Beyond Coverage Mariano Anaya @rmarianoa
Test Coverage might be misleading
It’s not a quality metric
Just a reference
It’s necessary, but not sufficient
It can only tell about the code that is there...
...what about the missing code?
SQLite Library: 122.9 KLOC Tests: 91 596.1 KLOC (745x)
# of tests >> # of main source
None
Don’t rely on coverage.
Rely on thoughtful testing.
Thank You! @rmarianoa
