In order to make all tests running smoothly, the policy files should keep up with the default ima tcb policy. Especially ima_violations.sh expects to have a func=FILE_CHECK with mask=MAY_WRITE to trigger open writer and ToMtoU violations. Unfortunately, if ima_policy.sh which would change the system IMA policy ran before ima_violations.sh, ima_violations.sh would fail for sure because its prerequisite is broken.
