I have been facing a puzzling situation with my test files. When I have only 'test1.js' present, Mocha reports that there are no tests passing, giving me a "0 passing" message. However, if both 'test1.js' and 'test2.js' are present and both depend on promises, once again, no tests run and Mocha reports the same "0 passing". Surprisingly, when I modify one of the tests to not use a promise, Mocha runs both tests successfully. What could be causing this strange behavior? Here are the files in question:
index.js:
require('./server').then( function(server) {
server.listen(8080, function() {
console.log("Started server");
});
);
server.js:
var express = require('express');
var server = express();
module.exports = new Promise((function(resolve, reject) {
return resolve(server);
}));
test1.spec.js:
require('./server').then(function(server) {
describe('Test Suite #1', function () {
it('should run test #1', function testSomething(done) {
return done();
});
});
});
test2.spec.js (using server.js as promise, tests do not run):
require('./server').then(function(server) {
describe('Test Suite #2', function () {
it('should run test #2', function testSomethingElse(done) {
return done();
});
});
});
test2.spec.js (server.js is not used as promise, both tests run):
var server = require('./server');
describe('Test Suite #2', function () {
it('should run test #2', function testSomethingElse(done) {
return done();
});
});
To execute these tests, make sure you have nodejs, Express, and Mocha installed, then run the following command:
% mocha "*.spec.*"
Although the examples provided here may not utilize the 'server' variable, in actual tests, a promise needs to be returned because sometimes 'server.js' accesses remote systems for configuration data. While I can find workarounds for this issue, any guidance or explanation regarding what is happening would be greatly appreciated!
