Hi @metrue

As far as I know, there are two ways:

• Use edge-mock - https://github.com/samuelcolvin/edge-mock
• Use miniflare Jest Environment - https://miniflare.dev/testing/jest

edge-mock is used in benchmark/handleEvent. miniflare Jest Environment is used in example/blog

I tried both to test with FormData. minflare is better than edge-mock. miniflare reproduces Cloudflare Workers API faithfully. This tests will be passed:

  describe('FormData', () => {
    it('formData - application/x-www-form-urlencoded', async () => {
      app.post('/', async (c) => {
        const form = await c.req.formData()
        // console.log(c.req.headers.get('Content-Type'))
        // => application/x-www-form-urlencoded;charset=UTF-
        return c.text((form.get('aaa') || '').toString())
      })
      const searchParams = new URLSearchParams()
      searchParams.append('aaa', 'bbb')
      const req = new Request('https://localhost/', {
        method: 'POST',
        body: searchParams,
      })
      const res = await app.dispatch(req)
      expect(res.status).toBe(200)
      expect(await res.text()).toBe('bbb')
    })

    it('formData - multipart/form-data', async () => {
      app.post('/', async (c) => {
        const form = await c.req.formData()
        // console.log(c.req.headers.get('Content-Type'))
        // multipart/form-data; boundary=----formdata-undici-0.12093121571495491
        return c.text((form.get('aaa') || '').toString())
      })
      const formData = new FormData()
      formData.append('aaa', 'bbb')
      const req = new Request('https://localhost/', {
        method: 'POST',
        body: formData,
      })
      const res = await app.dispatch(req)
      expect(res.status).toBe(200)
      expect(await res.text()).toBe('bbb')
    })
  })
})

And, miniflare Jest Environment provides Environment. No need to call a method like makeServiceWorkerEnv().

Unfortunately, miniflare dump warning messages, but it will be resolved in the near future.

(node:73360) ExperimentalWarning: stream/web is an experimental feature. This feature could change at any time
(node:73360) ExperimentalWarning: buffer.Blob is an experimental feature. This feature could change at any time

I think miniflare Jest Environment is best. How about you?

Yes, miniflare Jest Environment is better, let's go with it.
