use yoga::Node;
use yoga::StyleUnit::{Auto, UndefinedValue};

fn main() {
	let mut node = Node::new();

Testing
-------
The unit tests are automatically generated based on upstream fixtures and should not be edited manually.

```
$ cargo test
```

To generate the test cases:
Download the [ChromeDriver](http://chromedriver.chromium.org) binary and put it somewhere in your `$PATH`. Linux/MacOS example:

```
$ cp chromedriver /usr/local/bin
```

Install the required Ruby gem.

```
$ sudo gem install watir
```

Generate the tests.

```
$ ruby gentest/gentest.rb
```
