||
|
expect('test').to.have.ownPropertyDescriptor('length');
|
||
|
expect('test').to.have.ownPropertyDescriptor('length', { enumerable: false, configurable: false, writable: false, value: 4 });
|
||
|
expect('test').not.to.have.ownPropertyDescriptor('length', { enumerable: false, configurable: false, writable: false, value: 3 });
|
||
|
expect('test').ownPropertyDescriptor('length').to.have.property('enumerable', false);
|
||
|
expect('test').ownPropertyDescriptor('length').to.have.keys('value');
|

## 2.0.0 / 2015-02-09
|
||
|
|
||
|
Unfortunately with 1.10.0 - compatibility broke with older versions because of
|
||
|
the `addChainableNoop`. This change has been reverted.
|
||
|
|
||
|
Any plugins using `addChainableNoop` should cease to do so.
|
||
|
|
||
|
Any developers wishing for this behaviour can use [dirty-chai](https://www.npmjs.com/package/dirty-chai)

|
### Noop Function for Terminating Assertion Properties
|
||
|
|
||
|
The following assertions can now also be used in the function-call form:
|
||
|
|
||
|
* ok
|
||
|
* true
|
||
|
* false
|
||
|
* null
|
||
|
* undefined
|
||
|
* exist
|
||
|
* empty
|
||
|
* arguments
|
||
|
* Arguments
|
||
|
|
||
|
The above list of assertions are property getters that assert immediately on
|
||
|
access. Because of that, they were written to be used by terminating the assertion
|
||
|
chain with a property access.
|
||
|
|
||
|
```js
|
||
|
expect(true).to.be.true;
|
||
|
foo.should.be.ok;
|
||
|
```
|
||
|
|
||
|
This syntax is definitely aesthetically pleasing but, if you are linting your
|
||
|
test code, your linter will complain with an error something like "Expected an
|
||
|
assignment or function call and instead saw an expression." Since the linter
|
||
|
doesn't know about the property getter it assumes this line has no side-effects,
|
||
|
and throws a warning in case you made a mistake.
|
||
|
|
||
|
Squelching these errors is not a good solution as test code is getting to be
|
||
|
just as important as, if not more than, production code. Catching syntactical
|
||
|
errors in tests using static analysis is a great tool to help make sure that your
|
||
|
tests are well-defined and free of typos.
|
||
|
|
||
|
A better option was to provide a function-call form for these assertions so that
|
||
|
the code's intent is more clear and the linters stop complaining about something
|
||
|
looking off. This form is added in addition to the existing property access form
|
||
|
and does not impact existing test code.
|
||
|
|
||
|
```js
|
||
|
expect(true).to.be.true();
|
||
|
foo.should.be.ok();
|
||
|
```
|
||
|
|
||
|
These forms can also be mixed in any way, these are all functionally identical:
|
||
|
|
||
|
```js
|
||
|
expect(true).to.be.true.and.not.false();
|
||
|
expect(true).to.be.true().and.not.false;
|
||
|
expect(true).to.be.true.and.not.false;
|
||
|
```
|
||
|
|
||
|
#### Plugin Authors
|
||
|
|
||
|
If you would like to provide this function-call form for your terminating assertion
|
||
|
properties, there is a new function to register these types of asserts. Instead
|
||
|
of using `addProperty` to register terminating assertions, simply use `addChainableNoop`
|
||
|
instead; the arguments to both are identical. The latter will make the assertion
|
||
|
available in both the attribute and function-call forms and should have no impact
|
||
|
on existing users of your plugin.

||

## 1.9.1 / 2014-03-19
|
||
|
|
||
|
The following changes are required if you are upgrading from the previous version:
|
||
|
|
||
|
- **Users:**
|
||
|
- Migrate configuration options to new interface. (see notes)
|
||
|
- **Plugin Developers:**
|
||
|
- No changes required
|
||
|
- **Core Contributors:**
|
||
|
- Refresh `node_modules` folder for updated dependencies.
|
||
|
|
||
|
### Configuration
|
||
|
|
||
|
There have been requests for changes and additions to the configuration mechanisms
|
||
|
and their impact in the Chai architecture. As such, we have decoupled the
|
||
|
configuration from the `Assertion` constructor. This not only allows for centralized
|
||
|
configuration, but will allow us to shift the responsibility from the `Assertion`
|
||
|
constructor to the `assert` interface in future releases.
|
||
|
|
||
|
These changes have been implemented in a non-breaking way, but a depretiation
|
||
|
warning will be presented to users until they migrate. The old config method will
|
||
|
be removed in either `v1.11.0` or `v2.0.0`, whichever comes first.
|
||
|
|
||
|
#### Quick Migration
|
||
|
|
||
|
```js
|
||
|
// change this:
|
||
|
chai.Assertion.includeStack = true;
|
||
|
chai.Assertion.showDiff = false;
|
||
|
|
||
|
// ... to this:
|
||
|
chai.config.includeStack = true;
|
||
|
chai.config.showDiff = false;
|
||
|
```
|
||
|
|
||
|
#### All Config Options
|
||
|
|
||
|
##### config.includeStack
|
||
|
|
||
|
- **@param** _{Boolean}_
|
||
|
- **@default** `false`
|
||
|
|
||
|
User configurable property, influences whether stack trace is included in
|
||
|
Assertion error message. Default of `false` suppresses stack trace in the error
|
||
|
message.
|
||
|
|
||
|
##### config.showDiff
|
||
|
|
||
|
- **@param** _{Boolean}_
|
||
|
- **@default** `true`
|
||
|
|
||
|
User configurable property, influences whether or not the `showDiff` flag
|
||
|
should be included in the thrown AssertionErrors. `false` will always be `false`;
|
||
|
`true` will be true when the assertion has requested a diff be shown.
|
||
|
|
||
|
##### config.truncateThreshold **(NEW)**
|
||
|
|
||
|
- **@param** _{Number}_
|
||
|
- **@default** `40`
|
||
|
|
||
|
User configurable property, sets length threshold for actual and expected values
|
||
|
in assertion errors. If this threshold is exceeded, the value is truncated.
|
||
|
|
||
|
Set it to zero if you want to disable truncating altogether.
|
||
|
|
||
|
```js
|
||
|
chai.config.truncateThreshold = 0; // disable truncating
|
||
|
```

|
### Browserify
|
||
|
|
||
|
This is a small patch that updates the dependency tree so browserify users can install
|
||
|
chai. (Remove conditional requires)
|
||
|
|
||
|
## 1.8.0 / 2013-09-18
|
||
|
|
||
|
The following changes are required if you are upgrading from the previous version:
|
||
|
|
||
|
- **Users:**
|
||
|
- See `deep.equal` notes.
|
||
|
- **Plugin Developers:**
|
||
|
- No changes required
|
||
|

||
|

|
||
|
|
||
|
### Deep Equals
|
||
|
|
||
|
This version of Chai focused on a overhaul to the deep equal utility. The code for this
|
||
|
tool has been removed from the core lib and can now be found at:
|
||
|
[chai / deep-eql](https://github.com/chaijs/deep-eql). As stated in previous releases,
|
||
|
this is part of a larger initiative to provide transparency, independent testing, and coverage for
|
||
|
some of the more complicated internal tools.
|
||
|
|
||
|
For the most part `.deep.equal` will behave the same as it has. However, in order to provide a
|
||
|
consistent ruleset across all types being tested, the following changes have been made and _might_
|
||
|
require changes to your tests.
|
||
|
|
||
|
**1.** Strict equality for non-traversable nodes according to [egal](http://wiki.ecmascript.org/doku.php?id=harmony:egal).
|
||
|
|
||
|
_Previously:_ Non-traversable equal via `===`.
|
||
|
|
||
|
```js
|
||
|
expect(NaN).to.deep.equal(NaN);
|
||
|
expect(-0).to.not.deep.equal(+0);
|
||
|
```
|
||
|
|
||
|
**2.** Arguments are not Arrays (and all types must be equal):
|
||
|
|
||
|
_Previously:_ Some crazy nonsense that led to empty arrays deep equaling empty objects deep equaling dates.
|
||
|
|
||
|
```js
|
||
|
expect(arguments).to.not.deep.equal([]);
|
||
|
expect(Array.prototype.slice.call(arguments)).to.deep.equal([]);
|
||
|
```
|
||
|
|
||
|
- [#156](https://github.com/chaijs/chai/issues/156) Empty object is eql to empty array
|
||
|
- [#192](https://github.com/chaijs/chai/issues/192) empty object is eql to a Date object
|
||
|
- [#194](https://github.com/chaijs/chai/issues/194) refactor deep-equal utility
|
||
|
|
||
|
### CI and Browser Testing
|
||
|
|
||
|
Chai now runs the browser CI suite using [Karma](http://karma-runner.github.io/) directed at
|
||
|
[SauceLabs](https://saucelabs.com/). This means we get to know where our browser support stands...
|
||
|
and we get a cool badge:
|
||
|
|
||
|
[![Selenium Test Status](https://saucelabs.com/browser-matrix/logicalparadox.svg)](https://saucelabs.com/u/logicalparadox)
|
||
|
|
||
|
Look for the list of browsers/versions to expand over the coming releases.

## 1.7.2 / 2013-06-27
|
||
|
|
||
|
The following changes are required if you are upgrading from the previous version:
|

|
|
||
|

|
||
|
|
||
|
### Coverage Reporting
|
||
|
|
||
|
Coverage reporting has always been available for core-developers but the data has never been published
|
||
|
for our end users. In our ongoing effort to improve accountability this data will now be published via
|
||
|
the [coveralls.io](https://coveralls.io/) service. A badge has been added to the README and the full report
|
||
|
can be viewed online at the [chai coveralls project](https://coveralls.io/r/chaijs/chai). Furthermore, PRs
|
||
|
will receive automated messages indicating how their PR impacts test coverage. This service is tied to TravisCI.
|
||
|
|
||
|
### Other Fixes
|
||
|
|
||
|
- [#175](https://github.com/chaijs/chai/issues/175) Add `bower.json`. (Fix ignore all)
|
||
|

|
|
||
|
### Official Bower Support
|
||
|
|
||
|
Support has been added for the Bower Package Manager ([bower.io])(http://bower.io/). Though
|
||
|
Chai could be installed via Bower in the past, this update adds official support via the `bower.json`
|
||
|
specification file.
|
||
|
|
||
|
- [#175](https://github.com/chaijs/chai/issues/175) Add `bower.json`.
|
||
|
|
||
|
## 1.7.0 / 2013-06-17
|
||
|
|
||
|
The following changes are required if you are upgrading from the previous version:
|
||
|
|
||
|
- **Users:**
|
||
|
- No changes required.
|
||
|
- **Plugin Developers:**
|
||
|

|
||
|
- **Core Contributors:**
|
||
|
- Refresh `node_modules` folder for updated dependencies.
|
||
|
|
||
|
### AssertionError Update Notice
|
||
|
|
||
|
Chai now uses [chaijs/assertion-error](https://github.com/chaijs/assertion-error) instead an internal
|
||
|
constructor. This will allow for further iteration/experimentation of the AssertionError constructor
|
||
|
independant of Chai. Future plans include stack parsing for callsite support.
|
||
|
|
||
|
This update constructor has a different constructor param signature that conforms more with the standard
|
||
|
`Error` object. If your plugin throws and `AssertionError` directly you will need to update your plugin
|
||
|
with the new signature.
|
||
|
|
||
|
```js
|
||
|
var AssertionError = require('chai').AssertionError;
|
||
|
|
||
|
/**
|
||
|
* previous
|
||
|
*
|
||
|
* @param {Object} options
|
||
|
*/
|
||
|
|
||
|
throw new AssertionError({
|
||
|
message: 'An assertion error occurred'
|
||
|
, actual: actual
|
||
|
, expect: expect
|
||
|
, startStackFunction: arguments.callee
|
||
|
, showStack: true
|
||
|
});
|
||
|
|
||
|
/**
|
||
|
* new
|
||
|
*
|
||
|
* @param {String} message
|
||
|
* @param {Object} options
|
||
|
* @param {Function} start stack function
|
||
|
*/
|
||
|
|
||
|
throw new AssertionError('An assertion error occurred', {
|
||
|
actual: actual
|
||
|
, expect: expect
|
||
|
, showStack: true
|
||
|
}, arguments.callee);
|
||
|
|
||
|
// other signatures
|
||
|
throw new AssertionError('An assertion error occurred');
|
||
|
throw new AssertionError('An assertion error occurred', null, arguments.callee);
|
||
|
```
|
||
|
|
||
|
#### External Dependencies
|
||
|
|
||
|
This is the first non-developement dependency for Chai. As Chai continues to evolve we will begin adding
|
||
|
more; the next will likely be improved type detection and deep equality. With Chai's userbase continually growing
|
||
|
there is an higher need for accountability and documentation. External dependencies will allow us to iterate and
|
||
|
test on features independent from our interfaces.
|
||
|
|
||
|
Note: The browser packaged version `chai.js` will ALWAYS contain all dependencies needed to run Chai.

### Deep Equality
|
||
|
|

|
they silently passed for all scenarios. Thanks to [@katsgeorgeek](https://github.com/katsgeorgeek) for the contribution.

### New Assertions
|
||
|
|
||
|
#### Array Members Inclusion
|
||
|
|
||
|
Asserts that the target is a superset of `set`, or that the target and `set` have the same members.
|
||
|
Order is not taken into account. Thanks to [@NickHeiner](https://github.com/NickHeiner) for the contribution.
|
||
|
|
||
|
```js
|
||
|
// (expect/should) full set
|
||
|
expect([4, 2]).to.have.members([2, 4]);
|
||
|
expect([5, 2]).to.not.have.members([5, 2, 1]);
|
||
|
|
||
|
// (expect/should) inclusion
|
||
|
expect([1, 2, 3]).to.include.members([3, 2]);
|
||
|
expect([1, 2, 3]).to.not.include.members([3, 2, 8]);
|
||
|
|
||
|
// (assert) full set
|
||
|
assert.sameMembers([ 1, 2, 3 ], [ 2, 1, 3 ], 'same members');
|
||
|
|
||
|
// (assert) inclusion
|
||
|
assert.includeMembers([ 1, 2, 3 ], [ 2, 1 ], 'include members');
|
||
|
|
||
|
```
|
||
|
|
||
|
#### Non-inclusion for Assert Interface
|
||
|
|
||
|
Most `assert` functions have a negative version, like `instanceOf()` has a corresponding `notInstaceOf()`.
|
||
|
However `include()` did not have a corresponding `notInclude()`. This has been added.
|
||
|
|
||
|
```js
|
||
|
assert.notInclude([ 1, 2, 3 ], 8);
|
||
|
assert.notInclude('foobar', 'baz');
|
||
|
```

### Migration Requirements
|
||
|
|
||
|
The following changes are required if you are upgrading from the previous version:
|
||
|
|
||
|
- **Users:**
|
||
|
- _Update [2013-02-04]:_ Some users may notice a small subset of deep equality assertions will no longer pass. This is the result of
|
||
|
[#120](https://github.com/chaijs/chai/issues/120), an improvement to our deep equality algorithm. Users will need to revise their assertions
|
||
|
to be more granular should this occur. Further information: [#139](https://github.com/chaijs/chai/issues/139).
|
||
|

### Other Bug Fixes
|
||
|
|
||
|
- Improve type detection of `.a()`/`.an()` to work in cross-browser scenarios.
|
||
|
- [#116](https://github.com/chaijs/chai/issues/116): `.throw()` has cleaner display of errors when WebKit browsers.
|
||
|
- [#120](https://github.com/chaijs/chai/issues/120): `.eql()` now works to compare dom nodes in browsers.
|
||
|
|
||
|
|
||
|
### Usage Updates
|
||
|
|
||
|
#### For Users
|
||
|
|
||
|
**1. Component Support:** Chai now included the proper configuration to be installed as a
|
||
|
[component](https://github.com/component/component). Component users are encouraged to consult
|
||
|
[chaijs.com](http://chaijs.com) for the latest version number as using the master branch
|
||
|
does not gaurantee stability.
|
||
|
|
||
|
```js
|
||
|
// relevant component.json
|
||
|
devDependencies: {
|
||
|
"chaijs/chai": "1.5.0"
|
||
|
}
|
||
|
```
|
||
|
|
||
|
Alternatively, bleeding-edge is available:
|
||
|
|
||
|
$ component install chaijs/chai
|
||
|
|
||
|
**2. Configurable showDiff:** Some test runners (such as [mocha](http://visionmedia.github.com/mocha/))
|
||
|
include support for showing the diff of strings and objects when an equality error occurs. Chai has
|
||
|
already included support for this, however some users may not prefer this display behavior. To revert to
|
||
|
no diff display, the following configuration is available:
|
||
|
|
||
|
```js
|
||
|
chai.Assertion.showDiff = false; // diff output disabled
|
||
|
chai.Assertion.showDiff = true; // default, diff output enabled
|
||
|
```
|
||
|
|
||
|
#### For Plugin Developers
|
||
|
|
||
|
**1. New Utility - type**: The new utility `.type()` is available as a better implementation of `typeof`
|
||
|
that can be used cross-browser. It handles the inconsistencies of Array, `null`, and `undefined` detection.
|
||
|
|
||
|
- **@param** _{Mixed}_ object to detect type of
|
||
|
- **@return** _{String}_ object type
|
||
|
|
||
|
```js
|
||
|
chai.use(function (c, utils) {
|
||
|
// some examples
|
||
|
utils.type({}); // 'object'
|
||
|
utils.type(null); // `null'
|
||
|
utils.type(undefined); // `undefined`
|
||
|
utils.type([]); // `array`
|
||
|
});
|
||
|
```
|
||
|
|
||
|
#### For Core Contributors
|
||
|
|
||
|
**1. Browser Testing**: Browser testing of the `./chai.js` file is now available in the command line
|
||
|
via PhantomJS. `make test` and Travis-CI will now also rebuild and test `./chai.js`. Consequently, all
|
||
|
pull requests will now be browser tested in this way.
|
||
|
|
||
|
_Note: Contributors opening pull requests should still NOT include the browser build._
|
||
|
|
||
|
**2. SauceLabs Testing**: Early SauceLab support has been enabled with the file `./support/mocha-cloud.js`.
|
||
|
Those interested in trying it out should create a free [Open Sauce](https://saucelabs.com/signup/plan) account
|
||
|
and include their credentials in `./test/auth/sauce.json`.
