There seems to be a package to enable this functionality, but I have no luck with it in python 3.5.2, or 2.7.12:
from ipython_doctester import test
@test
def my_fun():
'''
>>> 2 + 3
6
'''
pass
TypeError: data must be a dict, got: 'ipython_doctester'
Is it possible to run a doctest from a jupyter cell using this package or some other way?
I've looked at %doctest_mode also, and I see that it turns Doctest mode off and on, but have been unable to run an actual doctest from a cell.
Try this on Jupyter notebook:
def my_fun():
'''
>>> 2 + 3
6
'''
pass
import doctest
doctest.testmod()
The result should be:
**********************************************************************
File "__main__", line 3, in __main__.my_fun
Failed example:
2 + 3
Expected:
6
Got:
5
**********************************************************************
1 items had failures:
1 of 1 in __main__.my_fun
***Test Failed*** 1 failures.
TestResults(failed=1, attempted=3)
(I used python 2.7.12)
I keep hitting this page, but wanted to run a test for a single function. In that instance, the answer at https://stackoverflow.com/a/10081450/741316 helps. Namely:
def my_fun():
'''
>>> 2 + 3
6
'''
pass
import doctest
doctest.run_docstring_examples(my_fun, globals())
I used @pelson's answer to write this decorator
import doctest
import copy
import functools
def test(func):
globs = copy.copy(globals())
globs.update({func.__name__:func})
doctest.run_docstring_examples(func, globs, verbose=True, name=func.__name__)
return func
See a gist with a doctest:https://gist.github.com/2torus/f78b7cef5770927a92e3ca652f38ff89
You can use nbqa to run doctests in notebooks:
$ nbqa doctest my_notebook.ipynb
**********************************************************************
File "my_notebook.ipynb", cell_2:11, in my_notebook.add
Failed example:
add(2, 2)
Expected:
4
Got:
5
**********************************************************************
1 items had failures:
1 of 2 in my_notebook.hello
***Test Failed*** 1 failures.
