This is my memo about writing autotest test case.
At least, it requires control file, python file and test code.
This is a test code directories.
[masami@moon]~/autotest-0.12.0/client/tests/pwrite_test% ls . src
.:
. .. control pwrite_test.py pwrite_test.py.bk pwrite_test.pyc src
src:
. .. Makefile pwrite_test.c
This is a control file. It defines some information e.g. test type, author and so forth.
- AUTHOR = "your name <your email="" address="">"
- EXPERIMENTAL = 'True'
-
- NAME = "pwrite_test"
- TEST_TYPE = "client"
- TEST_CLASS = "General"
- TEST_CATEGORY = "Functional"
- TIME = "SHORT"
- DOC =

- job.run_test('pwrite_test')
- </your>
AUTHOR = "your name "
EXPERIMENTAL = 'True' # Not really, but this is only for testing autotest...
# not testing _with_ autotest.
NAME = "pwrite_test"
TEST_TYPE = "client"
TEST_CLASS = "General"
TEST_CATEGORY = "Functional"
TIME = "SHORT"
DOC = """\
Test program for pwrite(2) and pread(2).
"""
job.run_test('pwrite_test')
job.run_test() calls your python script which implements test.test class.
This is a python code. this file name is pwrite_test.py.
In the setup(), it changes current directory from somewhere to "src" directory. src directory contains your my test code then call make command to create test program.

This is a test code.

Then, you can run your test code.
