This document discusses API test automation, including what it is, why it should be done, who should do it, common tools and frameworks used, considerations for microservices, and examples. API test automation involves testing application programming interfaces without a graphical user interface to test components in isolation faster. It is useful for developers, testers, and consumers and allows APIs to be provided as external products. Popular tools include SoapUI, Postman, and libraries like rest-assured and requests. When moving to microservices, APIs will compose granular services and be a primary source of testing.

3. WHAT IS API TEST AUTOMATION ?

4. WHY WOULD YOU DO IT ?
• You want to perform your tests without a GUI
• You want to test faster
• You want to access internal components of the system
• You want to test components in isolation
• You want to provide your API as a product to the external
world

5. WHO SHOULD DO IT ?
• Devs
• Testers
• Consumers

6. TOOLS AND FRAMEWORKS
• Soapui
• Postman
• Swagger-ui
• rest-assured (Java)
• rest-client (Ruby)
• requests (Python)
• Mock servers (ex: mountebank)

7. MOVING INTO MICROSERVICES
• Microservices have more granular services
• APIs would be a composition of these services
• APIs are going to be your main source of testing
