当Selenium WebDriver中的Assert条件失败时无法继续

Question

我想要在Selenium WebDriver脚本中的Assert条件失败时继续执行直到结束。在我的代码中，当Assert条件失败时，它将停止执行其余的代码。

这是我写的代码。需要帮忙。

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通过代码被认为是不好的做法（你捕捉异常，写一个错误信息，并继续处理）。

而不是使用assertEquals的，你可以直接检查条件：

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

另外，如果你仍然想在测试失败时打印的附加信息（并停止在测试进一步检查）时，Asserts通常提供了可选的最后一个参数的重载传达这样的信息时，该测试失败：

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

Answer 2

的JUnit有一个名为ErrorCollector该CA规则n用于在执行结束时收集关于测试和报告的渐进统计信息。

不结合断言和ErrorCollector，你会如果你的测试从声明

未能在测试结束任何故障将被收集并在JUnit输出集中上市失去ErrorCollector信息。

     collector.checkThat(new Object(), IsNull.notNullValue()); 
     try { 
      throw new Exception("Demonstration Exception in collector"); 
     } catch (Exception ex) { 
      collector.addError(ex); 
     } 
     collector.checkThat("Status does not match!", true, Is.is(true)); 
     System.out.println("Done."); 
    } 

    /**

    @Test 
    public void testErrorCollectorWithAssert() { 
     collector.checkThat("These things don't match", new Object(), IsEqual.equalTo(new Object())); 
     collector.checkThat(new Object(), IsNull.notNullValue()); 
     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."); 
    } 

} 

规则必须：

• 被注解为@rule
• 声明在您的测试公共。

建议的解决方案：

在你列出你上面应该删除try/catch块，并使用是匹配器，而不是org.junit.Assert.assertEquals的情况下：

@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. 
} 

祝你好运！
