PHPUnit combine asserts

If you have to use assert OR assert and allow one faillure , and NOT 2:

        $failures = [];
        try {
            $this->assertNotEmpty( $body_obj->kamer_van_koophandel );
        } catch( Exception $e) {
            $failures[] = $e->getMessage();
        }
        try {
            $this->assertNotEmpty( $body_obj->leverancier->extern_id );
        } catch( Exception $e) {
            $failures[] = $e->getMessage();
        }
        if( count( $failures ) == 2 ) {
            throw new Exception (
                count($failures)." assertions failed:\n\t".implode("\n\t", $failures)
                );
        }
