Easy Test Setup without Side Effects

Givens is a testing utility designed to facilitate clean, maintainable, and side-effect-free test setups, primarily for JavaScript and TypeScript projects using Jest, Mocha, or Jasmine. Its behavior is inspired by RSpec's 'given' keyword, offering a familiar pattern for developers with Ruby backgrounds. The library helps prevent common testing pitfalls such as cross-contamination between tests, order-dependent tests, and unpredictable behavior when running subsets of tests (e.g., with `.only` or `.skip`). It achieves this by managing a cached, scoped value for 'given' variables, ensuring values are fresh for each test and correctly reverted across `describe` blocks. The current stable version is 1.3.9, with a recent cadence of security and dependency updates, indicating active maintenance rather than feature-heavy releases.
