我在 org.testng.TestNGException 线程"main"中收到错误异常：运行测试时无法从文件加载类

Question

这是我项目的testNG文件

<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd" >
<suite name="mobile-automation-framework">
<parameter name="os" value="android" />
<listeners>
<listener class-name="UITestFramework.retryLogic.RetryListener" />
<listener class-name="UITestFramework.retryLogic.TestListener" />
<listener class-name="org.uncommons.reportng.HTMLReporter"/>
<listener class-name="org.uncommons.reportng.JUnitXMLReporter"/>
</listeners>
<test name="LoginTest">
<classes>
<class name="tests.testngTests.e2e_Tests"/>
</classes>
</test>
</suite>

我的测试用例文件

package tests.testngTests;
import org.testng.annotations.*;
import IntegrationTests.coreLogic.base.*;
import IntegrationTests.coreLogic.android.*;
import UITestFramework.CreateSession;
/**
* automated test to verify login to android/iOS app.
*/
public class e2e_Tests extends CreateSession {
LoginCoreLogic loginCoreLogic;
/**
* this method instantiate required helpers depending on the platform(android or iOS)
*
* @param invokeDriver android or iOS
*/
@Parameters({"os"})
@BeforeClass
public void instantiateHelpers(@Optional("android") String invokeDriver) {
//Load Test Data

if (invokeDriver.equalsIgnoreCase("android")) {
loginCoreLogic = new AndroidLoginHelper(driver);
} else if (invokeDriver.equalsIgnoreCase("iOS")) {
//loginCoreLogic = new IOSLoginCoreLogic(driver);
}
}
/**

*
* @throws InterruptedException Thrown when a thread is waiting, sleeping,
*                              or otherwise occupied, and the thread is interrupted, either

*/
@Test(priority = 0)
public void VerifyForgotPassword() throws InterruptedException {
System.out.println("inside test 1");
}
}

错误日志

[RemoteTestNG] detected TestNG version 7.0.1
Exception in thread "main" org.testng.TestNGException: 
Cannot load class from file:

我在我的pom文件中安装了testNG插件和testng依赖项。我不知道这个错误背后的原因是什么。请让我知道解决此问题的可能解决方案。我已经重新安装了testNG插件，并且已经完成了运行，构建，清理项目

Answer 1

您需要做几件事。

• 从 pom.xml 文件中删除所有依赖项的 scope 参数
• 尝试使用以下格式替换 testng.xml 文件并在那里添加您的类，

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "https://testng.org/testng-1.0.dtd">
<suite name="Test Automation" parallel="tests">
<listeners>
<listener class-name=""/>
</listeners>
<test thread-count="5" name="Test Cases">
<classes>
<class name="com.package.yourclassname"/>
</classes>
</test>
</suite>
