Writing Test Scripts in Postman
- Test scripts, written in JavaScript, are executed after receiving API responses (i.e. script runs after the response is received from the server). The pm.response object and the built-in Chai.js library enhance the process of creating readable and effective test assertions.
- Developers can utilize snippets and pre-written blocks of code to expedite the creation of test scripts. These snippets are available in the side pane of the test editor, covering a range of utility functions.
- Can check the status codes, response body, or anything in response, and also it’s used to validate and verify whether the response meets the expected criteria.
Example of Writing a Basic Test
- Starts with pm.test.
- First parameter: name of the test.
- Second parameter: A function that contains assertions like pm response status.
