Installation and Testing

Installing WebHelpers2

Install WebHelpers2 from PyPI:

$ pip install WebHelpers2

or check out the source:

$ git clone
$ pip install .

It depends on MarkupSafe and six, which pip will automatically install. Unidecode is optional; some of the text helpers will use it if it's installed.

To install all optional components and everything needed to run the tests and build the documentation in one step, check out the source and run:

$ pip install -r requirements.txt

WebHelpers2 has been tested on Python 2.7 and 3.4, and sometimes on 2.6. Earlier betas were tested on Python 3.3 and it's believed to still be compatible.

Python 3.2 Caveats

On Python 3.2 you must use MarkupSafe 0.15. Version 0.16 started using the "u" string prefix which is invalid in Python 3.0 - 3.2. (It was re-added in 3.3.)

WebHelpers2 is believed to run on Python 3.2 but this has not been tested. All "u" prefixes have been removed from the code but remain in some former doctests. (These are no longer supported as doctests but only as documentation.)

Running the unit tests

WebHelpers2 has an extensive test suite using PyTest. To run the tests:

$ pip install pytest
$ py.test

PyTest has lots of options. To run a specific test module, pass the filename; e.g., 'webhelpers2/tests/'.

PyTest sometimes has trouble finding tests on some systems. In that case, specify the test directory or filename as an argument.
