- Hi. I am looking for any references to empirical work on the effectiveness
- of partial code coverage. Are there any studies that:
-
- - look at typical amounts of code coverage (.e.g., "test suites typically
- cover 90% of the statements and 80% of the branches of the tested
- program"), or
-
- - relate code coverage to error discovery or failure rates (e.g.,
- "exercising 85% of the branches led to a failure rate of X per 1000
- lines of code")?
-
- I know that there is no theoretical basis for claiming that more code coverage
- leads to more error discovery; what I am looking for is any evidence that it
- works (or doesn't work) in practice. Anecdotes are fun, but I'd really prefer
- references to conference or journal papers. Thank you.
