| [verify()](./case-boundary.iinvokecoretest.verify.md) | Call this to tell the ContractCase core to actually invoke the test.
Note that during verification, a failed verification doesn't return an error Result, but failed configuration or core bugs will. This is the intended default behaviour - as a failed verification doesn't necessarily indicate a problem in the code that is being verified.
