【问题标题】:Why my Selenium test code run successfully in single-step but failed when using Run?为什么我的 Selenium 测试代码单步运行成功,但使用 Run 时失败?

【问题描述】:

我有一些使用 Firefox 驱动程序进行自动 UI 测试的 Selenium 代码。我将它们绑定到一个测试套件中并有序地运行它们。但它在 driver.switchTo().frame() 调用上失败并抛出 org.openqa.selenium.NoSuchFrameException: Unable to locate frame,完整的错误消息是如下:

org.openqa.selenium.NoSuchFrameException: Unable to locate frame: OpenNewPKFD
Command duration or timeout: 3.07 seconds
Build info: version: '2.43.1', revision: '5163bceef1bc36d43f3dc0b83c88998168a363a0', time: '2014-09-10 09:43:55'
System info: host: 'H3000-0254', ip: '169.254.169.127', os.name: 'Windows Vista', os.arch: 'x86', os.version: '6.1', java.version: '1.6.0_13'
Session ID: 4fcea4bb-880c-4725-bdf1-cda4b5a03553
Driver info: org.openqa.selenium.firefox.FirefoxDriver
Capabilities [{platform=WINDOWS, acceptSslCerts=true, javascriptEnabled=true, browserName=firefox, rotatable=false, locationContextEnabled=true, version=32.0.3, cssSelectorsEnabled=true, databaseEnabled=true, handlesAlerts=true, nativeEvents=true, webStorageEnabled=true, applicationCacheEnabled=true, takesScreenshot=true}]

奇怪的是,如果我在单步模式下运行它,抛出异常的代码行会正常工作。不会发生错误。所以我怀疑有些东西与时间或速度有关,但我根本不知道它是什么。

那么你能给我一些建议来解决这个问题吗?

已更新下面是我项目的 pom.xml:

【问题讨论】:

  • 您如何找到&lt;iframe&gt; 元素?您是否使用 ExpectedCondition 来确保在您尝试切换到 DOM 时将其加载到 DOM 中?
  • @MarkRowlands 好像没有,你能给我一些关于这个的教程或示例链接吗?
  • 看看文档,selenium.googlecode.com/git/docs/api/java/org/openqa/selenium/…,下面是一个简单的例子。

【解决方案1】:

要使用 ExpectedConditions,请确保您已将它们导入到您的项目中

org.openqa.selenium.support.ui.ExpectedConditions

Webdriver driver = new FirefoxDriver();
//to wait for an element you need a webdriverWait object
WebDriverWait wait = new WebDriverWait(driver, 15);

element = wait.until(ExpectedConditions.presenseOfElementLocated(By.ID("your_id"));

对于你的问题,我想像这样:

frameToSwitchTo = wait.until(ExpectedConditions.presenseOfElementLocated(By.ID("OpenNewPKFD"));
driver.switchTo().frame(frameToSwitchTo);
