The importance of software testing has long been known. After a lot of discussion and evaluation, it became clear that errors occur in general because people tend to ignore optimization opportunities and probable errors.
The operation of the software that has not been rigorously tested can lead to serious bugs that lead users to various embarrassing situations. In this case, the only reasonable way out is to analyze and predict errors, as well as correct them on time to avoid any inconvenient situations in the future and to ensure the stability and reliability of the system.
As in any other field, software testing is surrounded by many myths, but still, the facts remain the facts.
Testing increases the cost of development
As the saying goes, “If you don’t want to pay for testing during development, you will have to pay for technical support and bug fixes when the product is released to the market.” Early testing helps reduce software maintenance costs.
Testing is a waste of time
Testing itself happens in parallel with development, so there’s no reason to think that testing takes a long time. The truth is that fixing bugs found during the testing phase takes time and effort.
Testing is carried out only after the completion of the development stage
Of course, testing depends on the written code. However, it is still necessary to perform software requirements checks and create test artefacts, both of which can be completed before the software product is complete.
Some of the most common myths surrounding the software industry amaze and shock us!
Exhaustive testing is possible
In reality, it is impossible to say that testing is 100% and that all bugs are easy to predict and fix. The fact is that most problems can indeed be predicted during the testing phase, but exhaustive testing is hardly possible. There may be conditions and scenarios in the system that are impossible during testing, simply because the system never works according to them.
The purpose of testing is to 100% protect software from bugs
The goal of testing is to find and identify as many bugs as possible. It’s impossible to even find them all, let alone fix them. It is a big mistake to believe that even modern automated testing tools can guarantee 100% protection of software from bugs.
Missing a bug is the fault of the tester
Evaluation of all possible flaws in terms of product quality is the joint responsibility of designers, who must give an exhaustive description of the system scenarios; developers, who must adhere to established rules and standards; testers who have to analyze all this data in the future and check all possible options for the system and indicate what needs to be fixed.
All responsibility for the quality of the software lies only with the tester
Again, this is one of the most common misconceptions about testing. Trying to find someone to blame when things get out of hand is highly unprofessional and won’t help fix the situation. The whole team is responsible for the quality of the product. Software testing teams ensure quality standards are met during product development. The control teams also point out problem areas to the development teams, and their joint responsibility is to fix the problem and release the software that runs without bugs.
Automated testing eliminates the need for manual testing
Complete automation of the testing process is not possible. Some degree of manual testing is always necessary, especially when it comes to human ingenuity. It is the responsibility of the test and quality assurance teams to assess the extent to which the system needs manual and automated testing.
In general, automated testing tools work best when it comes to simple, accurate, iterative testing that requires processing large amounts of information; but testing, which requires ingenuity and decision-making, is best done manually.
The job of a tester is devoid of creativity
A tester must have deep knowledge that helps him anticipate and find problems in particular software. This work requires a creative approach and a developed imagination since it is necessary to see the connection of all elements of the system and be able to predict possible failures in its work.
The tester is expected to understand the entire cycle of software operation, the interdependence and the mutual influence of its modules. Formulating test approaches, designing tests, and conducting tests are more than creative processes.
