Description Jonathan Druart 2019-05-16 00:43:22 UTC
After bug 21213 we wanted to know why Circulation.t was failing randomly on a given test.
Since it is pushed, it failed (at least) twice, with the same error:

    #   Failed test 'AddReturn must have debarred the patron'
    #   at t/db_dependent/Circulation.t line 3112.
    #          got: ''
    #     expected: '1'
    # AddReturn returned message $VAR1 = {
    #           'WasReturned' => 1
    #         };

    #   Failed test 'Test at line 1918'
    #   at t/db_dependent/Circulation.t line 3116.
    #          got: '0'
    #     expected: '1'

    #   Failed test 'Test at line 1918'
    #   at t/db_dependent/Circulation.t line 3119.
    #          got: undef
    #     expected: '2019-05-30'
    # Looks like you failed 3 tests of 21.

The test at line 3113 expects the flags 'WasReturned' and 'Debarred' to be set, but only WasReturned is.
Which means the patron has not been debarred. It is not because the checkout has not been detected as overdue.

Bug 22917: Prevent Circulation.t if tests ran too slowly

After bug 21213 we wanted to know why Circulation.t was failing randomly on a given test.
Since it is pushed, it failed (at least) twice, with the same error:

    #   Failed test 'AddReturn must have debarred the patron'
    #   at t/db_dependent/Circulation.t line 3112.
    #          got: ''
    #     expected: '1'
    # AddReturn returned message $VAR1 = {
    #           'WasReturned' => 1
    #         };

    #   Failed test 'Test at line 1918'
    #   at t/db_dependent/Circulation.t line 3116.
    #          got: '0'
    #     expected: '1'

    #   Failed test 'Test at line 1918'
    #   at t/db_dependent/Circulation.t line 3119.
    #          got: undef
    #     expected: '2019-05-30'
    # Looks like you failed 3 tests of 21.

The test at line 3113 expects the flags 'WasReturned' and 'Debarred' to be set,
but only WasReturned is.
Which means the patron has not been debarred. It is not because the checkout has
not been detected as overdue.

If you apply only the first patch you will see that the tests are failing with
the exact same failures.
Indeed, if due_date is not passed to test_debarment_on_checkout, it is set to now (dt_from_string).
However, if the call and the test of the parameters inside the subroutine takes
more than 1 second,
then due_date will be after what we really expect. To reproduce that, we add
1 minute to due_date and we observe the tests failing.

The trick here (and we should have in all our tests) is to mock
DateTime->now to make sure dt_from_string will always return the same
value, it is what we expect from our tests (in 99.9% of the cases at
least).

Bug 22917: Fix more funky things

And that's where a land.

We are making another test failing much more often than before.
The 'now' mocked will be far before the now() of mysql from the tests
executed at the end of Circulation.t
Without this patch I get the following error one out of the two runs:
    #   Failed test 'renew log successfully added'
    #   at t/db_dependent/Circulation.t line 3024.
    #          got: '4'
    #     expected: '5'
    # Looks like you failed 1 test of 13.

Using the mocked value will solve this issue.
I cannot find any side-effects this change could cause.

Bug 22917: Fix a typo in an output_pref call

Due to a type in a call to output_pref (datenonly vs dateonly) we were
comparing logactions within a minutes accuracy. Counting the logs for
the day would be sufficient for the test ;)
Comment 6 Martin Renvoize (ashimema) 2019-05-16 15:58:12 UTC
I've replaced the final patch with an alternative that fixes the typo in the test rather than altering the behaviour of C4::Log::logaction.
