Hello all,

Running the scipy tests in sequence:

scipy.test() then, after the previous test finished without errors or failures I run: scipy.test('full') some tests fails (see below).

Exiting and starting a new python session and executing only the test suite:

scipy.test('full')

No failures or errors are reported. The test ends with: ... ---------------------------------------------------------------------- Ran 5832 tests in 423.039s OK (KNOWNFAIL=14, SKIP=42) <nose.result.TextTestResult run=5832 errors=0 failures=0>

What could be the problem?. Can we trust these tests results?

Python's default behavior is to raise warnings from the same place in the code only once. So when you re-run the tests it doesn't raise those warnings. The tests check that a warning is raised. Hence the failures.

Is there a way to run these failed tests individually so one can make sure the scipy system is working properly? perhaps an especific hard example could be usefull.

See http://readthedocs.org/docs/nose/en/latest/usage.html#selecting-tests
