I tried enabling indicator tests:

Cbc.jl/test/MOI_wrapper.jl

Line 77 in 01ee423

"indicator1", "indicator2", "indicator3", "indicator4",

but it fails as Cbc believes the problem to be unbounded. The indicator constraints are bridged by the IndicatorSOS1Bridge into SOS1 constraints.
This issue seems to be due to the fact that the variables of the SOS1 constraints are not all binary.
This was reported upstream in coin-or/Cbc#363
