testertest*.py files and parses their stdout PASSED/FAILED output? The runner is the missing piece that explains why the output-based format exists.Date: 2026-05-29

The observations provide strong negative evidence: there is no orchestration script or CI job that invokes the testertest*.py files. The runner is not a missing piece of the puzzle — its absence *is* the answer.
1. No CI configuration — .github/ directory does not exist (findgithubactions returned "Directory not found"). No GitHub Actions, no other CI config files were found at the repo root.
2. No runner script — Grepping for subprocess.*tester|tester.*subprocess across the entire repo returned zero matches (grepsubprocesstester). No script spawns these files as subprocesses.
3. No test harness — Grepping for testertest|runtest|testrunner outside of .code-expert/topics.json returned zero matches (grepruntestsscript). There is no Makefile, run_all.sh, or similar orchestrator.
4. The files are self-contained — b-tree-storage-engine/testertestbtree.py (lines 193–200) has a if _name == 'main': block that calls every test function sequentially and ends with print("\nAll tests PASSED"). Each file is designed to be invoked directly: python testertest_btree.py.
The print("testbasicputget PASSED") convention (visible at lines 45, 71, 92, 117, 137, 150 of the btree tester) is for human consumption, not machine parsing. When you run python testertest_btree.py, you see a sequential log of which tests passed. If one fails, the assert aborts with a traceback before the corresponding PASSED line prints — so silence on a test name means failure.
This is distinct from the test*.py files (the pytest-compatible tests), which use standard assert without print statements and rely on pytest's own reporting. The testertest_*.py files exist as zero-dependency validation scripts — they need only Python and the implementation module, no test framework at all.
The .code-expert/topics.json entry at line 1987 hints at the origin: *"How the code-expert workflow generates testertest*.py files from specs."* These files appear to be generated artifacts from the code-expert build pipeline, designed as standalone smoke tests that any developer can run with nothing more than python.
The testertest*.py files are standalone scripts, not inputs to a test runner. The PASSED/FAILED output is a human-readable log, not a machine-parseable protocol. There is no runner because none is needed — python testertestfoo.py *is* the runner.
