Python Unit Test Automation

Listing 4-10.  test_module10.py
from nose.tools import timed
import time
@timed(.1)
def test_case01():
    time.sleep(.2)
This test fails, as it takes more time to finish the execution of the test than is allotted 
in the @timed() decorator. The output of execution is as follows:
In setUpPackage()...
test.test_module08.test_case01 ... FAIL
In tearDownPackage()...

Report Generation
Let’s look at the various ways to generate comprehensible reports using nose.
Creating an XML Report
nose has a built-in feature for generating XML reports. These are xUnit-style formatted 
reports. You have to use --with-xunit for generating the report. The report is generated 
in the current working directory.
Run the following command in the test directory:
nosetests test_module01.py -vs --with-xunit
The output will be as follows:
In setUpPackage()...
test.test_module01.test_case01 ... ok
In tearDownPackage()...
