This is our testing framework.

|
||
|
|
Goals:
|
||
|
|
|
||
|
|
* it should be compatible with py.test and operate very similarly
|
||
|
|
(or identically)
|
||
|
|
* does not require any external dependencies
|
||
|
|
* preferably all the functionality should be in this file only
|
||
|
|
* no magic, just import the test file and execute the test functions, that's it
|
||
|
|
* portable

"""
|
||
|
|
Run a function in a Python subprocess with hash randomization enabled.
|
||
|
|
|
||
|
|
If hash randomization is not supported by the version of Python given, it
|
||
|
|
returns False. Otherwise, it returns the exit value of the command. The
|
||
|
|
function is passed to sys.exit(), so the return value of the function will
|
||
|
|
be the return value.
|
||
|
|
|
||
|
|
The environment variable PYTHONHASHSEED is used to seed Python's hash
|
||
|
|
randomization. If it is set, this function will return False, because
|
||
|
|
starting a new subprocess is unnecessary in that case. If it is not set,
|
||
|
|
one is set at random, and the tests are run. Note that if this
|
||
|
|
environment variable is set when Python starts, hash randomization is
|
||
|
|
automatically enabled. To force a subprocess to be created even if
|
||
|
|
PYTHONHASHSEED is set, pass ``force=True``. This flag will not force a
|
||
|
|
subprocess in Python versions that do not support hash randomization (see
|
||
|
|
below), because those versions of Python do not support the ``-R`` flag.
|
||
|
|
|
||
|
|
``function`` should be a string name of a function that is importable from
|
||
|
|
the module ``module``, like "_test". The default for ``module`` is
|
||
|
|
"sympy.testing.runtests". ``function_args`` and ``function_kwargs``
|
||
|
|
should be a repr-able tuple and dict, respectively. The default Python
|
||
|
|
command is sys.executable, which is the currently running Python command.
|
||
|
|
|
||
|
|
This function is necessary because the seed for hash randomization must be
|
||
|
|
set by the environment variable before Python starts. Hence, in order to
|
||
|
|
use a predetermined seed for tests, we must start Python in a separate
|
||
|
|
subprocess.
|
||
|
|
|
||
|
|
Hash randomization was added in the minor Python versions 2.6.8, 2.7.3,
|
||
|
|
3.1.5, and 3.2.3, and is enabled by default in all Python versions after
|
||
|
|
and including 3.3.0.

Run all tests:
|
||
|
|
|
||
|
|
>>> sympy.test() # doctest: +SKIP
|
||
|
|
|

|
||
|
|
>>> sympy.test("_basic") # doctest: +SKIP
|
||
|
|
|
||
|
|
Run all tests in sympy/functions/ and some particular file:
|
||
|
|
|
||
|
|
>>> sympy.test("sympy/core/tests/test_basic.py",
|
||
|
|
... "sympy/functions") # doctest: +SKIP
|
||
|
|
|
||
|
|
Run all tests in sympy/core and sympy/utilities:
|
||
|
|
|
||
|
|
>>> sympy.test("/core", "/util") # doctest: +SKIP
|
||
|
|
|
||
|
|
Run specific test from a file:
|
||
|
|
|
||
|
|
>>> sympy.test("sympy/core/tests/test_basic.py",
|
||
|
|
... kw="test_equality") # doctest: +SKIP
|
||
|
|
|
||
|
|
Run specific test from any file:
|
||
|
|
|
||
|
|
>>> sympy.test(kw="subs") # doctest: +SKIP
|
||
|
|
|
||
|
|
Run the tests with verbose mode on:
|
||
|
|
|
||
|
|
>>> sympy.test(verbose=True) # doctest: +SKIP
|
||
|
|
|
||
|
|
Do not sort the test output:
|
||
|
|
|
||
|
|
>>> sympy.test(sort=False) # doctest: +SKIP
|
||
|
|
|
||
|
|
Turn on post-mortem pdb:
|
||
|
|
|
||
|
|
>>> sympy.test(pdb=True) # doctest: +SKIP
|
||
|
|
|
||
|
|
Turn off colors:
|
||
|
|
|
||
|
|
>>> sympy.test(colors=False) # doctest: +SKIP
|
||
|
|
|
||
|
|
Force colors, even when the output is not to a terminal (this is useful,
|
||
|
|
e.g., if you are piping to ``less -r`` and you still want colors)
|
||
|
|
|
||
|
|
>>> sympy.test(force_colors=False) # doctest: +SKIP
|
||
|
|
|
||
|
|
The traceback verboseness can be set to "short" or "no" (default is
|
||
|
|
"short")
|
||
|
|
|
||
|
|
>>> sympy.test(tb='no') # doctest: +SKIP
|
||
|
|
|
||
|
|
The ``split`` option can be passed to split the test run into parts. The
|
||
|
|
split currently only splits the test files, though this may change in the
|
||
|
|
future. ``split`` should be a string of the form 'a/b', which will run
|
||
|
|
part ``a`` of ``b``. For instance, to run the first half of the test suite:
|
||
|
|
|
||
|
|
>>> sympy.test(split='1/2') # doctest: +SKIP
|
||
|
|
|
||
|
|
The ``time_balance`` option can be passed in conjunction with ``split``.
|
||
|
|
If ``time_balance=True`` (the default for ``sympy.test``), SymPy will attempt
|
||
|
|
to split the tests such that each split takes equal time. This heuristic
|
||
|
|
for balancing is based on pre-recorded test data.
|
||
|
|
|
||
|
|
>>> sympy.test(split='1/2', time_balance=True) # doctest: +SKIP
|
||
|
|
|
||
|
|
You can disable running the tests in a separate subprocess using
|
||
|
|
``subprocess=False``. This is done to support seeding hash randomization,
|
||
|
|
which is enabled by default in the Python versions where it is supported.
|
||
|
|
If subprocess=False, hash randomization is enabled/disabled according to
|
||
|
|
whether it has been enabled or not in the calling Python process.
|
||
|
|
However, even if it is enabled, the seed cannot be printed unless it is
|
||
|
|
called from a new Python process.
|
||
|
|
|
||
|
|
Hash randomization was added in the minor Python versions 2.6.8, 2.7.3,
|
||
|
|
3.1.5, and 3.2.3, and is enabled by default in all Python versions after
|
||
|
|
and including 3.3.0.
|
||
|
|
|
||
|
|
If hash randomization is not supported ``subprocess=False`` is used
|
||
|
|
automatically.
|
||
|
|
|
||
|
|
>>> sympy.test(subprocess=False) # doctest: +SKIP
|
||
|
|
|
||
|
|
To set the hash randomization seed, set the environment variable
|
||
|
|
``PYTHONHASHSEED`` before running the tests. This can be done from within
|
||
|
|
Python using
|
||
|
|
|
||
|
|
>>> import os
|
||
|
|
>>> os.environ['PYTHONHASHSEED'] = '42' # doctest: +SKIP
|
||
|
|
|
||
|
|
Or from the command line using
|
||
|
|
|
||
|
|
$ PYTHONHASHSEED=42 ./bin/test
|
||
|
|
|
||
|
|
If the seed is not set, a random seed will be chosen.
|
||
|
|
|
||
|
|
Note that to reproduce the same hash values, you must use both the same seed
|
||
|
|
as well as the same architecture (32-bit vs. 64-bit).

Optional keyword arg ``module_relative`` specifies how filenames
|
||
|
|
should be interpreted:
|
||
|
|
|
||
|
|
- If ``module_relative`` is True (the default), then ``filename``
|
||
|
|
specifies a module-relative path. By default, this path is
|
||
|
|
relative to the calling module's directory; but if the
|
||
|
|
``package`` argument is specified, then it is relative to that
|
||
|
|
package. To ensure os-independence, ``filename`` should use
|
||
|
|
"/" characters to separate path segments, and should not
|
||
|
|
be an absolute path (i.e., it may not begin with "/").
|
||
|
|
|
||
|
|
- If ``module_relative`` is False, then ``filename`` specifies an
|
||
|
|
os-specific path. The path may be absolute or relative (to
|
||
|
|
the current working directory).
|
||
|
|
|
||
|
|
Optional keyword arg ``name`` gives the name of the test; by default
|
||
|
|
use the file's basename.
|
||
|
|
|
||
|
|
Optional keyword argument ``package`` is a Python package or the
|
||
|
|
name of a Python package whose directory should be used as the
|
||
|
|
base directory for a module relative filename. If no package is
|
||
|
|
specified, then the calling module's directory is used as the base
|
||
|
|
directory for module relative filenames. It is an error to
|
||
|
|
specify ``package`` if ``module_relative`` is False.
|
||
|
|
|
||
|
|
Optional keyword arg ``globs`` gives a dict to be used as the globals
|
||
|
|
when executing examples; by default, use {}. A copy of this dict
|
||
|
|
is actually used for each docstring, so that each docstring's
|
||
|
|
examples start with a clean slate.
|
||
|
|
|
||
|
|
Optional keyword arg ``extraglobs`` gives a dictionary that should be
|
||
|
|
merged into the globals that are used to execute examples. By
|
||
|
|
default, no extra globals are used.
|
||
|
|
|
||
|
|
Optional keyword arg ``verbose`` prints lots of stuff if true, prints
|
||
|
|
only failures if false; by default, it's true iff "-v" is in sys.argv.
|
||
|
|
|
||
|
|
Optional keyword arg ``report`` prints a summary at the end when true,
|
||
|
|
else prints nothing at the end. In verbose mode, the summary is
|
||
|
|
detailed, else very brief (in fact, empty if all tests passed).
|
||
|
|
|
||
|
|
Optional keyword arg ``optionflags`` or's together module constants,
|
||
|
|
and defaults to 0. Possible values (see the docs for details):
|
||
|
|
|
||
|
|
- DONT_ACCEPT_TRUE_FOR_1
|
||
|
|
- DONT_ACCEPT_BLANKLINE
|
||
|
|
- NORMALIZE_WHITESPACE
|

|
|
- ELLIPSIS
|

- SKIP

- REPORT_UDIFF

- REPORT_CDIFF
|
||
|
|
- REPORT_NDIFF
|
||
|
|
- REPORT_ONLY_FIRST_FAILURE
|
||
|
|
|
||
|
|
Optional keyword arg ``raise_on_error`` raises an exception on the
|
||
|
|
first unexpected exception or failure. This allows failures to be
|
||
|
|
post-mortem debugged.
|
||
|
|
|
||
|
|
Optional keyword arg ``parser`` specifies a DocTestParser (or
|
||
|
|
subclass) that should be used to extract tests from the files.
|
||
|
|
|
||
|
|
Optional keyword arg ``encoding`` specifies an encoding that should
|
||
|
|
be used to convert the file to unicode.
|
||
|
|
|
||
|
|
Advanced tomfoolery: testmod runs methods of a local instance of
|

|
class doctest.Tester, then merges the results into (or creates)
|
||
|
|
global Tester instance doctest.master. Methods of doctest.master
|
||
|
|
can be called directly too, if you want to do something unusual.
|
||
|
|
Passing report=0 to testmod is especially useful then, to delay
|
||
|
|
displaying a summary. Invoke doctest.master.summarize(verbose)
|
||
|
|
when you're done fiddling.
