Question

我正在尝试使用Junit运行跨浏览器测试（从xml文件读取），我收到此错误：

**"java.lang.Exception: Method verifyTitle should have no parameters at org.junit.runners.model.FrameworkMethod.validatePublicVoidNoArg(FrameworkMethod.java:69) at org.junit.runners.ParentRunner.validatePublicVoidNoArgMethods(ParentRunner.java:131) at org.junit.runners.BlockJUnit4ClassRunner.validateTestMethods(BlockJUnit4ClassRun"**

XML代码：

<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd" >

<suite name="Suite1" parallel="tests" >
  <test name="fireFoxTest" >
  <parameter name="browser" value="fireFox"/>
    <classes>
       <class name="crossbrowser.VerifyTitle" />
    </classes>
  </test>

班级代码：

package testCases;

import org.junit.Test;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
import org.testng.annotations.Parameters;

import utility.ConfigReader;

public class VerifyTitle {

    WebDriver driver;
    static ConfigReader config;

    @Test
    @Parameters("browser")

    public void verifyTitle(String browserName) {
if (browserName.equalsIgnoreCase("chrome"))

        {
            config = new ConfigReader();

            System.setProperty("Webdriver.chrome.driver", config.getChromePath());

            System.out.println("========== Setup Ready =========");
        }

可能是什么原因以及如何解决？

Answer 1

问题是你混淆了JUnit和TestNG。如果您打算使用 TestNG ，那么：

删除
```
import org.junit.Test;
```
添加
```
import org.testng.annotations.Test;
```

请参阅完整示例here。

如果您打算使用 Junit ，那么

删除

import org.testng.annotations.Parameters;

添加

import org.junit.runner.RunWith;
import org.junit.runners.Parameterized;
import org.junit.runners.Parameterized.Parameter;

以这种方式注释类：

@RunWith(Parameterized.class)
public class VerifyTitle {

添加名为browserName的成员变量，并从函数中删除参数。注释该变量而不是函数：
```
@Parameter(value = "chrome")
public String browserName;

@Test
public void verifyTitle() {
```

请参阅完整示例here

Answer 2

i tried to fix the problem according the steps above but still i encountered failures.

this is what i did:

import org.junit.Test;
import org.junit.runner.RunWith;
import org.junit.runners.Parameterized;
import org.junit.runners.Parameterized.Parameter;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;

import utility.ConfigReader;

@RunWith(Parameterized.class)
public class VerifyTitle {

    WebDriver driver;
    static ConfigReader config;

    @Parameter(value = "chrome")
    public String browserName;

    @Test
    public void verifyTitle() {
if (browserName.equalsIgnoreCase("chrome"))

        {
            config = new ConfigReader();

            System.setProperty("Webdriver.chrome.driver", config.getChromePath());

            System.out.println("========== Setup Ready =========");
        }

我看到的问题：

1. import org.junit.runners.Parameterized.Parameter; ----not recognized
2. java.lang.Exception: No public static parameters method on class testCases.VerifyTitle
    at org.junit.runners.Parameterized.getParametersMethod(Parameterized.java:163)
    at org.junit.runners.Parameterized.getParametersList(Parameterized.java:149)
    at org.junit.runners.Parameterized.<init>(Parameterized.java:135)
    at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method)
    at sun.reflect.NativeConstructorAccessorImpl.newInstance(Unknown Source)
    at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(Unknown Source)

Am i missing something else?
Thanks

使用JUnit Selenium WebDriver和xml文件测试失败
