Test::Harness::Straps(3perl) Perl Programmers Reference Guide Test::Harness::Straps(3perl)
NAME
Test::Harness::Straps - detailed analysis of test results
SYNOPSIS
use Test::Harness::Straps;
my $strap = Test::Harness::Straps->new;
# Various ways to interpret a test
my $results = $strap->analyze($name, \@test_output);
my $results = $strap->analyze_fh($name, $test_filehandle);
my $results = $strap->analyze_file($test_file);
# UNIMPLEMENTED
my %total = $strap->total_results;
# Altering the behavior of the strap UNIMPLEMENTED
my $verbose_output = $strap->dump_verbose();
$strap->dump_verbose_fh($output_filehandle);
DESCRIPTION
THIS IS ALPHA SOFTWARE in that the interface is subject to change in incompatible ways.
It is otherwise stable.
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.
The interface is currently incomplete. Please contact the author if you'd like a feature
added or something change or just have comments.
CONSTRUCTION
new()
my $strap = Test::Harness::Straps->new;
Initialize a new strap.
$strap->_init;
Initialize the internal state of a strap to make it ready for parsing.
ANALYSIS
$strap->analyze( $name, \@output_lines )
my $results = $strap->analyze($name, \@test_output);
Analyzes the output of a single test, assigning it the given $name for use in the total
report. Returns the $results of the test. See Results.
@test_output should be the raw output from the test, including newlines.
my $results = $strap->analyze_fh($name, $test_filehandle);
Like "analyze", but it reads from the given filehandle.
$strap->analyze_file( $test_file )
my $results = $strap->analyze_file($test_file);
Like "analyze", but it runs the given $test_file and parses its results. It will also use
that name for the total report.
Returns the full command line that will be run to test $file.
Returns the command that runs the test. Combine this with "_switches()" to build a
command line.
Typically this is $^X, but you can set $ENV{HARNESS_PERL} to use a different Perl than
what you're running the harness under. This might be to run a threaded Perl, for example.
You can also overload this method if you've built your own strap subclass, such as a PHP
interpreter for a PHP-based strap.
Formats and returns the switches necessary to run the test.
Returns only defined, non-blank, trimmed switches from the parms passed.
local $ENV{PERL5LIB} = $self->_INC2PERL5LIB;
Takes the current value of @INC and turns it into something suitable for putting onto
"PERL5LIB".
my @filtered_inc = $self->_filtered_INC;
Shortens @INC by removing redundant and unnecessary entries. Necessary for OSes with
limited command line lengths, like VMS.
$self->_restore_PERL5LIB;
This restores the original value of the "PERL5LIB" environment variable. Necessary on
VMS, otherwise a no-op.
Parsing
Methods for identifying what sort of line you're looking at.
my $is_diagnostic = $strap->_is_diagnostic($line, \$comment);
Checks if the given line is a comment. If so, it will place it into $comment (sans #).
my $is_header = $strap->_is_header($line);
Checks if the given line is a header (1..M) line. If so, it places how many tests there
will be in "$strap->{max}", a list of which tests are todo in "$strap->{todo}" and if the
whole test was skipped "$strap->{skip_all}" contains the reason.
my $is_bail_out = $strap->_is_bail_out($line, \$reason);
Checks if the line is a "Bail out!". Places the reason for bailing (if any) in $reason.
$strap->_reset_file_state;
Resets things like "$strap->{max}" , "$strap->{skip_all}", etc. so it's ready to parse the
next file.
EXAMPLES
See examples/mini_harness.plx for an example of use.
