IRetryAnalyzer 为定义为 SoftAssert 的测试用例生成不正确的结果

IRetryAnalyzer produces incorrect results for test cases defined as SoftAssert

我使用 IRetryAnalyzer 为失败的测试用例实现了重试逻辑,并且有 2 种类型的断言 - 我的测试用例中定义了 Assert 和 SoftAssert。 IRetryAnayzer 对于普通断言工作正常,但在 SoftAssert 的情况下无法按预期工作。以下是有关所面临问题的场景详细信息:

我需要保留一些测试用例作为 softAssert,因为我必须继续测试 运行。例如:

@Test(retryAnalyzer = RetryAnalyzer.class, groups = { "group1" }, priority=1)
    public void TestSection1(){
        Class1.verifyingAppLaunch(); //Defined as Assert
        Class1.Test1(); //Defined as softAssert
        Class1.Test2(); //Defined as softAssert
        Class1.Test3(); //Defined as softAssert
        Class1.Test4(); //Defined as softAssert
        Class1.Test5(); //Defined as softAssert
        softAssert.assertAll();
    }

下面是 IRetryAnalyer 和 ListenerAdapter 实现的示例。实施 ListenerAdapter 是为了删除重复的测试用例执行,这些测试用例执行被标记为已跳过,作为重试实施的一部分。在下面的示例代码中,如果 samplecondition1 在第一次尝试中失败,它会重试定义的最大重试次数,即使它在第二次尝试中通过,也会将 samplecondition2 标记为失败,即使它通过:

MyTestListenerAdapter.class

import java.util.Iterator;
import org.testng.ITestContext;
import org.testng.ITestNGMethod;
import org.testng.ITestResult;
import org.testng.TestListenerAdapter;

public class MyTestListenerAdapter extends TestListenerAdapter {

    @Override
    public void onFinish(ITestContext context) {
        Iterator<ITestResult> skippedTestCases = context.getSkippedTests().getAllResults().iterator();
        while (skippedTestCases.hasNext()) {
            ITestResult skippedTestCase = skippedTestCases.next();
            ITestNGMethod method = skippedTestCase.getMethod();
            if (context.getSkippedTests().getResults(method).size() > 0) {
                System.out.println("Removing:" + skippedTestCase.getTestClass().toString());
                skippedTestCases.remove();
            }
        }
    }
}

TestRetryAnalyzer.class

import org.testng.IRetryAnalyzer;
import org.testng.ITestResult;

public class TestRetryAnalyzer implements IRetryAnalyzer {
    int counter = 1;
    int retryMaxLimit = 3;

    public boolean retry(ITestResult result) {
        if (counter < retryMaxLimit) {
            counter++;
            return true;
        }
        return false;
    }
}

TestRetryTestCases.class

import org.testng.Assert;
import org.testng.annotations.Listeners;
import org.testng.annotations.Test;

@Listeners(MyTestListenerAdapter.class)
public class TestRetryTestCases {
SoftAssert softAssert = new SoftAssert();

    @Test(retryAnalyzer = TestRetryAnalyzer.class)
    public void firstTestMethod() {
        System.out.println("First test method");
        if (samplecondition1 == true)
            softAssert.assertTrue(true);
        else
            softAssert.assertTrue(false);
softAssert.assertAll();
    }

    @Test(retryAnalyzer = TestRetryAnalyzer.class)
    public void secondTestMethod() {
        System.out.println("Second test method");
        if (samplecondition2 == true)
            Assert.assertTrue(true);
        else
            Assert.assertTrue(false);
    }
}

我不确定您使用的是哪个版本的 TestNG,但我似乎无法使用 TestNG 7.0.0(截至今天的最新发布版本)重现此问题。

您的代码中还有其他问题。您将 SoftAssert 作为全局变量。 SoftAssert 通过它的实现,记住所有的失败。因此,对于每次重试,它都会继续坚持从第一次尝试到现在的所有失败。这意味着涉及 RetryAnalyser 并使用 SoftAssert@Test 方法可能会导致该测试方法永远不会通过。

使用 SoftAssert 时,您应该始终在 @Test 方法中声明和使用 SoftAssert 对象,以便它被实例化(并因此在每次重试时重置)。

这是您分享的同一个示例(我稍微调整了一下),它证明这在 7.0.0

中工作正常

正如您从输出中看到的那样,只有 firstTestMethod(其中有 SoftAssert 正在重试)和 secondTestMethod(具有硬断言并且没有失败) 未重试。

测试class(我只改了这个,其他都是借鉴你原来的post)

import org.testng.Assert;
import org.testng.annotations.Listeners;
import org.testng.annotations.Test;
import org.testng.asserts.SoftAssert;

@Listeners(MyTestListenerAdapter.class)
public class TestRetryTestCases {
  int softAssertCounter = 0;
  int hardAssertCounter = 0;

  @Test(retryAnalyzer = TestRetryAnalyzer.class)
  public void firstTestMethod() {
    SoftAssert softAssert = new SoftAssert();
    System.out.println("First test method");
    if (softAssertCounter++ > 2) {
      softAssert.assertTrue(true);
    } else {
      softAssert.assertTrue(false);
    }
    softAssert.assertAll();
  }

  @Test(retryAnalyzer = TestRetryAnalyzer.class)
  public void secondTestMethod() {
    System.out.println("Second test method");
    if (hardAssertCounter++ < 2) {
      Assert.assertTrue(true);
    } else {
      Assert.assertTrue(false);
    }
  }
}

** 使用一些额外的日志重试分析器 **

import org.testng.IRetryAnalyzer;
import org.testng.ITestResult;

public class TestRetryAnalyzer implements IRetryAnalyzer {
  int counter = 1;
  int retryMaxLimit = 3;

  public boolean retry(ITestResult result) {
    if (counter < retryMaxLimit) {
      counter++;
      System.err.println("Retrying the test method " + result.getMethod().getMethodName());
      return true;
    }
    return false;
  }
}

控制台输出

First test method
Retrying the test method firstTestMethod
Retrying the test method firstTestMethod

Test ignored.

First test method


Test ignored.
