Initialize Bun Test

Set up bun test for this project.

Steps

1. Detect if Effect project:

   • Check package.json for effect dependency

2. Create bunfig.toml:

   Standard project:

   [test]
   root = "./src"
   testMatch = ["**/*.test.ts"]
   

   Effect project:

   [test]
   root = "./src"
   testMatch = ["**/*.test.ts"]
   

3. Install test dependencies:

   Standard project:

   bun add -D @types/bun
   

   Effect project:

   bun add -D @types/bun @codeforbreakfast/bun-test-effect
   

4. Add scripts to package.json:

   "test": "bun test",
   "test:watch": "bun test --watch"
   

5. Create example test file (if no tests exist):

   Standard (src/example.test.ts):

   import { describe, expect, it } from 'bun:test'
   
   describe('example', () => {
     it('works', () => {
       expect(1 + 1).toBe(2)
     })
   })
   

   Effect (src/example.test.ts):

   import { describe, expect, it } from '@codeforbreakfast/bun-test-effect'
   import { Effect } from 'effect'
   
   describe('example', () => {
     it('works', () => {
       expect(1 + 1).toBe(2)
     })
   
     it.effect('works with Effect', () =>
       Effect.gen(function* () {
         const result = yield* Effect.succeed(42)
         expect(result).toBe(42)
       })
     )
   })
   

6. Run tests to verify setup:

   bun test
   

Ask before creating example test file if tests already exist.
