I am learning to use unittest.
I have written a program that runs as it should.
247 tests give me a satisfactory answer.
I have now added one more test and I get an error which I do not understand.
The two relevant tests are:
def test_type_capitalsadvanced(self):
self.assertEqual(type(self.capitalsadvanced), numpy.ndarray)
def test_zero_in_capitalsadvanced(self):
self.assertIn(self.capitalsadvanced, 0.0)
The error message is:
Traceback (most recent call last):
File
"/Users/sydney/Capital/Capital_with_productivity/Current_Versions/testPOCWP_V2.py",
line 320, in test_zero_in_capitalsadvanced
self.assertIn(self.capitalsadvanced, 0.0)
File "/Users/sydney/anaconda/lib/python3.6/unittest/case.py", line
1077, in assertIn
if member not in container:
TypeError: argument of type 'float' is not iterable
Final output from the tests is :
Ran 247 tests in 1.179s
FAILED (failures=9, errors=1)
The failures all arise from a 'nan'.
It is this problem that I am trying to resolve.
My problem is that the first test tells me correctly that the object
capitalsadvanced is a numpy.ndarray. But the second test error message
says it is a float.
I should add that the program creates the initial data set by making use
of the random function which is given a mean to work with. Thus each
test run will be with different input data. But repeated tests show the
same errors.
When I run the same tests with predetermined, fixed data I get no errors
and no 'nan' errors.
Any guidance will be very welcome.
