I'm working on creation my own bootstrap project. At the moment I finished a lot of things, but now I meet the problem with unit tests for ReactJS components.
When I run application in browser - all works fine. I use RequireJS for lazy loading of needed modules. React compmonents wrapped into RequireJS modules and in browser all works as expected.
But when I trying to make unit tests for react components, RequireJs not load React. And React is undefined...
Here is the Gruntfile.js, where I create karma task.
Here is karma.config.js file with karma configurations.
Here is the test-main.js which is run the tests.
My test file looks like this:
define(['helper/utils', 'underscore', 'components/List'], function(utils, _, List){
describe("First test for example", function() {
it("TRUE should be TRUE :)", function() {
expect(true).toBe(true);
});
it("Test requirejs helper loading", function(){
expect(utils.testJasmine()).toBe("Jasmine");
});
it('Underscore is works', function() {
// just checking that _ works
expect(_.size([1,2,3])).toEqual(3);
});
it('List component is loaded', function(){
expect(List.test()).toBe('List Component');
});
});
});
List - it's my ReactJS component. And when I trying to run my tests, I'm got the error as result:
grunt test
