About:
Cram is a lightweight, functional testing framework designed for command-line applications. It validates command output and exit codes using a simple diff-based format, making it ideal for testing shell scripts and CLI tools. Its straightforward syntax and integration capabilities streamline the process of ensuring command-line tools behave as expected.

Key Features:

Simple, human-readable test format
Validates stdout, stderr, and exit codes
Integrates with Python and other build systems
Cross-platform compatibility

Use Cases:

Testing shell scripts and automation tools
Verifying command-line application behavior
Documentation testing (doctests for CLI)

Alternatives:

bats – Bash-based testing framework, more verbose but native to Bash
pytest – General Python testing framework, requires more boilerplate for CLI testing
