Add fixture so py.test can inject variables into function global
namespace.  Fixes failures in test_coordinate_vars
do not use foo < 0 if foo can be symbolic
Merge pull request #8119 from smichr/bound2

do not use < if arg might be symbolic
remove --slow option from py.test as it is not the appropriate way to use py.test
Rather than muck around with __globals__, define the appropriate local
variables in the test functions.
skip tests in test_pytest if running under pytest
Fix broken test test_math_lambda
use setup_module function to ensure pytest skips tests that have been
marked with 'disabled = True'
Removes mechanics printing deprecation warning. Fixes issue #7913.
Fix one-arg elliptic_e._eval_conjugate (ValueError was raised)
do not add tests that are not prereq

It is important not to add prerequisites to a result that are
not consistent with the assumption rules. This can lead to facts
being missed, something that will be intermittent in nature depending
on the order in which the assumptions are traversed to resolve the fact

for example:

>>> from sympy.core.assumptions import _assume_rules as R
>>> print filldedent(R.prereq['imaginary'])

set(['real', 'prime', 'irrational', 'antihermitian', 'nonpositive',
'composite', 'zero', 'integer', 'odd', 'even', 'commutative',
'positive', 'noninteger', 'negative', 'nonnegative', 'complex',
'rational'])

Having an answer to nonzero is not a prerequisite of knowing the
`imaginary` fact. The same is true for antihermitian.

>>> print filldedent(R.prereq['antihermitian'])

set(['imaginary'])
