[New-bugs-announce] [issue25347] assert_has_calls output is formatted inconsistently

[Robert Zimmerman]

New submission from Robert Zimmerman:

For longer lists of calls, the "Expected" list is printed all on one line while the "Actual" list is pprinted and on multiple lines. This makes it hard to do a visual compare of which calls are missing/incorrect.

Example:

    AssertionError: Calls not found.
    Expected: [call('bbbbbbbbbbbbbbbbbbbb'), call('bbbbbbbbbbbbbbbbbbbb'), call('bbbbbbbbbbbbbbbbbbbb'), call('bbbbbbbbbbbbbbbbbbbb'), call('bbbbbbbbbbbbbbbbbbbb'), call('bbbbbbbbbbbbbbbbbbbb'), call('bbbbbbbbbbbbbbbbbbbb')]
    Actual: [call('aaaaaaaaaaaaaaaaaaa'),
     call('aaaaaaaaaaaaaaaaaaa'),
     call('aaaaaaaaaaaaaaaaaaa'),
     call('aaaaaaaaaaaaaaaaaaa'),
     call('aaaaaaaaaaaaaaaaaaa'),
     call('aaaaaaaaaaaaaaaaaaa'),
     call('aaaaaaaaaaaaaaaaaaa')]


What I'd expect:

    AssertionError: Calls not found.
    Expected: [call('bbbbbbbbbbbbbbbbbbbb'),
     call('bbbbbbbbbbbbbbbbbbbb'),
     call('bbbbbbbbbbbbbbbbbbbb'),
     call('bbbbbbbbbbbbbbbbbbbb'),
     call('bbbbbbbbbbbbbbbbbbbb'),
     call('bbbbbbbbbbbbbbbbbbbb'),
     call('bbbbbbbbbbbbbbbbbbbb')]
    Actual: [call('aaaaaaaaaaaaaaaaaaa'),
     call('aaaaaaaaaaaaaaaaaaa'),
     call('aaaaaaaaaaaaaaaaaaa'),
     call('aaaaaaaaaaaaaaaaaaa'),
     call('aaaaaaaaaaaaaaaaaaa'),
     call('aaaaaaaaaaaaaaaaaaa'),
     call('aaaaaaaaaaaaaaaaaaa')]
