Test objects which pass equality checks with other objects
Usage
from h_matchers import Any
import re
assert [1, 2, ValueError(), print, print] == [
Any(),
Any.int(),
Any.instance_of(ValueError),
Any.function(),
Any.callable()
]
assert ["easy", "string", "matching"] == [
Any.string(),
Any.string.containing("in"),
Any.string.matching('^.*CHING!', re.IGNORECASE)
]
assert "http://www.example.com?a=3&b=2" == Any.url(
host='www.example.com', query=Any.mapping.containing({'a': 3}))
assert 5 == Any.of([5, None])
assert "foo bar" == All.of([
Any.string.containing('foo'),
Any.string.containing('bar')
])
assert user == Any.object.of_type(MyUser).with_attrs({"name": "Username"})
assert "http://example.com/path" == Any.url.with_host("example.com")
assert prepared_request == (
Any.request
.with_url(Any.url.with_host("example.com"))
.containing_headers({'Content-Type': 'application/json'})
)

Hacking
Installing h-matchers in a development environment
You will need
-
pyenv Follow the instructions in the pyenv README to install it. The Homebrew method works best on macOS. On Ubuntu follow the Basic GitHub Checkout method.
Clone the git repo
git clone https://github.com/hypothesis/h-matchers.git
This will download the code into a h-matchers
directory
in your current working directory. You need to be in the
h-matchers
directory for the rest of the installation
process:
cd h-matchers
Run the tests
make test
That's it! You’ve finished setting up your h-matchers
development environment. Run make help
to see all the commands that're
available for linting, code formatting, packaging, etc.
Updating the Cookiecutter scaffolding
This project was created from the https://github.com/hypothesis/h-cookiecutter-pypackage/ template. If h-cookiecutter-pypackage itself has changed since this project was created, and you want to update this project with the latest changes, you can "replay" the cookiecutter over this project. Run:
make template
This will change the files in your working tree, applying the latest updates from the h-cookiecutter-pypackage template. Inspect and test the changes, do any fixups that are needed, and then commit them to git and send a pull request.
If you want make template
to skip certain files, never changing them, add
these files to "options.disable_replay"
in
.cookiecutter.json
and commit that to git.
If you want make template
to update a file that's listed in disable_replay
simply delete that file and then run make template
, it'll recreate the file
for you.
