Overview

​

High-level description

This file contains unit tests for the utility functions defined in cassiopeia/mixins/utilities.py. It tests the functionality of various utility functions related to handling ambiguous states in character matrices and finding duplicate groups.

TestMixinUtilities

​

Description

This is a test class that inherits from unittest.TestCase. It contains several test methods to verify the functionality of utility functions from the cassiopeia.mixins.utilities module.

​

Internal Logic

The class defines three test methods:

1. test_is_ambiguous_state: Tests the is_ambiguous_state function.
2. test_unravel_states: Tests the unravel_ambiguous_states function.
3. test_find_duplicated_character_states: Tests the find_duplicate_groups function.

​

test_is_ambiguous_state

​

Description

This method tests the is_ambiguous_state function from the utilities module.

​

Internal Logic

• Asserts that (1, 2) is recognized as an ambiguous state.
• Asserts that 1 is not recognized as an ambiguous state.

​

test_unravel_states

​

Description

This method tests the unravel_ambiguous_states function from the utilities module.

​

Internal Logic

• Tests the function with an array containing both ambiguous and non-ambiguous states.
• Tests the function with an array containing only non-ambiguous states.
• Asserts that the output matches the expected unraveled list in both cases.

​

test_find_duplicated_character_states

​

Description

This method tests the find_duplicate_groups function from the utilities module.

​

Internal Logic

• Creates a sample character matrix using pandas DataFrame.
• Calls the find_duplicate_groups function on the character matrix.
• Checks if the returned duplicate mappings contain the expected entries.
• Verifies that the keys and values in the duplicate mappings match the expected groups.

​

Dependencies

​

Error Handling

The test methods use assertions to verify the correctness of the utility functions. If any assertion fails, an AssertionError will be raised, indicating a test failure.

​

Notes

• The test file uses the unittest framework, which is a standard Python testing library.
• The tests cover various scenarios, including ambiguous states and duplicate character states in matrices.
• The test_find_duplicated_character_states method uses a complex character matrix with ambiguous states to thoroughly test the find_duplicate_groups function.
