Mastering WireMock for Effective API Testing

Discover how to effectively test APIs in isolation by utilizing WireMock, a powerful tool to simulate API behavior

What you’ll learn
By the end of the course, students will be proficient in using WireMock and JUnit to create robust, high-quality tests
Match incoming requests based on URL, headers, body content, and more
Advanced Matching, use JSONPath, XPath, and regular expressions for complex request matching
Static Responses: Define fixed responses for specific requests & Dynamic Response Templating: Generate dynamic responses using Handlebars templates
Custom Matchers, Transformers & Extension API: Extend WireMock’s functionality with custom extensions
Stateful Behavior Scenarios: Define and manage stateful interactions to simulate complex workflows

Requirements
Basic Java Programming: Understanding of Java syntax, object-oriented programming concepts, and basic data structures.

Description
Unlock the power of API testing with our comprehensive course, “Mastering WireMock for Effective API Testing.” This course is designed to take you from the basics to advanced techniques, ensuring you can leverage WireMock to its fullest potential.WireMock is a popular open-source tool for API mock testing. It helps create stable test and development environments, isolate from unreliable third parties, and simulate non-existent APIs.WireMock supports creating mock APIs in code, via its REST API, as JSON files, and by recording HTTP traffic. It has a rich matching system and can dynamically generate complex responses using Handlebars-based templating. Integration is easy due to its numerous extension points and comprehensive APIs. WireMock spans across multiple programming languages and technology stacks. It can run as a library or client wrapper in many languages, or as a standalone serverCourse Modules:Introduction to WireMock: Understand what WireMock is, its use cases, and how to set it up.Basic Stubbing and Request Matching: Learn to create simple stubs and match requests using URL, method, headers, and body.Advanced Request Matching: Dive into JSON schema matching, form parameters, and XPath/JSONPath matchers.Response Templating: Master basic and advanced response templating with functions and helpers.Stateful Behavior and Scenarios: Explore defining scenarios, stateful stubs, and global state management.Extensions and Customization: Create custom matchers and transformers, and use the Extension API.Integration with Other Tools: Integrate WireMock with JUnit, other testing frameworks, and CI/CD pipelines.Mocking Different Protocols: Mock HTTP/HTTPS protocols.WireMock Cloud: Get an overview of WireMock Cloud and learn how to set it up and use it.

Who this course is for
API Developers: Developers who create and maintain RESTful APIs and need to test their endpoints without relying on external services.
Test Automation Engineers: Professionals who automate tests for applications that interact with external APIs and need to simulate various scenarios.
Integration Testers: Testers who focus on integration testing and need to mock external services to validate the interactions between different system components.
