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(从摩卡样本)：
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;
}
}
});
当在浏览器中调用testrunner.html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,会收到以下错误信息：
无法启动mocha：初始化超时
我可能在这里失踪？
我也试过mocha-phantomjs http://httpjs.herokuapp.com失败了同样的错误.
更新：
如果我打电话给mocha-phantomjs http：// localhost：81 / client / specs / testrunner.html我也在控制台上收到以下错误：
RangeError: Maximum call stack size exceeded. http://localhost:81/client/lib/chai.js?v=123423553533535:2601 Failed to start mocha: Init timeout
解决方法
我得到的一样通过grunt-mocha-phantomjs npm包运行mocha-phantomjs时,无法启动摩卡错误.找到解决方案
here.
重复参考：
要运行mocha-phantomjs,更改
mocha.run();
至
if (mochaPhantomJS) {
mochaPhantomJS.run();
}
else {
mocha.run();
}
