Coverage of code run at precompile time

General Usage

Coverage doesn’t seem to capture lines which are executed only during package precompile time and not while actually running the tests. Is there a way to also track coverage for these lines?

In this example, the process function is incorrectly marked as missed, despite having indeed run at precompile time.

I’ve found a workaround to this problem:

  • Test on Travis/Appveyor with --compilecache=no; this runs the tests without precompilation so as to gather accurate coverage stats
  • Then add an extra line julia -e 'using Package' to test the precompilation itself

See

for an example of a fix to this problem.
