Using the tests field

Each row includes a tests value containing a complete Bash test runner for that checkpoint. Save it as a file, then run it against a submission directory whose contents implement the entry file named in the instruction field.

Test script examples

Write and run one checkpoint from Python:

from pathlib import Path
import subprocess

from datasets import load_dataset

dataset = load_dataset("gabeorlanski/slopcodebench", "python", split="test")
row = dataset[0]

test_path = Path("test.sh")
test_path.write_text(row["tests"])
test_path.chmod(0o755)

subprocess.run(["bash", str(test_path), "/path/to/submission"], check=True)

Run a saved test script directly:

bash test.sh /path/to/submission

Use a local problems checkout to avoid cloning:

SCB_PROBLEMS_REPO=/path/to/scb-problems bash test.sh /path/to/submission

Keep the temporary workspace for debugging:

SCB_KEEP_WORKDIR=1 bash test.sh /path/to/submission

The runner creates a temporary workspace, copies the submission into it, materializes the relevant checkpoint tests and static assets, installs Python test dependencies in a virtual environment, and invokes pytest. Set SCB_PROBLEMS_REPO to an existing problems checkout to avoid cloning. Set SCB_KEEP_WORKDIR=1 to keep the temporary workspace for debugging.

For cpp, rust, and java subsets, the runner compiles the declared source file with g++, rustc, or javac before running the Python test harness. The js subset expects node to be available.
