📓Test Cases

List of few common test actions to write on test case

API Test Actions

Test Action	Description
Verify Correct HTTP Status Code	Ensure that the API returns the expected HTTP status codes for different operations.
Verify Response Payload	Check the validity of the response payload, ensuring correct field names, types, and values.
Verify Response Headers	Validate the response headers returned by the API, considering security and performance implications.
Verify Correct Application State	Inspect the application state after API requests to ensure the desired changes have been applied correctly.
Verify Basic Performance Sanity	Check if API operations are completed within a reasonable time frame, identifying potential performance issues.
Verify Authentication	Validate the API's handling of authentication mechanisms, including proper usage of credentials and tokens.
Verify Authorization	Ensure that the API enforces proper authorization rules, restricting access to resources based on user permissions.
Verify Error Handling	Evaluate how the API handles errors, ensuring appropriate error responses with meaningful messages and codes.
Verify Data Manipulation	Test data manipulation operations, such as creating, updating, and deleting data, ensuring integrity and consistency.
Verify Security Vulnerabilities	Conduct security testing to identify and address common vulnerabilities in the API, such as injection or XSS attacks.
Verify Boundary Conditions	Test how the API handles edge cases and boundary conditions, ensuring appropriate responses and error handling.
Verify Integration	Validate the integration of the API with other systems or third-party services, ensuring seamless data exchange.

Example Scenario:

Let's consider an example scenario for an e-commerce API.

Scenario: Verify Product Creation API

Verify API Test Action	Description
Verify Correct HTTP Status Code	Check that the API returns a 201 CREATED status code upon successfully creating a new product.
Verify Response Payload	Ensure that the response payload contains the created product's information with correct field names and values.
Verify Response Headers	Validate that the response headers include the appropriate content-type and caching headers for the product.
Verify Correct Application State	Manually inspect the product list or search for the newly created product to confirm its existence and details.
Verify Basic Performance Sanity	Measure the time taken for the API to create the product, ensuring it completes within an acceptable time frame.
Verify Authentication	Validate that the API requires proper authentication, such as an API key or access token, for the product creation.
Verify Authorization	Ensure that only authorized users with specific roles or permissions can create products through the API.
Verify Error Handling	Test error scenarios, such as providing invalid or missing data, and verify that appropriate error responses are returned.
Verify Data Manipulation	Check that the newly created product is stored correctly and its details can be retrieved or updated as expected.
Verify Security Vulnerabilities	Perform security tests to identify and address vulnerabilities, such as injection attacks, in the product creation API.
Verify Boundary Conditions	Test edge cases like creating a product with an empty name or an excessively long description to validate appropriate handling.
Verify Integration	Ensure seamless integration of the product creation API with other systems, such as verifying data synchronization with a product catalog.
