TEST_F() [1/13]

TEST_F	(	LongitudinalSpeedPlannerTest	,
		getAccelerationDuration_acceleration
	)

Note

Test calculations correctness of acceleration duration with some positive acceleration and speed substantially below target_speed.

Actual duration calculated by hand based on input. Tolerance value chosen as very small, but acceptable numerical error.

TEST_F() [2/13]

TEST_F	(	LongitudinalSpeedPlannerTest	,
		getDynamicStates_maxJerk
	)

Note

Test functionality aggregation used in other classes. Test calculations correctness with target_speed = max speed and current speed = 0

• goal is to test the situation when acceleration is so long that max jerk is reached.

TEST_F() [3/13]

TEST_F	(	LongitudinalSpeedPlannerTest	,
		getDynamicStates_shortAccel
	)

Note

Test functionality aggregation used in other classes. Test calculations correctness with target_speed slightly smaller than current speed

• goal is to test the situation when the max jerk is not reached because the target_speed is reached first.

TEST_F() [4/13]

TEST_F	(	LongitudinalSpeedPlannerTest	,
		getDynamicStates_targetSpeedOverLimit
	)

Note

Test functionality aggregation used in other classes. Test function behavior when target_speed is bigger than max speed.

TEST_F() [5/13]

TEST_F	(	LongitudinalSpeedPlannerTest	,
		getRunningDistance_longTime
	)

Note

Test functionality aggregation used in other classes. Test calculations correctness with target_speed = 0 and current speed = 50 (or other cruising speed)

• goal is to test the situation when the target speed is reached takes longer to reach so the loop has to run multiple times.

TEST_F() [6/13]

TEST_F	(	LongitudinalSpeedPlannerTest	,
		getRunningDistance_shortTime
	)

Note

Test functionality aggregation used in other classes. Test calculations correctness with target_speed slightly bigger than current speed

• goal is to test the situation when the target speed is reached in little time, so the loop executes only several times.

TEST_F() [7/13]

TEST_F	(	LongitudinalSpeedPlannerTest	,
		getRunningDistance_zero
	)

Note

Test functionality aggregation used in other classes. Test calculations correctness with target_speed identical to current speed so that the time is 0.

TEST_F() [8/13]

TEST_F	(	LongitudinalSpeedPlannerTest	,
		isAccelerating_false
	)

Note

Test basic functionality. Test with non accelerating situation.

TEST_F() [9/13]

TEST_F	(	LongitudinalSpeedPlannerTest	,
		isAccelerating_true
	)

Note

Test basic functionality. Test with an accelerating situation.

TEST_F() [10/13]

TEST_F	(	LongitudinalSpeedPlannerTest	,
		isDecelerating_false
	)

Note

Test basic functionality. Test with non decelerating situation.

TEST_F() [11/13]

TEST_F	(	LongitudinalSpeedPlannerTest	,
		isDecelerating_true
	)

Note

Test basic functionality. Test with a decelerating situation.

TEST_F() [12/13]

TEST_F	(	LongitudinalSpeedPlannerTest	,
		isTargetSpeedReached_different
	)

Note

Test functionality used in other classes. Test calculations correctness with target_speed differing from current speed by several units.

TEST_F() [13/13]

TEST_F	(	LongitudinalSpeedPlannerTest	,
		isTargetSpeedReached_same
	)

Note

Test functionality used in other classes. Test calculations correctness with target_speed differing from current speed by very small amount

• goal is to simulate equal speed but with numerical noise.
