Best Practices with Playwright automation

If you are writing an automation script first time with a playwright then you must know the best practices. This will help you to have an expandable framework, fewer failures, and good readability of the code. I have been writing playwright scripts for almost one year and also we have playwright documentation for best practices. So I will put most of from combining the both. 

Best Practices with Playwright Automation -

I have created a video tutorial on the same with the code demo, please go through the below video and subscribe to our YouTube channel.

•  Page Object Model 
•  Locators - have a separate constructor to add the locators, so if you need to change it you need to change it at only one place.
• URLs - Also having a separate variable to store URLs will help, in case URL changes in the future 
• Methods - Have a proper page object model that separates the methods from the script so you don't need to write the same code everywhere. 
  
  
• Locators
• Avoid static Xpaths
• Avoid using class names in locators, if possible use data-testIds or the IDs or texts which won't change. 
• Use locators instead of selectors - Don't write a script on the selectors-like page.click('locator') instead write like this page.locator('locator').click();
• Use double quotes in locators to find the exact element like page.getByText("Submit"). (Watch the full YouTube video for more details).
• Assertions
• Assert only if required
• Use of Soft Assertions - soft assertions are underused. It should be used more to know if something fails and also rest of the script gets executed wherever needed. 
• Use of await
• Only run tests that are stable! - Include only a stable tests suite to execute in CI/CD or Daily runs that will give you more confidence. 
• Tests should not be dependent on each other.
