Mockito is a Mock framework for Java single-testing, but it can also be used with other single-testing frameworks in addition to JUnit. Mockito changes the behavior of a class or object, allowing us to focus more on testing the code logic without the effort of constructing the data. The basic concept Mocks can be of two types, Class and Partial,so Mockito is called spy. The behavior of changing methods on mock objects is called Stub. A Mock process is called a Mock Session, and it records all the Stubbing. It consists of three steps: +----------+ +------+ +--------+ | Mock/Spy | ===> | Stub | ===> | Verify | +----------+ +------+ +--------+ Class Mock A Class Mock changes the behavior of a Class so that the object it mocks completely loses its original behavior. Method returns default values (null, false, 0, etc.) if it is not pegged. The most basic usage is as follows: 1 2 3 4 5 6 7 8 9 10 11 12 import static org.mockito.Mockito.*; // use List.class to...
The most valuable thing you can get out of any book is a list of other books worth reading. Over time, you will find that certain books keep popping up from the "bibliography", and you should move those books to the top of the reading list. Other books will sink. Since the reading list is essentially a priority queue, you'll eventually find that some books sink so far down the queue that you may never read them again. Start by picking a broad book to give you a general idea of the subject you are aiming for. Then choose a few specific books to master the aspects of the topic that interest you. Reading the right book at the right time will have a better effect. A lot of reading can improve your reading ability. You will also improve your knowledge of the outside world through reading. For computer science, reading a lot of the latest information will be of great help to your future work and research. Reading will improve your horizon and enrich your spare time. Even if you...
https://www.baeldung.com/junit-5-migration According to this blog what I study for the Junit 4 and Junit5: JUnit 5 is a powerful and flexible update to the JUnit framework, providing various improvements and new capabilities to organize and describe test cases and to help understand test results. Upgrade to JUnit 5 is quick and easy: Just update your project dependencies and start using the new functionality. JUnit 4 bundles everything into a single JAR file. JUnit 5 consists of three sub-projects, namely JUnit Platform, JUnit Jupiter, and JUnit Vintage. 1. JUnit platform It defines TestEngine's API for developing new testing frameworks that run on the platform. 2.JUnit Jupiter It has all the new JUnit annotations and TestEngine implementations to run tests written with those annotations. 3.JUnit Vintage Support for running tests written by JUnit 3 and JUnit 4 on the JUnit 5 platform. But here are four strong reasons to start writing new test cases with JUnit 5: JUnit 5 takes advan...
