I get the following output:

FAIL: testRootLocus (rlocus_test.TestRootLocus)

Basic root locus plot

Traceback (most recent call last):

AssertionError:
Arrays are not almost equal to 6 decimals

(mismatch 100.0%)
x: array([-1.5-1.6583124j, -1.5+1.6583124j])
y: array([-1.5+1.6583124j, -1.5-1.6583124j])

I guess that test shouldn't fail just because of a different element order in the array?
