Pattern summary
Automate metrics collection.

Category
Design

Context
This pattern allows you to collect metrics efficiently and reliably. If you just write disposable scripts you will not need it

Description
By automating metrics collection, your metrics will be more reliable because they will be collected consistently and will not be so easily biased as manually collected

Implementation
If your tool doesn’t support collecting metrics, consider implementing a TEST AUTOMATION FRAMEWORK.
Some suggestions what to collect with each test run:
  • Number of tests available
  • Number of tests executed
  • Number of tests passed
  • Number of tests failed (eventually classified by error severity)
  • Execution time
  • Date
  • SUT Release
You should also try to associate bug-fix information to your test run metrics. For instance:
  • Number of errors removed
  • Number of errors not yet removed
  • Number of retests
  • Number of tests failed after retest
  • Average time to remove an error

Possible problems
If possible keep track of which bugs were found with the test automation: it will help you retain support from management and testers
