Generalised tests

[rieder]

Currently we have tests for all individual community codes. These replicate large portions of each other, especially codes in the same domain. It would be good to have generalised tests available that can run for all codes (within a domain). These could include basic tests (does a code initialise/stop/set parameters), but perhaps also sanity checks (is the result like expected). If this is possible, the latter of these should probably not result in "hard" fails, but in warnings (e.g. "do not use this code for this kind of problem"). Alternatively, the test could be overridden by a specific code test, or ignored for a specific code.
