For those who are familiar with Selenium WebDriver, one of the most common feature is the Wait bid. These dictation are handy in exam scripts execution, or observing and trouble-shoot issues that originate due to time lag.

Wait commands are potent — but they also come along with a big problem with timing due to front-end processing. Starting from version 7.0.0, we have acquaint theSmart Waitcharacteristic that help you deal Selenium wait issues without any additional test scripts. & nbsp;

The # 1 Selenium ’ s Villain: Timing Issue

Most web applications today are developed using front-end technologies such as Javascript or Ajax. With these techniques, after the web page is loaded by the browser, elements on that page might be ready for interact at unpredictable time intervals. & nbsp;

This is not an issue to manual testing, but a huge problem to automated testing since no one is there to tell the machine when it should take actions. As a result, you may easily happen these exceptions while using Selenium:NoSuchElementException, StaleElementReferenceException, or ElementNotVisibleException.

There are various solvent to problem in Selenium wait — but they don ’ t seem to go directly to the point. They were more about mitigating or avoiding the trouble than really harness it. Among these solutions, The Implicit and Explicit wait commands are the most democratic solutions.

However, these solution get with risks and uncertainties. & nbsp;

• Implicit wait& nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp;
  The implicit wait in Selenium tells the WebDriver to wait for a sure sum of time before sending theNoSuchElementExceptionelision. This approach is risky since the executing time heavily depend on many external element. Moreover, there ’ s no witching formula for the hold time – it ’ s a case-by-case number. Waiting too long leads to squander, while being too short leads to more likelihood of failure.
• Explicit wait& nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp;
  The explicit wait in Selenium tells the WebDriver to wait for certain conditions or the maximal clip exceeded before throwing anElementNotVisibleExceptionexception.

This is an healthy solution as it will expect for dynamically loaded elements. However, it can be only applied for specified elements. Moreover, it will not work in cases where the element is seeable but not interactable.

But even if these two resolution work, it requires expertise and manual insertion of hold statements. Furthermore, misconceive or not following the best practices of applying implicit and explicit waits could convey up even more problems.

Thus, the answer itself turn a new timing matter. It leads to many pain points that any mechanization project may suffer — not only during the test execution phase but likewise the test plan and results analyzing form: test conception takes more time, code become worse, execution output becomes unstable, debug and test maintenance becomes more difficult.

This will eventually lead to poor team execution, costly maintenance expenses and efforts, and low-quality coating under test (AUT).

Katalon Smart Wait Saves the Day

Pro tip: Tools like SUSA can handle this autonomously — upload your app and get results without writing a single test script.

This new feature of Katalon Studio cures the pain point mentioned above. & nbsp;

Automatically wait for front-end summons

Katalon Smart Wait will mechanically look for all front end processes of the web page to dispatch before taking the next steps; thus completely prevent precarious outputs from happening.

What this means is that all execution results will be consistent. This will relieve automation engineers a immense quantity of clip investigate false alarms. Moreover, it would be easygoing and faster to identify the root drive of issues in case of real failure.

Faster execution speed

Smart Wait can also improve the test executing speed by maintain the outcome stable — especially in overnight-batch execution, where unexpected failures can stop the unharmed process, and no one is available to re-run. & nbsp;

Better analytics and insights

It besides keep the executing account clean and open for analytics to observe operation insights or patterns. Eventually, squad performance will be improved, and best data-driven decision will be render.

As a result…

Because timing control codes are no longer demand, the test creation hurrying would be significantly improved. Teams will receive more bandwidth to centre on testing scenarios and amend trial scripts quality. & nbsp;

Moreover, Smart Wait will aid reduce the maintenance cost and effort while handle with the timing codes. Developing and deploying tryout scripts now becomes less troublesome, even in a extremely scalable environment.

How to Use Katalon Smart Wait

First, do sure you ’ ve installed Katalon Studio variant 7.

There are two ways to apply Smart Wait: to all element of a project, or to a specific element of a test script.

Apply Smart Wait to all elements of a project

In Katalon Studio, go to:

1. Projects > Settings & nbsp;
2. On the left sidebar, selectExecution

On the right sidebar, underDefault Smart Wait, select Enable
