tests

Rules for writing Vitest unit tests and Playwright integration tests for SAP UI5 code. They specify file patterns, test structure, mocks, coverage targets, waiting methods, and forbidden practices.

In plain words
What is it for?
Use them when creating or reviewing unit tests and browser integration tests, including test files, bridge mocks, UI5 waiting, assertions, and coverage.
Why use it?
They keep tests isolated and consistent while avoiding unreliable timing, unsafe types, hidden output, and untyped errors.

Getting it into your agent

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.

Made for: Cursor.

Per session 0 Nothing until a file matches its globs; then the whole rule loads.
When invoked 326 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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.

Security

Grade A, and why

tests 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 2d 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

Test Rules

Unit Tests (Vitest)

  • File pattern: *.test.ts
  • Hermetic: no network, no SAP system
  • Use describe / it pattern
  • Mock bridge with typed test doubles from tests/helpers/
  • Coverage ≥ 90% statements, ≥ 85% branches

Integration Tests (Playwright)

  • File pattern: *.spec.ts
  • Use test.step() for each logical step
  • NEVER use page.waitForTimeout() — use waitForUI5Stable()
  • Require SAP credentials in environment

Correct Pattern

import { describe, expect, it, vi } from 'vitest';

describe('MyModule', () => {
  it('should handle the expected case', () => {
    const result = myFunction(input);
    expect(result).toBe(expected);
  });

  it('should throw PramanError on failure', () => {
    expect(() => myFunction(badInput)).toThrow(PramanError);
  });
});

Forbidden in Tests

  • any type assertions
  • console.log (use test assertions)
  • page.waitForTimeout() (use waitForUI5Stable())
  • Raw throw new Error() (use typed error subclass)
  • require() in test source (ESM only)

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.

tests is a cursor rule published in the GitHub repository mrkanitkar/playwright-praman (11 stars, last pushed 6d ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 326 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 2026-08-30.
