Ensuring software quality is an essential part of developing business-critical web solutions for companies and so quality assurance is also a high priority at TYPONiels.
For continuous testing I write automated tests with different test frameworks like PHPUnit, Codeception and and execute a specially developed process for static code analysis for every code change. Here, all code is checked for bad programming paradigms and optimized right away. Output of these analyses are then different metrics, which allow an easy evaluation of the quality.
I would be happy to advise you on the subject of software quality without obligation.
