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

assert(value[, message])
assert.ok(value[, message])
assert()是assert.ok()的简写方式，两者用法一样。
如果value的值为true，那么什么也不会发生。如果value为false，将抛出一个信息为message的错误。
assert.equal(actual, expected[, message])
判断实际值(actual)与期望徝(expected)是否相等(==)，如果不相等，则抛出一个message的错误。

assert.deepEqual(actual, expected[, message])
deep意味着子对象的可枚举属性也会被计算进去。如果本身属性及子对象属性都相等时通过。否则会抛出错误。

assert.deepStrictEqual(actual, expected[, message])
判断条件为是否深度严格相等。
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])

should.js

 了解部分，基本写法如下：

.true (===)

true.should.be.true;

.false (!==)

false.should.be.false
(0).should.not.be.false
