Add automated test (python) for irreversible mode

[andriantolie]

Change Description

Add automated test (python) for the irreversible mode (#6704) which encompasses the following 8 test cases:

• 1st test case: Replay in irreversible mode with reversible blks

  • Expectation: Node replays and launches successfully with head == libBeforeSwitchMode == lib and forkDbHead == headBeforeSwitchMode == forkDbHeadBeforeSwitchMode
  • Current Bug: duplicate blk added error

• 2nd test case: Replay in the irreversible mode without reversible blks

  • Expectation: Node replays and launches successfully with head == libBeforeSwitchMode == lib and forkDbHead == headBeforeSwitchMode == forkDbHeadBeforeSwitchMode
  • Current Bug: lib != libBeforeSwitchMode

• 3rd test case: Switch mode speculative -> irreversible without replay

  • Expectation: Node switches mode successfully with head == libBeforeSwitchMode == lib and forkDbHead == headBeforeSwitchMode == forkDbHeadBeforeSwitchMode
  • Current Bug: head != lib

• 4th test case: Switch mode irreversible -> speculative without replay

  • Expectation: Node switches mode successfully with head == forkDbHeadBeforeSwitchMode == forkDbHead and lib == headBeforeSwitchMode == libBeforeSwitchMode
  • Current Bug: head != forkDbHead and head != forkDbHeadBeforeSwitchMode and lib != libBeforeSwitchMode

• 5th test case: Switch mode speculative -> irreversible without replay and connected to producing node

  • Expectation: Node switches mode successfully and the head and lib should be advancing after some blocks produced with head == libBeforeSwitchMode == lib and forkDbHead == headBeforeSwitchMode == forkDbHeadBeforeSwitchMode
  • Current Bug: Fail to switch to irreversible mode, blk_validate_exception next blk in the future will be thrown

• 6th test case: Switch mode irreversible -> speculative without replay and connected to producing node

  • Expectation: Node switches mode successfully and the head and lib should be advancing after some blocks produced with head == forkDbHeadBeforeSwitchMode == forkDbHead and lib == headBeforeSwitchMode == libBeforeSwitchMode
  • Current Bug: Node switches mode successfully, however, it fails to establish connection with the producing node

• 7th test case: Replay in the irreversible mode with reversible blks while production is enabled

  • Expectation: Node replays and launches successfully and the head and lib should be advancing after some blocks produced with head == libBeforeSwitchMode == lib and forkDbHead == headBeforeSwitchMode == forkDbHeadBeforeSwitchMode
  • Current Bug: duplicate blk added error

• 8th test case: Replay in irreversible mode without reversible blks while production is enabled

  • Expectation: Node replays and launches successfully and the head and lib should be advancing after some blocks produced with head == libBeforeSwitchMode == lib and forkDbHead == headBeforeSwitchMode == forkDbHeadBeforeSwitchMode
  • Current Bug: Nothing
