Basic Nose Test
Below, code contains two simple unit tests verifying addition and subtraction operations, ensuring that 1 plus 1 equals 2 and 2 minus 1 equals 1, respectively.
Below, code sets up and tears down database connections for testing purposes using the Nose framework. The test_query()
function, decorated with @nose.with_setup()
, tests the database query functionality within this testing environment.
# test_math.py
def test_addition():
assert 1 + 1 == 2
def test_subtraction():
assert 2 - 1 == 1
To run these tests with Nose, simply execute
nosetests script_name.py
In the terminal within the directory containing the test file.
Output:
..
