How to wait until all ajax requests are complete in Selenium IDE?

The answer turned out to be rather simple - all you have to do is check the number of active requests (selenium.browserbot.getUserWindow().$.active) with the waitForEval command, and set the value to 0 - and it all happens in the ide.

I haven't used IDE in a while. This is what I use for WebDriver. But the algorithms translate; JavaScript is JavaScript. That being said, it depends on your framework.

For Angular, I use this:

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);}

For Prototype I use:

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);}

For jQuery, I use this (you have to customize the wait for spinner logic, everybody does it differently):

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); }

In the end, solving the problem arose addition of AJAX. I'm testing it for a few days - an ingenious solution. Appendix on that at every step made selenium automatically waits for the execution of AJAX.
