Expressive and extensible TDD/BDD assertion library for Python

Expects is an expressive and extensible TDD/BDD assertion library for Python.

Usage

Just import the expect callable and start writing test assertions.

from expects import expect

expect([]).to.be.empty

expect(False).not_to.be.true

expect({'name': 'Jack', 'email': '[e-mail]'}).to.have.key('name') \
                                                     .with_value.match('\w+')

expect(str).to.have.property('split')
