I am using Test::More to test a function that produces error messages (which are quite long - don't get distracted by the content of the one tested here!) Here, I am simply testing whether the output looks as it should:

is( $returned_message, $expected, 'expected_error_message');

As far as I am concerned, the output looks right, but is says it isn't.

I am sure this must be some very stupid oversight on my part, but I can't seem to figure out where. If you have a look at this snippet of output:

not ok 8 - expected_error_message
#   Failed test  'expected_error_message'
#          got: '
# esis2sth: Fatal runtime error triggered in #testelement->#testevent
#    Bad thing
#    What triggered this in your code should be in this line in foo.es
+s:
#    11        Line 11 of the code
#    [Input from: test.sgml, line 127]
# '
#     expected: '
# esis2sth: Fatal runtime error triggered in #testelement->#testevent
#    Bad thing
#    What triggered this in your code should be in this line in foo.es
+s:
#    11        Line 11 of the code
#    [Input from: test.sgml, line 127]
# '

can you indentify any difference between got and expected?

It's not only that I cannot see the difference between got and expected, but I have also tried copying the strings between the single quotes into files and then diff'ing these files: no difference.

I am new to testing (but not to Perl), so I hope this problem is somehow familiar to somebody...

Many thanks for any help!!
