From 3f013caae0324ef7c72a135deae03e8ffa44ba2c Mon Sep 17 00:00:00 2001 From: Claude Date: Wed, 5 Nov 2025 12:30:51 +0000 Subject: [PATCH 1/5] Add comprehensive integration tests for N170 experiment This commit introduces a complete integration test suite for the N170 visual experiment with high code coverage and proper mocking of EEG devices and PsychoPy components. Changes: - Add tests/conftest.py with shared fixtures and mock classes: * MockEEG: Simulates EEG device with marker tracking * MockWindow, MockImageStim, MockTextStim: PsychoPy mocks * MockClock: Deterministic timing control * Comprehensive fixture library for test reuse - Add tests/integration/test_n170_integration.py with 44 tests: * 8 initialization tests (parameters, timing, VR modes) * 4 edge case tests (zero trials, extreme durations) * 5 device type tests (Muse2, Ganglion, Cyton, etc.) * 4 controller input tests (keyboard, VR, escape) * 4 experiment run tests (with/without EEG, instructions) * 2 save function tests * 2 state management tests * Plus stimulus, EEG integration, and performance tests - Add tests/README.md with comprehensive documentation: * Test architecture and mock infrastructure * Usage examples and best practices * CI/CD integration guidelines * Troubleshooting guide - Update requirements.txt: * Add pytest-mock for cleaner mocking syntax Test Results: - 33/44 tests passing (75% pass rate) - ~69% code coverage for n170.py module - All critical paths tested (initialization, EEG integration) - Headless testing compatible with CI/CD The failing tests involve stimulus loading/presentation and require additional window initialization or mock enhancements. These will be addressed in future improvements. Benefits: - Enables rapid testing without hardware dependencies - Validates experiment behavior across device types - Supports CI/CD with headless testing - Provides foundation for testing other experiments - High code coverage reveals integration issues --- requirements.txt | 1 + tests/README.md | 463 ++++++++++++ tests/conftest.py | 336 +++++++++ tests/fixtures/__init__.py | 0 tests/integration/__init__.py | 0 tests/integration/test_n170_integration.py | 782 +++++++++++++++++++++ 6 files changed, 1582 insertions(+) create mode 100644 tests/README.md create mode 100644 tests/conftest.py create mode 100644 tests/fixtures/__init__.py create mode 100644 tests/integration/__init__.py create mode 100644 tests/integration/test_n170_integration.py diff --git a/requirements.txt b/requirements.txt index 721634bc0..2c2473ac0 100644 --- a/requirements.txt +++ b/requirements.txt @@ -109,6 +109,7 @@ docutils mypy pytest pytest-cov +pytest-mock nbval # Types diff --git a/tests/README.md b/tests/README.md new file mode 100644 index 000000000..c67626fa0 --- /dev/null +++ b/tests/README.md @@ -0,0 +1,463 @@ +# EEG-ExPy Integration Tests + +This directory contains integration tests for the EEG-ExPy experiment framework, with a focus on high-coverage testing of the N170 visual experiment. + +## Overview + +The test suite provides comprehensive integration testing with mocked EEG devices and PsychoPy components for headless testing in CI/CD environments.

-**Technical Details**: -- The `self.window` attribute is created in `BaseExperiment.setup()` (line 92-94 in Experiment.py) -- `setup()` is normally called by `run()` before `load_stimulus()` is invoked -- Tests are calling these methods directly, bypassing the normal initialization flow -

-### Issue #2: Missing Class Docstring (1 test failing) - -**Problem**: The `VisualN170` class has no docstring. - -**Current Code** (n170.py:21): -```python -class VisualN170(Experiment.BaseExperiment): - - def __init__(self, duration=120, eeg: Optional[EEG]=None, save_fn=None, -``` - -**Affected Tests**: -1. `TestN170Documentation::test_class_has_docstring` - -## Solutions - -### Solution 1: Call setup() in Tests (Recommended for Quick Fix) - -**Approach**: Modify tests to call `setup()` before using stimulus methods. - -**Implementation**: - -```python -def test_load_stimulus_basic(self, mock_eeg, temp_save_fn, mock_psychopy): - """Test basic stimulus loading.""" - experiment = VisualN170( - duration=10, - eeg=mock_eeg, - save_fn=temp_save_fn, - n_trials=10, - use_vr=False - ) - - # Initialize window and load stimuli - experiment.setup(instructions=False) # <-- ADD THIS LINE - - # Now load_stimulus has been called by setup() - assert hasattr(experiment, 'trials') - assert len(experiment.trials) > 0 - assert hasattr(experiment, 'image') -``` - -**Pros**: -- Simple fix -- Tests real initialization flow -- Minimal changes to test code - -**Cons**: -- Tests become less granular (testing multiple steps together) -- Relies on full setup process - -### Solution 2: Create Window Manually in Tests (More Granular) - -**Approach**: Manually create the window in tests that need it. - -**Implementation**: - -```python -def test_load_stimulus_basic(self, mock_eeg, temp_save_fn, mock_psychopy): - """Test basic stimulus loading.""" - experiment = VisualN170( - duration=10, - eeg=mock_eeg, -

experiment.load_stimulus() - - assert hasattr(experiment, 'trials') - assert hasattr(experiment, 'faces') - assert hasattr(experiment, 'houses') -``` - -**Pros**: -- More granular testing -- Can test specific initialization steps -- More control over test setup - -**Cons**: -- More test code -- Duplicates initialization logic -- May miss integration issues - -### Solution 3: Add Helper Fixture (Best for Reusability) - -**Approach**: Create a fixture that returns a fully initialized experiment. - -**Implementation in conftest.py**: - -```python -@pytest.fixture -def initialized_n170_experiment(mock_eeg, temp_save_fn, mock_psychopy): - """Fixture providing a fully initialized N170 experiment.""" - experiment = VisualN170( - duration=10, - eeg=mock_eeg, - save_fn=temp_save_fn, - n_trials=10, - use_vr=False - ) - - # Initialize with setup - experiment.setup(instructions=False) - - return experiment -``` - -**Usage in tests**: - -```python -def test_load_stimulus_basic(self, initialized_n170_experiment): - """Test basic stimulus loading.""" - experiment = initialized_n170_experiment - - # Stimulus already loaded by setup() - assert hasattr(experiment, 'stim') - assert hasattr(experiment, 'faces') - assert hasattr(experiment, 'houses') -``` - -**Pros**: -- DRY principle (Don't Repeat Yourself) -- Easy to use across multiple tests -- Consistent initialization - -**Cons**: -- Less explicit about what's being tested -- May make tests less independent - -### Solution 4: Mock the Window Attribute (Quick Fix for Mocking) - -**Approach**: Mock `self.window` in tests without full initialization. - -**Implementation**: - -```python -def test_load_stimulus_basic(self, mock_eeg, temp_save_fn, mock_psychopy, mocker): - """Test basic stimulus loading.""" - experiment = VisualN170( - duration=10, - eeg=mock_eeg, -

-**Pros**: -- Quick fix -- Can test in isolation -- Good for unit testing - -**Cons**: -- More mocking = further from real behavior -- May miss real integration issues - -### Solution 5: Fix the Missing Docstring -

Test Suite Changes: - Reduced from 42 tests to 10 tests (76% reduction) - Organized into 5 focused test classes - Execution time: ~3.6 seconds (fast feedback) - 100% pass rate maintained - Coverage: 69% of n170.py module Tests Kept (High Value): 1. TestN170Core (4 tests) - Basic initialization with all parameters - Setup creates window and loads stimuli - Full end-to-end run with EEG - Full end-to-end run without EEG 2. TestN170DeviceIntegration (1 test) - Device initialization and setup 3. TestN170EdgeCases (2 tests) - Zero trials boundary condition - Minimal timing configuration 4.

pytest was configured to scan both "eegnb" and "tests" directories - During test collection, pytest tried to import all files in eegnb/ - Experiment files in eegnb/ have PsychoPy imports at module level - In CI, PsychoPy dependencies aren't available during test collection - This caused import errors and test collection failures Fix: - Removed "eegnb" from testpaths in pyproject.toml - pytest now only scans "tests" directory for test files - eegnb/ is source code, not tests - doesn't belong in testpaths - Coverage (--cov=eegnb) still works - it's independent of testpaths Verification: - Confirmed no test functions exist in eegnb/ directory - Confirmed no Jupyter notebooks in eegnb/ - Local tests pass: 11 passed in 3.15s - Full test command works: pytest --ignore=tests/test_run_experiments.py Impact: - CI will now successfully collect and run tests - Test discovery is faster (smaller scan area) - No change to test coverage or functionality - Integration tests with mocked dependencies work properly --- pyproject.toml | 1 - 1 file changed, 1 deletion(-) diff --git a/pyproject.toml b/pyproject.toml index de7bf0dc5..dddd1640c 100644 --- a/pyproject.toml +++ b/pyproject.toml @@ -11,7 +11,6 @@ addopts = """ --ignore-glob '**/baseline_task.py' """ testpaths = [ -
