Software Testing Techniques

Software Testing Techniques

1. Unit Testing

   • Unit Testing is a level of software testing where individual units/ components of a software are tested. The purpose is to validate that each unit of the software performs as designed.
     • In object-oriented programming, the smallest unit is a method, which may belong to a base/ super class, abstract class or derived/ child class.

2. White Box Testing

   • Testing based on an analysis of the internal structure of the component or system.
     • white-box test design technique: Procedure to derive and/or select test cases based on an analysis of the internal structure of a component or system.

3. Error-based testing

   • Testing where information about programming style, error-prone language constructs, and other programming knowledge is applied to select test data capable of detecting faults, either a specified class of faults or all possible faults.

4. Scenario based evaluation

   • Scenario testing is a software testing technique that makes best use of scenarios. Scenarios help a complex system to test better where in the scenarios are to be credible which are easy to evaluate.
     • Methods in Scenario Testing:
       • System scenarios Use-case and role-based scenarios.
