About:
testscript is a command-line tool that executes integration tests defined in simple .txtar archive files. It creates temporary filesystems from these archives, runs specified commands against them, and verifies the expected output. This provides a lightweight, self-contained method for testing complex command-line workflows and reproducible environments.
Key Features:
  • Declarative test definitions using .txtar format
  • Automatic setup and teardown of isolated test environments
  • Built-in commands for filesystem manipulation and execution
  • Reproducible and portable test execution
Use Cases:
  • Testing CLI application behavior in controlled filesystem states
  • Verifying installation scripts and package managers
  • Automating complex shell script workflows
Alternatives:
  • bats – Bats uses shell scripts for assertions, while testscript uses declarative archive files for environment setup.
  • shunit2 – shunit2 is a xUnit-style framework for shell, whereas testscript focuses on end-to-end integration testing via filesystem snapshots.
