使用mocha-phantomjs的mocha初始化超时
我有以下testrunner.html
<html>
<head>
<title>Specs</title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<link rel="stylesheet" href="/content/css/mocha.css" />
<script>
function assert(expr, msg) {
if (!expr) throw new Error(msg || 'failed');
}
</script>
<script src="/client/lib/require.js" type="text/javascript" data-main="/client/specs/_runner.js"></script>
</head>
<body>
<div id="mocha"></div>
</body>
</html>_runner.js如下所示：
// Configure RequireJS
require.config({
baseUrl: '/client',
urlArgs: "v=" + (new Date()).getTime()
});
// Require libraries
require(['require', 'lib/chai', 'lib/mocha'], function (require, chai) {
// Chai
assert = chai.assert;
should = chai.should();
expect = chai.expect;
// Mocha
mocha.setup('bdd');
// Require base tests before starting
require(['specs/stringcalculator.specs'], function (person) {
mocha.setup({ globals: ['hasCert'] });
// Start runner
if (window.mochaPhantomJS) {
mochaPhantomJS.run();
}
else { mocha.run(); }
});
});StringCalculator.specs.js是这样的：
define(['app/model/StringCalculator'], function () {
describe("StringCalculator", function () {
describe("when an empty string is passed in", function () {
it("returns 0", function () {
var result = StringCalculator.add("");
assert(result === 0);
});
});
describe("when a number is passed in", function () {
it("returns the number", function () {
var result = StringCalculator.add("2");
assert(result === 2);
});
});
describe("when string is passed in", function () {
it("returns NaN", function () {
var result = StringCalculator.add("a");
assert(isNaN(result));
});
});
describe("when '1,2' is passed in", function () {
it("returns 3", function () {
var result = StringCalculator.add("1,2");
assert(result === 3);
});
});
});
});这是StringCalculator.js本身(来自摩卡示例)：
define([], function() {
window.StringCalculator = StringCalculator = {
add: function(inputString) {
if (inputString === '') {
return 0;
}
var result = 0;
var inputStrings = inputString.split(',');
for (var i = 0; i < inputStrings.length; i++) {
result += parseInt(inputStrings[i]);
}
return result;
}
}
});在调用testrunner.html的浏览器中运行规范时，一切都按预期运行。在OS X上运行mocha-phantomjs client/specs/testrunner.html时，出现以下错误：
Failed to start mocha: Init timeout
这里我可能遗漏了什么？
我还尝试了mocha-phantomjs http://httpjs.herokuapp.com，它失败了，出现了相同的错误。
更新:如果我调用mocha-phantomjs http://localhost:81/client/specs/testrunner.html，控制台上也会出现以下错误：
RangeError: Maximum call stack size exceeded.
http://localhost:81/client/lib/chai.js?v=123423553533535:2601

当通过grunt-mocha-phantomjs npm包运行mocha-phantomjs时，我得到了相同的Failed to start mocha错误。找到解决方案here。
在这里重复一下以供参考：
要使用mocha-phantomjs运行，请更改
mocha.run();至
if (mochaPhantomJS) {
mochaPhantomJS.run();
}
else {
mocha.run();

感谢这些信息，我尝试了上面的方法，但在浏览器中显示"mochaPhantomJS is undefined“时失败了。一个快速调整，如下所示，它很好用：
if(typeof(mochaPhantomJS)!=="undefined")
{
mochaPhantomJS.run();
}
else
{
mocha.run();
