Question

我是Selenium的新手，使用testNG框架。以下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）我认为在配置方法中进行断言不是一个好习惯。而是在每种测试方法中做它们。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);
    }*/
}

当我运行它时，我看到来自softAssert.assertAll()的{{1}}调用也执行softAssertionTest2()中的断言，复制断言。如何断言只能断言一次？

Q2）是否以正确的方式将错误追加到softAssertionTest1()，还是建议在verificationErrorString中添加这些错误？

Answer 1

如何断言只断言一次？

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

是以正确的方式将错误追加到verificationErrorString还是建议在HashMap中添加这些错误？

你永远不应该用try..catch块包装你的断言，因为它会导致你吞噬异常并且它会为你的测试增加很多样板代码。如果您的意图基本上是捕获验证消息，那么您应该考虑在哪里进行子类化org.testng.asserts.SoftAssert：

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

Selenium - Testng：要在每个方法内部或@afterTest内部调用SoftAssert
