Python/Unit Tests/CheatSheet

I inevitably look up the same syntax again and again while writing unit tests.

Snippets:

# Parent classes
unittest.TestCase
unittest.IsolatedAsyncioTestCase

# Assertions
assertEqual(), assertNotEqual() # assertEquals is deprecated
assertTrue(), assertFalse()
assertAlmostEqual(), assertNotAlmostEqual()
assertRaises(), assertRaisesRegex()
assertRegex(), assertNotRegex()

# Mocks
from unittest.mock import (
  mock, Mock, AsyncMock, MagicMack,
  patch, create_autospec
)

## Auto specs: create_autospec

call objects are weird tuples that have special rules for equality
- Implemented as _Call
- .args, .kwargs are the key properties
