createMockInteraction

function in meocord/testing Since 4.0.0

createMockInteraction<T extends object>(
  Class: InteractionClass<T>,
  props?: MockProps<T>,
): DeepMocked<T>

createMockInteraction<T extends object>(
  Class: InteractionClass<T>,
  props: MockProps<WithCache<T, CacheType>> & OutsideServer,
): DeepMocked<WithCache<T, CacheType>>

Creates a mock instance of a discord.js class, such as an interaction, keeping its prototype so instanceof holds.

Use it for the interaction a test hands to invoke or dispatch. For a user, a message, a guild, a channel or a client, the dedicated factories fill in what discord.js would; for a type with no class, use createMock.

Parameters

Name	Type	Description
`Class`	`InteractionClass<T>`	The discord.js class to mock.
`props?`	`MockProps<T>`	Values for properties the class declares `readonly`; see `MockProps`.

Returns

DeepMocked<T>

Examples

TypeScript

import { expect } from 'vitest'

const interaction = createMockInteraction(ButtonInteraction, { customId: 'ticket/42/close' })
expect(interaction.isButton()).toBe(true)
await interaction.reply({ content: 'Closed.' })
expect(interaction.replied).toBe(true)
await expect(interaction.reply({ content: 'Again.' })).rejects.toThrow()

Parameters

Name	Type	Description
`Class`	`InteractionClass<T>`	The discord.js interaction class to mock.
`props`	`MockProps< WithCache<T, CacheType> > & OutsideServer`	The interaction's properties, with `guild: null`, `member: null` or a DM `channel`; see `MockProps`.

Returns

DeepMocked<WithCache<T, CacheType>>

Examples

TypeScript

import { expect } from 'vitest'

const command = createMockInteraction(ChatInputCommandInteraction, { channel: createMockChannel(DMChannel), guild: null })
expect(command.inGuild()).toBe(false)
