chaimel

chaimel

chai.js expect BDD api wrapped with camelCase method names instead of dot.chaining.style.

Lets you do:

• expect(error).toHaveProperty("message"); instead of
• expect(error).to.have.property("message");

Usage

var expect = require("chaimel");
expect(42).notToBeAbove(43);

Why?

dot.chaining.style is problematic for me because:

• It's out of convention with the standard JavaScript built-in method names
  • toLowerCase, indexOf, forEach, hasOwnProperty
• It's awkward to speak and hear. Do you say the "dot"s or just imply them?
• It doesn't work well with text editor autocomplete, whereas camelCase does
• I also personally find this kind of use of Object.defineProperty unidiomatic for the golden age of JavaScript. It's fully standard and fine, but my opinion is it fundamentally makes the language more magical and ruby-like and these are drawbacks not advantages.
• It was pretty quick and easy to create this module, so I did

Are all the chai.expect methods supported?

No, I left out abbreviations such as eql, lt gt because I hate abbreviations. Use the full words and use deepEqual instead of eql. Having both equal and eql with different semantics is error-prone, hard to remember, and confusing to read.

Browser Support

The code is designed to work in node.js or in the browser via browserify. If you want vanilla browser support, file and issue and I can add the neccessary boilerplate.
