Testing a product before its release is one of the last and most important aspects of the development cycle. This step in the process is commonly known as quality assurance or simply QA. Quality assurance is a key component in the creation of any product, especially computer software. Proper quality assurance testing provides objective insight into the effectiveness and performance of your product, and it allows you to quickly solve any previously unknown problems as well as check to see if there are areas of underperformance .A software quality assurance tester is responsible for thoroughly assessing and examining a piece of software or code to make sure it meets or exceeds your expectations. The quality assurance process includes testing and documenting the responses to various inputs, recording the speed of execution for the application, and identifying any possible bugs or system errors. Testers come from a wide variety of backgrounds and can be leveraged to assess any number of software types.
Quality assurance testing specialists are experienced professionals who are highly computer literate and generally possess specialized knowledge of many different computer software and hardware elements. The skills and knowledge a tester possesses is engaged when a client’s software is run through multiple combinations of software and hardware while concurrently being executed with other applications. After running tests, the QA tester then identifies and documents the exact set of variables and circumstances that produced notable responses, and reports them back to the client. These reports can be generated with reliability from anywhere the software is accessible, making freelance testers an invaluable asset to any team.
