I faced was mock object could not be created. I was getting: Unable to make protected final java.lang.Class java.lang.ClassLoader.defineClass(java.lang.String,byte[],int,int) throws java.lang.ClassFormatError accessible: module java.base does not "opens java.lang" to unnamed module Thank I had to add jvm argument: --illegal-access=warn --add-opens java.base/java.lang=ALL-UNNAMED

    Like I am test testing the business service layer of my spring rest web project with Spring data jpa . So should I create mock stubs for repository interfaces for testing the Business layer which is interacting with DAO layer?
