cf-test-stub
Cloudflare Stub Test Util
This module allows you to create stubs that get automatically restored between tests in Mocha.
Installation
$ npm install --save-dev cf-test-stub
Note: This module needs to be run within the context of Mocha
Usage
import assert from 'assert';
import {createStub, stubMethod} from 'cf-test-stub';
describe('exampleModule', () => {
it('should do something', () => {
const callback = createStub();
exampleModule.doSomething(callback);
assert.ok(callback.called);
assert.equal(callback.callCount, 1);
});
it('should do something else', function() {
const methodToStub = stubMethod(exampleModule, 'methodToStub', arg => {
assert.equal(arg, 'value');
});
exampleModule.doSomethingElse();
assert.ok(methodToStub.called);
assert.equal(methodToStub.callCount, 1);
// We can restore the original method ourselves, but cf-test-stub will
// restore it automatically after the test.
methodToStub.restore();
});
});
