How To Run Cypress Tests In Azure DevOps Pipeline

When software developers took years to create and introduce new products to the market is long gone. Users (or consumers) today are more eager to use their favorite applications with the latest bells and whistles. However, users today don’t have the patience to work around bugs, errors, and design flaws. People have less self-control, and if your product or application doesn’t make life easier for users, they’ll leave for a better solution.

Guide To Find Index Of Element In List with Python Selenium

In an ideal world, you can test your web application in the same test environment and return the same results every time. The reality can be difficult sometimes when you have flaky tests, which may be due to the complexity of the web elements you are trying to perform an action on your test case.

Getting Rid of Technical Debt in Agile Projects

Technical debt was originally defined as code restructuring, but in today’s fast-paced software delivery environment, it has evolved. Technical debt may be anything that the software development team puts off for later, such as ineffective code, unfixed defects, lacking unit tests, excessive manual tests, or missing automated tests. And, like financial debt, it is challenging to pay back.

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.
