使用TestNG的selenium automation中出现java“未找到任何测试。未运行任何内容”错误

Question

下面是我在eclipse中使用selenium编写的代码

import org.openqa.selenium.support.ui.ExpectedConditions;
import org.openqa.selenium.support.ui.WebDriverWait;
import org.testng.annotations.Test;
import org.openqa.selenium.By;
import org.openqa.selenium.Keys;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.firefox.FirefoxDriver;
class GoogleSearchTest {

    @Test
    public static void main(String[] args) throws InterruptedException {
        System.setProperty("webdriver.gecko.driver","C:\\Users\\acer\\Downloads\\selenium\\geckodriver.exe");
        WebDriver driver =new FirefoxDriver();
        driver.get("https://www.google.com/");
        WebElement we1 = driver.findElement(By.name("q"));
        we1.sendKeys("GMAIL");
        we1.sendKeys(Keys.ENTER); 
        WebDriverWait wait1 = new WebDriverWait(driver, 5);
        wait1.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//h3[text()='E-mail - Sign in - Google Accounts']"))).click();
        Thread.sleep(10000); 
        driver.findElement(By.id("identifierId")).sendKeys("2017cs102@stu.ucsc.cmb.ac.lk");
        driver.findElement(By.xpath("//*[@id='identifierNext']/div/span/span")).click();
        Thread.sleep(10000);
        driver.findElement(By.name("password")).sendKeys("mmalsha425@gmail.com");
        driver.findElement(By.xpath("//*[@id='passwordNext']/div/span/span")).click();

    }

}

它给出了以下错误

[TestNG] No tests found. Nothing was run
Usage: <main class> [options] The XML suite files to run

我已经安装了TestNG插件。我能做些什么来解决这个问题

Answer 1

您不需要编写main()方法，TestNg可以自己完成

class GoogleSearchTest {
    @Test
    public void test() throws InterruptedException{
        //your code here
        .....
    }
}

如果您想从main()呼叫，只需：

import org.testng.TestNG;

public class Master {
    public static void main(String[] args) {
        TestNG testng = new TestNG();
        testng.setTestClasses(new Class[] { GoogleSearchTest.class });
        testng.run();
    }
}

但是请注意，在GoogleSearchTest类中，不要把public static void main放在@Test

Answer 2

更改主函数名。您不应该在使用TestNG时使用它

@Test
public void test() throws InterruptedException {
    System.setProperty("webdriver.gecko.driver","C:\\Users\\acer\\Downloads\\selenium\\geckodriver.exe");
    WebDriver driver =new FirefoxDriver();

Answer 3

此错误消息

[TestNG] No tests found. Nothing was run
Usage: <main class> [options] The XML suite files to run

。。。这意味着TestNG没有发现任何测试，因此没有执行任何测试

TestNG

TestNG是一个基于注释的测试框架，它需要一个标记注释类型来指示一个方法是一个测试方法，并且应该由测试工具运行。因此，当使用testng时，就像使用annotations一样，您不必显式地调用main()方法

解决方案

简单的解决方案是用测试方法名替换main()方法，例如test()，并保留@Test注释如下：

// your imports

class GoogleSearchTest {

    @Test
    public void test() throws InterruptedException {
        System.setProperty("webdriver.gecko.driver","C:\\Users\\acer\\Downloads\\selenium\\geckodriver.exe");
        // other lines of code
    }
}
