The best software development companies provide thorough testing and quality assurance (QA) to ensure that the software functions as expected, is free of bugs, and offers a seamless user experience. Testing includes a range of approaches such as functional testing, security testing, performance testing, and user acceptance testing.Quality assurance is also designed to identify potential risks within an IT product's design, reevaluating those risks throughout development each time a new function is introduced.
Lastly in-depth testing is performed once a finished product has been produced in order to identify any issues that might have been missed and ensure that the product is functioning exactly as intended before it is brought to market.
