Step 3: Click on Tests. Now in the right side pane, we can multiple snippets arrived. We can use any of the available snippet/test or create our own test based on our requirement. Code is written in JavaScript.
Step 4: We will write 2 Tests in JavaScript from the already available snippets from the right-hand side pane.
First Test: This will check whether the response time is less then 200ms
pm.test("Response time is less than 200ms", function () {
pm.expect(pm.response.responseTime).to.be.below(200);
});
Second Test: This will check whether status code is 200
pm.test("Status code is 200", function () {
pm.response.to.have.status(200);
});
Step 5: After that click on send button to send the request. We will see in the output terminal the results of the Tests.
By following these steps you have successfully tested your API.
Getting Started with Postman API Testing
Postman is an API(application programming interface) development tool that helps to build, test and modify APIs. Almost any functionality that could be needed by any developer is encapsulated in this tool. It is used by over 5 million developers every month to make their API development easy and simple. It has the ability to make various types of HTTP requests(GET, POST, PUT, PATCH), save environments for later use, converting the API to code for various languages(like JavaScript, and Python).
