test-patterns

A collection of patterns for testing Selenium-based Python applications with pytest, a Python testing tool. It covers arranging tests, running them with different data, grouping them, handling failures, and checking performance.

In plain words
What is it for?
Use it when writing Selenium tests with pytest, especially tests that cover multiple user types, reusable fixtures, expected failures, and performance checks.
Why use it?
It provides a consistent structure for browser tests, making authentication and other user-flow checks easier to organize and repeat.

Cursor rule for Cursor

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 2,177 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

test-patterns 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.

Selenium Python Test Patterns

Advanced Test Structure

  • Arrange-Act-Assert Pattern: Clear test structure with setup, action, and verification
  • Data-Driven Testing: Parametrized tests with comprehensive data coverage
  • Test Categorization: Smart use of pytest markers for test organization
  • Robust Error Handling: Graceful failure management and recovery

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.

test-patterns is a cursor rule published in the GitHub repository tugkanboz/awesome-cursorrules (20 stars, last pushed 3d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 2,177 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.
