Automated tests¶
The tests package provides automated testing for
`pymenu`.
Tests are known to assess software behavior and find bugs. They are also used as part of the code’s documentation, as a design tool or for preventing regressions.

Unit tests¶
Exercise the smallest pieces of testable software in the application to determine whether they behave as expected.
Unit tests should not
- call out into (non-trivial) collaborators,
- access the network,
- hit a database,
- use the file system or
- spin up a thread.
Most of the unit tests can be found directory in the code documentation
and are run using doctest. When they cannot be simple or extensible
enough with impeding readability, they should be written in the
tests.unit package.
Integration tests¶
Verify the communication paths and interactions between components to detect interface defects.
The line between unit and integration tests may become blurry. When in doubt,
you are most certainly thinking integration tests. Write those in the
tests.integration package.
Functional tests¶
Functional tests check a particular feature for correctness by comparing
the results for a given input against the specification. They are often used
as an executable definition of a user story. Write those in the
tests.functional package.
Regression tests¶
A test that was written when a bug was found (and then fixed). It ensures
that this specific bug will not occur again. The full name is non-regression
test. It can also be a test made prior to changing an application to make
sure the application provides the same outcome. Put these in the
tests.regression package.
