See attached report of test-coverage analysis in Undertow master branch.

The instruction coverage in Undertow packages vary from 0% to 94%, with an overall average of 66% coverage. The branches coverage vary from 0% to 100%, with an overall average of 55%. Notice that only a single package has 0% coverage (servlet.sse), all the others have some test coverage.

The goal of this Jira is to increase those numbers. Ideally, we would like to:

• increase the instruction coverage to 70% in all core packages
• increase the branch coverage to 60% in all core packages
• make sure every remaining package has a minimum of 60% instruction coverage and 50% branch coverage

Once this goal is achieved, we are going to work on incrementing this mark again for a future release.
