Synchronization issue in Selenium

What is Synchronization in Selenium?

When an action is to occur, it is expected that all components involved work together seamlessly. This collaborative process among components is referred to as synchronization. In Selenium, synchronization ensures that the code and applications execute in more efficiently to carry out the desired operation....

How to achieve synchronization in the Selenium Web driver?

Managing synchronization in Selenium is vital to ensure alignment between our driver and the browser when engaging with web elements that might load at varying intervals. There exist multiple methods to adeptly address synchronization....

Thread.Sleep

The Java Thread.sleep() function lets you temporarily pause the current thread’s execution for a specified duration in milliseconds. You can’t use a negative value as the argument for milliseconds; if you do, it will result in an IllegalArgumentException being thrown....

Explicit Waits

An explicit wait provides greater flexibility by enabling us to pause test execution until a particular condition is satisfied. This condition, such as the existence or non-existence of an element, can be defined using the ExpectedConditions class. If the condition isn’t met within the designated timeframe, an exception will be raised. Implicit waits are convenient for basic scenarios, instructing the WebDriver to wait for a certain duration when locating elements. However, they may lead to unnecessary waiting if elements appear sooner than expected. In contrast, explicit waits offer better control by pausing the script until specific conditions are met....

Implicit Wait

An implicit wait instructs the Web Driver to patiently search the DOM for a specified duration when attempting to locate an element or elements if they’re not readily accessible. By default, this duration is set to 0. Once configured, the implicit wait remains effective throughout the lifespan of the Web Driver object instance until it’s modified again....

Fluent Wait

Fluent Wait in Selenium sets the maximum duration for the Selenium WebDriver to wait until a specific condition (such as a web element) becomes visible. It also specifies how often WebDriver will check for the condition before raising an ‘ElementNotVisibleException‘....

Conclusion

In Selenium, making sure that the timing of script execution aligns with how the application behaves is important. It’s like ensuring that all the different parts of your script work together smoothly to do what you want them to do. Through various synchronization methods like Thread.sleep(), explicit waits, implicit waits, and Fluent Wait, testers can manage the coordination between the WebDriver and the browser, particularly when dealing with dynamically loading web elements. By prioritizing synchronization management, testers can enhance the reliability and robustness of their Selenium test suites, ultimately ensuring accurate and dependable results in automated testing endeavors....
