How to get longer Actual Sequence Output? #149

Closed alibabashack closed 5 years ago

alibabashack commented 5 years ago

When FakeIt (used from Catch2) outputs a list of actual invocations on mocks, then the list is truncated after some lines and dots (...) are added. I am unsure who limits the output, Catch or FakeIt. Any ideas how I can get a full list? Thanks! Example of truncated output:

tests/TrxPathIntegration.cpp:115: FAILED:
  Verify( listener.trxGroupStateChanged(01, 00) ... trxArray[0].startDispatch( Any arguments ) ... watchdogTimer.setTimeoutRelative(12345) ... trxArray[0].cancelDispatch( Any arguments ) ... trxArray[1].cancelDispatch( Any arguments ) ... watchdogTimer.setTimeoutRelative(735234) ... watchdogTimer.disable( Any arguments ) ... listener.trxGroupStateChanged(00, 01) )
with message:
  tests/TrxPathIntegration.cpp:115: Verification error
  Expected pattern: listener.trxGroupStateChanged(01, 00) ... trxArray[0].
  startDispatch( Any arguments ) ... watchdogTimer.setTimeoutRelative(12345) ..
  . trxArray[0].cancelDispatch( Any arguments ) ... trxArray[1].cancelDispatch(
  Any arguments ) ... watchdogTimer.setTimeoutRelative(735234) ...
  watchdogTimer.disable( Any arguments ) ... listener.trxGroupStateChanged(00,
  01)
  Expected matches: exactly 1
  Actual matches  : 0
  Actual sequence : total of 7 actual invocations:
    listener.trxGroupStateChanged(01, 00)
    trxArray[0].startDispatch(?)
    watchdogTimer.setTimeoutRelative(12345)
    trxArray[0].cancelDispatch()
    trxArray[1].cancelDispatch()
    ...

It is limited by FakeIt. The actual invocation list size can be huge hence we must limit the size of formatted output to some reasonable max number. I agree 5 may be too short. I changed it to 50. FakeIt will now print the first 50 actual invocations. Please pull the latest commit.

Thanks for the fast pragmatic fix. 50 invocations are fine for my current use case.
