Learn to effectively integrate and build RESTful API clients into Java and Spring Boot applications using WireMock.
Key Features
- This course will help students to learn about how to write unit tests involving RESTful API integrations
- Write unit tests that cover all possible scenarios in a REST-based interaction
Book Description
WireMock is a simulator for HTTP-based APIs or MockServer. REST APIs are everywhere today as they're the modern and easiest way to build functionality and expose them to the real world. When it comes to writing unit test cases that involve REST-based interactions, there is always a challenge in testing error responses, network faults, latency, and timeouts. WireMock will solve the problem of application code that depends on an external service by mocking the actual service.
In the microservices architecture, It is pretty common for services to depend on one another and it's always a challenge to write test cases for code that depends on other external services. WireMock provides the necessary tools to simulate an external service so that code that depends on the external service can be tested; this helps to build a robust REST client.
This course covers the following techniques using WireMock:
· Service virtualization
· Simulating an external service
· Simulating latency
· Simulating error responses
· Simulating network errors
Learn to integrate the most powerful HTTP Mock library, WireMock, into your applications to build a resilient and robust REST API client.
