Question

我正在使用PhantomJs驱动程序进行无头测试，我正处于异常

之下

示例代码：

import static org.testng.Assert.assertEquals;
import org.openqa.selenium.Alert;
import org.openqa.selenium.By;
import org.openqa.selenium.Capabilities;
import org.openqa.selenium.NoAlertPresentException;
import org.openqa.selenium.UnexpectedAlertBehaviour;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.phantomjs.PhantomJSDriver;
import org.openqa.selenium.remote.CapabilityType;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.testng.annotations.AfterMethod;
import org.testng.annotations.BeforeMethod;
import org.testng.annotations.Test;



public class TestLogin {    
WebDriver d;
@BeforeMethod
    public void launh_Browser() {
System.setProperty("phantomjs.binary.path", "D:\\Selenium\\driver\\phantomjs-2.1.1-windows\\bin\\phantomjs.exe");
         Capabilities caps = new DesiredCapabilities();
         ((DesiredCapabilities) caps).setJavascriptEnabled(true);                
         ((DesiredCapabilities) caps).setCapability("takesScreenshot", true);     
         d=new PhantomJSDriver(caps);
    }
    @Test
    public void guru_banking_login_excel() throws Exception {
        d.get("http://www.demo.guru99.com/V4/");
        d.findElement(By.name("uid")).sendKeys("TestUser");
        d.findElement(By.name("password")).sendKeys("testpwd");
        d.findElement(By.name("btnLogin")).click();
        try{ 
            Alert alt = d.switchTo().alert();
            String actualBoxMsg = alt.getText(); // get content of the Alter Message
            assertEquals(actualBoxMsg,"User or Password is not valid");
            alt.accept();          
        }
        catch (NoAlertPresentException Ex){ 
            String hometitle=d.getTitle();
            assertEquals(hometitle,"Guru99 Bank Manager HomePage");
  }   
d.quit
}

观察到错误：

 Exception : org.openqa.selenium.UnsupportedCommandException: Invalid Command Method - {"headers":{"Accept-Encoding":"gzip,deflate","Cache-Control":"no-cache","Connection":"Keep-Alive","

我正在尝试使用phantomjs作为驱动程序来处理弹出窗口请帮助这.........

先谢谢.. !!!!

你必须在代码中处理很多要点：

在您提及 PhantomJS 时使用 System.setProperty 时，请使用以下代码行：

File src = new File("C:\\Utility\\phantomjs-2.1.1-windows\\bin\\phantomjs.exe");
System.setProperty("phantomjs.binary.path", src.getAbsolutePath());

DesiredCapabilities 对象类型必须仅参考 DesiredCapabilities 类启动。所以改为：
```
DesiredCapabilities caps = new DesiredCapabilities();
```

使用 assertEquals 时，请使用 Assert.assertEquals ，如下所示：

Assert.assertEquals(actualBoxMsg,"User or Password is not valid");
//
Assert.assertEquals(hometitle,"Guru99 Bank Manager HomePage");

当您使用 TestNG 时，对于 Assert ，请使用 org.testng.Assert; 而不是 static org.testng.Assert.assertEquals; 作为导入：
```
import org.testng.Assert;
```
您需要在单独的 d.quit() 功能中包含 TestNG Annotated 一行，如下所示：
```
    @AfterMethod
    public void tearDown() {
        d.quit();
    }
```

以下是您自己的代码块，可以成功执行：

package headlessBrowserTesting;

import java.io.File;

import org.openqa.selenium.Alert;
import org.openqa.selenium.By;
import org.openqa.selenium.NoAlertPresentException;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.phantomjs.PhantomJSDriver;
import org.openqa.selenium.remote.DesiredCapabilities;
import org.testng.Assert;
import org.testng.annotations.AfterMethod;
import org.testng.annotations.BeforeMethod;
import org.testng.annotations.Test;

public class PhantomJS_webdriver_binary 
{

    WebDriver d;

    @BeforeMethod
    public void launh_Browser() {
        File src = new File("C:\\Utility\\phantomjs-2.1.1-windows\\bin\\phantomjs.exe");
        System.setProperty("phantomjs.binary.path", src.getAbsolutePath());
        DesiredCapabilities caps = new DesiredCapabilities();
        ((DesiredCapabilities) caps).setJavascriptEnabled(true);                
        ((DesiredCapabilities) caps).setCapability("takesScreenshot", true);     
        d=new PhantomJSDriver(caps);
      }

    @Test
    public void guru_banking_login_excel() throws Exception {
        d.get("http://www.demo.guru99.com/V4/");
        d.findElement(By.name("uid")).sendKeys("TestUser");
        d.findElement(By.name("password")).sendKeys("testpwd");
        d.findElement(By.name("btnLogin")).click();
        try{ 
            Alert alt = d.switchTo().alert();
            String actualBoxMsg = alt.getText();
            Assert.assertEquals(actualBoxMsg,"User or Password is not valid");
            alt.accept();          
        }
        catch (NoAlertPresentException Ex){ 
            String hometitle=d.getTitle();
            Assert.assertEquals(hometitle,"Guru99 Bank Manager HomePage");
        }  
    }

    @AfterMethod
    public void tearDown() {
        d.quit();
    }

}
