Add Telegram API Tests
Workflow
1. Test Class Setup
- Extend BotTestContext (provides
bot, TG_ID, CHAT_ID, CHANNEL_ID)
- Use Kotest AnnotationSpec with
@Test suspend fun
- Test names: backtick string e.g.
`method name method test`
class MyApiTest : BotTestContext() {
@Test
suspend fun `my method test`() {
}
}
2. API Call Helpers
- Action (chat-based):
action.sendReq(to = TG_ID, via = bot) or action.sendReq(CHAT_ID)
- SimpleAction:
action.sendReq(via = bot) or action.sendReq()
- MediaAction: same as Action
- Defaults:
sendReq() uses TG_ID and bot when omitted
3. Assertions
- Success:
.shouldSuccess() - asserts ok, isSuccess, getOrNull not null
- Optional result:
.getOrNull() when success not guaranteed
- Failure:
.shouldFailure() - returns Response.Failure
- Error text:
response.shouldFailure() shouldContainInDescription "ERROR_TEXT"
4. Rate Limits (429)
For methods that may hit rate limits (e.g. setMyName):
val result = setMyName("test").sendReq()
result.onFailure { if (it.errorCode == 429) return }
result.shouldSuccess()
5. Test Placement
- Path:
telegram-bot/src/jvmTest/kotlin/eu/vendeli/api/
- Mirror API package:
botactions/, media/, message/, chat/, etc.
- Add to existing test class if one exists for that API area
6. Environment
Tests load from .env or system env. Required for most tests:
TELEGRAM_ID - your Telegram user IDBOT_TOKEN - bot token from BotFather
Optional:
CHAT_ID - for chat/group testsCHANNEL_ID - for channel testsBOT_TOKEN_2 - rate-limit testing
