test: Add automated tests for clear history functionality - #289
Conversation

Pull request overview
This PR claims to add automated tests for clear history functionality, but actually only implements tests for history screen navigation and transaction display. The tests do not test any clear history functionality - they verify navigation to/from the history screen, displaying transactions, and handling empty transaction lists. The actual clear history feature exists in the editSystemSettingsScreen, not the historyScreen being tested here.
Key Changes:
- Added 5 new test functions for history screen functionality
- Tests cover history screen navigation, back button, and transaction display
- Missing: actual clear history functionality tests

This test is named test_clear_history_button_exists but does not actually test whether a clear history button exists or verify any clear history functionality. The test only navigates to the history screen and verifies the screen loaded. Consider either renaming this test to match what it actually tests (e.g., test_history_screen_loads_with_transactions) or implementing the actual clear history functionality test. Note that clear history functionality exists in the editSystemSettingsScreen, not the historyScreen.

Import statements should be placed at the top of the file, not inside function bodies. Move the datetime import to the top of the file with other imports for better code organization and to follow Python best practices.

Import statements should be placed at the top of the file, not inside function bodies. This is a duplicate import of datetime that should be moved to the module level with other imports.

The PR title and description claim to add tests for "clear history functionality", but none of the tests in this file actually test clearing history. The tests only verify history screen navigation and display of transactions. The clear history feature exists in the editSystemSettingsScreen and would need to be tested there. Either update the tests to actually test clear history functionality, or update the PR title/description to accurately reflect that these tests cover history screen navigation and display.

There is repeated code across multiple test functions for user setup (getting user, adding credits, setting current patron). Consider extracting this common setup logic into a helper function or fixture to reduce code duplication and improve maintainability.
