Code executed by exec excluded from coverage #380
Description
Originally reported by mb2297 (Bitbucket: mb2297, GitHub: Unknown)
It might be unrealistic to expect this to work, but python files that are read and then executed with exec (or with execfile) aren't counted towards the coverage report.
Example:
#!python
# impl.py
def foo():
print "foo"
def bar():
print "bar"
#!python
# impl2.py
print "the answer to life, the universe and everything is: {}".format(undeclared_var)
#!python
# test.py
from impl import foo
foo()
namespace = {
'undeclared_var': 42
}
with open('impl2.py') as f:
code = compile(f.read(), 'impl2.py', 'exec')
exec(code, globals(), namespace)
Results in the following on both OS X and Ubuntu:
$ coverage run --source . test.py
foo
the answer to life, the universe and everything is: 42
$ coverage report
