Oracle PRAGMA COVERAGE
Version 21c

General Information
Library Note Morgan's Library Page Header
Which has the higher priority in your organization: Deploying a new database or securing the ones you already have? Looking for a website, and resources, dedicated solely to securing Oracle databases? Check out DBSecWorx.
Purpose The COVERAGE pragma marks PL/SQL code which is infeasible to test for coverage.

The pragma marks a specific code section. Marking infeasible code improves the quality of coverage metrics used to assess how much testing has been achieved.

Unfortunately none of Oracle's documentation explains what "to test for coverage" means. We will update this page when we figure that out.

COVERAGE
Not Feasible

The code, at right, is from Oracle's documentation but reformatted for readability
PRAGMA COVERAGE (<NOT_FEASIBLE | NOT_FEASIBLE_START | NOT_FEASIBILE_END>);
DECLARE
 x PLS_INTEGER := 42;
 y PLS_INTEGER;
BEGIN
  IF (x > 0) THEN
    y :=2;
  ELSE
    PRAGMA COVERAGE('NOT_FEASIBLE'); -- 1
    z:=3;
  END IF;

  IF (y > 0) THEN
    z :=2;
  ELSE
    PRAGMA COVERAGE('NOT_FEASIBLE'); -- 2
    z :=3;
  END IF;
END;
