MicrosoftWebDriver 16299, 15063 doesn't work when I minimise Edge browser window

Question

When I execute tests using MicrosoftWebDriver for Edge all works fine, but when I minimise the window all tests become failed. Does Edge or MicrosoftWebDriver have any options to avoid that behavior?

Answer 1

As you have been trying to minimise the Browser Window while your Test Execution is In Progress it will be against all the Best Practices. At this point it is worth to mention that as Selenium mocks the User Actions hence Selenium needs Browser focus. If the focus is lost Selenium won't be able to execute the lines of code. Consider the following steps while your Test Execution :

• Browser Maximize : While you execute your tests always keep the Web Browser maximized so majority of the elements are within the Viewport

• As per best practices, you should try to execute your Test Scripts / Automation Framework in an isolated Test Environment away from Manual Intervention with all the required Software and Hardware configurations and setup.

• You also have an option to use Google Chrome or Mozilla Firefox in Headless version.

  For Firefox you can find a detailed discussion in How to make firefox headless programatically in Selenium with python?

  For Chrome you can find a detailed discussion in selenium.common.exceptions.WebDriverException: Message: 'chromedriver' executable needs to be in PATH error with Headless Chrome
