You should look into sections that cover test activity in the CEM.
(5.8, 6.8, 7.9, 8.9)

For EAL4 this would be the following.
8.9.2 Evaluation of Coverage (ATE_COV.2)
8.9.3 Evaluation of Depth (ATE_DPT.1)
8.9.4 Evaluation of Functional tests (ATE_FUN.1)
8.9.5 Evaluation of Independent testing (ATE_IND.2)

The evaluation of the test relys on the developer test documentation
(test plan, test procedure, expected results...which is not disclosed).

It is rather a matter of proving that the Target Of Evaluation (TOE)
adequately protects the Asset.

I would not want to spend US$1,000,000,000,000,000,000 to
protect my wallet (which has about $20 in it right now).

On the other hand I hope the US government spends whatever
is needed to protect the IT system for a nuclear missile
launch system.

So, it should suffice to prove that the security functions
can not be circumvented by an threat agent described in the ST.
