This package provides some test utilities.
Install Package:
npm install --save-dev @jenkins-cd/js-test
Also see js-modules and js-builder.
This utility allows you to test some content using jsdom (a lightweight "headless" browser).
Here's an example from the Twitter Bootstrap Framework lib.
var jsTest = require("@jenkins-cd/js-test");
var JENKINS_PAGE = '<html><head resURL="/jenkins"></head><body><div id="divOnPage">Bootstrap is everywhere</div></body></html>';
describe("bootstrap3.js", function () {
it("- test", function (done) {
jsTest.onPage(function() {
var bootstrap3 = require("../js/bootstrap3");
var $bootstrap = bootstrap3.getBootstrap();
expect($bootstrap('#divOnPage').text()).toBe('Bootstrap is everywhere');
done();
}, JENKINS_PAGE);
});
});Note the call to
done();. This is a Jasmine "thing". It marks the end of an async test flow.
This utility makes it a bit easier to load the modules under test.
Without using requireSrcModule, tests would need to load source modules in an ugly/brittle path
(like in the above Bootstrap example) e.g.
var mathUtil = require('../../../src/js/utils/mathUtil');Using requireSrcModule, the above code would be:
var jsTest = require("@jenkins-cd/js-test");
var mathUtil = jsTest.requireSrcModule('utils/mathUtil');NOTE: This is integrated with js-builder. It will resolve the module being
required based on src/test builder configuration.
See the examples in js-samples, especially step-07-jsdom-tests and step-08-zombie-tests.
