Make Cypress Videos Look Old School

Recently, we introduced a trial feature called experimentalRunEvents [https://on.cypress.io/experimental] that simplifies running Node code before or after executing a spec file. Inside your plugin file [https://on.cypress.io/writing-and-organizing-tests#Plugin-files] you can add event hooks to perform operations that need OS access.

Generate High-Resolution Videos and Screenshots

This blog post shows how to increase the resolution of the videos and screenshots recorded during the cypress run execution. Videos with higher resolution make debugging simpler and look better when shared with other members of the team. The problem Let's look at the Wikipedia.com website.
