java - Selenium -测试 : SoftAssert to be called inside each method or inside @afterTest

Question

我是 Selenium 新手，使用 testNG 框架。下面是我试图理解的代码

@Test
public void softAssertionTest() {
    try{
        softAssert.assertTrue(name.equals("HardAssertionTest"));
        softAssert.assertEquals(1, 1,"Error 1");
        softAssert.assertEquals("a","b","Error ab");
        System.out.println("Line after assertions");
    } catch (Throwable t){
        System.out.println("+++++++++++");
        verificationErrors.append(t);
        System.out.println("Verification error - method1"+ verificationErrors);
    }

}

@Test
public void softAssertionTest2() {
    softAssert.assertTrue(name.equals("HardAssertionTest"));
    softAssert.assertEquals(3, 4,"Error 3,4");
    softAssert.assertEquals("c","d","Error cd");     
    System.out.println("Line after assertions method 2");
}

@AfterTest
public void afterTest(){
    softAssert.assertAll();
    String verificationErrorString = verificationErrors.toString();
    if (!"".equals(verificationErrorString)) {
        fail(verificationErrorString);
        System.out.println(verificationErrorString);
    }
}

Q1)我读到在配置方法中进行断言不是一个好习惯。而是在每个测试方法中进行这些操作。因此我修改代码如下

@Test
public void softAssertionTest() {
    try{
        softAssert.assertTrue(name.equals("HardAssertionTest"));
        softAssert.assertEquals(1, 1,"Error 1");
        softAssert.assertEquals("a","b","Error ab");
        System.out.println("Line after assertions");
        doSoftAssert();
    } catch (Throwable t){
        System.out.println("+++++++++++");
        verificationErrors.append(t);
        System.out.println("Verification error - method1"+ verificationErrors);
    }
}

@Test
public void softAssertionTest2() {
    try{
        softAssert.assertTrue(name.equals("HardAssertionTest"));
        softAssert.assertEquals(3, 4,"Error 3,4");
        softAssert.assertEquals("c","d","Error cd");     
        System.out.println("Line after assertions method 2");
        doSoftAssert();
    } catch (Throwable t){
        System.out.println("+++++++++++");
        verificationErrors.append(t);
        System.out.println("Verification error - method2"+ verificationErrors);
    }           
}

public void doSoftAssert(){
    softAssert.assertAll();
    /*String verificationErrorString = verificationErrors.toString();
    if (!"".equals(verificationErrorString)) {
    fail(verificationErrorString);
    System.out.println(verificationErrorString);
    }*/
}

当我运行此命令时，我看到从 softAssertionTest2() 调用 softAssert.assertAll() 也会执行 softAssertionTest1() 中的断言，复制断言。我怎样才能让断言只被断言一次？

Q2) 将错误附加到 verificationErrorString 的方式是否正确，还是建议将这些错误添加到 HashMap 中？

Answer 1

How can I have assertions being asserted only once?

每个测试都应该实例化自己的SoftAssert对象，并且不应在多个 @Test 之间共享方法。

Is appending the errors to verificationErrorString the right way or is it advisable to add these errors in a HashMap?

你永远不应该用try..catch来包装你的断言。 block ，因为它可能会导致您吞噬异常，并且会在测试中添加大量样板代码。如果您的目的基本上是捕获验证消息，那么您应该查看子类 org.testng.asserts.SoftAssert您在哪里:

• 覆盖org.testng.asserts.Assertion#onAssertSuccess (如果你想捕获传递的断言)和
• 覆盖org.testng.asserts.Assertion#onAssertFailure(org.testng.asserts.IAssert<?>, java.lang.AssertionError) (如果你想捕获失败的断言)
