Lo que serás capaz de hacer
Unit Testing is a must-have skill and this video course is about unit testing. If you take this video course, you will learn how to test your Java code using JUnit 5 and Mockito framework . This video course is for beginners and you do not need to have any prior Unit testing knowledge to enrol in this course. JUnit 5 in Different Java projects There are different Java projects, build tools and development environments. In this course, you will learn how to create a new project and configure JUnit 5 support for different types of projects, using different development environments and build tools. You will learn how to create a Unit test in: IntelliJ IDEA and Eclipse Development environments. You will learn how to create a Unit test in: Regular Java project , Maven -based Java project, Cradle -based Java project. Course Overview This video course teaches Unit and Integration testing with Java from the very beginning and covers many advanced topics as well. By the end of this course, you will learn: JUnit 5 basics , and JUnit 5 advanced topics. Once you become familiar with JUnit 5, you will learn to use: Test-Driven Development(TDD) You will then learn to use another very popular Test framework for Java called: Mockito You will also learn how to write: Spring Boot integration tests, and Use Testcontainers to integrate real, containerized services(like databases) into your Java application tests, making sure your test scenarios are realistic without complex setup. and how to test API endpoints using REST Assured . By the end of this course you will learn and be able to use all of the following: Create Unit Tests in IntelliJ, Create Unit Tests in Eclipse, Run unit tests using Gradle, Run Unit Tests using Maven, Use @DisplayName annotation, Use JUnit assertions, Test for Exceptions, Use Lifecycle methods (@BeforeAll, @BeforeEach, @AfterEach, @AfterAll), Run unit tests in any order you need: (Random, Order by Name, Order by Index), Disable Unit test, Repeated Tests with @RepeatedTest annotation, Parameterized tests with @Parameterized annotation @ValueSource, @MethodSource, @CsvSource, @CsvFileSource Change Test Instance lifecycle with @TestInstance (PER_CLASS, PER_METHOD) Learn to Mock objects with Mockito's @Mock annotation, Learn to user Mockito's argument matches, Mockito method stubbing, Mockito Exception stubbing, Verify method call, Call Real Method, Do nothing when a method is called, Write integration tests for Spring Boot applications, and more...
