TestCloud execution time in Katalon Studio

When using TestCloud in Katalon Studio, you may encounter slow test execution time. For example, opening a browser window can take a few seconds. Execution time with TestCloud in Katalon Studio is usually longer than in TestOps due to the following factors:

• TestCloud devices are hosted in several regions with multiple Internet hops that increase latency.

• Katalon Studio and Katalon Runtime Engine sequentially send Selenium commands to TestCloud using the Remote WebDriver protocol. This can increase execution time if the script or custom keywords contain many individual steps.

The following diagram compares the execution models of TestCloud: local execution, TestCloud-Katalon Studio, and TestCloud-TestOps.

The execution model of TestCloud with TestOps achieves the same network performance as in local machine, as most components are hosted in Katalon network. This model also removes the need to maintain an online machine to host Katalon Studio or Katalon Runtime Engine.

To remove latency, we recommend uploading your tests to TestOps and schedule them with TestCloud.
