我使用IRetryAnalyzer实现了失败测试用例的重试逻辑,在我的测试用例中定义了两种类型的断言-- Assert和SoftAssert。IRetryAnayzer对于正常的断言很好,但是在SoftAssert情况下不像预期的那样工作。以下是有关所面临问题的设想细节:
。
我需要保留很少的测试用例作为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。实现ListenerAdapter是为了删除重复的测试用例执行,这些测试用例被标记为跳过,作为重试实现的一部分。在下面的示例代码中,如果samplecondition1在第一次尝试中失败,即使它在第二次尝试中通过,它也会对定义的最大重试计数进行重试,并将samplecondition2标记为失败,即使它正在传递:
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);
}

我不知道您正在使用的是哪个版本的TestNG,但我似乎无法使用TestNG 7.0.0 (今天最新发布的版本)重现这个问题。
您的代码中还有另外一个问题。您将SoftAssert作为全局变量。SoftAssert通过它的实现,记住了所有的失败。因此,对于每一次重试,从第一次尝试到现在,它继续坚持所有的失败。这意味着,涉及RetryAnalyser并使用可能出现故障的RetryAnalyser的SoftAssert方法将导致该测试方法永远无法通过。
在使用SoftAssert时,应该始终在@Test方法中声明和使用SoftAssert对象,以便实例化它(因此每次重试都会重置)。
下面是您共享的同一个示例(我稍微修改了一下),它演示了这在7.0.0中运行得很好
从输出中可以看到,只有firstTestMethod (它有SoftAssert正在被重试)和secondTestMethod (有一个硬断言并且没有失败)没有被重试。
测试类(我只是改变了这一点,其他一切都是从您原来的文章中借来的)
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);
}
}
}**重试分析器,增加一些日志记录**
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.
