🧩 Installation

pip install jps-test-artifact-python-utils

or install in editable mode for local development:

git clone [e-mail]:jai-python3/jps-test-artifact-python-utils.git  
cd jps-test-artifact-python-utils  
pip install -e .

🧩 setup-test-artifacts

Sets up a new test artifact instance directory by copying representative input, output, and script files into a new workspace.

Usage

setup-test-artifacts --indir <test-case-dir> [--script-dir <scripts-dir>]

Example

setup-test-artifacts --indir synthentic-genomics-pipeline/v1.2.0/comp_analysis/test-case-001/

This generates a fully configured test workspace with expected structure and a runnable shell script.

---

🧩 create-md5-manifest

Generates an md5_manifest.txt file listing all files under a given directory with their MD5 checksums, sizes, and timestamps.

Usage

create-md5-manifest --test-case-dir <path> --manifest-file <path>

Example Output

## method-created: /scripts/create_md5_manifest.py
## date-created: 2025-10-28 13:22:01
## created-by: jsundaram
## Columns:
## 1: relative file path
## 2: md5sum
## 3: number of bytes
## 4: date/time md5sum was derived

🧩 verify-md5-manifest

Compares the current MD5 checksums of files in a test artifact directory with a saved manifest, reporting any mismatches or missing files.

Usage

verify-md5-manifest --test-case-dir <path> --manifest-file <path>

Example Output

✔ inputs/sample_input.vcf
✔ outputs/expected_output.tsv
✘ outputs/altered_output.tsv

2 of 3 files passed
Files with mismatched MD5 sums:
File: outputs/altered_output.tsv
Current MD5: 25a89f...
Previous MD5: 53754d...
