Question

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看起来像这样：

// 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就是这样：

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;
        }
    }
});

在调用testrunner.html的浏览器中运行规范时，一切都按预期工作。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

我在这里可能缺少什么？

我也尝试了mocha-phantomjs http://httpjs.herokuapp.com失败并出现同样的错误。

更新：如果我正在调用mocha-phantomjs http://localhost:81/client/specs/testrunner.html，我也会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

Answer 1

通过Failed to start mocha npm包运行mocha-phantomjs时，我遇到了同样的grunt-mocha-phantomjs错误。找到了解决方案here。

在此重复以供参考：

要使用mocha-phantomjs运行，请更改

mocha.run();

到

if (mochaPhantomJS) {
  mochaPhantomJS.run();
}
else {
  mocha.run();
}

Answer 2

This file展示了如何使用它。

~~对我来说，NodeJS 0.10.x似乎无法使用它。切换到NodeJS 0.8.8后，一切都按预期工作。~~

现在使用当前版本的mocha-phantomjs和PhantomJS一切正常。

Answer 3

感谢您提供此信息，我尝试了上述内容但在浏览器中失败了＆＃34; mochaPhantomJS未定义＆＃34;。根据下面的快速调整，它运作良好：

if(typeof(mochaPhantomJS)!=="undefined")
{
  mochaPhantomJS.run();
}
else
{
  mocha.run();
}

使用mocha-phantomjs进行mocha初始化超时
