Code coverage for PL/SQL

Question

Does anyone have tools or experience with code coverage for PL/SQL. I believe this is possible using DBMS_PROFILER?

Answer 1

http://www.toadworld.com/BLOGS/tabid/67/EntryID/267/Default.aspx has info about checking code coverage using the PL/SQL profiler.

Some helpful info about profiling on 9i or 10g is included in Metalink Article 243755.1 "Implementing and Using the PL/SQL Profiler" for information on profiling code. Grab the prof.zip from the bottom of the article, it has a profiler.sql which will nicely format your results after a profiling run.

More 10g documentation is available here without a MetaLinka account: http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14258/d_profil.htm

If you are running 11g there is a new Hierarchical Profiler documented here: http://download.oracle.com/docs/cd/B28359_01/appdev.111/b28424/adfns_profiler.htm

Answer 2

I found something useful on http://www.databasejournal.com/features/oracle/article.php/10893_2197231_3 page.

select exec.cnt/total.cnt * 100 "Code% coverage"
from  (select count(1) cnt
      from plsql_profiler_data d, plsql_profiler_units u
      where d.runid = &&runid
      and u.runid = d.runid
      and u.unit_number = d.unit_number
      and u.unit_name = upper('&&name')
      and u.unit_owner = upper('&&owner')
      ) total,
     (select count(1) cnt
      from plsql_profiler_data d, plsql_profiler_units u
      where d.runid = &&runid
      and u.runid = d.runid
      and u.unit_number = d.unit_number
      and u.unit_name = upper('&&name')
      and u.unit_owner = upper('&&owner')
      and d.total_occur > 0) exec;

Answer 3

Not sure if this is quite what you're after, but in 10g onwards there's a tool to do static PL/SQL code analysis.

Info here... http://www.psoug.org/reference/plsql_warnings.html

Note that it can be enabled at either session or database level.

In my experience it's thrown up quite a few false negatives so far.

Answer 4

There is a package you can install called DBMS_profiler. With this, you can start a profile and Oracle will store data in special tables. Then stop the profile and report from those tables.

Answer 5

See SD Test Coverage Tools. We're about to release a PLSQL test coverage tool with the same capabilities as our other tools, including a GUI to display the results on top of your source code, and a generated coverage report that collects details on individual functions as well as rollups for packages.

EDIT 2/15/2011: PLSQL test coverage production tool is available.
