The process for carrying out unit testing in decorators within NestJS includes the following steps:
Set up your testing environment: You will need to install the necessary dependencies and create a testing module to import the decorators you want to test.
Create a test file: Create a file with the .spec.ts extension and import the necessary modules from NestJS and your application.
Use @nest/microservices/testing
library: Since the decorator tests may require mocks, use the @nest/microservices/testing
library, which provides a convenient way to do this.
Create a test suite: Use the describe
function to create a test suite for your decorator.
Write test cases: Use the it
function to write specific test cases for your decorator.
Use TestBed.inject
method: Use the TestBed.inject
method to access the decorator and test its functionality.
Assert the results: Use assertion functions from a test framework like Jest or Jasmine to ensure that the decorator is working as expected.
Run the tests: Run the tests using a test runner like Jest or Karma to see if the tests pass.
Refactor and retest as necessary: If the tests fail, make changes to your decorator and re-run the tests until all the tests pass.
