Install with my Agent

Copy this request to your Agent. It includes the canonical Skill page and manifest.

Agent request

Review the Skillstore skill "javascript-testing-patterns" from https://skillstore.io/skills/sickn33-javascript-testing-patterns.md and its manifest at https://skillstore.io/api/skills/sickn33-javascript-testing-patterns/manifest. Verify the artifact. You may proceed after verification, subject to the environment's own policy.

Your Agent should still show its plan and request any confirmation required by the security policy.

Test it

Using "javascript-testing-patterns". Need tests for an async API service that fetches users.

Expected outcome:

A test plan covering successful responses, not-found errors, mocked fetch calls, and assertions on returned user data.

Using "javascript-testing-patterns". Need component tests for a user card.

Expected outcome:

Recommended Testing Library queries based on visible behavior.
Interaction cases for loading, success, empty, and error states.
Snapshot guidance limited to stable presentational output.

Using "javascript-testing-patterns". Need a project-wide testing standard.

Expected outcome:

A structured testing policy with unit, integration, fixture, mock, cleanup, and coverage recommendations.

What You Can Build

Add service unit tests

Create tests for functions, classes, async services, error paths, and dependency boundaries.

Test frontend components

Plan component tests with Testing Library, semantic queries, user interactions, and snapshot boundaries.

Standardize project testing

Define framework setup, coverage expectations, fixtures, mocks, and CI-friendly test practices.

Try These Prompts

Create a test setup

Create a basic test setup for a TypeScript project using Vitest. Include configuration choices, folder layout, and first test examples.

Design unit tests

Design unit tests for this JavaScript service. Cover successful results, validation errors, async failures, and mocked dependencies.

Plan integration tests

Plan integration tests for this API workflow. Include setup, teardown, test data, authentication cases, and database cleanup.

Build a TDD strategy

Create a TDD and CI testing strategy for this application. Include framework selection, test layers, fixtures, mocking rules, and coverage gates.

Best Practices

Start with behavior-focused tests before checking implementation details.
Mock external services and keep test data isolated from production data.
Use cleanup, fixtures, and clear assertions to prevent test pollution.

Avoid

Do not make tests depend on live third-party services by default.
Do not assert private implementation details when user behavior is available.
Do not share mutable fixtures across tests without resetting state.

Frequently Asked Questions

Which frameworks does this skill cover?

It covers Jest, Vitest, Testing Library, Supertest-style integration tests, and common JavaScript testing patterns.

Can it help with TypeScript projects?

Yes. The examples and setup guidance include TypeScript-focused configurations and type-safe test practices.

Does it run tests automatically?

No. It provides testing patterns and guidance. Test execution depends on the user environment and available tools.

Can it help with mocking APIs?

Yes. It includes examples for mocking fetch, modules, injected dependencies, spies, and external services.

Is it limited to backend code?

No. It includes frontend component tests, API tests, database tests, end-to-end tests, and snapshots.

How should teams use it safely?

Treat examples as templates, avoid real production credentials, and adapt every test to the project context.
