API TESTING

Index:

• Introduction to API Testing:

• Understanding APIs and their role in software development.
• Differences between API testing and GUI testing.
• Benefits of API testing in ensuring robust and scalable applications.

• Types of APIs:

• Overview of different types of APIs (RESTful APIs, SOAP APIs, GraphQL).
• Characteristics and use cases for each type of API.
• Choosing appropriate API testing approaches based on API type.

• API Testing Tools and Frameworks:

• Introduction to popular API testing tools (Postman, SoapUI, Insomnia, Newman).
• Setting up and configuring API testing environments.
• Writing API tests using tools and scripting languages (e.g., Postman scripts, Python requests library).

• API Test Design and Planning:

• Understanding API endpoints, methods (GET, POST, PUT, DELETE), and parameters.
• Designing test cases for API functionality, error handling, and edge cases.
• Developing API test scenarios based on requirements and user stories.

• Testing Fundamentals and Techniques:

• Performing CRUD operations (Create, Read, Update, Delete) on API resources.
• Verifying HTTP status codes and response payloads.
• Handling authentication mechanisms (Basic Auth, OAuth, API keys) in API testing.

• API Security Testing:

• Identifying and testing common API security vulnerabilities (SQL injection, XSS, CSRF).
• Implementing security testing techniques (input validation, encryption, token management).
• Using tools for API security testing and vulnerability assessment.

• Performance and Load Testing of APIs:

• Evaluating API performance metrics (response time, throughput, latency).
• Conducting load and stress testing on APIs using tools like JMeter or Gatling.
• Analyzing performance test results and identifying bottlenecks.

• Automating API Tests:

• Introduction to API test automation frameworks (e.g., pytest, RestAssured).
• Writing automated API tests using scripting languages (Python, Java).
• Integrating API tests into continuous integration/continuous deployment (CI/CD) pipelines.

• Monitoring and Reporting:

• Implementing API monitoring strategies to track availability and performance.
• Generating API test reports with metrics, test coverage, and test results.
• Using logging and alerting mechanisms for proactive issue identification.

• Best Practices and Industry Standards:

• Best practices for API testing in Agile and DevOps environments.
• Compliance with API testing standards (OpenAPI, Swagger).
• Continuous improvement strategies for API testing processes.
