White box and black box testing how to#

This testing is often provided by developers, but sometimes it is delegated to trained testers who know how to write code and can find the source of the problem. It complicates the QA process and requires a more sophisticated approach to every bug found. The main problem of this method is that, unlike the black box, we do not localize the problem and only detect it. It is assumed that we already know exactly how the element works and can predict its behavior during the test.

Improving the efficiency of QA in general.Īs we said, we work in the known areas of the app.

Examination of the surface areas of the product.

Search for deviations in program functions.

Optimization of the workflow in sprints.

White box and black box testing verification#

Cyclical verification of input data variation.Therefore, the tasks of its automation are: The correspondence between the expected result and the actual is checked. White box involves working with known variables. If failures are avoided, the element is working correctly, and if an error appears, the bug is caught, and it must be described by adding to the list of fixes for developers. The bottom line can be either positive or negative. Scripts allow you to transfer the approximate sequence of actions into the code and replay it cyclically. Most of the tasks are based on how users interact with the program. This basic testing method does not require special knowledge and extensive experience in QA. Testing the general condition of the program.Parallel checking of different versions of the product.Eliminating hassle when trying multiple values.Testing the functionality for stress resistance.Since the black box method involves working with an unknown object, the tasks of its automation are: Let’s take a closer look at both options in terms of automation. Namely, tests that are often repeated or constantly monitored by QA specialists. Since these checks take too much time, some can be automated. Anything that goes beyond expectations is considered bugs.

The test object, input data, and the expected result are indicated there. To optimize the workflow, they write cases at each step.

They are an integral part of the QA job and consume about 70% of resources in each sprint. There are 2 key methods of checking IT products for code and functional errors: black box and white box.
