What a title. Ugh.
I spent a while trying to figure out if there was a way that I could use should.js BDD-style asserts and have WebStorm’s integrated test runner understand the results. It appears that nodeunit is integrated nicely, but you have to write nodeunit tests. Here’s a little hack I came up with to let me use should.js:
var should = require('should');
var assertFn = should.Assertion.prototype.assert;
function describe(name, fn) {
exports[name] = function (testFn) {
should.Assertion.prototype.assert = function () {
testFn.doesNotThrow(Function.prototype.apply.bind(assertFn, this, arguments));
};
fn(testFn.expect);
testFn.done();
}
}
describe('foo', function () {
true.should.be.ok;
});
describe('bar', function () {
false.should.be.ok;
});
should.js extends Object with a number of items, but they all create a new Should.Assertion. Here, I’m creating a nodeunit-style function that wraps should.Assertion in a nodeunit test so that the counts and itemization come out right. Then I call the actual test code with test.expect as a parameter (for convenience), and all should-style assertions will go through the wrapper and get counted as nodeunit tests. Finally I call test.done() because, well, you’re s’posed to.
