我尝试在节点中使用测试工具 mocha。考虑以下测试场景
var requirejs = require('requirejs');
requirejs.config({
//Pass the top-level main.js/index.js require
//function to requirejs so that node modules
//are loaded relative to the top-level JS file.
nodeRequire: require
});
describe('Testing controller', function () {
it('Should be pass', function (done) {
(4).should.equal(4);
done();
});
it('Should avoid name king', function (done) {
requirejs(['../server/libs/validate_name'], function (validateName) {
var err_test, accountExists_test, notAllow_test, available_test;
validateName('anu', function (err, accountExists, notAllow, available) {
accountExists.should.not.be.true;
done();
});
});
});
});
作为测试结果,我得到了:
$ make test
./node_modules/.bin/mocha \
--reporter list
. Testing controller Should be pass: 0ms
1) Testing controller Should avoid name anu
1 passing (560 ms)
1 failing
1) Testing controller Should avoid name anu:
Uncaught TypeError: Cannot read property 'should' of null

第一遍没有任何复杂性,但第二遍似乎无法附加模块 shouldjs。为什么?
