Limitations of Software Testing

Oct. 4, 2011 - PRLog -- It is very important to understand the limitations of testing. Testing does not assure success or even prove that a product will be usable. Even the most strictly conducted formal test cannot ensure that a product will be usable when released.

Let’s see some reasons of it:

Test results are not a proof that a product works.

Even in the case when it conducts the kind of test that gets statistically important results, this is still not a proof that a product works. Statistical importance is just a measure of the likelihood that one’s results were not due to chance. It is not an assurance, and it dependents the way in which the test was realized.

Partakers are seldom fully representative of the target population.

Partakers are only as representative as your ability to understand and classify your target audience. Market research is not faultless study, and the actual end user is usually difficult to identify and describe.

Testing is invariably a synthetic situation.

Testing portrays a description of the actual situation of usage and not the situation itself. The very act of conducting a study can itself influence the final results.

Testing is not always the best method that you can use.

There are a lot of methods aimed to estimate and amend products. It is not a secret that in some cases it is more effectual both in terms of time, cost, and precision to conduct an expert or heuristic estimation of a product rather than test it. This is particularly true in the early steps of a product when gross violations of usability principles abound. It is simply unnecessary to bring in many partakers to reveal the evident.

Nevertheless, in spite of these limitations, usability testing http://qatestlab.com/services/service-models/usability-te..., when carried out with care, solicitude and accuracy, for the appropriate reasons, at the appropriate time in the product development lifecycle, and as part of an overall user-centered design approach, is an almost faultless pointer of possible troubles and the techniques to resolve it. It minimizes the risk greatly of releasing an precarious or unbearable product. In almost every case: it is better to test than not to test.

Some type of usability testing fits into every phase of a development lifecycle. The type of software testing http://qatestlab.com/company/why-software-testing/ is recognized by the research questions asked, the state of the completeness of the product, and the time available for performing solutions to troubles revealed in testing.
