問題描述

我有一個使用 Karma+Jasmine 和 JSHint 的 Grunt 設置.每當我在我的規范文件上運行 JSHint 時，我都會收到一系列未定義"錯誤，其中大部分是 Jasmine 的內置函數.例如:

I've got a Grunt setup which uses Karma+Jasmine and JSHint. Whenever I run JSHint on my spec file, I get a series of "undefined" errors, most of which are for Jasmine's built-in functions. For example:

Running "jshint:test" (jshint) task

   js/main.spec.js
      3 |describe("loadMatrix()", function() {
         ^ 'describe' is not defined.
      4 |    it("should not assign a value if no arg is passed.", function() {
             ^ 'it' is not defined.

(我的規范要測試的 JS 文件中的變量和函數也有一些未定義的錯誤，但我不確定這是為什么，這可能是一個單獨的問題.)

(I also get some undefined errors for the variables and functions from the JS file that my spec is meant to test against, but I'm not sure why that is and it may be a separate issue.)

我的 Karma 配置文件中有 frameworks: [ "jasmine" ]，我沒有為 JSHint 設置任何全局變量，也沒有 .jshintrc 文件，因為我在 Grunt 中配置它.我曾嘗試將 Jasmine 的函數作為 JSHint 全局變量添加到我的 Gruntfile 中，但是將它們設置為 true 或 false 并沒有什么不同——錯誤仍然存??在JSHint 跑了.

My Karma config file has frameworks: [ "jasmine" ] in it, I don't have any globals set for JSHint, and I don't have a .jshintrc file since I'm configuring it in Grunt. I did try adding Jasmine's functions as JSHint globals in my Gruntfile at one point, but setting them as either true or false didn't make a difference—the errors still persisted when JSHint ran.

我錯過了什么?我似乎無法讓 JSHint 在我的規范文件中跳過對 Jasmine 函數的定義檢查.

What am I missing? I can't seem to do anything to get JSHint to skip definition checking for Jasmine's functions in my spec file.

推薦答案

MINOR CORRECTION - .jshintrc 文件中的 predef 周圍應該有".

MINOR CORRECTION - there should be "" around predef in the .jshintrc file.

通過將其添加到我的 Gruntfile.coffee 中的 jshint 選項來修復:

Fixed by adding this to the jshint options in my Gruntfile.coffee:

predef: [
    "jasmine"
    "describe"
    "xdescribe"
    "before"
    "beforeEach"
    "after"
    "afterEach"
    "it"
    "xit"
    "it"
    "inject"
    "expect"
    "spyOn"
]

.jshintrc:

"predef": [
    "jasmine",
    "describe",
    "xdescribe",
    "before",
    "beforeEach",
    "after",
    "afterEach",
    "it",
    "xit",
    "it",
    "inject",
    "expect",
    "spyOn",
]
