Fake data

Basic usage

You can generate fake data, like person names, random integers, ... Useful for tests.

main_test.v

import khalyomede.mantis.http { create_app, App, Response, Request, Status }
import khalyomede.mantis.http.route
import khalyomede.mantis.test { expect, Fake }

const fake := Fake{}

fn test_it_returns_200_for_home_page() {
  content := fake.sentence()

  app := create_app(
    routes: [
      route.get(path: "/", callback: fn [content] (app App) !Response {
        return app.response.html(content: content)
      })
    ]
    request: Request{
      method: .get
      path: "/"
    }
  )

  res := app.render()

  expect(res.status).to_be_equal_to(Status.ok)
  expect(res.content).to_be_equal_to(content)
}

Custom data

The Fake struct data are called "generators". See the available generators section for a complete list.

You can create your own like this.

main_test.v

import khalyomede.mantis.test { expect }
import rand

struct Payment {}

fn (payment Payment) status() string {
  return rand.element(["pending", "validated", "rejected", "cancelled"]) or { "pending" }
}

struct Fake {
  test.Fake
  payment Payment
}

const fake := Fake{}

fn test_it_can_generate_payment_status() {
  status := fake.payment.status()

  expect(status).to_not_be_empty()
}
