description

Fully autonomous QA testing agent for Modular RAG MCP Server. Reads test cases from QA_TEST_PLAN.md, executes ALL test types automatically without human intervention — CLI commands, Dashboard UI via Streamlit AppTest headless rendering, MCP protocol via subprocess JSON-RPC, provider switches, and data lifecycle checks. Diagnoses failures, applies fixes with up to 3 retry rounds, and records results in QA_TEST_PROGRESS.md. Use when user says 'run QA', 'QA test', 'QA 测试', '执行测试', '跑测试', 'test and fix', or wants to execute QA test plan.

QA Tester

All test types (CLI / Dashboard UI / MCP protocol) are fully automated — zero human intervention.

Optional modifiers: append section letter (run QA G) or test ID (run QA G-01).

⛔ IRON RULES

Rule 1: STRICTLY SERIAL

Pick ONE test → Run ONE command → Wait for output → Record ONE row in QA_TEST_PROGRESS.md → THEN pick next. NEVER run two tests in one command. NEVER record two rows in one file edit. NEVER use parallel tool calls. NEVER plan the next test before recording the current one.

Rule 2: PASS = TERMINAL OUTPUT EVIDENCE

✅ means you ran a command in THIS session and the Note contains concrete values copied from that output. No terminal output for THIS test → mark ⬜. NEVER ✅.

Rule 3: ZERO CROSS-REFERENCING

NEVER write "Verified via X-YZ", "Already verified in C-02", "Same as…", "Similar to…". Even if G-05 tests the same flag as C-02, run G-05 independently and paste its own output.

Rule 4: ZERO INFERENCE

BANNED Note patterns (caught by validator): "Code uses…" / "Dataclass validates…" / "auto-creates…" → Reading code ≠ testing. "Should work…" / "Would raise…" / "Expected behavior…" → Speculation ≠ testing. "Parameter accepted" / "Config controls behavior" → Vague. No output = no pass. If you didn't run a command and see output for THIS test, mark ⬜.

Rule 5: ADVERSARIAL MINDSET

Find bugs, not confirmations. 10+ passes with zero bugs → re-examine your rigor.

Rule 6: SECTION-END VALIDATION

After completing a section, run python .claude/skills/qa-tester/scripts/qa_validate_notes.py. Re-execute any flagged test before moving to next section.

---

Pipeline (strictly serial)

1. Pick ONE pending test (by ID order)
2. Set system state if needed
3. Run ONE command — WAIT for output
4. Verify ALL assertions from Expected Result vs ACTUAL output
5. Fix if needed (≤3 rounds)
6. ⛔ GATE: Edit QA_TEST_PROGRESS.md (row + counters) — ONE row per edit
7. Only NOW return to step 1

Activate .venv before any python command: .\.venv\Scripts\Activate.ps1

---

Step 1: Pick Target

1. Read QA_TEST_PLAN.md for test steps and expected results.
2. Read QA_TEST_PROGRESS.md for current status.
3. User-specified section/ID → scope to that. Otherwise → first ⬜ pending test.
4. If any 🔧 tests exist, re-test those first.
5. Execute in section order (A→O), within section in ID order.

Test Categories

Sections	Type	Execution Method
A–F	Dashboard UI	AppTest headless — see references/test_patterns.md
G, H, I	CLI	Terminal commands, check exit code + stdout
J	MCP Protocol	JSON-RPC subprocess — see references/test_patterns.md
K, L	Provider Switch	qa_config.py apply <profile> → run CLI/Dashboard
M	Config & Fault Tolerance	Modify settings → run CLI → verify error handling
N, O	Data Lifecycle	Use qa_multistep.py <TEST_ID>

---

Step 2: Set System State

Empty          → python .claude/skills/qa-tester/scripts/qa_bootstrap.py clear
Baseline       → python .claude/skills/qa-tester/scripts/qa_bootstrap.py baseline
DeepSeek       → python .claude/skills/qa-tester/scripts/qa_config.py apply deepseek
Rerank_LLM     → python .claude/skills/qa-tester/scripts/qa_config.py apply rerank_llm
NoVision       → python .claude/skills/qa-tester/scripts/qa_config.py apply no_vision
InvalidKey     → python .claude/skills/qa-tester/scripts/qa_config.py apply invalid_llm_key
InvalidEmbedKey→ python .claude/skills/qa-tester/scripts/qa_config.py apply invalid_embed_key
Any            → no state change needed

After config-profile tests → python .claude/skills/qa-tester/scripts/qa_config.py restore Check state → python .claude/skills/qa-tester/scripts/qa_bootstrap.py status

---

Step 3: Execute & Verify

CLI Tests (G, H, I, parts of K/L/M)

1. Read the test's Steps column from QA_TEST_PLAN.md.
2. Run the exact command in terminal.
3. Compare output against Expected Result:
   • Ingest: exit=0, output has stage names (load/split/transform/embed/upsert)
   • Query: exit=0, results have source_file and score
   • Error: exit≠0, stderr has descriptive error (not raw stack trace)
   • Idempotency: second run shows "skipped", no duplicates

Dashboard Tests (A–F)

Read references/test_patterns.md for AppTest templates, interaction patterns, and file upload workarounds.

Key points:

• Write one inline Python script per test, render via AppTest.from_function
• Print specific element values (metric labels, selectbox options, expander labels)
• For file uploads: ingest via CLI first, verify via AppTest
• For data mutations: call DataService directly, verify via AppTest/CLI

⚠️ AppTest st.tabs() Limitation — MUST READ before testing any tab content

AppTest renders all tab contents simultaneously into a flat element list. There is no spatial isolation between tabs — you cannot determine which element belongs to which tab from at.info, at.metric, at.markdown etc.

Consequence: If a test step says "click tab X → see content Y inside tab X", AppTest cannot confirm the spatial relationship. Even if content Y exists in the output, it may come from a different region (e.g., a diagnostics area above the tabs, or a different tab).

Mandatory check for ALL tab-content tests:

1. First verify the tab label exists: Print [t.label for t in at.tabs] (if at.tabs is available) OR check the page source for the tab label string. If the expected tab label is absent → mark ❌ immediately — the tab does not exist.
2. Then verify the content element exists in the AppTest output.
3. Acknowledge the limitation in the Note: Append [AppTest: tab isolation unverifiable] to the Note.

Example — tab does NOT exist:

# For a test expecting "🟪 Rerank" tab with "skipped" message:
tab_labels = [el.value for el in at.markdown if '🟪' in el.value or 'Rerank' in el.value]
print('Rerank tab label found:', tab_labels)
# If empty → tab absent → mark ❌ with note "Rerank tab not rendered (stage absent)"

BANNED pattern: Finding a content element (e.g., "Rerank skipped" info) and concluding the tab test PASSED — the element may be from a diagnostics region, not from inside the tab.

MCP Tests (J)

Read references/test_patterns.md for JSON-RPC script template and assertion matrix.

Primary method: pytest tests/e2e/test_mcp_client.py -v covers most J-* cases.

Multi-Step Tests (N, O, M config, L-07)

Tests with 3+ sequential steps MUST use the runner script:

python .claude/skills/qa-tester/scripts/qa_multistep.py <TEST_ID>

Supported: N-01, N-03, N-04, N-05, N-06, O-07, M-03, M-04, M-05, M-06, M-10, M-11, L-07

The script executes every sub-step, prints ACTUAL values at each step, outputs VERDICT: PASS/FAIL. Copy the VERDICT and key step values into the Note.

For tests NOT in the script, run commands from QA_TEST_PLAN.md manually and paste output.

---

Step 4: Fix & Retry (≤3 rounds)

1. Diagnose: code bug / config issue / missing data / test plan error?
2. Fix: minimal change only. Record file/line in Note.
3. Retry: re-run same command.
4. After 3 failed rounds → mark ❌ with detailed notes.
5. If fix touches shared code → re-run previously-passed tests in same section.

---

Step 5: Record Results

⛔ GATE — do this BEFORE picking the next test.

Edit QA_TEST_PROGRESS.md: update ONE test row + summary counters. ONE row per file edit.

✅ PASS Requirements

All must be true:

1. Ran the command in this session
2. Observed actual output from that command
3. Verified every assertion in Expected Result
4. Note contains ≥2 concrete values from terminal output

Note Format

<method>: <value_1>, <value_2>[, ...]

• CLI: exit=0, stdout: 'Total chunks: 3', source_file=simple.pdf
• AppTest: at.metric[0].label='Total traces', at.metric[0].value=6
• Multi-step: Step1: exit=0, chunks=3. Step2: sources=[simple.pdf]. Step3: deleted=1. Step4: sources=[]
• Bad (BANNED): "Already verified in C-02", "Code uses yaml.safe_load", "Should work because...", "Parameter accepted"

Status Icons

Icon	Meaning
✅	Pass — all assertions verified against actual output
❌	Fail — failed after 3 fix attempts
⏭️	Skip — missing third-party API key (K-series only)
🔧	Fix applied — needs re-test
⬜	Pending — not yet tested

Counters

Update in the same edit: ✅ Pass: X | ❌ Fail: Y | ⏭️ Skip: Z | 🔧 Fix: W | ⬜ Pending: P (must sum to Total).

Section-End Gate

After each completed section:

python .claude/skills/qa-tester/scripts/qa_validate_notes.py

Re-execute any flagged test. Do NOT proceed until 0 flags.
