/**
Test cases that ensure the inline examples in the jazzy guides compile.
To add an example:
1. Add a test case named in the form `testGuideName$ExampleName`.
2. Wrap the code you’d like to appear in the documentation within the
following comment blocks:
```
//#-example-code
...
//#-end-example-code
```
3. Insert a call to `guideExample()` where you’d like the example code to be
inserted in the guide’s Markdown.
```
<%- guideExample('GuideName', 'ExampleName', 'iOS') %>
```
4. Run `make darwin-style-code` to extract example code from the test method
below and insert it into the guide.
