javascript 如何从 karma runner 套件中获取通过测试的列表？

How can I get a list of passing tests from karma runner suite?

提问by Amit Erandole

When I run karma on my webapp, I only get generic messages like tests passed - is there a way to get a list of passing tests? How do I get more verbose output?

当我在我的 web 应用程序上运行 karma 时，我只会收到类似测试通过的通用消息 - 有没有办法获取通过测试的列表？如何获得更详细的输出？

I cannot find this anywhere in the documentation.

我在文档中的任何地方都找不到这个。

I know how this can be done!

我知道如何做到这一点！

Karma's terminal output comes from objects called Reporters. Karma ships with some built-in Reporters (they can be found in karma/lib/reporters). Karma is also able to use custom Reporters.

Karma 的终端输出来自称为 Reporters 的对象。Karma 附带了一些内置的 Reporters（它们可以在 中找到karma/lib/reporters）。Karma 还可以使用自定义 Reporters。

You can specify which reporters are used in your project's karma.config.jsfile.

您可以指定在您的项目karma.config.js文件中使用哪些报告器。

For example, the 'dots' reporter just prints a dot when each test passes:

例如，'dots' 报告器在每次测试通过时只打印一个点：

reporters: ['dots'],

The 'progress' reporter prints more than dots:

“进步”记者打印的不仅仅是点：

reporters: ['progress'],

The custom reporter karma-spec-reporterprints the name of each test when the test succeeds or fails (but not much else):

自定义报告器karma-spec-reporter在测试成功或失败时打印每个测试的名称（但没有其他太多）：

reporters: ['spec'],

You may want to roll your own reporter, since karma-junit-reporter, karma-spec-reporter, and the included reporters may not meet your needs.

您可能想要滚动自己的记者，因为 karma-junit-reporter、karma-spec-reporter 和包含的记者可能无法满足您的需求。

I am guessing that customizing karma-spec-reporter is the best option in this case, since it already prints a line when a test succeeds.

我猜在这种情况下自定义 karma-spec-reporter 是最好的选择，因为它在测试成功时已经打印了一行。

If you are looking for something even more simple to work from, hereis a custom reporter that I built. It reports passing and failing tests with no terminal colors.

如果您正在寻找更简单的工作方式，这里是我构建的自定义报告器。它报告通过和失败的测试，没有终端颜色。

      suppressErrorSummary: true,  // do not print error summary
      suppressFailed: false,  // do not print information about failed tests
      suppressPassed: false,  // do not print information about passed tests
      suppressSkipped: true,  // do not print information about skipped tests
      showSpecTiming: false // print the time elapsed for each spec
    },
    plugins: ["karma-spec-reporter"],
