Invalid chai property jsonschema

I'm working on the API automation using mocha and chai.

I need to compare the response of the api and compare it with chai jsonschema assertion.

expect(response).to.be.jsonSchema(expectedResponse)

I get the following error,

 Error: Invalid Chai property: jsonSchema

Solution

You have not mentioned the imports of your test file and most likely that is the place where you are making a mistake.

These sorts of errors are thrown by the chai library when you try to use something which is not in-built in your case the chai-json-schema plugin.

Try to update your imports as below:

const {expect} = require("chai").use(require('chai-json-schema'));

This will add the required methods of the chai plugin to your expect object.
