"No Driver Found" message when executing mobile testing

Issue:

Facing error message when executing mobile testing:

com.kms.katalon.core.exception.StepFailedException: No driver found

Solution:

1. Make sure to set a correct directory in Appium Directory Setting:

• Go to Katalon Studio > Preferences > Katalon > Mobile

On Macbook: usr/local/lib/node_modules/appium

On Windows:  C:\npm\node_modules\appium

2. Confirm that you are using the Mobile.startApplication function in your test or test suite as the first step. If the application isn’t started, you might see that error message.

3. If you’re using a test suite, try to avoid starting and stopping the application between tests - start it once at the beginning of the suite and shut it down at the end. Repeated starting and stopping of the application can put the driver in a bad state.

4. Before running a test or test suite, check your running system processes for appium. Sometimes these processes don’t quit correctly and can interfere with future tests.
