A collection of helpers and mock objects for unit tests and doc tests.
Project description
TestFixtures is a collection of helpers and mock objects that are useful when writing unit tests or doc tests.
If you’re wondering why “yet another mock object library”, testing is often described as an art form and as such some styles of library will suite some people while others will suite other styles. This library contains common test fixtures the author found himself repeating from package to packages and so decided to extract them into their own library and give them some tests of their own!
The areas of testing this package can help with are listed below:
Comparing objects and sequences
Better feedback when the results aren’t as you expected along with support for comparison of objects that don’t normally support comparison.
Mocking out objects and methods
Easy to use ways of stubbing out objects, classes or individual methods for both doc tests and unit tests. Special helpers are provided for testing with dates and times.
Testing logging
Helpers for capturing logging output in both doc tests and unit tests.
Testing stream output
Helpers for capturing stream output, such as that from print statements, and making assertion about it.
Testing with files and directories
Support for creating and checking files and directories in sandboxes for both doc tests and unit tests.
Testing exceptions
Easy to use ways of checking that a certain exception is raised, even down the to the parameters the exception is raised with.
