我有以下内容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(); }
    });

});

是这样的StringCalculator.specs.js

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);
            });
        });
    });
});

这就是它StringCalculator.js本身(来自 mocha 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;
        }
    }
});

在浏览器调用中运行规范时testrunner.html,一切都按预期工作。在 OS X 上运行mocha-phantomjs client/specs/testrunner.html时,我收到以下错误:

Failed to start mocha: Init timeout

我在这里可能缺少什么?

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

更新:如果我打电话,mocha-phantomjs http://localhost:81/client/specs/testrunner.html我还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

通过npm 包运行时,我遇到了同样的Failed to start mocha错误。在这里找到了解决方案。mocha-phantomjsgrunt-mocha-phantomjs

在此重复以供参考:

要使用 mocha-phantomjs 运行,请更改

mocha.run();

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

这个文件展示了如何使用它。

对我来说,NodeJS 0.10.x 似乎无法使用它。切换到 NodeJS 0.8.8 后,一切正常。

使用当前版本的 mocha-phantomjs 和 PhantomJS 现在一切正常。

感谢您提供此信息,我尝试了上述方法,但在浏览器中显示“mochaPhantomJS 未定义”失败。按照下面的快速调整,效果很好:

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