如何解决'[TestNG] No tests found. Nothing was run'

Question

我正在尝试使用Eclipse IDE通过TestNG运行selenium。下面给出了我的代码。

package testNGtest;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.testng.Assert;
import org.testng.annotations.Test;
public class loginlogout {
public WebDriver driver;
String driverPath = "D:\chromedriver.exe";
public String BaseURL = "https://xxxx.com/login";
@Test
public void loginPage() {               

System.out.println(BaseURL);
System.setProperty("webdriver.chrome.driver", driverPath);
driver= new ChromeDriver();     
driver.get(BaseURL);
String currentUrl=driver.getCurrentUrl();
Assert.assertTrue(currentUrl.contains("/login"));
}
}

当我将这个测试作为testNG测试运行时，它显示[testNG]未找到任何测试。没有运行任何内容。但当我只使用运行时

System.out.println(BaseURL);

它显示BaseURL，但在添加其余代码时，显示未找到任何测试。我使用的是chrome浏览器版本91.0.4472.124和chrome驱动程序版本，我从https://chromedriver.storage.googleapis.com/index.html?path=91.0.4472.101/并将其保存到我的D驱动器中。在我的项目中，我添加了两个jar文件"client-combined-3.141.59.jar和client-combinerd-3.141.59-sources.jar"作为引用库。作为测试结果，我可以看到以下

我不明白这里出了什么问题。有人能帮我吗？

Answer 1

当我在创建Java项目时将JRE部分中的JavaSE-16更改为JavaSE-1.8时，它成功运行，没有修改代码中的任何内容。

Answer 2

在子类中调用启动浏览器的父类方法。

Answer 3

我今天在项目中遇到了类似的问题。测试类本身看起来不错，但没有找到任何测试。

因此，我们在testng测试执行中进行了调试，发现NoClassDefFoundError异常在"；isTestNGClass"；方法，当通过ClassHelper类中的getAvailableMethods方法。

当抛出异常时；isTestNGClass"；方法返回false，导致类不是testng类，以便找不到测试。

引发异常的原因是基类的基类移动到另一个包并且该包不包括在pom的依赖项中。

因此，找不到这一类，因此NoClassDefFoundError，因此该类不是testng导致0个测试要处理的类。
