Why do arrays not compare the way other values do (e.g. 1==1) Numbers, strings, booleans, null, and undefined are values, and are compared as you might expect. 1 == 1, ‘a’ == ‘a’, and so on. The difference between === and == in the case of values is that == will attempt to perform type … Read more
I prefer to edit my .eslintrc and add mocha to env section: … “env”: { “commonjs”: true, “node”: true, “mocha”: true }, … this way my package.json file is kept clean, also vscode plugin for eslint understands it better
Did you know, that you just go into your launch config, put your cursor after or between your other configs and press ctrl–space to get a current, valid mocha config auto-generated? Which works perfectly fine for me. Including stopping at breakpoints. ( I also had a prior, now outdated one, that did no longer for … Read more
You don’t export anything in your app module. Try adding this to your app.js file: module.exports = server
What Mocha options are you using? Maybe it is something to do with reporter (-R) or ui (-ui) being used? console.log(msg); works fine during my test runs, though sometimes mixed in a little goofy. Presumably due to the async nature of the test run. Here are the options (mocha.opts) I’m using: –require should -R spec … Read more
I know an ugly way of doing it, just by increasing default timeout of Mocha from 2 seconds to 10 seconds this can be done by adding a flag –timeout 10000 in the test scripts i.e – package.json “scripts”: { “start”: “SET NODE_ENV=dev && node server.js”, “test”: “mocha –timeout 10000” }
Solved it with adding this to my .eslintrc: “import/no-extraneous-dependencies”: [“error”, {“devDependencies”: true}] [no-extraneous-dependencies] Add exceptions? #422 Based on this user’s reply: you could set the option devDependencies: true in an .eslintrc in your test folder: rules: import/no-extraneous-dependencies: [error, { devDependencies: true }] Then you’ll get reports of any packages referenced that are not included dependencies … Read more
Check out the rewire module. It allows you to get (and manipulate) private variables and functions within a module. So in your case the usage would be something like: var rewire = require(‘rewire’), foobar = rewire(‘./foobar’); // Bring your module in with rewire describe(“private_foobar1”, function() { // Use the special ‘__get__’ accessor to get your … Read more
Sinon provides this functionality through the use of Sandboxes, which can be used a couple ways: // manually create and restore the sandbox var sandbox; beforeEach(function () { sandbox = sinon.sandbox.create(); }); afterEach(function () { sandbox.restore(); }); it(‘should restore all mocks stubs and spies between tests’, function() { sandbox.stub(some, ‘method’); // note the use of … Read more
The issue is caused by this: .catch((error) => { assert.isNotOk(error,’Promise error’); done(); }); If the assertion fails, it will throw an error. This error will cause done() never to get called, because the code errored out before it. That’s what causes the timeout. The “Unhandled promise rejection” is also caused by the failed assertion, because … Read more
