- Identify the API endpoints, request methods (GET, POST, etc.), headers, authentication, and expected responses.
- Use tools such as Postman, REST-assured (Java), or Python’s requests with frameworks like Pytest.
- Install necessary dependencies, configure your API keys, and set up base URLs.
- Define test cases for positive, negative, and edge scenarios, covering status codes, response payloads, and error handling.
- Use functions or classes to manage repetitive tasks such as API requests, authentication, or data validation.
- Use assertions to check status codes, headers, and JSON response content.
- Structure tests logically (e.g., by endpoints or features) and add proper documentation or comments.
- Integrate tests into CI/CD pipelines for continuous feedback on API performance and reliability.
How to write automation test cases in Postman?
- Test the response status code: Ensure the API returns the expected HTTP status code (e.g., 200 for success).
- Test the response header: Verify specific headers such as Content-Type or Authorization are present and accurate.
- Test the response time: Check if the API responds within acceptable time limits (e.g., less than 500ms).
- Test the response body: Validate the structure and values of the JSON or XML payload against expected data.
How to write code for automation testing?
- Identify Test Scenario: Install necessary tools, frameworks, and libraries (e.g., Selenium, Pytest, JUnit, or Cypress).
- Choose the Right Language: Select a programming language supported by the tools (e.g., Python, Java, or JavaScript).
- Write Test Cases: Identify test scenarios based on requirements. Write modular, reusable test scripts (e.g., for login, API, or UI validations).
- Run Tests: Execute the test scripts using a command or CI/CD pipeline.
- Report Results: Use reporting tools such as Allure or JUnit XML for detailed insights.
How does QA Touch help in writing automation scripts for API testing?
QA Touch helps with writing automation scripts for API testing by integrating with tools like Postman and RestAssured, providing a centralized platform to manage test cases, organize test data, and track execution results. It eases workflows with CI/CD integrations, enables collaboration through defect tracking, and offers detailed reports to optimize and maintain API test scripts effectively.
