Example 1 with CoverageService

use of gov.cms.ab2d.coverage.service.CoverageService in project ab2d by CMSgov.

the class CoverageDriverImpl method verifyCoverage.

/**
 * Verify that coverage data cached in the database matches expected business requirements.
 *
 * Steps
 *      - List of all contracts that are active contracts
 *      - Check whether contracts have a coverage period for every month since the contract
 *          attested. If not, log issue and filter out because other checks do not apply.
 *          {@link CoveragePeriodsPresentCheck}
 *      - Get count of beneficiaries for every month for every contract
 *          - Check that there are no {@link CoverageNoDuplicatesCheck}
 *          - Check that every month for a contract has some enrollment except
 *              for the current month {@link CoveragePresentCheck}
 *          - Check that the coverage for a contract and month is from the latest
 *              successful search {@link CoverageUpToDateCheck}
 *          - Check that the coverage month to month has not changed drastically {@link CoverageStableCheck}
 *      - If there are any issues report all of those issues and fail
 *
 * @throws CoverageVerificationException if one or more violations of expected business level behavior are found
