Job Summary :
The API Tester is responsible for testing and validating APIs to ensure they meet the requirements, are free of defects, and work as intended within the application. The role involves creating and executing test cases for RESTful APIs, SOAP APIs, and Web Services. The API Tester works closely with developers, QA engineers, and product teams to ensure seamless integration of APIs into the system and that all business requirements are met.
Key Responsibilities :
API Test Planning :
Understand API requirements, specifications, and documentation to create detailed test plans and test cases.
Collaborate with development teams to review API functionality and design.
Identify test scenarios based on the APIs endpoints, functionality, and integration with other services or systems.
Test Execution :
Perform manual and automated testing of RESTful APIs, SOAP APIs, and Web Services.
Validate API responses, including status codes, response times, and data accuracy, to ensure they meet expected outcomes.
Test different API request types (GET, POST, PUT, DELETE) for various scenarios (positive, negative, edge cases).
Conduct functional, security, performance, load, and integration testing of APIs.
Automation :
Develop and implement automated API tests using tools like Postman , SoapUI , JMeter , RestAssured , or other relevant frameworks.
Write test scripts to automate repetitive test cases and improve test coverage.
Integrate automated tests into continuous integration/continuous deployment (CI/CD) pipelines to ensure ongoing validation of APIs.
Defect Tracking and Reporting :
Identify, document, and track defects found during testing and collaborate with development teams for resolution.
Maintain clear and detailed defect reports with steps to reproduce, screenshots, and logs.
Perform regression testing to verify that fixes or changes do not impact the functionality of other parts of the API.
Performance & Load Testing :
Conduct performance and load testing to evaluate API performance under various conditions (e.g., stress, scalability).
Identify and report any performance bottlenecks, latency issues, or resource consumption concerns in the API.
Documentation :
Document test plans, test cases, test scripts, and results clearly and accurately.
Provide regular updates on test progress, status, and defect resolution to stakeholders.
Maintain an updated repository of test cases, results, and logs.
Collaboration & Communication :
Work closely with developers, product managers, and other stakeholders to understand API functionality and business requirements.
Participate in sprint planning, daily stand-ups, and other Agile processes to ensure timely completion of testing tasks.
Provide input into the design and architecture of APIs, focusing on potential testing concerns and best practices.
Continuous Improvement :
Stay up-to-date with the latest trends and tools in API testing and quality assurance.
Propose and implement improvements to testing processes and methodologies.
Continuously review and improve test strategies and frameworks to ensure higher efficiency and test coverage.
Required Skills and Qualifications :
Education : Bachelors degree in Computer Science, Information Technology, or a related field (or equivalent experience).
Experience : Proven experience in API testing, preferably with knowledge of RESTful APIs, SOAP APIs, and Web Services.
Technical Skills :
Strong knowledge of HTTP, JSON, XML, and other web services protocols.
Experience with testing tools such as Postman , SoapUI , JMeter , RestAssured , or Swagger .
Knowledge of database querying (SQL) and integration testing.
Experience with version control tools (e.g., Git , SVN ).
Automation : Experience in automating API tests using frameworks like RestAssured , JUnit , or TestNG .
Problem-Solving : Strong analytical and troubleshooting skills to identify and resolve issues in API integration.
Documentation : Ability to create clear and concise test documentation and reports.
Communication : Strong verbal and written communication skills to effectively interact with team members and stakeholders.
Knowledge of Agile : Familiarity with Agile methodologies and the ability to work in a fast-paced, iterative development environment.
Preferred Skills :
Performance Testing : Experience with performance testing tools like Apache JMeter , Gatling , or LoadRunner .
CI/CD Integration : Experience with CI/CD tools (e.g., Jenkins , CircleCI ) and integrating API tests into automation pipelines.
Security Testing : Knowledge of security testing concepts and tools related to API testing, such as OWASP vulnerabilities, JWT , and API security practices.
Cloud Services : Familiarity with cloud platforms (e.g., AWS, Azure, Google Cloud) and API integration in cloud environments.
Scripting : Familiarity with scripting languages such as Python , JavaScript , or Shell for writing test automation scripts.
