testvdrive 1.3.2

Python test by send / expect.

Python test drive utility

A nifty utility to test things.

The test case file drives a send / expect engine. The expect is then evaluated and the result is printed in a green colored 'OK' or a red colored 'ERR'.

./testvdrive.py testcase.txt

If you installed from pip, use:

testvdrive testcase.txt

The test case file contains the test instructions, one line per test. The format:

#   Context_string  Send_string     Expect_string   Find/Compare
#   --------------  -----------     -------------   ------------
#    for the user   what to test    what to expect  True if Find

Example test cases:

[ "Echo Command", "", "", True],                # NOOP
[ "Test ls", "ls", "Make", True],               # Do we have a Make file
[ "DF command", "df", "blocks", "regex" ],      # Search regex
[ "DF mregex", "df", ".*blo",  "mregex" ],      # Match regex

The output of example test cases (colored in terminal):

Echo Command     	 OK
Test ls          	 OK
DF command       	 OK
DF mregex        	 OK
