问题描述

在试图弄清楚如何使某些 jasmine 期望语句依赖于先前的期望语句时，我发现在 Jasmine 2.3.0 之前，没有办法.(请参阅第一次期望失败后停止 jasmine 测试)但是，Jasmine 2.3.0 添加了一个选项 stopSpecOnExpectationFailure，当设置为 true 时，将在第一次失败时停止测试.

对这个前景感到兴奋，我修改了我的 conf.js 以包含该选项:

<代码>/** conf.js*/出口.config = {框架:'茉莉花'，规格:['search-spec.js']，使用AllAngular2AppRoots:真，茉莉花节点选择:{stopSpecOnExpectationFailure:真}};

但这对我不起作用.

在我的测试中，我有:

/*** 选择元素中的测试选项被选中*/功能验证选项选择(选项){var myEl = $('select[value="' + option + '"]';expect(myEl.isPresent()).toBe(true, 'Option, ' + option + ', 不是下拉列表中的值.(可能是文本.)');expect(myEl.isSelected()).toBe(true, 'Option, ' + option + ', 没有按预期选择.');}

在上面的代码中，将尝试两个期望语句，但如果第一个失败，我不需要尝试第二个.

你们中有人用茉莉花解决了这个问题吗?

(是的，我知道 jasmine-bail-fast 和 protractor-fail-fast.但是，在我看来，使用内置功能更好解决方案.)

根据我在 protractor 和 jasmine-npm (protractor 使用的 jasmine runner) 源码，不是加 这么简单配置中的 stopSpecOnExpectationFailure 或 stopOnFailure jasmine 节点选项.必须对 protractor 进行更改以支持新的 stopSpecOnExpectationFailure jasmine 节点选项.请在 Protractor 问题跟踪器中创建问题/功能请求.p>

我也试过调用throwOnExpectationFailure函数，在onPrepare中设置stopSpecOnExpectationFailure值 throw jasmine.getEnv()() 但这些都不起作用.也许，我遗漏了一些东西，并且有一种方法可以启用该设置.

While trying to figure out how to make certain jasmine expect statements dependent on a previous expect statement I discovered that previous to Jasmine 2.3.0, there was not a way. (see Stop jasmine test after first expect fails) However, Jasmine 2.3.0 added an option stopSpecOnExpectationFailure that when set to true will stop a test on the first failure.

Excited by this prospect, I modified my conf.js to include the option:

/*
 * conf.js
 */
exports.config = {
    framework: 'jasmine',
    specs: ['search-spec.js'],
    useAllAngular2AppRoots: true,
    jasmineNodeOpts: {
        stopSpecOnExpectationFailure: true
    }
};

But this did not work for me.

In my test, I have:

/**
 * Test option from select element is selected
 */
function verifyOptionSelected(option) {
   var myEl = $('select[value="' + option + '"]';

   expect(myEl.isPresent()).toBe(true, 'Option, ' + option + ', is not a value in the dropdown list. (It might be the text.)');

   expect(myEl.isSelected()).toBe(true, 'Option, ' + option + ', is not selected as expected.');
}

In the code above, both expect statements will be attempted, but I don't need the second to be attempted if the first fails.

Are there any of you who have figured this out with jasmine?

(Yes, I know about jasmine-bail-fast and protractor-fail-fast. However, in my opinion, using the built-in feature is a better solution.)

From what I see in the protractor and jasmine-npm (the jasmine runner that protractor uses) source code, it is not as simple as adding the stopSpecOnExpectationFailure or stopOnFailure jasmine node option to the configuration. There has to be changes applied to protractor to support the new stopSpecOnExpectationFailure jasmine node option. Please create an issue/feature request in Protractor issue tracker.

I've also tried to call the throwOnExpectationFailure function, set the stopSpecOnExpectationFailure value throw jasmine.getEnv() in onPrepare() but none of that worked. Perhaps, I am missing something and there is a way to enable the setting.
