Context and config builders for testing.

Provides functions to create bot.Context, config.Config, and bot.SessionSettings with sensible test defaults.

let ctx = context.context(session: MySession(count: 0))
let cfg = context.config()

Values

catch_handler

</>

pub fn catch_handler() -> fn(
  bot.Context(session, error, dependencies),
  error,
) -> Result(Nil, error)

Creates a no-op catch handler.

config

</>

pub fn config() -> @internal Config

Creates a test Config with a test token and URL.

config_with_client

</>

pub fn config_with_client(
  client: client.TelegramClient,
) -> @internal Config

Creates a test Config with the given Telegram client. Use this with mock.message_client() to get a config that returns valid API responses.

context

</>

pub fn context(
  session session: session,
) -> bot.Context(session, error, Nil)

Creates a Context with the given session and default update/config.

dependencies defaults to Nil. To inject mock services, use context_with_dependencies (or context_with_all).

context_with

</>

pub fn context_with(
  session session: session,
  update update: update.Update,
) -> bot.Context(session, error, Nil)

Creates a Context with the given session and update. dependencies defaults to Nil.

context_with_all

</>

pub fn context_with_all(
  session session: session,
  update update: update.Update,
  key key: String,
  bot_info bot_info: types.User,
  dependencies dependencies: dependencies,
) -> bot.Context(session, error, dependencies)

Creates a Context with full customization, including injected dependencies.

context_with_dependencies

</>

pub fn context_with_dependencies(
  session session: session,
  dependencies dependencies: dependencies,
) -> bot.Context(session, error, dependencies)

Creates a Context with the given session and mock dependencies (services).

Use this to substitute mocked services in handler tests: context.context_with_dependencies(session: MySession(..), dependencies: MockDependencies(db:, http:)).

session_settings

</>

pub fn session_settings(
  default default: fn() -> session,
) -> bot.SessionSettings(session, error)

Creates SessionSettings with a no-op persist and get returning None.

session_settings_with

</>

pub fn session_settings_with(
  default default: fn() -> session,
  initial initial: session,
) -> bot.SessionSettings(session, error)

Creates SessionSettings where get returns Some(initial).
