Chapter 5: Testing and Automation with Python

Software testing is the process of validating an application or a program as per user requirements or desired specifications and evaluating the software for scalability and optimization goals. Validating software as a real user takes a long time and is not an efficient use of human resources. Moreover, testing is not performed only one or two times, but it is a continuous process as a part of software development. To rescue the situation, test automation is recommended for all sorts of testing. Test automation is a set of programs written to validate an application's behavior using different scenarios as input to these programs. For professional software development environments, it is a must that automation tests get executed every time the source code is updated (also called a commit operation) into a central repository.

In this chapter, we will study different approaches to automated testing, followed by looking at different...
