shellspec

What problem does it solve?

ShellSpec provides a complete unit testing framework for Bash and POSIX shells, enabling repeatable, readable tests. It helps teams write, run, and maintain tests, mock dependencies, and integrate testing into CI workflows for shell-based projects.

Core Features & Use Cases

• Comprehensive unit testing framework for Bash and POSIX shells using ShellSpec with a DSL (Describe/Context/It, When/The).
• Supports mocking, output capture, test isolation, and cross-shell compatibility.
• Use cases include validating script logic, debugging failures, refactoring for testability, and setting up test infrastructure.

Quick Start

Install ShellSpec, initialize your project, and write your first spec using Describe and It blocks. Create spec files under spec/ and run tests with shellspec. For debugging, use --xtrace; for coverage, enable kcov with --kcov.
