Welcome to "Isha Training Solutions"
Please note: This course is based on recorded live training sessions. As such, participant interactions are included and reflect real-time discussions commonly encountered in professional training environments. Learners are advised to review the available preview content to evaluate the instructional approach and technical depth before enrollment.
This course is designed for professionals seeking a structured understanding of API functional testing and the role APIs play within modern, service-oriented and microservices-based software architectures. The emphasis is on functional correctness, protocol-level behavior, and reliability of APIs as they operate within enterprise systems.
The curriculum focuses on practical API testing workflows and industry-aligned practices. Postman is used to design, execute, and automate functional API tests against RESTful services. Architectural context is provided to support reasoning about service interactions, dependency isolation, and testing strategies in distributed systems.
Upon completion, learners will be able to design, validate, and automate functional API tests and understand how API testing integrates into modern software delivery and quality engineering processes.
What You’ll Learn:
API Systems Fundamentals & Lifecycle Governance: Understand APIs and web services, enterprise architecture styles (monolithic, SOA, microservices), and how APIs are designed, published, managed, and consumed across their lifecycle.
REST Semantics & HTTP Protocol Mechanics: Gain deep understanding of RESTful API behavior, HTTP protocol internals, verbs, methods, headers, status codes, statelessness, and CRUD-to-HTTP mappings.
Functional API Test Design Using Postman: Perform functional API testing using Postman requests, collections, environments, variables, pre-request scripts, and test scripts.
Request/Response Validation & Schema Compliance: Validate API requests and responses using JSON processing, JsonPath expressions, schema definitions, and schema validation techniques.
Data-Driven Functional Test Execution: Execute repeatable functional API tests by externalizing test data and leveraging Collection Runner for data-driven execution.
Service Virtualization & Dependency Isolation: Implement API mocking strategies and configure mock servers using Postman and WireMock to isolate downstream dependencies.
SOAP Protocol Testing & Legacy Integration Validation: Test SOAP-based APIs alongside REST APIs, including request handling, properties, property transfer, and assertions.
End-to-End API Workflow Orchestration: Design and validate complex API workflows using API chaining techniques and OAuth-based authorization flows.
API Security Validation & Access Control Testing: Test secured APIs using Basic, Digest, API Key authentication, OAuth, and JWT, including token handling and authorization validation.
Automated API Validation & Assertion Frameworks: Automate API functional tests using Chai assertions, Faker for test data generation, and Lodash utilities for advanced validations.
Continuous Integration of API Test Suites: Integrate automated API test execution into CI/CD pipelines using Jenkins and GitHub Actions in version-controlled environments.
Distributed Systems API Testing & Contract Validation: Understand microservices communication patterns (REST, GraphQL, Kafka, MQTT), work with OpenAPI/Swagger contracts, and apply functional API testing on Spring Boot APIs backed by MySQL or H2 databases within Agile workflows using JIRA.
Why Take This Course?
This course focuses on functional validation of APIs as they operate in real systems, covering how APIs behave at the protocol level, how requests and responses are validated, and how correctness is ensured across different architectural styles and service boundaries.
It addresses API testing beyond isolated endpoints, emphasizing testing in the context of service-oriented and microservices-based systems, including dependency isolation, API workflows, and contract-level validation.
The course emphasizes practical API testing workflows used in professional environments, including functional test design using Postman, request and response validation, schema compliance, data-driven execution, and automation of repeatable test scenarios.
It provides hands-on exposure to API security testing, including authentication and authorization mechanisms such as API keys, OAuth, and JWT, with validation of secured endpoints and authorization flows.
Learners gain experience with service virtualization and mocking strategies to test APIs independently of downstream services, an essential practice in distributed and microservices architectures.
The curriculum integrates automation and continuous integration practices, demonstrating how functional API tests are executed as part of CI/CD pipelines using industry-standard tools and version control systems.
The course also offers architectural context for microservices communication patterns, including synchronous and asynchronous interactions, and how these patterns influence functional API testing strategies.
Finally, the course grounds all concepts in real-world implementation scenarios, including testing APIs built using Spring Boot and relational databases, and understanding how API testing fits into Agile delivery workflows and team processes.
