17.4 For each real-time text (RTT) functionality, can the messages be identified (excluding special cases)?

Official methodology to test criterion 17.4

Test 1 (17.4.1)

  1. Activate the web application and the application's real-time text (RTT) functionality on two terminals and connect them to the same session.
  2. Send a text message from both terminals to obtain messages with different statuses (sent and received).
  3. Check that
    • sent and received messages are visually separated (for example, sent messages are in one window and received messages in another, or there is a line break between each received and sent message if they are presented in the same window);
    • it is visually possible to distinguish between messages sent and messages received. For example, by a layout or colour that differentiates them or by a visible text annotation (look for the words "Sent" near a message that has been sent or "Received" near a message that has been received);
    • information about the nature of the message (received or sent) is accessible to assistive technologies (text information is available to provide this information).
  4. If this is the case, the test is validated.

Test 2 (17.4.2)

  1. Activate the web application and the application's real-time text (RTT) functionality on two terminals and connect them to the same session.
  2. Send a written message from both terminals to get messages from different authors.
  3. Check that the authors of the text messages are identified (for example, the presence of a name or identifier preceding the message).
  4. If this is the case, the test is validated.
