16 test.py [-aBbcdDfgGhLmprtTuv] [modfilter [testfilter]]
18 Test harness.
20 -a level
21 --all
22 Run the tests at the given level. Any test at a level at or below this is
23 run, any test at a level above this is not run. Level 0 runs all tests.
24 The default is to run tests at level 1. --all is a shortcut for -a 0.
26 -b
27 --build
28 Run "python setup.py build" before running tests, where "python"
29 is the version of python used to run test.py. Highly recommended.
30 Tests will be run from the build directory. (Note: In Python < 2.3
31 the -q flag is added to the setup.py command line.)
33 -B
34 Run "python setup.py build_ext -i" before running tests. Tests will be
35 run from the source directory.
37 -c use pychecker
39 -d
40 Instead of the normal test harness, run a debug version which
41 doesn't catch any exceptions. This is occasionally handy when the
42 unittest code catching the exception doesn't work right.
43 Unfortunately, the debug harness doesn't print the name of the
44 test, so Use With Care.
46 --dir directory
47 Option to limit where tests are searched for. This is
48 important when you *really* want to limit the code that gets run.
49 For example, if refactoring interfaces, you don't want to see the way
50 you have broken setups for tests in other packages. You *just* want to
51 run the interface tests.
53 -D
54 Works like -d, except that it loads pdb when an exception occurs.
56 -f
57 Run functional tests instead of unit tests.
59 -g threshold
60 Set the garbage collector generation0 threshold. This can be used to
61 stress memory and gc correctness. Some crashes are only reproducible when
62 the threshold is set to 1 (agressive garbage collection). Do "-g 0" to
63 disable garbage collection altogether.
65 -G gc_option
66 Set the garbage collection debugging flags. The argument must be one
67 of the DEBUG_ flags defined bythe Python gc module. Multiple options
68 can be specified by using "-G OPTION1 -G OPTION2."
70 --libdir test_root
71 Search for tests starting in the specified start directory
72 (useful for testing components being developed outside the main
73 "src" or "build" trees).
75 --keepbytecode
76 Do not delete all stale bytecode before running tests
78 -L
79 Keep running the selected tests in a loop. You may experience
80 memory leakage.
82 -t
83 Time the individual tests and print a list of the top 50, sorted from
84 longest to shortest.
86 -p
87 Show running progress. It can be combined with -v or -vv.
89 -r
90 Look for refcount problems.
91 This requires that Python was built --with-pydebug.
93 -T
94 Use the trace module from Python for code coverage. XXX This only works
95 if trace.py is explicitly added to PYTHONPATH. The current utility writes
96 coverage files to a directory named `coverage' that is parallel to
97 `build'. It also prints a summary to stdout.
99 -v
100 Verbose output. With one -v, unittest prints a dot (".") for each test
101 run. With -vv, unittest prints the name of each test (for some definition
102 of "name" ...). With no -v, unittest is silent until the end of the run,
103 except when errors occur.
105 When -p is also specified, the meaning of -v is sligtly changed. With
106 -p and no -v only the percent indicator is displayed. With -p and -v
107 the test name of the current test is shown to the right of the percent
108 indicator. With -p and -vv the test name is not truncated to fit into
109 80 columns and it is not cleared after the test finishes.
111 -u
112 -m
113 Use the PyUnit GUI instead of output to the command line. The GUI imports
114 tests on its own, taking care to reload all dependencies on each run. The
115 debug (-d), verbose (-v), progress (-p), and Loop (-L) options will be
116 ignored. The testfilter filter is also not applied.
118 -m starts the gui minimized. Double-clicking the progress bar will start
119 the import and run all tests.
122 modfilter
123 testfilter
124 Case-sensitive regexps to limit which tests are run, used in search
125 (not match) mode.
126 In an extension of Python regexp notation, a leading "!" is stripped
127 and causes the sense of the remaining regexp to be negated (so "!bc"
128 matches any string that does not match "bc", and vice versa).
129 By default these act like ".", i.e. nothing is excluded.
131 modfilter is applied to a test file's path, starting at "build" and
132 including (OS-dependent) path separators.
134 testfilter is applied to the (method) name of the unittest methods
135 contained in the test files whose paths modfilter matched.
137 Extreme (yet useful) examples:
139 test.py -vvb . "^testWriteClient$"
141 Builds the project silently, then runs unittest in verbose mode on all
142 tests whose names are precisely "testWriteClient". Useful when
143 debugging a specific test.
145 test.py -vvb . "!^testWriteClient$"
147 As before, but runs all tests whose names aren't precisely
148 "testWriteClient". Useful to avoid a specific failing test you don't
149 want to deal with just yet.
151 test.py -m . "!^testWriteClient$"
153 As before, but now opens up a minimized PyUnit GUI window (only showing
154 the progress bar). Useful for refactoring runs where you continually want
155 to make sure all tests still pass.
