# Database Manager Unit Tests
|
|
|
|
Unit tests for `DatabaseManager` are implemented in `src/g2_2025_imu_reader_pkg/test/DatabaseManager.test.cpp` using Google Test and ROS2 test utilities. The tests are designed to work reliably whether a database connection is available or not, focusing on error handling and method behavior validation.
|
|
|
|
## Test Cases
|
|
|
|
### 1. ConstructorTest
|
|
|
|
**Description:** Verifies that DatabaseManager can be created without crashing and proper initialization occurs.
|
|
|
|
- **Test Action:** Create DatabaseManager instance with ROS2 logger
|
|
- **Expected Result:** Instance created successfully without exceptions
|
|
|
|
### 2. ConnectionStatusTest
|
|
|
|
**Description:** Tests that the `is_connected()` method returns a valid boolean value.
|
|
|
|
- **Test Action:** Call `is_connected()` method
|
|
- **Expected Result:** Returns either `true` or `false` (no crashes or invalid states)
|
|
|
|
### 3. QueuePendingCombinationsTest
|
|
|
|
**Description:** Verifies retrieval of pending student-course combinations that need exam results.
|
|
|
|
- Test action: Call `store_imu_data(linear_x, linear_y, linear_z, ang_x, ang_y, ang_z)` without an active DB connection.
|
|
- Expected result: Returns `false` and does not throw — method must check connection status before DB operations.
|
|
|
|
### 4. CreateTablesNoCrash
|
|
|
|
Description: Verifies calling `create_tables()` without an active connection is safe.
|
|
|
|
- Test action: Call `create_tables()` on a manager that is not connected.
|
|
- Expected result: No exception thrown; the function should be a no-op when no DB connection exists.
