failure of colcon test

[NIKO-SIMPLE]

I execute the instruction of readme.md, however, I had this promblem:

Summary: 14 packages finished [33.4s]
1 package had stderr output: libfranka
1 package had test failures: libfranka
what happened with libfranka?
I am going to use gazebo to simulate a robot and use moveit to control it. Unlikely, I don't know how to do that. I will appreciate if anyone could give me some help, if they are executable like readme.md, that's best!
