The life cycle of software development today includes a wide variety of the quality and security of the testing techniques at all stages. The frequent testing that is done throughout the DevOps pipeline is very crucial given the pace of development which is ever increasing. One among the common testing method is that all the companies must take note that the product which they push out are secure and of high quality. This is all about black-box testing.
What Is Black Box Testing?
This is a broad category that includes a wide variety of techniques and technology which check the software from the outside. And that too is done without scanning the code.
The black box testing also refers to the various type of software test which examines all types of application and that too without knowing anything about the internal design, structure, or implementation of the software project.
The black box testing can also be performed at multiple levels and this includes unit testing, integration testing, system testing, or acceptance testing. At all these levels, the black box testing conducts a test on the input and output of an application. This is done to take note and confirm that the software runs as is wanted and is running under varied conditions and with the aim to uncover and remediate all types of errors.
Types of Black Box Testing
Black box testing usually refers to a considerably wide variety of tests. Out of the common types of black-box testing, three of them are
1. Functional testing,
2. Non-functional testing, and
3. Regression testing.
Difference between Black Box vs. White Box Testing
The black box and the white box testing always are proportionate to each other as they are used for examining and evaluating the applications in two different manners.
The black box testing is used in the input and output with very less knowledge of the code and it does not require any software development expertise. The white box testing needs proper knowledge of the application and is generally done by the developers or testers who are proficient in software development.
The White box testing tests the various aspects of the software which is not possible to access by the black box testing like the source code, syntax, design, architecture, and configuration. The test cases for the black box and white box testing is also very different. The black box testing is also based on the requirements and specifications. Also, the white box testing is also based on the detail of the design.

Black Box Security Testing
The attention to application security increases and the application security testing tools are gaining more attention. Black box testing is now an important method of application security testing. The black box security testing only puts focus on the security of an application at the same time examining it from the outside and not testing the code from the inside of the application.
A proper example and considered as one advanced black-box security testing technology is dynamic application security testing. Here, the security of the application is checked during the runtime. The team at dynamic application security testing helps in uncovering the major security risks like cross-site scripting, SQL injection or command injection, path traversal, and insecure server configuration.
One main advantage of black-box testing is that security testing with tools similar to DAST can be used to detect vulnerable security issues which the white box testing tools similar to the SAST help in scanning the code for the vulnerable secure points while at rest might miss.
The prime benefit of black-box testing is that they help in producing a low number of false positives and also provides the security teams very few false positives and an accurate view of the exploitability of the application.
Black Box Penetration Testing
Another black box security testing method is penetration testing. In penetration testing, the testers try to copy the behavior of the malicious players while attacking the application from the outer side. The testers always try to create an attack scenario that is closest possible to how the black hat hackers can behave in order to ensure that all the attack vectors are covered too.
The traditional penetration testing was a manual attempt but today only a few solutions are available in order to perform the heavy penetration lifting by making the process work automatically.

Black Box Testing: Ensuring Quality and Security
The most important principle in software development is testing and testing cannot be completed without doing the different types of black-box testing that have been touched upon here.
The software development organizations such as Amplework are always in a race to create the most innovative future products. They also ensure that they are secured and of high quality while sticking to the competitive release cycles which is also not an easy thing. Black box testing is a very essential component that allows us to move and prick our software in order to be sure that we are releasing the best products that are possible and which is why we can be sure that our customers will keep returning for more.
