Overview

Generate unit tests for a .NET service following the coverage-kit conventions. Use when the user asks to 'generate tests', 'backfill tests', 'characterize this service', or 'add tests for' a target after coverage-init has run. Operates in characterization mode (freeze current behavior for existing code) or spec mode (assert intended behavior for new/changed code), enforces the run-capture-fill loop, routes untestable units to the manifest cannot-test log, can fan the backfill out across a user-chosen number of parallel agents for large worklists (asking first, since more agents cost more tokens), and runs a single read-only suite critique before the baseline locks in (auditing cannot-test legitimacy, assertion/C1 depth, systematic gaps, and any frozen defect missing from the manifest latent_bugs backlog, never the C0/C1 numbers themselves).

generate-tests

Generates tests under the base rules and this repo's overlay + manifest. Read all three before generating:

  • ${CLAUDE_PLUGIN_ROOT}/rules/unit-testing.base.md
  • .claude/coverage/refs/unit-testing.md (repo overlay)
  • .claude/coverage/refs/coverage-manifest.yml (categories, exclusions, gate)

Preflight: is this repo on the current kit?

Run this before building the worklist, every time, whether or not anyone mentioned an upgrade:

python .claude/coverage/tools/coverage-gate.py \
  --manifest .claude/coverage/refs/coverage-manifest.yml --print-kit-drift

Any state other than current means the repo has not been reconciled against today's rules, and a backfill is the worst moment to discover that: a pass run on superseded mechanics wastes every token it spends. Consult ${CLAUDE_PLUGIN_ROOT}/MIGRATIONS.md ("Preflight") and split what you find:

  • auto entries governing how THIS pass runs (refresh the .claude/coverage/tools/ copies, the fan-out contract, frozen-bug recording): apply them now, silently, and note them in the closing summary.
  • sign-off entries (anything that moves scope, the denominator, or the floor): report them in one line and leave them alone. Re-scoping mid-backfill moves the worklist under your own feet. coverage-redo is what applies them; say so and carry on with the pass as scoped today.

If the state is current, say nothing and continue.

Build the full worklist first — then cover ALL of it (do not stop early)

The scope of a backfill pass is the entire testable set the manifest defines, not a handful of "priority" files. Before writing any test, enumerate that set explicitly from the manifest and write it down as a checklist. The testable set is:

  1. Every file matched by a category_map target category and not matched by an exclusions pattern (the genuine unit-scope files), AND
  2. Every carve-out method on an exclusion entry: the structured carve_outs: list (each { method, lines, testable }), or the legacy CARVE-OUT: MethodA, MethodB prose in reason on older manifests. These are the thin pure/decision slices of god-classes (the UserService pattern): testable units even though their file is integration-scope, and a DbContext-injected service is tested by backing the context with the EF in-memory / SQLite provider. Init recorded them precisely so this step covers them; the file's excluded_rest says what stays out of scope.

Resolve every worklist item to a full repo-relative path, not a basename. Repos have many files sharing a name (UserService.cs, Handler.cs); test the exact file the manifest entry points at, mirror the test under that same path, and never carry one file's carve-out methods onto its same-named sibling. If a manifest pattern is ambiguous (bare basename matching several files), flag it back to the manifest rather than guessing which file it meant.

Items already covered by existing tests are checked off, not re-done. Items in cannot_test are out. Everything else in the set MUST be either tested in this backfill or appended to cannot_test with a reason — there is no third option of silently leaving it untouched.

An item is "done" only when its branches are covered — not when it has a green test. This is the definition that matters and the one most often shortcut. A method with filters, a switch, asc/desc, null guards or error paths needs an input pinned per branch; one happy-path test checks the item off the worklist while leaving 40–50% of its branches cold. A test existing is not the bar — its branches being exercised (or sent to cannot_test with a reason) is. Treat an under-covered target method exactly like an untested worklist item: not done. See "Cover the BRANCHES" below for how.

Hard rule: a coverage percentage is never a stopping condition — in either direction. Do not stop because the number "looks low" or "looks done," and do not stop at worklist completeness while target-layer methods still have uncovered branches. The pass ends only when every worklist item has branch-covered tests or a cannot_test entry. The classic failure this prevents: writing one test per file, watching the suite go green, and stopping at ~50–60% C0/C1 because each method got one path — that is an unfinished pass, not a complete one.

Phasing — when the worklist is large, plan it and report progress

If the worklist is large enough that one pass is impractical (rule of thumb: more than ~15 target files or ~40 carve-out methods, or it spans multiple test projects), do not silently do a slice and stop. Instead:

  1. Split the worklist into phases (group by file/service/test-project so each phase is a coherent, runnable chunk).
  2. Tell the user the phase plan up front — the full count of testable units, how many phases, and what each phase covers — before generating. This is the "let me know if it needs phases" contract.
  3. Execute phases in order. After each phase, report progress as N of M worklist items done and what remains. Keep going through all phases unless the user says otherwise.
  4. The working tree stays dirty across phases; do NOT commit between phases.

Scaling the backfill — efficiency, then optional parallel fan-out

A legacy worklist can be enormous. Two levers: make each unit cheaper, and (optionally) do many at once. The efficiency rules apply whichever way you run — sequential or parallel:

  1. Batch run-capture-fill per class, not per method. The dominant cost is build + test execution. Write the whole test class for a file — one test per branch of each method, not one test per method — build once, run the class once, capture all actual values from that single run, then fill. The economy is in batching the build/run, not in writing fewer tests: never pay a build/run cycle per method, and never trade away branch coverage to save cycles.

  2. Pre-triage narrows the assertion, it does not discard the unit. Before the write-build-run loop, scan each unit for an untestable signal (DateTime.Now/UtcNow, Guid.NewGuid, Random, direct infra/IO). A signal is a reason to look, not a verdict — a whole method is cannot_test only when the untestable condition is confirmed, not merely present:

    • Confirm "no seam." Is the dependency really un-mockable? A collaborator injected as an interface/abstract, an IHttpClientFactory, an optional Func<DateTime> — these are seams. A constructor-injected DbContext is also a seam: back it with the EF in-memory / SQLite provider. A DbContext on the constructor is NOT grounds to blanket-cannot_test the class; dumping every DbContext-touching method into cannot_test (as a real run did, roughly 87 false entries in one repo) is the canonical false-exclusion this rule exists to stop. Route to cannot_test only when the nondeterministic/infra call is made directly with no injectable seam, or when the specific EF op is one the in-memory provider cannot run (raw SQL, ExecuteUpdate/ExecuteDeleteAsync, Batch*, real transactions, unset-rowversion inserts, untranslatable LINQ).
    • Confirm the nondeterminism reaches the assertion. A method that logs DateTime.Now but returns a deterministic result is fully testable — assert the result. Only when the nondeterministic value flows into the output you would assert (and cannot be pinned) does that assertion drop. Named anti-pattern — the entry-line Stopwatch/Guid.NewGuid: event handlers and command handlers commonly open with var sw = new Stopwatch() / Guid.NewGuid() for timing and a correlation id used only in a log line. That is NOT the method's behavior — the behavior is the event→document/state mapping that follows. Do NOT route the whole handler to cannot_test for it; test the mapping/branches and ignore the log. Routing ~50 near-identical handlers to cannot_test on this signal (as a real run did) is the canonical false-exclusion this rule exists to stop.
    • Still cover the deterministic branches. A method with a Guid.NewGuid() id and three validation branches gets tests for the three branches (assert everything except the id, or assert the id is non-empty). cannot_test scopes to the specific method/assertion that is genuinely blocked — never the surrounding testable logic.

    When in doubt, run the loop — let run-capture-fill prove testability rather than pre-declaring it away to save a cycle. Every cannot_test entry you do record carries a mitigation (the seam that would unlock it), per the base rule.

  3. Pattern-replicate across siblings. Legacy services are full of structurally identical units (handlers, validators, mappers). Solve the seam/mock setup once on a representative, then replicate the shape across the lookalikes. A "phase 0" that builds the shared fixtures/builders once feeds this.

  4. Risk-order the worklist by complexity × churn × fan-in so the most valuable coverage lands first and the hardest seam problems surface early (while there is budget to fix them). This does not reduce total work — the worklist is still covered in full — it just sequences it well.

Optional parallel fan-out (ask the user first)

The worklist is independent per file, so it parallelizes cleanly. For a large worklist, offer to run the backfill as a fan-out workflow — but never auto-spawn agents. Parallel agents burn tokens fast, and the right count depends on how quickly the user wants it done and their budget, so present the trade-off and let them choose:

  1. Build and risk-order the full worklist (above). State the total count of testable units.
  2. Ask the user how many agents to run, mapping count to a rough wall-clock for this worklist (scale the examples to the real size; caveat that they are estimates and that more agents = proportionally more token burn):
    • 1 agent — sequential, lowest token burn, ~a day for a big service.
    • 3 agents (default) — balanced, ~6 hours.
    • 10 agents — fastest, highest burn, ~1 hour.
  3. On their choice, write the risk-ordered worklist to disk as a JSON array at coverage/backfill/worklist.json (each item shaped { file, methods?, group?, mode? }), then invoke the workflow with the manifest path, not the list itself. Get the call exactly right (each rule below is a real field failure this kit has hit, where ZERO agents ran and the launch still looked like success):
    • No item may live under a scope.vendored_paths directory. Those are copies of other repos' sources, owned and tested there. A worklist item inside one is a scoping bug upstream in the sweep, not work to do: drop it, and say so, rather than writing a test for another team's library against a copy the next vendoring sync overwrites. Filter the worklist against scope.vendored_paths before writing
