Black box testing techniques

In this blog, we will learn about the black box testing and its test techniques. Today, we will dig into basic techniques out of two techniques (Basic and Advance).

Let’s get started

What is black box testing?

Testing the software without knowing the internal working of the software. It is a sort of software testing. It is used to verify the functionality of software/product without much having knowledge about internal structure, design, and code. Black box testing is also termed as behavioral testing, specification testing and functional testing.

Basic techniques

  1. Boundary value analysis (BVA)
    BVA is a technique of making sure that the functionality of the system is foreseeable for input and output boundary conditions. Boundary values are very important for testing as defects could be introduced at boundaries conveniently.
  2. Equivalence partitioning (EQP)
    Equivalence partitioning technique used to minimize the rework and time spent on the testing. Here, input values are divided into two parts – valid sets and invalid sets. Testing is performed using test data from defined sets.
  3. Use cases
    This technique used to recognize the test scenarios. It tests the whole system end to end. The scope of acceptance tests and gaps are identified easily under this technique.
  4. Live data and customer tests
    Software testing is performed at customer end with live data and real-world conditions. It helps to verify the system functionality under real conditions.
  5. Decision tables
    Large number of combinations of inputs and outputs are recorded under a table. It is used to illustrate the cause and their effects in a readable and compress format.

Please tell us about your black box test techniques knowledge before-and-after reading. I bet you’ll have something to say!!!
