The Subscription configuration in the CTT only supports a single "max subscriptions" parameter, while our server allows configuration of both a server-wide maximum and a per-session maximum.

Due to this limitation in CTT, certain tests may pass or fail depending on which maximum value we configure in CTT.

Our server configuration is as follows:

MaxSupportedSubscriptions (Server): 500
MaxSupportedSubscriptionsPerSession: 100

Here are examples of tests that are affected:

Subscription Base / Err-002:
    This test checks the maximum number of subscriptions supported per session.
    - Fail if we configure the server maximum (500), as the test only uses a single session.
    - Succeed if we configure the session maximum (100).

Subscription Publish Min 05 / 003:
    This test evaluates subscriptions across multiple sessions.
    - Succeed if we configure the server maximum (500), since multiple sessions are used.
    - Warning if we configure the session maximum (100). (CTT Warning: Not enough subscriptions for all sessions. Reducing session amount to 20)

The outcome of the tests is directly influenced by which configuration (server or session) is applied in the CTT, highlighting the need for more flexible configuration options in the tool.
