Integration test framework requires sorted data

[Licenser]

Problem

As part of the integration tets we only support textual comparisons, without understanding of the structure:

contains checks if a given string exists somewhere in the file

equals_file checks if the two files are identical

The problem arises that we produce structured data where equality isn't defined by textual comparison. For example the two JSON objects {"a":1,"b":2} and {"b":2,"a":1} are equal but not identical for textual comparison.

This limits us to either dictate the exact output or to only rely on non structured data to compare.

Possible Solution(s)

• A short term solution is the introduction of a json-sorted codec using our sorted_serialize function.
• A long term solution would be to introduce some asserts that allow analysis and logical comparison instead of textual one (tremor script for example ;)

Reclassifying this as a enhancement since the immediate problem is resolved by adding json-sorted
