當Selenium WebDriver中的Assert條件失敗時無法繼續

Question

我想要在Selenium WebDriver腳本中的Assert條件失敗時繼續執行直到結束。在我的代碼中，當Assert條件失敗時，它將停止執行其餘的代碼。

這是我寫的代碼。需要幫忙。

try 
{ 
    Assert.assertEquals(false, status); 
} 
catch(Exception Ex) 
{ 
    System.out.println("Disabled user can register for workshop : case Failed "); 
} 

Answer 1

使用exceptions to control the flow of logic通過代碼被認爲是不好的做法（你捕捉異常，寫一個錯誤信息，並繼續處理）。

而不是使用assertEquals的，你可以直接檢查條件：

if (status == false) { 
    System.out.println("Disabled user can register for workshop : case Failed "); 
} 

另外，如果你仍然想在測試失敗時打印的附加信息（並停止在測試進一步檢查）時，Asserts通常提供了可選的最後一個參數的重載傳達這樣的信息時，該測試失敗：

Assert.assertEquals(false, status, 
"Disabled user can register for workshop : case Failed "); 

Answer 2

的JUnit有一個名爲ErrorCollector該CA規則n用於在執行結束時收集關於測試和報告的漸進統計信息。

不結合斷言和ErrorCollector，你會如果你的測試從聲明

未能在測試結束任何故障將被收集並在JUnit輸出集中上市失去ErrorCollector信息。

     } catch (Exception ex) {

     } 
     collector.checkThat("Status does not match!", true, Is.is(true)); 
     System.out.println("Done."); 
    }

    @Test

     try { 
      throw new Exception("Demonstration Exception in collector"); 
     } catch (Exception ex) { 
      collector.addError(ex); 
     } 
     //Test stops here. You won't see "done", nor will you see any of the previous ErrorCollector status' 
     Assert.assertTrue(false); 

     collector.checkThat("Status does not match!", true, Is.is(true)); 
     System.out.println("Done."); 
    } 

} 

規則必須：

• 被註解爲@rule
• 聲明在您的測試公共。

建議的解決方案：

在你列出你上面應該刪除try/catch塊，並使用是匹配器，而不是org.junit.Assert.assertEquals的情況下：

@Rule 
public ErrorCollector collector = new ErrorCollector(); 

@Test 
public void testSomething() { 
    boolean status = doStatusEval(); 
    collector.checkThat("Disabled user can register for workshop", false, Is.is(status)); 
//Continue adding things to the collector. 
} 

祝你好運！
