Mutation Tests stackslib/src/chainstate/stacks/boot/mod.rs > handle_pox_cycle_start_pox_2

Related #4587

The mutation testing highlighted there might be missing unit tests for handle_pox_cycle_start_pox_2 but there needs to be created a default for StacksTransactionEvent to check it.

The steps for making sure the handle_pox_cycle_start_pox_2 function has its possible outcomes caught are:

• create default for StacksTransactionEvent
• remove the skip header #[cfg_attr(test, mutants::skip)]
• check if mutation tests are caught for these cases:
  • run

  RUST_BACKTRACE=1 BITCOIND_TEST=1 cargo mutants -vV -F "replace StacksChainState::handle_pox_cycle_start_pox_2" -E ": replace .{1,2} with .{1,2} in " --baseline=skip --test-tool=nextest -- --run-ignored all --no-fail-fast --test-threads 1
  

  • Ok(vec![Default::default()])
• create tests if they aren't caught

Same flow for:

• handle_pox_cycle_start_pox_3
• handle_pox_cycle_start_pox_4
• handle_pox_cycle_missed_unlocks.
