How to know the exact time to load a page using Selenium WebDriver

Question

We use Thread.sleep, implicitlyWait and WebDriverWait

but How can we find the exact time to load a page using Selenium WebDriver?

Answer 1

Normally WebDriver should return control to your code only after the page has loaded completely.

So the following Selenium Java code might help you to find the time for a page load -

long start = System.currentTimeMillis();

driver.get("Some url");

long finish = System.currentTimeMillis();
long totalTime = finish - start; 
System.out.println("Total Time for page load - "+totalTime); 

If this does not work then you will have to wait until some element is displayed on the page -

 long start = System.currentTimeMillis();

driver.get("Some url");

WebElement ele = driver.findElement(By.id("ID of some element on the page which will load"));
long finish = System.currentTimeMillis();
long totalTime = finish - start; 
System.out.println("Total Time for page load - "+totalTime); 

Answer 2

long start = System.currentTimeMillis();

driver.get("Some url");

long finish = System.currentTimeMillis();
long totalTime = finish - start;
