大家好，我刚开始学习Junit，现在遇到一个问题。写了一个简单的测试：

public class MainTests {

private List<Employee> employeeList;

@BeforeAll
public void sayHello(){
    System.out.println("hello");
}

@BeforeEach
public void listInit() {
    employeeList = new ArrayList<>();
    employeeList.add(new Employee(1, "John", "Smith", "USA", 25));
    employeeList.add(new Employee(2, "Ivan", "Petrov", "RU", 23));
}

@Test
public void parseCsv() {
    String fileName = "data.csv";
    String[] columnMapping = new String[]{"id", "firstName", "lastName", "country", "age"};
    List<Employee> list = Main.parseCSV(columnMapping, fileName);

    Assert.assertEquals(employeeList, list);

}

据我了解，我用 BeforeAll 注释标记的方法应该在所有测试开始之前工作一次（这根本不会发生）。另外，带有BeforeEach注解的方法必须在每次测试之前工作（这也根本不会发生）。不要告诉我为什么这些注解没有被处理？我的pom：
