在 Jasmine 1.3 中添加自定义匹配器 - 显示未定义

Question

我在 jasmine 1.3 中使用量角器，尝试使用示例 here

向我的规范添加自定义匹配器

    beforeEach(function () {
        utils.log("beforeEach");

        this.addMatchers({
            toBeGoofy: function (expected) {

                if (expected === undefined) {
                    expected = '';
                }
                var pass = this.actual.hyuk === "gawrsh" + expected;
                if (pass) {
                    this.message = "Expected " + this.actual + " not to be quite so goofy";
                } else {
                    this.message = "Expected " + this.actual + " to be goofy, but it was not very goofy";
                }

                return pass;
            },
        });
    });

请注意，我没有对他们的示例进行任何更改。在那之后，我尝试在 "it" 中使用它：

expect({ "hyuk": "j" }).toBeGoofy();

我得到一个错误：

TypeError: undefined is not a function

在匹配器使用的那一行.. 有帮助吗？

Answer 1

问题显然出在匹配器定义上。而不是：

if (pass) {
    this.message = "Expected " + this.actual + " not to be quite so goofy";
    } else {
    this.message = "Expected " + this.actual + " to be goofy, but it was not very goofy";
}

此消息应该是 2 条消息的数组，第一个用于传递，第二个用于 not.matcher，所以它应该是这样的：

this.message = function() {
    return [
        "Expected " + this.actual.hyuk + " to be gawrsh",
        "Expected " + this.actual.hyuk + " not to be gawrsh"
    ];
};
