web自动化测试(java)---测试过程中遇到的错误合集

摸索测试，不管是安装、调测第一个用例都会遇到各种各样的问题，或是自己的问题或是程序本身设置问题

只有把所有问题记录下来，才对得起自己的经历

1、设置firefox的执行文件错误

Exception in thread "main" org.openqa.selenium.WebDriverException: Cannot find firefox binary in PATH. Make sure firefox is installed. OS appears to be: VISTA
Build info: version: '2.44.0', revision: '76d78cf', time: '2014-10-23 20:03:00'
System info: host: 'YangYuchun-PC', ip: '192.168.202.1', os.name: 'Windows 7', os.arch: 'x86', os.version: '6.1', java.version: '1.8.0_171'
Driver info: driver.version: FirefoxDriver
	at org.openqa.selenium.firefox.internal.Executable.<init>(Executable.java:72)
	at org.openqa.selenium.firefox.FirefoxBinary.<init>(FirefoxBinary.java:59)
	at org.openqa.selenium.firefox.FirefoxBinary.<init>(FirefoxBinary.java:55)
	at org.openqa.selenium.firefox.FirefoxDriver.<init>(FirefoxDriver.java:95)
	at seleniumTest.FirstSelenium.main(FirstSelenium.java:9)

默认情况下firefox安装路径在c盘不会出现这个问题，如果非C盘或者非默认安装，则需要指定执行文件所在目录，如下：

package seleniumTest;
import java.util.concurrent.TimeUnit;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;

public class FirstSelenium {
	public static void main(String args[]){
		System.setProperty("webdriver.firefox.bin", "D:\\Program Files\\Mozilla Firefox\\firefox.exe");
		WebDriver driver = new FirefoxDriver();
		driver.manage().window().maximize();
		driver.manage().timeouts().implicitlyWait(8, TimeUnit.SECONDS);
		driver.get("http://www.baidu.com");

		driver.quit();
	}
}

　　

2、selenium版本不配套问题

org.openqa.selenium.firefox.NotConnectedException: Unable to connect to host 127.0.0.1 on port 7055 after 45000 ms. Firefox console output:

之前使用python测试时，firefox上selenium版本为3.0.2.0（在菜单-附件组件中查看）

所以需要安装3.0.2.0或者以上版本的java selenium的jar包才可以。重新下载selenium的jar包并重新导入
