Firefox driver 失败并收到无法访问的错误
Firefox driver fails and gets an unreachable error
正在使用我组装的 dart 网络应用程序进行一些测试。我按照标准 运行 使用 pub build ，然后做了一个简单的 python -m SimpleHTTPServer 来启动服务器。惊人的。可以在两种浏览器上访问 localhost:8000。
然后我进入我的 Java 应用程序进行 运行 一些 Selenium 测试。简单如 运行 应用程序。它在 Chrome 上成功，但在 Firefox 上失败。我已经针对具有不同标题的其他页面进行了测试。它工作得很好并且通过了两个测试，但是这似乎不起作用。
当代码执行时，我看到它打开两个浏览器并相应地导航。
Java代码：
@Test
public void testWithChrome(){
WebDriver driver = new ChromeDriver(DesiredCapabilities.chrome());
testSuite(driver);
}
@Test
public void testWithFirefox(){
WebDriver driver = new FirefoxDriver(DesiredCapabilities.firefox());
testSuite(driver);
}
public void testSuite(WebDriver driver){
driver.navigate().to("http://localhost:8000/web/");
Assert.assertTrue("title should start with Polymer Todo App",
driver.getTitle().startsWith("Polymer Todo App"));
System.out.printf("This is a Test: '%s'\n", driver.getTitle());
System.out.println(driver.getTitle().startsWith("Polymer Todo App"));
driver.close();
driver.quit();
}
可见还是很简单的。您还可以看到我有一些打印语句。这些打印语句显示在控制台输出中。我只是不确定为什么我会中止和 UnreachableBrowserException

为了解决这个问题，我执行了以下操作：
static Map<String, WebDriver> driverMap = new HashMap<String,WebDriver>();
@BeforeClass
public static void initDriverMap(){
driverMap.put("chrome", new ChromeDriver(DesiredCapabilities.chrome()));
driverMap.put("firefox", new FirefoxDriver(DesiredCapabilities.firefox()));
}
@AfterClass
public static void cleanUp(){
Iterator it = driverMap.entrySet().iterator();
while (it.hasNext()) {
Map.Entry<String,WebDriver> pair = (Map.Entry)it.next();
pair.getValue().close();
try {
pair.getValue().quit();
}catch(Exception e){}
}
}
@Test
public void testWithChrome(){
WebDriver driver = driverMap.get("chrome");
testSuite(driver);
}
@Test
public void testWithFirefox(){
WebDriver driver = driverMap.get("firefox");
testSuite(driver);
}
public void testSuite(WebDriver driver){
driver.navigate().to("http://localhost:8000/web/");
Assert.assertTrue("title should start with Polymer Todo App",
driver.getTitle().startsWith("Polymer Todo App"));
System.out.printf("This is a Test: '%s'\n", driver.getTitle());
System.out.println(driver.getTitle().startsWith("Polymer Todo App"));
// driver.close();
// driver.quit();
}
起初，我 运行 它没有 @AfterClass 中的 try-catch，它正确执行了所有任务，但随后退出失败。因为我没有测试退出，所以我在它周围放置了一个 try-catch 来抑制它，因为现在 Mozilla 似乎正在按需启动。
本质上，当我运行 class 进行测试时，它会首先放入测试用例驱动程序。我不想自动化测试，因为我需要测试功能。我可以稍后更新。
在 Afterclass 中，我会 运行 清理并关闭所有打开的驱动程序。有 1 个缺点，那就是所有驱动程序都保持打开状态，直到测试全部完成。虽然我不想这样做，但我不想在我的实际 testSuite 中放置一个 try-catch。
在研究了一些变体之后，我发现在给定时间点打开较少浏览器的最佳结果如下：
public void testWithChrome(){
WebDriver driver = new ChromeDriver(DesiredCapabilities.chrome());
testSuite(driver);
driver.close();
try {
driver.quit();
}catch(Exception e){
System.out.println("Driver error preventing from Quitting.");
}
}
@Test
public void testWithFirefox(){
WebDriver driver = new FirefoxDriver(DesiredCapabilities.firefox());
testSuite(driver);
driver.close();
try {
driver.quit();
}catch(Exception e){
System.out.println("Driver error preventing from Quitting.");
}
}
public void testSuite(WebDriver driver){
driver.navigate().to("http://localhost:8000/web/");
Assert.assertTrue("title should start with Polymer Todo App",
driver.getTitle().startsWith("Polymer Todo App"));
System.out.printf("This is a Test: '%s'\n", driver.getTitle());
System.out.println(driver.getTitle().startsWith("Polymer Todo App"));
}
因为我想在同一范围内关闭和退出驱动程序。这样就没有关闭浏览器的测试用例，就像它 运行 关闭整个套件然后在完成该功能后关闭。
