Use the transport from the class, and make a new session instance.
Suggested change
| transport = new MockMcpClientTransport(); | |
| session = new McpClientSession(TIMEOUT, transport, Map.of(testMethod, failingHandler), Map.of()); | |
| var session = new McpClientSession(TIMEOUT, transport, Map.of(testMethod, failingHandler), Map.of()); |
Goes for all tests.
