How To Automate Mouse Clicks With Selenium Python

Sometimes, in our test code, we need to handle actions that apparently could not be done automatically. For example, some mouse actions such as context click, double click, drag and drop, mouse movements, and some special key down and key up actions. These specific actions could be crucial depending on the project context.

A Complete Guide To CSS Houdini

As a developer, checking the cross browser compatibility of your CSS properties is of utmost importance when building your website. I have often found myself excited to use a CSS feature only to discover that it’s still not supported on all browsers. Even if it is supported, the feature might be experimental and not work consistently across all browsers. Ask any front-end developer about using a CSS feature whose support is still in the experimental phase in most prominent web browsers. ????

Test Optimization for Continuous Integration

“Test frequently and early.” If you’ve been following my testing agenda, you’re probably sick of hearing me repeat that. However, it is making sense that if your tests detect an issue soon after it occurs, it will be easier to resolve. This is one of the guiding concepts that makes continuous integration such an effective method. I’ve encountered several teams who have a lot of automated tests but don’t use them as part of a continuous integration approach. There are frequently various reasons why the team believes these tests cannot be used with continuous integration. Perhaps the tests take too long to run, or they are not dependable enough to provide correct results on their own, necessitating human interpretation.
