我在Administrator.java中寫了一個方法deleteProject(Project project),它將項目設置爲null。在此之後,我嘗試編寫一個調用deleteProject(Project project)方法的測試方法,並檢查Object項目== null。不是這種情況。我已將3個system.out.println(項目)放入方法中。如果查看輸出項目,在deleteProject(Project項目)中將項目設置爲null,但由於某些原因,它仍然以AdministratorTest打印。JUnit test刪除方法Object設置爲null後不爲空
我不明白爲什麼項目不保留爲空。
AdministratorTest.java
@Before
public void setUp() throws Exception {
admin1 = new Administrator("Sponge", "Bob", "Squarepants", "Spongy");
project = admin1.createProject(new VersionID(2, 3), "ProjectX", "Secret", new Date(93, 10, 17));
}
@After
public void tearDown() throws Exception {
admin1 = null;
project = null;
}
@Test
public void testDeleteProject() {
assertEquals("2.3", project.getVersion().toString());
assertEquals("ProjectX", project.getName());
assertEquals("Secret", project.getDescription());
assertEquals("Wed Nov 17 00:00:00 CET 1993", project.getStartDate().toString());
admin1.deleteProject(project);
System.out.println(project);
assertNull(project);
}
Administrator.java
public void deleteProject(Project project) {
System.out.println(project);
project = null;
System.out.println(project);
}
