/**
 * Class for PHPUnit tests
 *
 * PaymentVAT is the class actually used by the core UI (compta/tva/card.php,
 * compta/paiement_vat.php) to record a payment against a Tva declaration - unlike
 * Tva::addPayment(), which is legacy/unused (see TvaTest.php). PaymentVAT::create() and
 * Tva::getSommePaiement() do agree on the same table/link (payment_vat.fk_tva).
 *
 * Note: like PaymentLoan (see PaymentLoanTest.php), PaymentVAT::create() does not use the
 * $fk_tva/$fk_typepaiement properties it cleans at the top of the method: its INSERT actually reads
 * $chid and $paiementtype (both left uncleaned), matching the real callers
 * (compta/tva/card.php, compta/paiement_vat.php).
 *
 * @backupGlobals disabled
 * @backupStaticAttributes enabled
 * @remarks	backupGlobals must be disabled to have db,conf,user and lang not erased.
