chai

问题 I am using node, mocha, and chai for my application. I want to test that my returned results data property is the same "type of object" as one of my model objects (Very similar to chai's instance). I just want to confirm that the two objects have the same sets of property names. I am specifically not interested in the actual values of the properties. Let's say I have the model Person like below. I want to check that my results.data has all the same properties as the expected model does. So in

问题 While establishing the connection using socket Error: Timeout of 2000ms exceeded. For async tests and hooks, ensure "done( )" is called; if returning a Promise, ensure it resolves. Given below is the code reference of the same beforeEach(function(done) { var socketOptions = {}; var socket = io.connect("http://localhost:5000", socketOptions); socket.on('connect', function () { console.log('Connection Established'); setTimeout(done, 500); }); socket.on('error', function (err) { console.log(

问题 I am looking to make use of Chai-HTTP for some testing. Naturally I want to test more than my GETs however I seem to be hitting a major roadblock when attempting to make POSTs. In an attempt to figure out why my POSTs weren't working I began hitting them against a POST test server. Here is a POST attempt formatted using an entirely different toolchain (Jasmine-Node and Frisby) for testing (that works just fine): frisby.create('LOGIN') .post('http://posttestserver.com/post.php', { grant_type:

问题 I am trying evaluate whether data returned from a table (table.getData()) which is a 2D array contains another array.

问题 I am new to unit testing Node.js application.

问题 I'm struggling with writing a test assertion using chai, mocha, and JS-DOM. I have a simple function like: function HtmlElement(el) { this.element = (el instanceof HTMLElement) ? el :document.createElement(el); } in the tests I have: it('should have addClass method', function () { const ul = (new HtmlElement('ul')); ul.element.should.be.equals('<ul></ul>'); // Outputs the actual UL }); but the error: AssertionError: expected <ul></ul> to equal '<ul></ul>' is the one I can't understand - what
