Node.js allows for client-side JavaScript execution on BrowserStack

After developing a tool to automate visual regression within an E2E test suite, I have encountered a challenge when trying to measure visual regression with autoplaying HTML5 videos. Due to the dynamic nature of videos and the variability in Browserstack's server speed, it is difficult to capture reliable screenshots for comparison purposes. This often results in a significant visual difference of up to 90% during the build process.

One potential solution could involve directing the visual regression tool to a specific URL without videos or in testing mode. However, I am also interested in exploring the possibility of executing JavaScript directly on the active browser session in BrowserStack to control the playback of HTML5 videos and set them to a fixed frame for more accurate visual regression testing.

I am curious if there is a similar function to camme's version of webdriverjs' execute function available in browserstack-webdriver, as this capability would be beneficial for handling different scenarios where specific JavaScript execution is necessary for optimal visual regression testing.

Answer №1

I have managed to overcome this obstacle by closely examining the source code of the node module. To assist others facing the same challenge, you can employ the following command:

driver.executeScript('alert("bar")');

In dealing with challenges related to video and visual regression, I have opted for using a query string in the URL as a more dependable method to manipulate dynamic aspects of a website. Resorting to executing JavaScript within the executeScript function not only felt unclean but also brings along its own set of browser compatibility issues, thereby complicating matters especially for larger teams.
