shell-test-mock-path-pattern

What problem does it solve?

This Skill addresses the challenge of testing shell scripts that rely on external commands without the need for those commands to be installed or configured, streamlining the testing process.

Core Features & Use Cases

• Mocking External Commands: Simulate external command behavior without actual command installation.
• Path Override and Logging: Override the PATH environment variable to use mock executables and log command invocations for verification.
• Use Case: Ideal for testing shell scripts that interact with tools like crewchief, gh, or jq, allowing for accurate argument passing and command orchestration verification without real command execution.

Quick Start

Run the following command to test your shell script:

setup() {
    TEST_TMP=$(mktemp -d)
    mkdir -p "$TEST_TMP/mock-bin"
    touch "$TEST_TMP/mock.log"
}
