我正在尝试让用 Mocha 编写的测试来运行 Karma,它们有点工作,但是我不能使用 done() 方法来实现异步测试,这实际上使这些工具对我来说毫无用处。我错过了什么?
业力.conf.js
module.exports = function(config) {
config.set({
basePath: '../..',
frameworks: ['mocha', 'requirejs', 'qunit'],
client: {
mocha: {
ui: 'bdd'
}
},
files: [
{pattern: 'libs/**/*.js', included: false},
{pattern: 'src/**/*.js', included: false},
{pattern: 'tests/mocha/mocha.js', included: false},
{pattern: 'tests/should/should.js', included: false},
{pattern: 'tests/**/*Spec.js', included: false},
'tests/karma/test-main.js'
],
exclude: [
'src/main.js'
],
// test results reporter to use
// possible values: 'dots', 'progress', 'junit', 'growl', 'coverage'
reporters: ['progress', 'dots'],
port: 9876,
colors: true,
// possible values: config.LOG_DISABLE || config.LOG_ERROR || config.LOG_WARN || config.LOG_INFO || config.LOG_DEBUG
logLevel: config.LOG_WARN,
autoWatch: true,
// Start these browsers, currently available:

// - Firefox
// - Opera (has to be installed with `npm install karma-opera-launcher`)
// - Safari (only Mac; has to be installed with `npm install karma-safari-launcher`)
// - PhantomJS
// - IE (only Windows; has to be installed with `npm install karma-ie-launcher`)
browsers: ['Chrome'],
// If browser does not capture in given timeout [ms], kill it
captureTimeout: 60000,
// Continuous Integration mode
// if true, it capture browsers, run tests and exit
singleRun: false
});
};
test-main.js(配置 RequireJS)
var allTestFiles = [];
var pathToModule = function(path) {
return path.replace(/^\/base\//, '../').replace(/\.js$/, '');
};
Object.keys(window.__karma__.files).forEach(function(file) {
if (/Spec\.js$/.test(file)) {
// Normalize paths to RequireJS module names.
allTestFiles.push(pathToModule(file));
}
});
require.config({
// Karma serves files under /base, which is the basePath from your config file
baseUrl: '/base/src',
paths: {
'should': '../tests/should/should',
'mocha': '../tests/mocha/mocha',
'pubsub': '../libs/pubsub/pubsub',
'jquery': '../libs/jquery/jquery-1.10.2',
'jquery-mobile': '//code.jquery.com/mobile/1.4.2/jquery.mobile-1.4.2.min'
},
// dynamically load all test files
deps: allTestFiles,
// we have to kickoff jasmine, as it is asynchronous
callback: window.__karma__.start
});
测试/fooSpec.js
define(['music/note'], function(Note) {
describe('nothing', function(done) {
it('a silly test', function() {
var note = new Note;
note.should.not.eql(32);
});
done();
});
...
虽然这是一个人为的例子,但如果我删除 done() 调用,它就会成功。事实上,我得到:
Uncaught TypeError: undefined is not a function
at /Library/WebServer/Documents/vg/tests/mocha/fooSpec.js:8
这是 done() 行。如何/为什么没有定义?我不明白在哪里配置 Mocha(或使用什么选项)。是否存在某种全局命名空间或元编程魔法导致 RequireJS 干扰 Mocha?
我正在 OS X 10.9.2 上的 Chrome 33 中运行测试,以防万一。我已经为此浪费了大量时间,并准备放弃自动化测试:(——与 QUnit/Karma/RequireJS 有类似的砖墙,并且无法找到任何替代方法来成功地自动化测试。我觉得一个白痴。
