## Setting Up
### Installation
* To install all the dependencies run `npm install`.
* Then run `bower install` for `jasmine`, `jquery` and `underscore` library dependencies.
* Install grunt globally, which is a Javascript Task Runner `npm install -g grunt-cli`.
### Running Tests
* For testing, we use Jasmine.
* Tests are written in the `test/unit` folder. Each file in the `src` directory have different test cases files associataed with them in the `test/unit` directory. The majority of the test cases that test the library as a black box are in `dom-comparator.spec.js`.
* To run tests, run `grunt; testem server;` (from the root directory of the repository)
* To see the final outputs open http://localhost:7357/ in the browser, open the JavaScript console and look for the `final_results` array.
### Cases which don't work
* If there are multiple occurrences of a node in the DOM. For example:
> `nodeA`:
```html
```
> `nodeB`:
```html
ORIGINAL TEXT
```
> Here, since there are 2 occurrences of `ORIGINAL TEXT
` in `nodeB`, the exact match of it cannot be found in `nodeA`, due to which the resulted output is not as expected.
* When the wrapping of the original node is changed. For example:
> `nodeA`:
```html
```
> `nodeB`:
```html
```
> Here, since the wrapping of `nodeB` is changed (wrapped by ` ...
`), the whole content in `nodeB` would be considered as inserted (because matching heirarchy is top to bottom).
