In this tutorial, you will learn about Implicitly Wait and Explicit Wait in Selenium WebDriver. How Synchronization works in WebDriver.
======================================================
Implicit Wait:
•During Implicit wait if the Web Driver cannot find it immediately because of its availability, it will keep polling the DOM to get the element.
•If the element is not available within the specified Time an NoSuchElementException will be raised.
•The default setting is zero.
•Once we set a time, the Web Driver waits for the period of the WebDriver object instance.
======================================================
Explicit Wait:
•There can be instance when a particular element takes more than a minute to load.
•In that case you definitely not like to set a huge time to Implicit wait, as if you do this your browser will going to wait for the same time for every element.
•To avoid that situation you can simply put a separate time on the required element only.
•By following this your browser implicit wait time would be short for every element and it would be large for specific element.

the way you explain how to read a line of code, makes my all doubt clear! i was using implicit wait in 2 classes multiple times as i was thinking, its applicable within a block only! so i was using it in each try catch block and each methods, each if else block and in each classes!

If we have a implicit wait of 20 sec for firstname, and selenium is finding it in 5 secs, so next 15 secs is ignored, then again when we come across explicit wait of 10 secs, what will be the scenario, as the element is already found within the span of implicit wait, so will the entire time of explicit wait be skipped?

So the only differences between explicit and implicit waits 1) we can change time outs for different elements in explicit where as in implicit we cant 2) implicit wait is written once and it's applicable for all the elements and where as for explicit wait we need to write wait for every element Apart from this if any other differences pls let me know

One question ...if the element is not yet loaded..and as Yu are trying findelement before explicit wait ..it would simply throw nosuchelement exception...in your case FB is loading faster that's why you are not getting the exeption... Instead of passing webelement you should pass By and then findelement inside until...

If there is a implicit wait with 5 sec, and also there is 10 sec for explicit wait for a particular element, now if the element got found in 6 sec, it will move to the next code/step... Will driver wait for another 9 sec or move forward? If not then how this is a disadvantage to use explicit wait and implicit wait together to achieve 100% synchronization?

Hi Naveen, my doubt is, if we give implicit wait for 20 sec or 100 sec, does it make any difference if elements are loaded with in 2 sec or 3 sec, as it ignores rest of the seconds. Will it affect the performance if both implicit and explicit are given and the element is loaded within 2 to 3 sec.

@gayathri77 2 жыл бұрын

Just thought of answering your question. All timeouts in Selenium are dynamic waits. once the element is found or an expected condition is satisfied, it moves on to the next instruction.

@konarkism 3 жыл бұрын

Why nobody is asking basic difference between these two waits. I'm asking in general and will really appreciate the correct and well explained answer. If I'm using implicit wait and let's say I'm giving 1000 seconds of time.. why would anyone even need explicit wait , because all the expected conditions will ofcoursed be met by this huge amount of time.. and since implicit wait is dynamic wait it will ignore rest of time if elements appear before that time. Why even explicit wait was introduced in selenium??

@konarkism 3 жыл бұрын

Correct me if I'm wrong but I think polling time plays a key factor here that is 500 ms. so implicit wait waits for atleast 500 ms for each elements in the script.thus it makes execution comparatively slower.

Implicit will wait till amount of secs you have given even if the element is visible or loaded in less time...but in case of explicitly wait it LL not wait till the given amount sec...it LL start next line as soon as the element is visible.

@@deepankarish No that's not correct.. implicit wait is also dynamic wait, it will ignore rest of time if element appears before and move on to next step.

if any webpage has 50 webelements then for each webelement implict wait(suppose 10 sec provided) will be applied and total wait time will be 50 *10=500 second.

@ramkumar2704 3 жыл бұрын

Theoretically yes..but it could not happen mostly of tym... 😂 In detail manner - at a particular time selenium/java handle just single line of execution. So if we work with 1st Element, it wait for untill elements as appear/intractable upto 10 sec. On 11th sec also 1st elements is not appear/intractable,then it through the error message on 11th sec itself and execution will stop... No need to wait upto 500 sec. We have to wait until 500 sec for below scenario only If 1st element appear at exactly 10th sec. 2nd element appear at exactly 20th sec. 3rd elements appear at exactly 30th sec........ And so on 50th elements appear at exactly 500th sec. I'm sure it won't be happen for most of cases.

Another good way to ensure proper page load is through JavaScriptExecutor public static void waitTillPageLoaded() { JavascriptExecutor jse = (JavascriptExecutor) driver; String status = "in-progress"; while (!status.equals("complete")) { try { Thread.sleep(6000); } catch (InterruptedException e) { e.printStackTrace(); } status = (String) jse.executeScript("return document.readyState"); if (status.equalsIgnoreCase("complete")) break; }
