What Is Domain Analysis Testing?

A lot of difficulties arise if a system has multiple value parameters. In such a case, functional testing[1] may take too much time. Fortunately, QA field is full of various effective techniques and methodologies.

If a wide range of variables should be tested together, then domain analysis principle is applied. This technique is based on merging equivalence class and boundary value testing[2]. But domain analysis testing is performed when multiple variables should be checked simultaneously, while equivalence class and boundary value testing are focused on testing individual parameters.

Why is There a Need to Test Multiple Variables Simultaneously?

• Usually there is no enough time to create test cases for every variable.
• Very often different variables are interconnected and interdepended. In such a case, it is impossible to detect bugs by testing variables separately.

During mobile testing[3] or web application testing[4], the technique of domain analysis helps to define the most effective test cases needed for checking multiple variables together. This method prevents the incorrect implementation of boundaries.

What Errors May Occur in Two Interacting Parameters?

• A sifted boundary (vertical or horizontal displacement)
• A tilted boundary (incorrect angle)
• A missed boundary
• An extra boundary

But sometimes several variables may be connected. It is a real challenge for the specialists from software testing company. The complex systems require much tester’s attention and efforts to be thoroughly checked.
