The document discusses the automation of testing REST web services, focusing on various methods to achieve this with less coding. It outlines the types of checks, ways to automate testing using existing products or libraries, and the development of a custom test framework. Additionally, it compares traditional coded approaches with less coded methods and includes a real-world application example.

BUILDING YOUR OWN TEST FRAMEWORK
Creating automated tests cases by writing their scenarios and execution logic together in
java classes;
1
Creating automated tests cases by writing their scenarios and execution logic separately;2
Choosing the second point allows to create automated tests without coding in the future.
There are two questions:
• How to generalize execution logic?
• How to represent a format of writing tests?
