A Karma plugin - adapter for Jasmine testing framework.

Last verified Sep 9, 2026 against karma-jasmine@5.1.0.

karma-jasmine ships CommonJS only. require("karma-jasmine") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >=12. import "karma-jasmine" also works because Node.js and Bun can import CommonJS from ES modules, but only the default export is guaranteed; named imports depend on Node's static analysis of the module.

## What to do

1. require("karma-jasmine") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >=12.
2. From ES modules use the default import: import karmaJasmine from "karma-jasmine"; then destructure. Named imports only work when Node.js can statically detect the exports.
3. TypeScript: npm install -D @types/karma-jasmine
