 what-is-a-test Message gives the name and height:

 Error: Expected 'is 34 inches tall' to include 'Susan'
  at assert (node_modules/expect/lib/assert.js:29:9)

您已了解如何阅读测试，现在该运行测试了。我们让它变得相当容易。在你现在用来编写 nodejs tests.js 或 nodejs index.js 的同一个终端中，你只需要编写 learn。就是这样！无论在哪个实验室，我们的 Learn 命令都会找出您的位置并运行适当的测试并为您提供结果。

说到结果...让我们谈谈如何阅读测试给出的结果。

如果我们现在在终端中运行 learn，你会得到一堆失败的测试。它看起来像这样：

  1) what-is-a-test Name returns "Susan":

      Error: Expected 'Joe' to equal 'Susan'
      + expected - actual

      -Joe
      +Susan

      at assert (node_modules/expect/lib/assert.js:29:9)
      at Expectation.toEqual (node_modules/expect/lib/Expectation.js:81:30)
      at Context.it (test/index-test.js:6:26)

  2) what-is-a-test Height is less than 40:
     Error: Expected 74 to be less than 40
      at assert (node_modules/expect/lib/assert.js:29:9)
      at Expectation.toBeLessThan (node_modules/expect/lib/Expectation.js:156:28)
      at Context.it (test/index-test.js:13:28)

  3) what-is-a-test Message gives the name and height:
     Error: Expected ' is 74 inches tall' to include 'Joe'
      at assert (node_modules/expect/lib/assert.js:29:9)
      at Expectation.toInclude (node_modules/expect/lib/Expectation.js:215:28)
      at Context.it (test/index-test.js:19:29)



npm ERR! Test failed.  See above for more details.
Let's break this down a bit. If you look at the line under the cat (I love programmers) you'll see a summary of how the tests went:

0 passing (612ms)
3 failing
