Starting &#038; growing a QA Testing career

The QA testing career includes following an often long, winding road filled with fun, chaos, challenges, and complexity. Financially, the spectrum is broad and influenced by location, company type, company size, and the QA tester’s experience level. QA testing is a profitable, enjoyable, and thriving career choice.

Project Goal Prioritization in Context of Your Organization&#8217;s Strategic Objectives

One of the most important skills for leaders to have is the ability to prioritize. To understand how we can organize all of the tasks that must be completed in order to complete a project, we must first understand the business we are in, particularly the project goals. There might be several project drivers that stimulate project execution and motivate a company to allocate the appropriate funding.

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.

How To Choose The Best JavaScript Unit Testing Frameworks

JavaScript is one of the most widely used programming languages. This popularity invites a lot of JavaScript development and testing frameworks to ease the process of working with it. As a result, numerous JavaScript testing frameworks can be used to perform unit testing.
