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.

Best 13 Tools To Test JavaScript Code

Unit and functional testing are the prime ways of verifying the JavaScript code quality. However, a host of tools are available that can also check code before or during its execution in order to test its quality and adherence to coding standards. With each tool having its unique features and advantages contributing to its testing capabilities, you can use the tool that best suits your need for performing JavaScript testing.
