[erlang-questions] Using test data with ct

[dun...@sfractal.com]

I'm building a rebar3 application and using ct to test it. I have a bunch of test files containing data (sample json) to use as part of testing. When it was just a few, I converted them to erlang terms, and used -define in .hrl files in the include directory. But that doesn't scale well nor make for easy configuration management. I'd prefer to store each json (for a particular test) in a file since those files already exist created by others for validation. Then the test could read the file, and use jsx to convert text to json for comparison within the test.

Where can I stick a bunch of files and then access them as part of test? I understand there is a data_dir. Is that the proper way to do it? Where in the tree do I put a file so it ends up in data_dir?

Hello,

CT has built support for it. Please check this tutorial
http://learnyousomeerlang.com/common-test-for-uncommon-tests

In the nutshell, you create a folder and store your file there mytest_SUTE_data

and you can access this files from SUITE:
Scenario = filename:join([?config(data_dir, Config), "my.json"]),

Best Regards,
Dmitry
