Summary of the pro

#23117 replaced asserts with the test framework's internal helpers (see https://github.com/bitcoin/bitcoin/blob/dccf3d25f9e78909eb7b3143e89a7c87fac25ab5/test/functional/test_framework/util.py#L47-L59) for a single test, in order to see the expected and failed values if such an assertion fails. The same should be done for all the remaining tests. Potential candidates can be found via

$ cd ./t
