[Tom Haddon]

Add basic charm testing for cassandra.

[Tom Haddon (mthaddon)]

Hi Stuart,

I'm looking for a review here of whether this is a sufficient basic test of "does the Cassandra charm install correctly". Over time we can flesh it out to be exercising more complicated use cases.

[Stuart Bishop (stub)]

This is a basic test installing Apache Cassandra 3.0. It will test that the units deploy without error.

It does not test that it actually works, which takes more effort. For this and testing alternative versions, it is worth wrapping the existing amulet tests with enough mojo to go through the CI systems.
