Client Test Cases

This is a list of different test cases that client developers should apply to their code base.

Tool Suite

TODO: create and document an automated tool suite.

An ideal tool suite would be one of (or all of):

• A hosted component with well-defined JIDs exhibiting the test case behavior
• An XMPP component that can be self-hosted
• A set of bot scripts / tools that can connect to a given (set of) account(s)

Message Errors

A client should properly support the following cases:

1. A message is rejected by the other side - display error on message, show text message describing the failure in the details
2. A message is accepted by the other side (you receive a Receipt) - display normally or with an additional checkmark
3. A message is accepted (Receipt), then bounced (you receive an error) - the error is probably from a stale session and should be ignored - display checkmark
4. A message is bounced, then accepted - first display error, then checkmark

There is a hosted version of test 1. at xmpp:reject@yax.im

Multi User Chats

Joining

1. A join is not responded to at all by the MUC
2. A join is responded to with an error presence
3. The join response does not contain a subject
4. The join response does not contain a self-presence
5. The join response neither contains a subject nor a self-presence

Staying inside

1. The client gets kicked by the MUC, with or without a message
2. The client gets banned by the MUC, with or without a message
3. The MUC join completes, but the occupant is then silently removed, all subsequent messages get rejected (see XEP-0410)

Affiliation

1. The client gets muted by the MUC, with or without a message

Other

1. Another occupant sends an invalid presence to the room (I'm looking at you, old Gajim)

HTTP File Upload

A testing component could reject the file slot request IQ with different errors based on the requested file name / file size. A client developer would have a set of according files to trigger different conditions.
