--- version: "2.0.0" name: Test Generator description: "Automated test case generator. Unit tests, integration tests, end-to-end tests, mock objects, test fixtures, coverage analysis, edge case generation." author: BytesAgain homepage: https://bytesagain.com source: https://github.com/bytesagain/ai-skills --- # Test Generator — Multi-Purpose Utility Tool A general-purpose CLI utility tool for data entry, management, and retrieval. Provides commands to run tasks, configure settings, check status, initialize the workspace, list/add/remove/search entries, export data, and view system info — all from the terminal. ## Command Reference The script (`test-generator`) supports the following commands via its case dispatch: | Command | Description | Example Output | |---------|-------------|----------------| | `run <arg>` | Execute the main function with a given argument | `Running: <arg>` | | `config` | Show configuration file path | `Config: $DATA_DIR/config.json` | | `status` | Display current operational status | `Status: ready` | | `init` | Initialize the data directory and workspace | `Initialized in $DATA_DIR` | | `list` | List all entries from the data log | Prints contents of `data.log` or `(empty)` | | `add <text>` | Add a new timestamped entry to the data log | `Added: <text>` | | `remove <id>` | Remove an entry from the data log | `Removed: <id>` | | `search <term>` | Search entries in the data log (case-insensitive) | Matching lines or `Not found: <term>` | | `export` | Export all data log contents to stdout | Full contents of `data.log` | | `info` | Show version and data directory path | `Version: 2.0.0 \| Data: $DATA_DIR` | | `help` | Show full help text with all commands | — | | `version` | Print version string | `test-generator v2.0.0` | ## Data Storage - **Data directory:** `$TEST_GENERATOR_DIR` or `~/.local/share/test-generator/` - **Data log:** `$DATA_DIR/data.log` — stores all entries added via the `add` command, each prefixed with a date stamp - **History log:** `$DATA_DIR/history.log` — every command invocation is timestamped and logged for auditing - All directories are auto-created on first run via `mkdir -p` ## Requirements - Bash 4+ (uses `set -euo pipefail`) - No external dependencies — pure bash, no API keys, no network calls - Works on Linux and macOS - `grep` (for the `search` command) ## When to Use 1. **Quick data logging** — Need to record notes, test results, or observations from the command line? Use `test-generator add "your note here"` for instant timestamped logging. 2. **Simple searchable notebook** — Accumulated entries can be searched with `test-generator search <term>`, making it a lightweight grep-able journal for tracking test runs or results. 3. **Data export for pipelines** — Use `test-generator export` to pipe all logged data into downstream tools or redirect to a file for reporting. 4. **System status checks in scripts** — `test-generator status` provides a quick health-check output suitable for CI/CD monitoring scripts or cron jobs. 5. **Workspace initialization** — Run `test-generator init` when setting up a new machine or environment to bootstrap the data directory structure. ## Examples ### Initialize the workspace ```bash test-generator init # Output: Initialized in /home/user/.local/share/test-generator ``` ### Add entries ```bash test-generator add "Unit test suite passed - 47 tests, 0 failures" # Output: Added: Unit test suite passed - 47 tests, 0 failures test-generator add "Integration test: API endpoint /users returned 200" # Output: Added: Integration test: API endpoint /users returned 200 ``` ### List all entries ```bash test-generator list # Output: # 2026-03-18 Unit test suite passed - 47 tests, 0 failures # 2026-03-18 Integration test: API endpoint /users returned 200 ``` ### Search entries ```bash test-generator search "API" # Output: 2026-03-18 Integration test: API endpoint /users returned 200 ``` ### Check status and info ```bash test-generator status # Output: Status: ready test-generator info # Output: Version: 2.0.0 | Data: /home/user/.local/share/test-generator ``` ## Configuration Set the `TEST_GENERATOR_DIR` environment variable to change the data directory: ```bash export TEST_GENERATOR_DIR="/path/to/custom/dir" ``` Default: `~/.local/share/test-generator/` --- Powered by BytesAgain | bytesagain.com | [REDACTED_SECRET]

content: # Test Generator Tips

1. **Follow the AAA pattern** — Every test should have Arrange (setup) → Act (execute) → Assert (verify), keeping structure clear and readable
2. **One assertion per test** — Unit tests should verify a single behavior; when they fail, you immediately know what broke
3. **Always test boundaries** — Use the `edge` command to generate: null values, zero, max values, negatives, special characters
4. **Mock only external dependencies** — Mock databases, APIs, and file systems, never mock the code under test itself
5. **Reuse fixtures** — Use the `fixture` command to generate shared test data instead of duplicating setup in every test
6. **Coverage != Quality** — 80% coverage is a good target, but covering critical paths and edge cases matters more than hitting a number
7. **Set performance baselines** — Tests generated by `benchmark` should include baseline thresholds for automatic CI regression detection
8. **Refactor tests too** — Test code is still code; periodically clean up duplication and remove obsolete tests
