davcondev How to keep code coverage information accurate for as much of the time as possible?
I want to have accurate code coverage statistics continually, without degrading deployment times (all my deployments are via ANT, not change set). Based on some reading (see links below) I believe that:
- The most accurate code coverage is via manual apex test execution via GUI - but only if previous values are cleared out first
- Eclipse & Developer Console can't be trusted to accurately calculate and update the coverage statistics
- Deployments with runAllTests=true also accurately calculate the coverage statistics - but don't update them
- "Store Only Aggregated Code Coverage" is suggested to run tests faster - but this has no impact on deployment times because of the previous point
And based on this I believe the following is the best I can do:
- After every major deployment (including those with runAllTests=true), clear the code coverage, clear test history and manually run all tests.
- Don't bother setting Store Only Aggregated Code Coverage for deployments with runAllTests=true as this will make no difference to deployment time.
Is my thinking correct?

Thanks for the reply.
It looks like this code uses the Apex Test Runner? According to one of the posts I referenced, this is not considered reliable?
Also am I correct in thinking that coverage isn't updated in the org itself by this code and is only available in an emailed spreadsheet?
