Functional testing
Verify your API's accuracy, reliability, and compliance with functional specifications.
Overview
Functional testing focuses on ensuring that your API delivers the expected responses under various conditions. This template identifies the functional test cases to test the functionality of the fictional Intergalactic Bank API. Use this template as a reference for creating your functional testing collection to help your fellow backend developers get familiar with your service and validate that the changes made conform to the requirements.
What is API functional testing?
API functional testing is a crucial aspect of software testing focused on verifying the correctness, reliability, and compliance of an API with functional specifications. It involves testing the API's functionality by sending various requests and validating the responses against expected outcomes under different conditions.
Why is API functional testing important?
API functional testing plays a vital role in ensuring the quality and reliability of an API. By rigorously testing the functionality against predefined specifications, it helps identify any deviations or inconsistencies early in the development lifecycle, thereby minimizing the risk of bugs, errors, and regressions in production.
What does the API functional testing template contain?
Our API functional testing template includes test cases designed to validate the functionality of the fictional Intergalactic Bank API. It covers various scenarios to ensure that the API returns appropriate responses in compliance with functional requirements.
How do you perform functional API testing with the template?
Here are a few simple steps for leveraging this template effectively to perform functional API testing on Postman: Step 1. Explore the template: Get familiar with the template, go through the documentation, and run the sample tests to get the hang of performing functional testing on Postman. Step 2. Identify funtional workflows: Identify the main functional workflows or scenarios within your API and create test scenarios that cover these cases. Step 3. Write test scripts: Update the template or create a new collection and set up requests for your workflows. Write test scripts for your test cases on Postman or use Postbot to generate test scripts instantly. Step 4. Execute functional tests: Update the template or create a new collection and set up requests for your user flows. Develop test scripts for each end-to-end scenario on Postman. Bonus: Use Postbot to generate test scripts instantly. Step 5. Execute end-to-end tests: Run the functional tests against your API and monitor the test results for any deviations from the expected behavior.
