node assert/should.js/mocha/karma/Travis CI預習

node assert部分方法

assert(value[, message])
assert.ok(value[, message])
assert()是assert.ok()的簡寫方式，二者用法同樣。
若是value的值爲true，那麼什麼也不會發生。若是value爲false，將拋出一個信息爲message的錯誤。
assert.equal(actual, expected[, message])
判斷實際值(actual)與指望徝(expected)是否相等(==)，若是不相等，則拋出一個message的錯誤。

assert.deepEqual(actual, expected[, message])
deep意味着子對象的可枚舉屬性也會被計算進去。若是自己屬性及子對象屬性都相等時經過。不然會拋出錯誤。

assert.deepStrictEqual(actual, expected[, message])
判斷條件爲是否深度嚴格相等。
assert.notDeepEqual(actual, expected[, message])
assert.notDeepStrictEqual(actual, expected[, message])
assert.notEqual(actual, expected[, message])
assert.notStrictEqual(actual, expected[, message])
assert.strictEqual(actual, expected[, message])
assert.throws(block[, error][, message])複製代碼

should.js

 瞭解部分，基本寫法以下：

.true (===)

true.should.be.true;複製代碼

.false (!==)

false.should.be.false
(0).should.not.be.false複製代碼
