Usage

import test from 'ava'
import parameterized from 'pava'
import { mySerialize, myDeserialize, myMax } from './my-code.js'

// Writing your test like this...
parameterized(
  test,
  `integer serializing and deserializing`,
  {
    zero: 0,
    negative: -4,
    positive: 5,
    large: 100000,
  },
  (t, integer) => {
    t.is(myDeserialize(mySerialize(integer)), integer)
  },
)

// Is the same as writing it like this!
test(`integer serializing and deserializing - zero`, t => {
  t.is(myDeserialize(mySerialize(0)), 0)
})
test(`integer serializing and deserializing - negative`, t => {
  t.is(myDeserialize(mySerialize(-4)), -4)
})
test(`integer serializing and deserializing - positive`, t => {
  t.is(myDeserialize(mySerialize(5)), 5)
})
test(`integer serializing and deserializing - large`, t => {
  t.is(myDeserialize(mySerialize(100000)), 100000)
})

// And writing your test like this...
parameterized(
  test,
  `integer serializing and deserializing`,
  [0, -4, 5, 100000],
  (t, integer) => {
    t.is(myDeserialize(mySerialize(integer)), integer)
  },
)

// Is the same as writing it like this!
// Note: the titles aren't as nice for large test case objects
test(`integer serializing and deserializing - 0`, t => {
  t.is(myDeserialize(mySerialize(0)), 0)
})
test(`integer serializing and deserializing - -4`, t => {
  t.is(myDeserialize(mySerialize(-4)), -4)
})
test(`integer serializing and deserializing - 5`, t => {
  t.is(myDeserialize(mySerialize(5)), 5)
})
test(`integer serializing and deserializing - 100000`, t => {
  t.is(myDeserialize(mySerialize(100000)), 100000)
})

// Destructure object literals to test functions with multiple parameters!
parameterized(
  test,
  `maximum of two integers`,
  {
    sameInteger: { first: 2, second: 2, expected: 2 },
    twoPositive: { first: 2, second: 3, expected: 3 },
    onePositiveOneNegative: { first: 2, second: -3, expected: 2 },
    twoNegative: { first: -2, second: -3, expected: -2 },
  },
  (t, { first, second, expected }) => {
    t.is(myMax(first, second), expected)
  },
)

// You can also use any ava test interface!
parameterized(test.serial /* ... */)
parameterized(test.failing /* ... */)
parameterized(test.only /* ... */)
parameterized(test.skip /* ... */)
parameterized(test.todo /* ... */)
// etc.
