Selenium Framework for Beginners 29 | Selenium Waits | How to use Implicit and Explicit waits

[@Faz540]

Nice, this is by far one of the most important things to learn when writing a Selenium framework. I added this wait to my Google Search page object so that when I click the Search button, it also waits for the "About x results found" element to be visible. That way the I know the search was performed. I just need to write an assertion now to assert that at least one result was returned to properly prove the search was successful :)

[@RaghavPal]

Glad to know this Paul. Happy learning.

Thank you Raghav for all the awesome tutorials.......... Your effort is really commendable.....

Most welcome

[@dishantpatel2313]

You explain everything really well. Small suggetion when you explaining any concept please tell us pre-requisit like if we need to import any specific .jar file before using class and functions. Becuase many a times as per videos its working but when we practice in live it get failed as we have not setup .jar file. So it is better if you mention the same in your notes as well. Keep up the good work. I learnt a lot from your videos.

Hola Raghav, in official selenium website , they said "Do not mix implicit and explicit waits. ", but u said "You can set an implicit wait for entire session and Explicit wait for certain elements " the question is "can i use both in the same session of driver?" or should i apply one of them only? thanks for sharing knowledge

[@RaghavPal]

Hi Sarah, logically you can add both and I also do not see any issues in that. In face you must add an implicit wait that will work for your entire session and wherever you have a need to put an explicit wait with some condition, you can add that.

[@lex22]

Hey Raghav thank you for your helpful videos. implicitylyWait method is deprecated. Is there another way to use to wait implicityly?

[@SSK-83]

Hi Raghav, Does have any pre-requisites needed for explicit wait WebDriverWait and implicit Wait? If yes, what those are? My case always shows the Cut-Off line over the word implicit wait and WebDriverWait.

[@RaghavPal]

Hi Suyen, can check some latest examples on the web

[@SSK-83]

Hi Raghav, When I use this - WebDriverWait wait = new WebDriverWait(driver, Duration.ofSeconds(2)); wait.until(ExpectedConditions.visibilityOfElementLocated("useremail"); Showing an error - The method visibilityOfElementLocated(By) in the type ExpectedConditions is not applicable for the arguments (String) How can I solve this?

[@RaghavPal]

Hi Suyen, pls check the latest examples online in case you are using Selenium 4

[@sangshen8]

I had a question regarding implicit wait using Python. I had specified cls.driver.implicitly_wait(20) in "def setUpClass(cls)" & my test method is "def test_login(self)". The wait didn't work on the elements within the test_login method. So I changed the setup method to “setUp(self)”. Now it works. But I noticed that at the end it somehow launches another browser session. Not sure why it does that. Also, how can I make it work using setUpClass(cls)? Thanks!

[@RaghavPal]

Hi, will need to analyze your code

[@sangshen8]

@@RaghavPal Browser session doesn't close with either close() or quit(). In fact it launches another browser session. I know it sounds weird but that's exactly what is happening. When I remove this code - test_teardown(self): self.driver.quit() it doesn't launch another browser session and the existing one remains open. This issue is only for Safari. Works well on Chrome. Any idea why this is happening?

[@RaghavPal]

Try step by step debugging

[@amankul-yt]

Actually we can also throttle the network in Chrome -> Dev Tools -> Network to simulate slower connection. Checkout developers.google.com/web/tools/chrome-devtools/network/imgs/tutorial/slow3g.png . This will enable to test different page load and element visibility times and impact of waits. Just my 2 cents.

[@RaghavPal]

Thanks for this Amankul

[@varshamuppalaneni4725]

Hi Raghav, Is explicit wait a hard wait? Or does explicit wait have a polling time as well?

[@RaghavPal]

Hi Varsha, it has timeout and will continue as soon as the action is successful

[@superbbcfan]

Hello Raghav, suppose we define some element and write the code to find it using webdriver methods and locators in line 5. But if we define our implicit wait in line 10, then the implicit wait will not be applicable to the line 5 (even though we say the implicit wait is applicable to the entire webdriver session), am I right?

[@RaghavPal]

Nitish That is correct. The implicit wait is applied to all element location calls after the implicit wait is set, but not to element location calls that are made before the implicit wait is set. For example, if you have the following code: ```java // Line 1: Define an element WebElement element = driver.findElement(By.id("my-element")); // Line 10: Set the implicit wait driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS); // Line 15: Find the element again WebElement element2 = driver.findElement(By.id("my-element")); ``` The implicit wait will be applied to line 15, but not to line 1. This means that the WebDriver will wait for up to 10 seconds for the element to be found on line 15, but it will not wait for any amount of time for the element to be found on line 1. If you need to wait for an element to be found before the implicit wait is set, you can use an explicit wait. Explicit waits allow you to specify a specific condition that must be met before the WebDriver proceeds. Here is an example of how to use an explicit wait to wait for the element to be found on line 1 of the previous code example: ```java // Line 1: Define an element WebElement element = driver.findElement(By.id("my-element")); // Line 5: Wait for the element to be found WebDriverWait wait = new WebDriverWait(driver, 10); wait.until(ExpectedConditions.elementToBeClickable(element)); // Line 10: Set the implicit wait driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS); // Line 15: Find the element again WebElement element2 = driver.findElement(By.id("my-element")); ``` This code will wait for up to 10 seconds for the element to be found on line 5. If the element is not found within 10 seconds, the WebDriver will throw an exception. It is generally recommended to use explicit waits instead of implicit waits, because explicit waits give you more control over when the WebDriver waits for elements to be found.

[@superbbcfan]

@@RaghavPal Thank you for the clarification. Also, I genuinely appreciate your prompt replies to doubts in the comments and your awesome explanation.

[@kirtirajpatil4307]

hi Raghav, Can you exclude the particular webelement from the implicit wait? As once we declared the implicit wait it is apply for all the webelement. This is one of interview question i have face recently. Thanks in advance.

[@RaghavPal]

Hi Kirtiraj, you may disable implicit wait or make it 0 sec before that element line and then again enable it This can also be done in a conditional way or having a flag value to enable or disable when required

[@sidb2023]

Excellent

[@RaghavPal]

Thank you so much Siddharth

[@grvlal]

The default polling time for the implicit wait is 250 ms or 500 ms ?? Please answer?

[@RaghavPal]

Hi Gaurav, I believe its 250

[@thestonesurgeon]

Gaurav you are right default polling time is 500 ms.

[@kshipra4504]

Hi! Great content. I have one doubt...you said for implicit wait that default timeout is 250 ms in eclipse and 0 sec on your slide. Which is true?

[@RaghavPal]

Hi Kshipra, its 250 ms

[@superbbcfan]

Hello Raghav. You mentioned that implicit wait will poll every 250 msec. What does polling mean?

[@RaghavPal]

Hi Nitish, it means it will check after every 250 ms and if the condition becomes true will proceed to next step

[@superbbcfan]

@@RaghavPal Ok so if it checks and finds the element, then it doesn't need to wait for the rest of the length of time from the mentioned wait time. Am I right?

[@RaghavPal]

right

[@RaghavPal]

Hi Raju, no as far as I know

thank you so much for reply. currently I am struggling in identifying xpath of lable. //td[text()='CK_SUM'] this works good for chrome but when I tried in IE it not able to recognize the element. I am given both explicity and implicity wait and also pageload wait time. Any idea what is the problem?

[@RaghavPal]

automation on IE is not very smooth as compared to Chrome or Firefox. You can check with diff locators and xpath. If its not imp, you can run your test on other browsers.

Will you provide some folder structure for automation testing: Selenium java? Actually, I am a beginner so I am confused about what will happen if I have to test a full Web application.

[@RaghavPal]

Hi Abhishek, you can continue as per the sessions shown. Ideally we follow POM where we keep objects separately and test script in a separate folder. Then other things go in util folder, we can have config folder for any configuration files.

@@RaghavPal you mean to say all cases will be written in same Java class

[@Abhishek-jt5xe]

@@RaghavPal will you tell me about how can I make the whole project into executable file

[@RaghavPal]

Hi Abhishek, you can categorize in difference java classes as per your needs, In case there are many test cases you can create groups e.g. a LoginTest class having all tests related to login.

[@RaghavPal]

Hi Abhishek, you can generate a jar file from eclipse, but not recommended. You can use a maven project and use command line to run your maven project. Can also put it on github and can pull it on any system and run the project

And also will all test cases written in a single java class?

That will depend on your need. You can write in diff classes, however if you are going to have many test cases like in 100s, it might be too many classes in a project. You can categorize and club test cases
