In-Memory NetworkTables Diagnostic Harness

Build a small diagnostic harness that exercises NetworkTables entirely in-memory for testing, with an option to surface verbose diagnostics to the caller. The harness should expose simple read/write helpers for a specified table path and keep a retrievable log when verbose mode is on.

Capabilities

Start in-memory session

• Creating a diagnostic session starts NetworkTables without opening sockets and returns an object ready for table access. @test

Table read/write

• Writing multiple key/value pairs to a table path stores the data and the same values can be read back immediately. @test
• Clearing the session removes all previously written entries so later reads return an empty mapping. @test

Verbose diagnostics

• When verbose diagnostics are enabled, each write appends a human-readable message to an in-memory log that can be retrieved by the caller. @test
