AssertionError在单元测试时调用意外的方法

Question

@RequestMapping(value = "/createTestscenario", method = RequestMethod.POST)
public String createTestscenario(@PathVariable("tdid") Integer testdesignID, @ModelAttribute("testscenario") Testscenario testscenario){

    Testdesign testdesign = this.testdesignService.getTestdesignById(testdesignID);
    testscenario.setTestdesign(testdesign);
    testdesign.getTestscenarioSet().add(testscenario);
    this.testdesignService.saveTestdesign(testdesign);

    return "redirect:/projects";
}

@Test
public void createTestscenario1() throws Exception {

    Testdesign testdesign = new Testdesign();
    testdesign.setId(1);

    Testscenario testscenario = new Testscenario();
    testscenario.setId(1);
    Testscenario testscenario2 = new Testscenario();
    testscenario.setId(2);
    Set<Testscenario> set = new HashSet<>(Arrays.asList(testscenario));
    testdesign.setTestscenarioSet(set);
    testscenario.setTestdesign(testdesign);

    EasyMock.expect(testdesignService.getTestdesignById(1)).andReturn(testdesign);
    EasyMock.replay(testdesignService);

    String test = controller.createTestscenario(1, testscenario2);

    EasyMock.verify(testdesignService);

    Assert.assertEquals("redirect:/projects", test);
}

java.lang.AssertionError: 
  Unexpected method call TestdesignServiceImpl.saveTestdesign(com.example.testclusters.model.Testdesign@28feb3fa):

EasyMock.expect(testdesignService.save(testdesign)).andReturn(..);

因为save是一个void方法。

有人知道如何修复这个单元测试吗？

Answer 1

在重播之前只需调用TestDesignService.Save(testdesign)。这就是如何设置void方法的异常。

你也可以做

testdesignService.save(testdesign)
expectLastCall();

但是expectlastcall()实际上是不必要的。它的存在只是为了执行ExpectLastCall().andThrow(new RuntimeException())等操作
