Efficient Test Cases with Equivalence Partitioning & BVA


What is Black Box Testing?

It is also known as behavioral, opaque-box, closed-box, specification-based, or eye-to-eye testing.

Black Box testing is a type of Dynamic Testing, an effective software testing automation, and it is an efficient way to evaluate the functionality of the Application Under Test (AUT)without analyzing its internal code structure.

It’s one of the most powerful methods of Testing because the tester doesn’t need to have deep knowledge about the product itself. It’s also the most well-used method of testing and occurs throughout the development cycle and Testing Life Cycle i.e in the Unit, Integration, System, Acceptance, and Regression Testing stages.

However, one important note is while multiple valid partitions or boundaries can be tested at the same time, sometime multiple Invalid partitions and Invalid boundaries should not be tested in the same test case. The reason is some systems might stop processing when they encounter the first problem, and only appear the error for that specific problem only. In the case of the example above: we should not test ID 1000 for (3) and (4) at the same time because the system might stop processing from (3) and only appear error of (3) without checking (4). If the system is not stopping at its first problem, or multiple error messages can appear at the same time, then you can proceed to test multiple of them without a problem.

Discover the 5 Key Benefits of Software as a Service (SaaS)

  Software as a service (SaaS) revolutionizes the way businesses access and utilize software testing and quality assurance processes through cloud computing. Unlike the traditional model that requires extensive setup, SaaS offers a hassle-free alternative. By leveraging a vendor’s cloud-based software, users can access applications remotely via the web or an API, akin to a rental arrangement. This approach offers numerous advantages, including: Streamlined Deployment: With SaaS, software is pre-installed and configured, eliminating the need for time-consuming installations. By provisioning a server in the cloud, you can have the application up and running within hours. This accelerated setup minimizes deployment obstacles and delays. Cost Efficiency: SaaS operates in a shared or multi-tenant environment, resulting in cost savings for hardware and software licenses compared to the traditional model. This affordability enables small and medium-sized businesses to leverage software th...
