ShellSpec
A full-featured BDD unit testing framework for bash, ksh, zsh, dash, and all POSIX shells.
What is ShellSpec?
ShellSpec is a behavior-driven development (BDD) unit testing framework built for shell scripting. It allows developers to write structured, readable tests for bash, ksh, zsh, dash, and other POSIX shells, solving the problem of unreliable and untested shell scripts in cross-platform environments.
Shell script developers, DevOps engineers, and system administrators who write or maintain cross-platform shell scripts and need a robust testing framework to ensure reliability.
Developers choose ShellSpec for its comprehensive feature set—including mocking, coverage, and parallel execution—coupled with a clean DSL that integrates seamlessly with shell syntax, making it the most modern and full-featured testing tool for POSIX shells.
