Browse the basics of software testing to find out what black box testing is? If so, you have reached the perfect page, as this article will explain everything you need to know about black box testing, as well as all the basic concepts you need to know to start.

The software world is always changing, with innovations pouring into space every day. This also applies to the safety and quality testing techniques of the software. In these testing environments, the black box testing protocol is an ultra high and secure security standard.

What is a black box test

A term used to refer to a broad category of technologies that can inspect a piece of software without scanning its internal code. On the contrary, if you think of software as a box of code, everything is done from outside. Black box testing refers to any software technology that does not consider any internal design and implementation of the test software.

What is a black box test?

Black box testing is a broad category that includes various technologies and techniques that can inspect software externally without scanning code. Black box testing refers to any type of software testing that examines an application without understanding the internal design, structure, or implementation of a software project. This technique tests software by examining output and input without having to peek inside the software. Black box testing is the opposite of white box testing, which examines the interior of the software and verifies its internal code and overall structure.

Classification of black box tests:

Black box testing can be applied to three main types of testing: functional testing, non functional testing, and regression testing. The last one is used to check whether the new updated version of the software under consideration shows regression or degraded changes in functionality. As the name implies, functional testing is testing the functionality of software designed by developers. These tests examine everything related to the work of the software or application. Non functional testing is not related to whether the software performs its functions, but rather to examining how it performs specific functions. These tests rate the design and user management capabilities of the application or software. The scope of these tests includes speed during peak hours, interface and availability, compatibility with different hardware configurations, and exposure to security vulnerabilities during normal operations.

Advantages and disadvantages of black box testing:

Black box testing is one of the best ways to check software functionality at write time. All test cases of software or applications can be easily checked through black box testing programs, helping developers easily implement applications. These testing techniques do not require the tester to know the coding techniques used in the software, as they do not penetrate them. In addition, he can conduct testing independently and work in an impartial environment.

It also has some disadvantages; If the software considers too many inputs and outputs, it can be very tiring for testers to track results. In addition, the tester may not receive any test results at all, and even if he obtains these results, the results will not be specific to the entire software, which may make the testing experience cumbersome. In addition, these testing techniques cannot be used for software designed using advanced and complex coding techniques. Many functions required by testers, such as initialization and termination errors, incorrect functions, missing functions, data structure errors, and interface errors, cannot be detected through such testing techniques. Despite its drawbacks, black box testing is still a good way for engineers testing software to obtain a fair QA assessment. This is our brief explanation of what black box testing is and related concepts.
