# Jasmine Core 2.0 Release Notes

## Summary

These notes are for Jasmine Core 2.0.

## Breaking Changes

The [`introduction.js`][intro] page covers the current syntax, highlighting the changes. Here are the known interface changes that are not backwards compatible with 1.x.

* New syntax for asynchronous specs
* New syntax for spies
* New interface for reporters
* Better Equality testing
* Replaced custom matchers for ease of use
* Change to `toThrow` matcher
* Clock now remains installed when a spec finishes
* More Jasmine internal variables/functions have been moved into closures

### New syntax for asynchronous specs

Similar to [Mocha][mocha], Jasmine `before`s, `spec`s, and `after`s can take an optional `done` callback in order to force asynchronous tests. The next function, whether it's a `before`, `spec` or `after`, will wait until this function is called or until a timeout is reached.

### New syntax for spies

Spies have a slightly modified syntax. The idea came from a desire to preserve any of the properties on a spied-upon function and some better testing patterns.

### New interface for reporters

The reporter interface has been **replaced**. The callbacks are different and more consistent. The objects passed in should only provide what is needed to report results. This enforces an interface to result data so custom reporters will be less coupled to the Jasmine implementation. The Jasmine reporter API now includes a slot for a `timer` object.

### Better Equality testing

We removed the previous equality code and are now using new code for testing equality. We started with [Underscore.js][underscore]'s `isEqual`, refactored a bit and added some additional tests.

### Replaced custom matchers for ease of use

The interface for adding custom matchers has been **replaced**. It has always been possible to add custom matchers, but the API was barely documented and difficult to test. We've changed how matchers are added and tested. Jasmine adds its own matchers by the same mechanism that custom matchers use. Dogfooding FTW.

### Change to `toThrow` matcher

We've changed the behavior of the `toThrow` matcher, moving some functionality to the `toThrowError` matcher. This should allow more of the requested use cases.

### Clock now remains installed when a spec finishes

After installing the Jasmine Clock, it will stay installed until `uninstall` is called -- clearing up any ambiguity for when those timing functions will revert to using the global clock object.

## More Jasmine internal variables/functions have been moved into closures

Certain variables/functions like a function to get the next spec id have been moved into closures, making the Jasmine interface cleaner.

## Other Changes

* Massive refactoring and better testing
* Environment setup now in `boot.js`
* Development and Build moved to Grunt
* Changes to how Jasmine is loaded
* Changes to how Jasmine is tested
* Better node.js support
* Better Continuous Integration Environment at Travis
* Support matrix updated
* Removed JsDoc Pages
* Adding Code Climate for JavaScript

## Massive refactoring and better testing

This is the biggest set of changes. We've touched nearly every file and every object. We've merged objects together and factored out code. We styled the code more consistently. We've improved nearly every test.

In general, Jasmine is made of smaller, more-loosely-coupled objects, unit-tested with explicit dependencies injected. This made tests easier to read, write, and maintain. We know this has made Jasmine development easier for the core team. We expect (and hope) this makes it easier for the community to extend Jasmine and provide pull requests that make more sense the first time out.

## Environment setup now in `boot.js`

Instantiation and setup of the Jasmine environment, including building reporters, exposing the "global" functions, and executing tests has moved into its own file: `boot.js`. This should make it easier to add custom reporters, configure some objects, or just in general change how you use Jasmine from the outside.

For example, during development, Jasmine uses its own `devboot.js` to load itself twice - once from `jasmine.js` and once from the source directories.

## Development and Build moved to Grunt

We've moved away from Ruby and embraced [Node.js][node] and [Grunt.js][grunt] for the various command line tasks during development. Yes, it's a just a different set of dependencies. But it's less code for the team to maintain - it turns out that JavaScript tools are pretty good at building JavaScript projects. This will make it easier for the community to make sure contributions work in browsers and in Node.js before submitting Pull Requests. There is more detail in the [Contributor's Guide][contrib].

## Changes to how Jasmine is loaded

We did not want to add new run-time dependencies, yet we needed to be cleaner when loading Jasmine. So we wrote a custom "require" scheme that works in Node.js and in browsers. This only affects pull requests which add files - please be careful in these cases. Again, the [Contributor's Guide][contrib] should help.

## Changes to how Jasmine is tested with Jasmine

Writing a custom require system helped enforce self-testing - the built `jasmine.js` testing Jasmine from the source directories. Overall this has improved the stability of the code. When you look at Jasmine's tests, you'll see both `jasmine` and `j$` used. The former, `jasmine`, will always be used to test the code from source, which is loaded into the reference `j$`. Please adhere to this pattern when writing tests for contributions.

## Better node.js support

`Node.js` is now officially a first-class citizen. For a long time we've made sure tests were green in Node before releasing. But it is now officially part of Jasmine's CI build at [Travis][travis]. For the curious, the [`node_suite.js`][node_suite], is essentially a `boot.js` for Node. An official `npm` is coming.

## Better Continuous Integration Environment at Travis

The [CI build at Travis][travis_jasmine] now runs the core specs in a build matrix across browsers. It's far from complete on the operating system matrix, but you will see that Jasmine runs against: Firefox, Chrome, Safari 5, Safari 6, [Phantom.js][phantom], [Node.js][node], and IE versions 8, 9, and 10. Big thanks to [SauceLabs][sauce] for their support of open source projects. We will happily take pull requests for additional OS/Browser combos within the matrix.

## Support Matrix Updated

We're dropping support for IE < 8. [Jasmine 1.x][jasmine_downloads] remains for projects that need to support older browsers.

## Removed JsDoc Pages

Comments in code are lies waiting to happen. Jasmine's JsDoc comments were no exception. The comments were out of date, the generated pages were even more out of date, and frankly they were not helpful. So they're gone.

Last year saw the posting of the [`introduction.js`][intro] page to document the real, practical interface for projects to use. This page has received a lot of positive feedback so expect more pages like this one.

## Adding Code Climate for JavaScript

We are running Code Climate for Jasmine. We have some work to do here but it's helping us easily find code hotspots.
