Stylesheets and test

[jburel]

Add tests for each entry in the downgrade catalogs.

[jburel]

Some tests have been written already, add more as part of 4.4.x series.

It might be possible to also generate legacy samples from the same code using downgrades, each sample is not that complex but the test code necessary is quite verbose, legacy samples made this way would also not contain tests of old structures with no current equivalent

[jmoore]

For OMERO.tables, Simon created a gist using an older library to generate a test file which has old structures (keeping that explanation vague to show the parallel; see ​https://gist.github.com/4261679). It might be that we have to do something like this outside of the regular workflow. Obviously, having good test data is more critical than the complexity of the code, and I would argue we need the old structures.

[jburel]

Useful to have them as gist but yet another place to look at and very easy to miss/forget. It will be useful to have them somehow under openmicroscopy.

[ajpatterson]

So the idea would be to have the test shell out to run a command to make an old test file using a pre compiled jar? Then add a collection of old jars to git for the tests to use.

[jmoore]

jburel: yup, gists are not optimal. Do we need a repository per version?

ajpatterson: that would work except then we would have to have the old jars present to, which I worry about due to size.
