What is Black Box testing method?

Black box (Opaque, Closed box, Function-centric) is a testing method that examines the functionality of an application without peering into its internal structures or workings. This method of testing can be applied virtually to every level of software testing: unit, integration, system and acceptance. It is sometimes referred to as specification-based testing.

It is a powerful method, which is used to test the system against external factors responsible for possible failures. It focuses on the input, which goes in the software and the output, which this process produces. It is based on checking the system to validate against predefined requirements and emphasizes on the ‘software behavior’.

The Black box is commonly used for testing software usability, overall system functionality, getting a broader picture of the software, viewing the application from the user’s point of view and testing the whole system rather than different separate modules.

Black box testing evaluates all relevant subsystems, including UI/UX, web server or application server, database, dependencies, and integrated systems. It performs DAST (Dynamic Application Security Testing), which carries out tests in staging or production and provides feedback on compliance and security problems.

The process of the testing is taken in several consecutive steps.

About SmartState

Launched in 2019 and based in Dubai, SmartState is one of the leading DeFi security auditing firms. We conduct security tests and check the code core, smart contracts and blockchain for all types of errors, vulnerabilities and other issues.

Although SmartState gave a start to operations with smart contract auditing of DLT-projects, from the very beginning, we made our services surpass the classic purview of smart contract audit and security testing.

We specialize in manual testing, so the SmartState’s tech team of white-hat security professionals measure up a project’s git and offer guidelines and recommendations for its further advancement.

Security audit reports review the threats and vulnerabilities with which codebases may be exploited in the future, as the network achieves scalability and expands to accommodate more use cases and functionality.
