|

|
|
||
|
use Test::Builder::Tester tests => 1;
|
||
|
use Test::More;
|
||
|
|
||
|

=head1 DESCRIPTION
|
||
|
|
||
|
A module that helps you test testing modules that are built with
|
||
|
L<Test::Builder>.
|
||
|
|
||
|
The testing system is designed to be used by performing a three step
|
||
|
process for each test you wish to test. This process starts with using
|
||
|
C<test_out> and C<test_err> in advance to declare what the testsuite you
|
||
|
are testing will output with L<Test::Builder> to stdout and stderr.
|
||
|
|
||
|
You then can run the test(s) from your test suite that call
|
||
|
L<Test::Builder>. At this point the output of L<Test::Builder> is
|
||
|
safely captured by L<Test::Builder::Tester> rather than being
|
||
|
interpreted as real test output.
|
||
|
|
||
|
The final stage is to call C<test_test> that will simply compare what you
|
||
|
predeclared to what L<Test::Builder> actually outputted, and report the
|
||
|
results back with a "ok" or "not ok" (with debugging) to the normal
|
||
|
output.

|
|

|
=item test_out
|
||
|
|
||
|
=item test_err
|
||
|
|
||
|
Procedures for predeclaring the output that your test suite is
|
||
|
expected to produce until C<test_test> is called. These procedures
|
||
|
automatically assume that each line terminates with "\n". So
|
||
|
|
||
|
test_out("ok 1","ok 2");
|
||
|
|
||
|
is the same as
|
||
|
|
||
|
test_out("ok 1\nok 2");
|
||
|
|
||
|
which is even the same as
|
||
|
|
||
|
test_out("ok 1");
|
||
|
test_out("ok 2");
|
||
|
|
||
|
Once C<test_out> or C<test_err> (or C<test_fail> or C<test_diag>) have
|
||
|
been called, all further output from L<Test::Builder> will be
|
||
|
captured by L<Test::Builder::Tester>. This means that you will not
|
||
|
be able perform further tests to the normal output in the normal way
|
||
|
until you call C<test_test> (well, unless you manually meddle with the
|
||
|
output filehandles)
|
||
|
|
||
|

sub test_out {
|
||
|
# do we need to do any setup?
|
||
|
_start_testing() unless $testing;
|
||
|
|
||
|
$out->expect(@_);
|
||
|
}
|
||
|
|

sub test_err {
|
||
|
# do we need to do any setup?
|

_start_testing() unless $testing;

$err->expect(@_);
|
||
|
}
|
||
|
|
||
|
=item test_fail
|
||
|
|
||
|
Because the standard failure message that L<Test::Builder> produces
|
||
|
whenever a test fails will be a common occurrence in your test error
|
||
|
output, and because it has changed between Test::Builder versions, rather
|
||
|
than forcing you to call C<test_err> with the string all the time like
|
||
|
so
|
||
|
|
||
|
test_err("# Failed test ($0 at line ".line_num(+1).")");
|
||
|
|
||
|
C<test_fail> exists as a convenience function that can be called
|
||
|
instead. It takes one argument, the offset from the current line that
|
||
|
the line that causes the fail is on.
|
||
|
|
||
|
test_fail(+1);
|
||
|
|
||
|
This means that the example in the synopsis could be rewritten
|
||
|
more simply as:
|
||
|
|
||
|
test_out("not ok 1 - foo");
|
||
|
test_fail(+1);
|
||
|
fail("foo");
|
||
|
test_test("fail works");
|
||
|
|
||
|
=cut
|
||
|
|
||
|
sub test_fail {
|
||
|
# do we need to do any setup?
|
||
|
_start_testing() unless $testing;
|
||
|
|
||
|
# work out what line we should be on
|
||
|
my( $package, $filename, $line ) = caller;
|
||
|
$line = $line + ( shift() || 0 ); # prevent warnings
|
||
|
|
||
|
# expect that on stderr
|
||
|
$err->expect("# Failed test ($filename at line $line)");
|
||
|
}
|
||
|
|
||
|
=item test_diag
|
||
|
|
||
|
As most of the remaining expected output to the error stream will be
|
||
|
created by L<Test::Builder>'s C<diag> function, L<Test::Builder::Tester>
|
||
|
provides a convenience function C<test_diag> that you can use instead of
|
||
|
C<test_err>.
|
||
|
|
||
|
The C<test_diag> function prepends comment hashes and spacing to the
|
||
|
start and newlines to the end of the expected output passed to it and
|
||
|
adds it to the list of expected error output. So, instead of writing
|
||
|
|
||
|
test_err("# Couldn't open file");
|
||
|
|
||
|
you can write
|
||
|
|
||
|
test_diag("Couldn't open file");
|
||
|
|
||
|
Remember that L<Test::Builder>'s diag function will not add newlines to
|
||
|
the end of output and test_diag will. So to check
|
||
|
|
||
|
Test::Builder->new->diag("foo\n","bar\n");
|
||
|
|
||
|
You would do
|
||
|
|
||
|
test_diag("foo","bar")
|
||
|
|
||
|
without the newlines.
|
||
|
|
||
|
=cut
|
||
|
|
||
|
sub test_diag {
|
||
|
# do we need to do any setup?
|
||
|
_start_testing() unless $testing;
|
||
|
|
||
|
# expect the same thing, but prepended with "# "
|
||
|
local $_;
|
||
|
$err->expect( map { "# $_" } @_ );
|
||
|
}
|
||
|
|
||
|
=item test_test
|
||
|
|
||
|
Actually performs the output check testing the tests, comparing the
|
||
|
data (with C<eq>) that we have captured from L<Test::Builder> against
|
||
|
what was declared with C<test_out> and C<test_err>.
|
||
|
|
||
|
This takes name/value pairs that effect how the test is run.
|
||

|
||
|

|
||
|
|
||
|
=item title (synonym 'name', 'label')
|
||
|
|
||
|
The name of the test that will be displayed after the C<ok> or C<not
|
||
|
ok>.
|
||
|
|
||
|
=item skip_out
|
||
|
|
||
|
Setting this to a true value will cause the test to ignore if the
|
||
|
output sent by the test to the output stream does not match that
|
||
|
declared with C<test_out>.
|
||
|
|
||
|
=item skip_err
|
||
|
|
||
|
Setting this to a true value will cause the test to ignore if the
|
||
|
output sent by the test to the error stream does not match that
|
||
|
declared with C<test_err>.

As a convenience, if only one argument is passed then this argument
|
||
|
is assumed to be the name of the test (as in the above examples.)
|
||
|
|
||
|
Once C<test_test> has been run test output will be redirected back to
|
||
|
the original filehandles that L<Test::Builder> was connected to
|
||
|
(probably STDOUT and STDERR,) meaning any further tests you run
|
||
|
will function normally and cause success/errors for L<Test::Harness>.

|

|

A utility function that returns the line number that the function was
|
||
|
called on. You can pass it an offset which will be added to the
|
||
|
result. This is very useful for working out the correct text of
|
||
|
diagnostic functions that contain line numbers.
|
||
|
|
||
|
Essentially this is the same as the C<__LINE__> macro, but the
|
||
|
C<line_num(+3)> idiom is arguably nicer.

=item color
|
||
|
|
||
|
When C<test_test> is called and the output that your tests generate
|
||
|
does not match that which you declared, C<test_test> will print out
|
||
|
debug information showing the two conflicting versions. As this
|
||
|
output itself is debug information it can be confusing which part of
|
||
|
the output is from C<test_test> and which was the original output from
|
||
|
your original tests. Also, it may be hard to spot things like
|
||
|
extraneous whitespace at the end of lines that may cause your test to
|
||
|
fail even though the output looks similar.
|
||
|
|
||
|
To assist you C<test_test> can colour the background of the debug
|
||
|
information to disambiguate the different types of output. The debug
|
||
|
output will have its background coloured green and red. The green
|
||
|
part represents the text which is the same between the executed and
|
||
|
actual output, the red shows which part differs.
|
||
|
|
||
|
The C<color> function determines if colouring should occur or not.
|
||
|
Passing it a true or false value will enable or disable colouring
|
||
|
respectively, and the function called with no argument will return the
|
||
|
current setting.
|
||
|
|
||
|
To enable colouring from the command line, you can use the
|
||
|
L<Text::Builder::Tester::Color> module like so:
|
||
|
|
||
|
perl -Mlib=Text::Builder::Tester::Color test.t
|
||
|
|
||
|
Or by including the L<Test::Builder::Tester::Color> module directly in
|
||
|
the PERL5LIB.

=head1 BUGS
|
||
|
|
||
|
Test::Builder::Tester does not handle plans well. It has never done anything
|
||
|
special with plans. This means that plans from outside Test::Builder::Tester
|
||
|
will effect Test::Builder::Tester, worse plans when using Test::Builder::Tester
|
||
|
will effect overall testing. At this point there are no plans to fix this bug
|
||
|
as people have come to depend on it, and Test::Builder::Tester is now
|
||
|
discouraged in favor of C<Test2::API::intercept()>. See
|
||
|
L<https://github.com/Test-More/test-more/issues/667>
|
||
|
|
||
|
Calls C<< Test::Builder->no_ending >> turning off the ending tests.
|
||
|
This is needed as otherwise it will trip out because we've run more
|
||
|
tests than we strictly should have and it'll register any failures we
|
||
|
had that we were testing for as real failures.
|
||
|
|
||
|
The color function doesn't work unless L<Term::ANSIColor> is
|
||
|
compatible with your terminal. Additionally, L<Win32::Console::ANSI>
|
||
|
must be installed on windows platforms for color output.
