D. usability testing
Step-by-step explanation:
A software can be defined as a set of executable instructions (codes) or collection of data that is used typically to instruct a computer how to perform a specific task and to solve a particular problem.
A software development life cycle (SDLC) can be defined as a strategic process or methodology that defines the key steps or stages for creating and implementing high quality software applications. There are seven (7) main stages in the creation of a software and these are;
1. Planning.
2. Analysis and requirements.
3. Software design and prototyping.
4. Development (coding).
5. Integration and testing
6. Deployment.
7. Operations and maintenance.
Usability testing is a testing technique used by a software development team to test a developed code rather than just the functionality of the code.
The main purpose of usability (user experience) testing is to determine how easy, user-friendly or difficult it is for end users (real people) to use a software application or program.
