Generate test expectations for the Markua parser
In every earlier test-case we created the Markua input file manually and then we created the expected DOM in JSON representation also manually.
When we implemented the parsing and testing of Markua resources we ran the tests first and then took the dump of the error message and used that to create the JSON representation of both the DOM and the error report. It was a bit of unnecessary manual work. After all we could convert the generated DOM to JSON. Look at it to verify that we really want that to be the expected results and then save it as the expected JSON.
How can we make this easier?
Test coverage report with Devel::Cover for the Markua Parser
Coveralls indicates a test coverage of 96.88%, but it does not seem to take in account the branch and conditional coverage cases.
Let's see what does Devel::Cover on its own can tell us.

Markua resources: Include files
The next Markua element we'd like to be able to parse are used to include files. The same format can be used to include text files in various format (e.g. Perl, Python, YAML, etc.) or images. They are all called resources.
The format looks like this.
