失败我使用摩卡与chai.js为CoffeeScript的单元测试。我有一个咕task的任务来将咖啡文件编译到测试文件夹,并启动PhantomJS来运行摩卡测试。Chai.js不指定其断言在测试
一切正常,但是chai.js只能说明什么测试失败,什么是预期值和实际值,它没有指定什么说法并不传递一个测试用例。有没有什么好的方法可以打印断言或至少是失败断言的索引?我也打开chai.Assertion.includeStack
然而,只显示了JavaScript文件不是为CoffeeScript的测试,有帮助的行号。
FizzBuzzTest.coffee
fizz = new FizzBuzz()
describe "Print numbers from 1 to 100", ->
it "First 10 digits from 1 to 5", ->
result = fizz.do()
arr = result.split(fizz.Delimiter)
expect(arr[0]).to.equal("1")
expect(arr[1]).to.equal("2")
expect(arr[2]).to.equal(fizz.Fizz)
expect(arr[3]).to.equal("3") # this assertion should fail
expect(arr[4]).to.equal(fizz.Buzz)
执行测试
$ grunt test
Running "mocha:run" (mocha) task
Testing: Content/runner.html
Print numbers from 1 to 100
✓ First 10 digits from 1 to 5
1) Last 10 digits from 95 to 100
✓ Print FizzBuzz instead of number which is divisible by both 3 and 5
✓ Check number
✓ Check Fizz
✓ Check Buzz
✓ Check FizzBuzz
✓ Check if > 100 then null
✓ Check if < 1 then null
8 passing (113ms)
1 failing
1) Print numbers from 1 to 100 Last 10 digits from 95 to 100:
AssertionError: expected true to be false

问: 是否有设置chai.js来具体谈谈其中AssertionError的一个好办法发生了什么?
像:Asse田:预计真正是假符合预期(ARR [3])to.equal( “3”)
谢谢。
谢谢,这将做到这一点。如果chai.js可以自动添加断言(这里只是'false'),那会很好。 –
