Replace implicit wait with explicit wait (selenium webdriver & java)

Implicit wait is defined once right after the driver initialization for the driver life time, and it sets the maximum amount of time for the driver to look foe WebElement.

Explicit wait is used to wait up to the given amount of time for the WebElement to be in cretin condition, and need to be used each time you are waiting for condition to met.

You can't "replace" the implicit wait definition with explicit wait, as they are different thing and there is no condition to wait for in this point.


ExplicitWait

As per the documentation, an ExplicitWait is a code block you define, configure and implement for the WebDriver instance to wait for a certain condition to be met before proceeding for the next line of code. There are some methods that helps us to implement ExplicitWait that will wait only as long as required. WebDriverWait in combination with ExpectedConditions is one of the way ExplicitWait can be achieved.


An Example

driver.get("http://www.example.com/");
new WebDriverWait(driver, 10).until(ExpectedConditions.elementToBeClickable(By.cssSelector("element_css"))).click();

Explanation

This implementation of ExplicitWait waits up to 10 seconds before throwing a TimeoutException or if it finds the element then it will return within 0 to 10 seconds. WebDriverWait by default calls the ExpectedCondition every 500 milliseconds until it returns successfully. A successful return value for the ExpectedCondition function type is a Boolean value of true or a not-null object.


Expected Conditions

There are some frequently encountered conditions when automating Web Browsers for testing Web/Mobile applications. The Java, C# and Python bindings include those convenient methods so we don’t have to write-up an ExpectedCondition class ourselves or create our own utility package for them. Some of the Expected Conditions are:

  • alertIsPresent()
  • elementToBeClickable(locator)
  • elementToBeSelected(WebElement)
  • frameToBeAvailableAndSwitchToIt(locator)
  • invisibilityOf(element)

Here you can find about the all the methods supported by Expected Conditions.


Inducing ExplicitWait

To induce ExplicitWait, first you have to remove all the calls to implicitlyWait() in your Test Framework. Start a fresh execution and observe where you face the exception for an element attribute. The exceptions we will be facing will be either one of the follows:

  • NoSuchElementException
  • ElementNotVisibleException
  • ElementNotSelectableException

Now, we need to confirm the particular attribute of the WebElement for which we need to wait. If the WebElement in consideration is to be clicked we will consider Expected Conditions as elementToBeClickable(locator).

Element is Clickable implies Element is Displayed and Enabled.


Outro

Do not mix implicit and explicit waits. Doing so can cause unpredictable wait times. For example setting an implicit wait of 10 seconds and an explicit wait of 15 seconds, could cause a timeout to occur after 20 seconds.


once you declare implicitlyWait it will apply to your all element through out the script run. So declare it initially to prevent from script getting fail.

Now if there is element which requires explicit wait then just declare it just before to do some action or use refernce of same. explicit wait is not applied through out like implicitlyWait.

Example :-

WebElement seleniumlink;
seleniumlink= wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//input[@id='add_files_btn']")));
seleniumlink.click();
