While this poll is primarily aimed gathering information from Perl programmers, feel free to answer it if you use a different language. That being said, if you're using an XUnit framework, "number of tests" means, in this context "number of asserts" (in other words, a test method with three asserts would count as 3 tests, not one).
In the comments below, feel free to explain any answers, particularly if not all of your tests pass.
Does your primary code base have a test suite?
If you answered "no" to the above question, please explain why (150 chars)
How many tests are in the largest test suite you work with?
How long does the aforementioned test suite take to run?
What percentage of your code is covered (rounding down)?
Do all tests pass?
If you answered "no" to the above question, what percentage of your tests fail?
What is the primary language the test suite is in?
What test framework the test suite is based on? (e.g. Perl is probably Test::Harness and Java is often jUnit)
