4 Traps or How not to Allow Introducing Bugs During Testing

Any tester knows that software testing and its planningis not so easy task and because of the incorrectly designed plan for the execution of the quality assurance the software product often remains with the unfixed errors.

Certainly, the project planning is an important factor for such types of checking, as mobile testing, websites testing, and desktop testing, but there are a lot of other reasons which can cause the new mistakes, except already existed in the application ones. 

What Causes the New Errors in the System Under Test?

  1. The development tools – visual tools, compilers, script writing tools, class libraries, and so on are often the reasons for the new errors. Thus, a testing team should always use the new software testing tools and their modern versions and also always be assured that they are compatible with the tested project.
  2. Badly documented code – having executed manual testing or automated testing, a tester can get lost in too much complex or badly documented code. Besides that, the efforts to sort out the situation take much team’s time, this phenomenon can lead not only to missing of the existed bugs in the system but also to the occurrence of the new ones.
  3. The absence of the qualified testers – if the project is difficult and requires special knowledge and skills, and the software company cannot provide the employees qualified in the necessary area, then the newcomers will not be able to help the project to become successful least of all. Moreover, the “green” testers always can mess the things up.
  4. The outdated automated scripts – if the test automation engineers have the already prepared scenarios which earlier were used in the similar projects or in the previous versions of the current project, but they do not update them, then there is a great probability of the additional errors implementation in the system.
