Capturing log output in tests

1. Add this call at the top of the test
   Copy

   telemetry_subscribers::init_for_testing();
   

2. Run the test with the --nocapture (goes after --) command line flag (see https://doc.rust-lang.org/cargo/commands/cargo-test.html#display-options).
3. Optionally set the RUST_LOG (example RUST_LOG=debug) environment variable (defaults to info).

Debugging transactional tests in RustRover

1. Add new Cargo run configuration

2. 1. Command to run all tests
      Copy

      test -p sui-indexer-alt-e2e-tests --test transactional_tests
      

   2. Command to run single test (replace graphql/epochs/query.move with the test you want to run)
      Copy

      test -p sui-indexer-alt-e2e-tests --test transactional_tests graphql/epochs/query.move
      

   3. Note: debugging is not supported for nextest (https://youtrack.jetbrains.com/issue/RUST-12459)

3. To prevent error: invalid value 'json' for '--format <pretty|terse|json>' or error: unexpected argument '-Z' found, uncheck

   Copy

   RustRover -> Settings -> Advanced Settings -> Show test results in the Test tool window
   

   (https://youtrack.jetbrains.com/issue/RUST-7891/Cargo-test-bench-something-fails-with-unexpected-argument#focus=Comments-27-8478362.0-0)

4. To prevent FATAL: postmaster became multithreaded during startup in homebrew postgres15 server logs, set Environment Variables to LC_ALL=en_US.UTF-8.
