Functional Testing of a Web Application: a Complete Checklist

Before pushing a project to production, a tester should not only follow specification requirements but also take into account the big importance of functional specification that can be applied to software.

Therefore, to not be afraid to push a project to independent testing, you should perform functional software testing on the basis of a checklist. Further, we’ll talk about it.
