A test framework for Python that makes mocking and iterating over code with tests a breeze

Project description

TestSlide

Build Status Coverage Status Documentation Status GitHub license PyPI version Code style: black

A test framework for Python that enable unit testing / TDD / BDD to be productive and enjoyable.

Its well behaved mocks with thorough API validations catches bugs both when code is first written or long in the future when it is changed.

The flexibility of using them with existing unittest.TestCase or TestSlide's own test runner let users get its benefits without requiring refactoring existing code.

Quickstart

Install:

pip install TestSlide

Scaffold the code you want to test backup.py:

class Backup:
  def delete(self, path):
    pass

Write a test case backup_test.py describing the expected behavior:

import testslide, backup, storage

class TestBackupDelete(testslide.TestCase):
  def setUp(self):
    super().setUp()
    self.storage_mock = testslide.StrictMock(storage.Client)
    # Makes storage.Client(timeout=60) return self.storage_mock
    self.mock_constructor(storage, 'Client')\
      .for_call(timeout=60)\
      .to_return_value(self.storage_mock)

  def test_delete_from_storage(self):
    # Set behavior and assertion for the call at the mock
    self.mock_callable(self.storage_mock, 'delete')\
      .for_call('/file/to/delete')\
      .to_return_value(True)\
      .and_assert_called_once()
    backup.Backup().delete('/file/to/delete')

TestSlide's StrictMock, mock_constructor() and mock_callable() are seamlessly integrated with Python's TestCase.

Run the test and see the failure:

Failing test

TestSlide's mocks failure messages guide you towards the solution, that you can now implement:

import storage

class Backup:
  def __init__(self):
    self.storage = storage.Client(timeout=60)

  def delete(self, path):
    self.storage.delete(path)

And watch the test go green:

Passing test

It is all about letting the failure messages guide you towards the solution. There's a plethora of validation inside TestSlide's mocks, so you can trust they will help you iterate quickly when writing code and also cover you when breaking changes are introduced.
