Question

我正在使用Selenium和Selenium IDE测试一个非常重量级的Web应用程序。一切正常，直到最终提交。通常由于仍在进行中的ajax请求的数量（通常大约20个）而导致错误输出。有没有办法让selenium等待所有ajax请求完成？我试过waitForEval Value =“$ .active == 0”（如下图所示），但似乎没有做任何事

这是Selenium IDE可以实现的吗？

注意 - 我必须使用IDE，因为业务类型和我来回传递脚本。

Answer 1

答案结果相当简单 - 您只需要使用waitForEval命令检查活动请求的数量（selenium.browserbot.getUserWindow（）。$。active），并将值设置为0 - 并且这一切都发生在ide中。

Answer 2

我暂时没有使用过IDE。这就是我用于WebDriver的内容。但算法转换; JavaScript是JavaScript。话虽如此，这取决于你的框架。

对于Angular，我用这个：

public boolean waitForAngularToLoad(WebDriver driver, int waitTimeInSeconds) {

    WebDriverWait wait = new WebDriverWait(driver, waitTimeInSeconds, 2000L);

    ExpectedCondition<Boolean> libraryLoad = new ExpectedCondition<Boolean>() {

      public Boolean apply(WebDriver driver) {
        try {
          return ((Boolean)((JavascriptExecutor)driver).executeScript(
                  "return angular.element(document.body).injector().get(\'$http\').pendingRequests.length == 0;"
                  ));
        }
        catch (Exception e) {
            // Angular not found
            log.info("Not found: " + "return angular.element(document.body).injector().get(\'$http\').pendingRequests.length == 0;");
            return true;
        }
      }
    };

    // wait for browser readystate complete; it is arguable if selenium does this all the time
    ExpectedCondition<Boolean> jsLoad = new ExpectedCondition<Boolean>() {

      public Boolean apply(WebDriver driver) {
        return ((JavascriptExecutor)driver).executeScript("return document.readyState;")
        .toString().equals("complete");
      }
  };

  return wait.until(libraryLoad) && wait.until(jsLoad);

}

对于Prototype，我使用：

public boolean waitForPrototypeToLoad(WebDriver driver, int waitTimeInSeconds) {

    WebDriverWait wait = new WebDriverWait(driver, waitTimeInSeconds, 2000L);

    // wait for jQuery to load
    ExpectedCondition<Boolean> libraryLoad = new ExpectedCondition<Boolean>() {

      public Boolean apply(WebDriver driver) {
        try {
          return ((Boolean)((JavascriptExecutor)driver).executeScript("return Ajax.activeRequestCount == 0;"));
        }
        catch (Exception e) {
            // Prototype  not found
            log.info("Not found: " + "return Ajax.activeRequestCount == 0;");
            return true;
        }
      }
    };

    // wait for browser readystate complete; it is arguable if selenium does this all the time
    ExpectedCondition<Boolean> jsLoad = new ExpectedCondition<Boolean>() {

      public Boolean apply(WebDriver driver) {
        return ((JavascriptExecutor)driver).executeScript("return document.readyState;")
        .toString().equals("complete");
      }
  };

  return wait.until(libraryLoad) && wait.until(jsLoad);

}

对于jQuery，我使用它（你必须自定义等待微调器逻辑，每个人都做不同的事情）：

public boolean waitForJSandJQueryToLoad(WebDriver driver, long waitTimeInSeconds) {

    WebDriverWait wait = new WebDriverWait(driver, waitTimeInSeconds, 2000L);

    /*
     * If you are curious about what follows see:
     *  http://selenium.googlecode.com/git/docs/api/java/org/openqa/selenium/support/ui/ExpectedCondition.html
     * 
     * We are creating an anonymous class that inherits from ExpectedCondition and then implements interface
     * method apply(...)
     */
    ExpectedCondition<Boolean> libraryLoad = new ExpectedCondition<Boolean>() {

      public Boolean apply(WebDriver driver) {
        boolean isAjaxFinished = false;
        boolean isLoaderSpinning = false;
        boolean isPageLoadComplete = false;
        try {
          isAjaxFinished = ((Boolean)((JavascriptExecutor)driver).executeScript("return jQuery.active == 0;"));
        } catch (Exception e) {
            // no Javascript library not found
            isAjaxFinished = true;
        }
        try { // Check your page, not everyone uses class=spinner
            // Reduce implicit wait time for spinner
            driver.manage().timeouts().implicitlyWait(10L, TimeUnit.SECONDS);

//              isLoaderSpinning = driver.findElement(By.className("spinner")).isDisplayed(); // This is the default
            // Next was modified for GoComics
            isLoaderSpinning = driver.findElement(By.cssSelector("#progress_throbber > ul > li:nth-child(1) > img[alt='spinner']")).isDisplayed();

            if (isLoaderSpinning)
                log.info("jquery loader is spinning");
        } catch (Exception f) {
            // no loading spinner found
            isLoaderSpinning = false;
        } finally { // Restore implicit wait time to default
            driver.manage().timeouts().implicitlyWait(new DriverFactory().getImplicitWait(), TimeUnit.SECONDS);
        }
        isPageLoadComplete = ((JavascriptExecutor)driver).executeScript("return document.readyState;")
                .toString().equals("complete");
        if (!(isAjaxFinished & !(isLoaderSpinning) & isPageLoadComplete))
            log.info(isAjaxFinished + ", " + !(isLoaderSpinning) +", " + isPageLoadComplete);

        return isAjaxFinished & !(isLoaderSpinning) & isPageLoadComplete;
      }
    }; // Terminates statement started by ExpectedCondition<Boolean> libraryLoad = ...

  return wait.until(libraryLoad); 
}

最后，解决问题的原因是增加了AJAX。我正在测试它几天 - 一个巧妙的解决方案。关于每一步的附录，selenium会自动等待AJAX的执行。
