TEST_F() [1/11]

TEST_F	(	TrajectoryGeneratorLINTest	,
		cartesianSpaceGoal
	)

test the lin planner with Cartesian goal

Definition at line 264 of file unittest_trajectory_generator_lin.cpp.

TEST_F() [2/11]

TEST_F	(	TrajectoryGeneratorLINTest	,
		cartesianTrapezoidProfile
	)

test the trapezoid shape of the planning trajectory in Cartesian space

The test checks translational path for a trapezoid velocity profile. Due to the way the acceleration is calculated 1 or 2 intermediate points occur that are neither acceleration, constant or deceleration.
