Phase 1: Getting everything ready
Before you can start automating your API tests, you need to make sure you have everything you need. This includes setting up your testing environment, creating a collection of API requests, and familiarizing yourself with the API documentation. You should also have a clear understanding of the API’s functionality and the expected response for each request.
Setting up Postman
Postman is a powerful tool for API testing and automation. To get started, you will need to download and install the Postman app on your computer. Once installed, you can create a new collection by clicking the “New” button in the top left corner of the Postman window.
Listing/New Request
To get started, create a new request in your collection. This can be done by clicking the “New” button in the top left corner of your Postman window. From here, you can enter the URL for the API you want to test, along with any required headers or parameters.
Phase 2: Automated Tests Development
Once you have your collection of API requests, you can start developing your automated tests. This involves writing code that will run through each request in your collection and verify that the response is correct.
Random Data Generation
To make your tests more robust, it’s a good idea to use random data generation. This means that each time you run your tests, they will use different data to ensure that all possible scenarios are covered.
Mocking APIs
Another useful technique for API testing is mocking. This involves creating a mock API that mimics the behavior of the actual API, allowing you to test your code in a controlled environment.
Phase 3: Automated Tests Execution
Once you have developed your automated tests, you can start executing them. This involves running your tests against the API and verifying that the response is correct. You should also monitor the performance of your tests and make any necessary adjustments to ensure that they are running efficiently.
Verify ‘User is Deleted’ Request
One important test to include is the “User is Deleted” request. This involves sending a request to delete a user from the API and verifying that the user has been successfully deleted.
Conclusion
API automation and testing are essential for businesses that want to streamline their development processes and improve overall efficiency. By following the best practices outlined in this blog, you can ensure that your API tests are robust, efficient, and effective. Whether you are a small startup or a large enterprise, API automation can help you achieve your goals and stay ahead of the competition.
