------------------------------------------
Summary: Add a mechanism to provide integration tests with all
storage engines
Key: IGNITE-18481
URL: https://issues.apache.org/jira/browse/IGNITE-18481
Project: Ignite
Issue Type: Improvement
Reporter: Roman Puchkovskiy
Currently, if we want to test something for all storage engines that we
support, we hard-code the list of engines. This has a risk that, if we add a
new storage engine, we forget to add it to the list of tested engines, so it
remains untested.
Here are some ideas:
# Use service loaders to find the storage engines. This has a drawback of
implicitness, that is, if the mechanism fails to find an engine, we might miss
that unfortunate event, and some engine might become untested.
# Use a centrally-maintained hard-coded list of all storage engines. The
drawback is that we might forget to add a new engine.
# Combination of both. Add some automagic facilities that will find the
storage engines using service loaders (and supply them to tests), but also
maintain a hand-crafted list of all production storage engines, and add a test
that makes sure that the 2 mechanisms yield same results. This approach allows
us to use automagic, but also have explicitness of hard-coding.
