Function Documentation

◆ TEST_F() [1/5]

TEST_F	(	CanBusManagerTest	,
		DestructorCallsStopReading	)

Verifies that stopReading() is triggered in the destructor.

Test: Ensures that stopReading() is called when CanBusManager is destroyed.

This test initializes CanBusManager, then deletes it and confirms that stopReading() was called exactly once.

Note: This test indirectly verifies proper cleanup behavior in the destructor.

Definition at line 152 of file test_CanBusManager.cpp.

◆ TEST_F() [2/5]

TEST_F	(	CanBusManagerTest	,
		InitializeFailsWhenControllerFails	)

Ensures that initialize() fails when the controller fails to initialize.

Test: Tests CanBusManager::initialize() when init() fails.

This test sets up a mock expectation that init() will return false, verifying that initialize() correctly fails in this case.

Definition at line 115 of file test_CanBusManager.cpp.

◆ TEST_F() [3/5]

TEST_F	(	CanBusManagerTest	,
		InitializeSucceedsWhenControllerSucceeds	)

Ensures that initialize() succeeds when the controller initializes successfully.

Test: Tests CanBusManager::initialize() when init() succeeds.

This test sets up a mock expectation that init() will return true, verifying that initialize() correctly returns true.

◆ TEST_F() [4/5]

TEST_F	(	CanBusManagerTest	,
		RpmSignalEmitsCorrectly	)

Ensures that the RPM signal emits the correct value.

Test: Tests if the rpmUpdated signal is emitted correctly.

Similar to SpeedSignalEmitsCorrectly, this test verifies that rpmUpdated emits the expected RPM value.

◆ TEST_F() [5/5]

TEST_F	(	CanBusManagerTest	,
		SpeedSignalEmitsCorrectly	)

Ensures that the speed signal is emitted with the correct value.

Test: Tests if the speedUpdated signal is emitted correctly.

This test uses QSignalSpy to verify that speedUpdated emits the expected speed value when the mock controller triggers the signal.
