how to measure response time for both loading and search time for a website ? selenium

Question

I need to measure response time for website using Selenium and Selenide.

• Response time of a website:

  I mean the loading time, I see that there is method to take difference between time before and after open website.

  But this way, will measure the client loading time, will it depend on the used client? What is the best way for do that?

• long startTime = System.currentTimeMillis();
  
  driver.get("http://zyxware.com");
  new WebDriverWait(driver, 10).until(ExpectedConditions.presenceOfElementLocated(By.id("Calculate")));
  
  long endTime = System.currentTimeMillis();
  long totalTime = endTime - startTime;
  
  System.out.println("Total Page Load Time: " + totalTime + "milliseconds");
  

or this?

driver.get("url");
        WebElement ele = $(By.tagName("body"));
        // get the  page load time
        Long loadtime = (Long)((JavascriptExecutor)driver).executeScript(
            "return performance.timing.loadEventEnd - performance.timing.navigationStart;");        
        System.out.println(loadtime);

and last way the following:

StopWatch pageLoad = new StopWatch();
            pageLoad.start();
            //Open your web app (In my case, I opened facebook)
            driver.get("url");
            // Wait for the required any element (I am waiting for Login button in fb)
            WebDriverWait wait = new WebDriverWait(driver, 10);
            wait.until(ExpectedConditions.presenceOfElementLocated(By.tagName("body")));

            pageLoad.stop();
            //Get the time
            long pageLoadTime_ms = pageLoad.getTime();
            long pageLoadTime_Seconds = pageLoadTime_ms / 1000;
            System.out.println("Total Page Load Time: " + pageLoadTime_ms + " milliseconds");

• If I have a search button for the same website, if I need to measure the search time, how to do it? Is it as same as the above way?

Answer 1

You can use selenium web driver to gather the timing data about your web page. Just do this:

from selenium import webdriver

source = "http://www.example.com/"
driver = webdriver.Chrome()
driver.get(source)

navigationStart = driver.execute_script("return window.performance.timing.navigationStart")
responseStart = driver.execute_script("return window.performance.timing.responseStart")
domComplete = driver.execute_script("return window.performance.timing.domComplete")

backendPerformance = responseStart - navigationStart
frontendPerformance = domComplete - responseStart

print "Back End: %s" % backendPerformance
print "Front End: %s" % frontendPerformance

driver.quit()

Answer 2

You can get the timing-related performance information for a given page with the performance.timing API:

// launch the browser
WebDriver driver = new FirefoxDriver();

// visit a page
driver.get("http://stackoverflow.com");

// get the  page load time
Long loadtime = (Long)((JavascriptExecutor)driver).executeScript(
    "return performance.timing.loadEventEnd - performance.timing.navigationStart;");

Selenium doesn't provide a better way to do this. The way you are using it is the best way possible as far as I know. For the search method you can use the same way as you used for the page loading. Except you'd be doing some different actions between the start and stop time.

Also take a look at this question as I believe it answers your question. How can we get exact time to load a page using Selenium WebDriver?
