base_testclass
Archive testing is divided up loosely into pre-entity (e.g. test_entity_store and test_base) and post-entity testing (e.g. this file). Of course test_base has entities but they are more for the purpose of validating name setting.
This class imports a minimal archive file created in antelope_utilities to contain a multioutput, nontrivial process (USLCI petroleum refining) and an intermediate process (a grid mix). These don't do anything special but the refinery process can test both exchange generation / allocation and lcia.
Subclass this to access that archive. Current uses:
