'''External test used to represent user formatted results in the report.
This test has been designed in order to offer the possibility to define and run
user-defined tests outside valjean and include their results in a report, along
with the native valjean tests.
The user is responsible for defining and representing the test results. The
representation must be done with templates (see :mod:`.templates` module).
For example, the simplest case is a custom plot to represent a test. In that
case, if the path to the image is known a :class:`~.templates.TextTemplate` can
be created and given to the test:
>>> txtemp = TextTemplate("And this represents Javert\\n\\n"
... ".. image:: ../../doc/src/images/javert.jpg\\n\\n")
>>> textr = TestExternal(txtemp, name='', success=True).evaluate()
>>> print(bool(textr))
True
