运行测试时出现错误消息？

Question

 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) at Expectation.toInclude (node_modules/expect/lib/Expectation.js:215:28) at Context.it (test/index-test.js:19:29)

I'm not sure what needs to be fixed. Please help.

Answer 1

You understand how to read tests, now it's time to run the tests. We've made it fairly easy. In the same terminal that you used to write nodejs tests.js or nodejs index.js now, you just need to write learn. That's it! No matter what the lab, our Learn command will figure out where you are and run the appropriate tests and give you results.

Speaking of results... let's talk about how to read the results that tests give you.

Reading Results of Tests

If we run learn in our terminal right now, you'll get a bunch of failed tests. It will look something like this:

Output from running learn in Terminal

  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
