Profiling
 
2
=========
 
3
 
 
4
The testrunner includes the ability to profile the test execution with hotshot
 
5
via the --profile option.

    >>> import os.path, sys
 
8
    >>> directory_with_tests = os.path.join(this_directory, 'testrunner-ex')
 
9
    >>> sys.path.append(directory_with_tests)
 
10
 
 
11
    >>> defaults = [
 
12
    ...     '--path', directory_with_tests,
 
13
    ...     '--tests-pattern', '^sampletestsf?$',
 
14
    ...     ]
 
15
 
 
16
    >>> sys.argv = [testrunner_script, '--profile=hotshot']
 
17
 
 
18
When the tests are run, we get profiling output.

    >>> from zope.testing import testrunner
 
21
    >>> testrunner.run_internal(defaults)

Profiling also works across layers.

    >>> sys.argv = [testrunner_script, '-ssample2', '--profile=hotshot',

42
The testrunner creates temnporary files containing hotshot profiler
 
43
data:
 
44
 
 
45
    >>> import glob
 
46
    >>> files = list(glob.glob('tests_profile.*.prof'))
 
47
    >>> files.sort()
 
48
    >>> files
 
49
    ['tests_profile.cZj2jt.prof', 'tests_profile.yHD-so.prof']
 
50
 
 
51
It deletes these when rerun.  We'll delete these ourselves:
 
52
 
 
53
    >>> import os
 
54
    >>> for f in files:
 
55
    ...     os.unlink(f)
