    Great video, but I have a question. Why don't you validate the parameters in the setters and the constructor of Contact, but use separate validation methods for this purpose. Those methods may not be called at all, then the object will be in an incorrect state.

    Why does the AfterAll and BeforeAll have to have a static before the @TestInstance is implemented?

    • @anirudhc426
      @anirudhc426 Před 3 lety +5

      This answer might be 3 months too late, but leaving it here so that it might help someone who has the same question.
      According to what he said in the video, the methods with @AfterAll and @BeforeAll annotations are called before the test class is initiated, i.e, before an object for the class is created. To call a method without creating an object of the class, it needs to be static.

    You don't have the test directory set up in your starter project and you already have one set up in the video without explaining how to. This is really confusing.

    • @natnaelberhane3141
      @natnaelberhane3141 Před 7 měsíci

      Go into the class you want to test and just click ctrl + shift + T. If your IDE is intellij, it'll automatically create the test directory.

    Is JUnit5 really better than JUnit4 ?
    Having a single jar is still better than having granular structure requiring ugly maven projects.

    Spock(in groovy) is much better than JUnit. Data Tables are amazing feature and you will never go back to JUnit or Jest or any other language's framework. Write your code in java, kotlin etc, but write tests in groovy(spock).

    • @natnaelberhane3141
      @natnaelberhane3141 Před 7 měsíci

      Think about it as short form of executing code instead of declaring and creating it's own class. If you don't use the code more that once, you can do sth like that. In the example of this video, it's used to create the method that throws the error. () -> {// code goes here}

    By default, the Lifecycle of a Test class is PER_METHOD, so, after each test method is executed, the constructor of the Test class is called. This can be changed by using the @TestInstance(TestInstance.Lifecycle.PER_CLASS). Mentioning as additional point Just in case.
