"WebDriverException: Cannot find firefox binary in PATH."的解决方法
最近在学习webdriver,顺便把遇到的问题记在这里,以便日后查阅,并分享给遇到相同问题的人。
问题:运行seleniumhq.org网站上的例子。
import org.openqa.selenium.By; import org.openqa.selenium.WebDriver; import org.openqa.selenium.WebElement; import org.openqa.selenium.firefox.FirefoxDriver; import org.openqa.selenium.support.ui.ExpectedCondition; import org.openqa.selenium.support.ui.WebDriverWait; public class Selenium2Example { public static void main(String[] args) { // Create a new instance of the Firefox driver // Notice that the remainder of the code relies on the interface, // not the implementation. WebDriver driver = new FirefoxDriver(); // And now use this to visit Google driver.get(""); // Alternatively the same thing can be done like this // driver.navigate().to(""); // Find the text input element by its name WebElement element = driver.findElement(By.name("q")); // Enter something to search for element.sendKeys("Cheese!"); // Now submit the form. WebDriver will find the form for us from the element element.submit(); // Check the title of the page System.out.println("Page title is: " + driver.getTitle()); // Google's search is rendered dynamically with JavaScript. // Wait for the page to load, timeout after 10 seconds (new WebDriverWait(driver, 10)).until(new ExpectedCondition<Boolean>() { public Boolean apply(WebDriver d) { return d.getTitle().toLowerCase().startsWith("cheese!"); } }); // Should see: "cheese! - Google Search" System.out.println("Page title is: " + driver.getTitle()); //Close the browser driver.quit(); } }
报如下错误
Exception in thread "main" org.openqa.selenium.WebDriverException: Cannot find firefox binary in PATH. Make sure firefox is installed. OS appears to be: XP
Build info: version: '2.18.0', revision: '15704', time: '2012-01-27 17:37:17'
System info: os.name: 'Windows XP', os.arch: 'x86', os.version: '5.1', java.version: '1.6.0_23'
看这个报错应该是firefox安装路径不是默认路径。
解决方法:方法1、最简单的重新安装firefox到默认路径。哈哈
方法2、直接用System.setPropert方法设置webdriver.firefox.bin的值,如
System.setProperty("webdriver.firefox.bin","D:\\Program Files\\Mozilla Firefox\\firefox.exe");
方法3、 用FirefoxBinary类和public FirefoxDriver(FirefoxBinary binary, FirefoxProfile profile)这个构造方法,直接上代码
File pathToFirefoxBinary = new File("D:\\Program Files\\Mozilla Firefox\\firefox.exe"); FirefoxBinary firefoxbin = new FirefoxBinary(pathToFirefoxBinary); WebDriver driver = new FirefoxDriver(firefoxbin,null);//这里使用这个构造方法。
应该还可以在环境变量里面设置firefox的路径也可以,有兴趣的可以试一下。
注:有人可能会不知道webdriver.firefox.bin,可以看一下源码,其中
org.openqa.selenium.firefox.internal.Executable.locateFirefoxBinaryFromSystemProperty()
方法第一句
String binaryName = System.getProperty("webdriver.firefox.bin");
说明默认的时候取的就是这个值,重新设置一下。
