Scruf

Scruf is a functional testing framework for command line applications. It is heavily inspired by cram. This is currently early in development and while I aim to maintain the current interface breaking changes may occur.

usage: scruf [-h] [--no-cleanup] [-s SHELL] [-i INDENT] [-e ENV_FILE]
             FILE [FILE ...]

positional arguments:
  FILE                  File(s) to be tested

optional arguments:
  -h, --help            show this help message and exit
  --no-cleanup          Avoid cleaning up temporary test directory
  -s SHELL, --shell SHELL
                        Path to shell to be used to run tests with. Default is
                        '/bin/sh'
  -i INDENT, --indent INDENT
                        String to be used for detecting indentation when
                        parsing tests. Default is 4 spaces, use a literal '\t'
                        to denote a tab character
  -e ENV_FILE, --env-file ENV_FILE
                        Name of config file to read environment variables from
  --version             show program's version number and exit
  --strict              Whether tests should be run in strict mode. In this
                        mode a test that does not check each line of output is
                        considered to have failed

Example test:

# in my_test.scf
# the following line is a test description
Verify 'cat' reads file contents
# Run some commands to setup environment
[SETUP]$ echo 'some text' > test.txt
[SETUP]$ echo '1234' >> test.txt
# The command to test (note indentation)
    $ cat test.txt
    some text
    [RE] ^\d+$

Running:

scruf my_test.scf
# Testing: my_test.scf
1..1
ok 1 - Verify 'cat' reads file contents
