A set of project-specific testing rules for a sales-alert application. It defines shared test helpers, country configurations, and representative end-to-end cases.

Use it when writing or reviewing unit and end-to-end tests for the application's sale-fetching, filtering, notifications, and country-specific client behavior.

It prevents tests from creating inconsistent objects, using unsuitable country settings, or repeating equivalent cases. End-to-end testing checks complete workflows across representative configurations.

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00000	$0.00507
Opus 5	$0.00000	$0.00253
Sonnet 5	$0.00000	$0.00101
Haiku 4.5	$0.00000	$0.00051

Measured 7d ago against content hash 10ae9f901478, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-08, from the pricing page.

Security

Grade A, and why

testing scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Testing Conventions

Fixtures and helpers

Use sample_deal(**overrides) from conftest.py to build SaleItem objects. Never construct SaleItem(...) manually in tests.
Use _make_email_cfg(**overrides) for EmailChannelConfig in notification tests.
Use noop_verify() and noop_watched_fetch() from conftest to isolate filter/check tests from stock verification.
Use the module-level _mock_v3_empty() in test_uniqlo_client.py for v3 endpoint mocks.

Country configs in client tests

Tests for fetch_sale_products must use a country whose CountryCapabilities.listing_sources include the endpoints being tested:
- v5 discount only: de/de
- v5 discount + limitedOffer: id/en
- v3 + v5 mix: th/en
- sale_paths: sg/en (with sale_paths configured)

E2E country representatives

The e2e sweep tests one representative per distinct CountryCapabilities combination (listing_sources × stock_api × url_style). Countries within the same group share identical pipeline code paths.
- de/de — v5_disc only, stock_api=v5, display_code URLs (covers uk, fr, es, it, be, nl, dk, se, au, in, kr)
- id/en — v5_disc + v5_ltd, stock_api=v5, display_code URLs (covers vn, my, us, ca, jp)
- ph/en — v3_disc + v3_ltd, stock_api=none, code URLs
- th/en — v5_ltd + v3_disc + v3_ltd, stock_api=none, code URLs
- sg/en — v5_disc + sale_paths, stock_api=v5, display_code URLs
When adding a new country, check if its capabilities match an existing group. If not, add a new representative to _REPRESENTATIVE_COUNTRIES in test_e2e_html_preview.py.

Parametrize over copy-paste

When 3+ tests follow the same pattern with different inputs, use @pytest.mark.parametrize.
Example: SMTP error tests are parametrized, not duplicated.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

testing is a cursor rule published in the GitHub repository kequach/uniqlo-sales-alerter (30 stars, last pushed 17d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 507 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-01.
