java - JUnit 测试代码在检查异常后停止执行

Question

这是我的测试:

  import org.junit.rules.ExpectedException;
  @Rule
  public final ExpectedException exception = ExpectedException.none();

  @Test
  public void testSearch() {
      List<Integer> myList = Arrays.asList(new Integer[] {1, 2, 4, 6, 3, 1, 2});  
      exception.expect(NoSuchElementException.class);   
      SimpleSearch.search(myList, 5);
      System.out.println("here");

      exception.expect(NoSuchElementException.class);  
      assertEquals(1, SimpleSearch.search(myList, 22));
}

当我运行它时，它说它运行了 1/1 但它不打印 here 并且它不做任何断言或运行 SimpleSearch.search(myList , 5); (异常被捕获后).

如何在捕获异常后让它继续(我想在同一个 testSearch 函数中执行)？

在这种情况下，您的测试应该更细化并拆分出 2 个测试用例

  @Test(ExpectedException=NoSuchElementException.class)
  public void testSearch_NotFound() {
      List<Integer> myList = Arrays.asList(new Integer[] {1, 2, 4, 6, 3, 1, 2});  
      SimpleSearch.search(myList, 5);
  }

  @Test
  public void testSearch() {
      List<Integer> myList = Arrays.asList(new Integer[] {1, 2, 4, 6, 3, 1, 2});  
      assertEquals(1, SimpleSearch.search(myList, 22));
  }
