Difference Between Implicit and Explicit waits in Selenium WebDriver

Difference Between Implicit and Explicit waits in Selenium WebDriver

Implicit Wait 

Implicit Wait is basically the internal timeout for the WebDriver for WebElement we are searching to be available. In this case, we are telling WebDriver that it should wait for certain timeout in case of specified element not available on the UI (DOM). Implicit wait is set to all the WebElement we are using in our script. It will keep on searching for the element again and again for certain time period and if it is not found at last then it throws ‘NoSuchElementException’. The default implicit timeout is set to zero.

Explicit Wait 

In Explicit Wait, we write certain type of code which is used like wait and used as per our convenience. It reaches its timeout period until certain condition is satisfied. It is a custom kind of code for particular WebElement for waiting for particular timeout. Explicit Wait is intelligent kind of wait which provide us better option that Implicit Wait. But Explicit Wait can be applied for particular specified elements.

There are many classes by WebDriver like ‘WebDriverWait’, ‘ExpectedCondition’ which are used for implementing Explicit wait.

These days for implementing this we frequently use ‘Thread.Sleeep()’ in our code, which wait exactly for the same time period we provide in brackets. But this is not the good idea to implement Explicit wait.
