[英]Testing Angular with Mocha returning error
我使用以下方法安裝了Mocha和Shouldjs
npm install -g mocha
npm install -g should
測試我的Angular應用。 我從這里復制了一個測試,內容如下:
describe('addition', function () {
it('should add 1+1 correctly', function (done) {
var onePlusOne = 1 + 1;
onePlusOne.should.equal(2);
// must call done() so that mocha know that we are... done.
// Useful for async tests.
done();
});
});
但是,當我使用
mocha mytest.js
我收到此錯誤:
addition
1) should add 1+1 correctly
0 passing (7ms)
1 failing
1) addition should add 1+1 correctly:
TypeError: Cannot call method 'equal' of undefined

誰能看到該如何解決?
看一下文檔,他們似乎需要將原語包裝在()中才能正常工作:
https://github.com/shouldjs/should.js
var should = require('should');
(5).should.be.exactly(5).and.be.a.Number;
並且:
Should(5).be.exactly(5)
會工作。
因此,嘗試將代碼更改為:
(onePlusOne).should.equal(2);
