in incompatible ways.  It is otherwise stable.
.PP
Test::Harness is limited to printing out its results.  This makes
analysis of the test results difficult for anything but a human.  To
make it easier for programs to work with test results, we provide
Test::Harness::Straps.  Instead of printing the results, straps
provide them as raw data.  You can also configure how the tests are to
be run.
.PP
The interface is currently incomplete.  \fIPlease\fR contact the author
if you'd like a feature added or something change or just have
comments.

Analyzes the output of a single test, assigning it the given \f(CW$name\fR for
use in the total report.  Returns the \f(CW%results\fR of the test.  See
Results.

@test_output should be the raw output from the test, including newlines.

.Vb 1

.Ve
.Sp
Like \f(CW\*(C`analyze\*(C'\fR, but it runs the given \f(CW$test_file\fR and parses it's
results.  It will also use that name for the total report.

.IX Subsection "Results"
The \f(CW%results\fR returned from \fIanalyze()\fR contain the following information:
.PP
.Vb 2
\&  passing           true if the whole test is considered a pass 
\&                    (or skipped), false if its a failure
.Ve
.PP
.Vb 2
\&  exit              the exit code of the test run, if from a file
\&  wait              the wait code of the test run, if from a file
.Ve
.PP
.Vb 4
\&  max               total tests which should have been run
\&  seen              total tests actually seen
\&  skip_all          if the whole test was skipped, this will 
\&                      contain the reason.
.Ve
.PP
.Vb 2
\&  ok                number of tests which passed 
\&                      (including todo and skips)
.Ve
.PP
.Vb 3
\&  todo              number of todo tests seen
\&  bonus             number of todo tests which 
\&                      unexpectedly passed
.Ve
.PP
.Vb 1
\&  skip              number of tests skipped
.Ve
.PP
So a successful test should have max == seen == ok.
.PP
There is one final item, the details.
.PP
.Vb 2
\&  details           an array ref reporting the result of 
\&                    each test looks like this:
.Ve
.PP
.Vb 7
\&    $results{details}[$test_num - 1] = 
\&            { ok        => is the test considered ok?
\&              actual_ok => did it literally say 'ok'?
\&              name      => name of the test (if any)
\&              type      => 'skip' or 'todo' (if any)
\&              reason    => reason for the above (if any)
\&            };
.Ve
.PP
Element 0 of the details is test #1.  I tried it with element 1 being
#1 and 0 being empty, this is less awkward.
