This document discusses REST testing and the Rest-Assured library. It begins with an overview of REST including that it is a set of architecture principles for distributed applications using HTTP. It then discusses constraints of REST like being stateless and having a uniform interface. The document outlines what to test for REST APIs like business logic, data format, and naming conventions. It introduces tools for REST testing like Postman and SoapUI. Finally, it provides details on the Rest-Assured Java library for testing REST services including advantages like its fluent API and response assertions.

6. What is REST???

7. What is REST???
It’s not a protocol

8. What is REST???
It’s not a protocol
It’s a set of architecture principles (according to these principles
server interacts with clients in distributed applications)

9. What is REST???
It’s not a protocol
It’s a set of architecture principles (according to these principles
server interacts with clients in distributed applications)
HTTP protocol is used as communication protocol

10. What is REST???
It’s not a protocol
It’s a set of architecture principles (according to these principles
server interacts with clients in distributed applications)
HTTP protocol is used as communication protocol
It was developed to overcome the limitations of SOAP and make
web services lightweight

21. Tools for testing
• Postman
8/30/2017 21
Extension for Google Chrome
It allows us:
• send requests
• capture it
• show us history

22. Tools for testing
• Postman
• Advanced Rest Client

More one extension for Google
Chrome
It allows us to send and capture API
requests, view responses etc.

23. Tools for testing
• Postman

30. Advantages of REST Assured
• JsonPath and XmlPath
8/30/2017 30

31. Advantages of REST Assured
• JsonPath and XmlPath
• Supports all HTTP methods
8/30/2017 31

32. Advantages of REST Assured
• Response deserialization into objects
8/30/2017 32

33. Other advantages
• Rest mapping
• Validation json according to json schema
• Working with json and xml
• Custom (de)serializers
• Timeouts in tests
• Testing different authentication methods and
SSL
