2) Unit testing, validation testing, system testing and integration testing.
3) Unit testing, integration testing, validation testing and system testing.
4) Validation testing, system testing, integration testing and unit testing.

Answer 1

The normal order of activities in traditional software testing is: Unit testing, integration testing, validation testing, and system testing.

Step-by-step explanation:

The normal order of activities in which traditional software testing is organized is option 3) Unit testing, integration testing, validation testing, and system testing. This order follows a bottom-up approach, starting with individual units and gradually moving towards testing the entire system.

The first step, unit testing, focuses on testing individual components or units of the software. It verifies that each unit functions correctly on its own.

Next, integration testing is performed to test the interaction and integration of different units. It ensures that the units function correctly together.

After integration testing, validation testing is conducted to verify whether the software meets the specified requirements and performs its intended functions.

Lastly, system testing is carried out to test the entire system as a whole. It assesses the performance and functionality of the system in a real-world scenario.
