NAME Test::Script - Basic cross-platform tests for scripts VERSION version 1.27 SYNOPSIS use Test2::V0; use Test::Script; script_compiles('script/myscript.pl'); script_runs(['script/myscript.pl', '--my-argument']); program_runs(['ls', '/dev']); done_testing; DESCRIPTION The intent of this module is to provide a series of basic tests for 80% of the testing you will need to do for scripts in the script (or bin as is also commonly used) paths of your Perl distribution. It also provides similar functions for testing programs that are not Perl scripts. Further, it aims to provide this functionality with perfect platform-compatibility, and in a way that is as unobtrusive as possible. That is, if the program works on a platform, then Test::Script should always work on that platform as well. Anything less than 100% is considered unacceptable. In doing so, it is hoped that Test::Script can become a module that you can safely make a dependency of all your modules, without risking that your module won't on some platform because of the dependency. Where a clash exists between wanting more functionality and maintaining platform safety, this module will err on the side of platform safety. FUNCTIONS script_compiles script_compiles( $script, $test_name ); The "script_compiles" test calls the script with "perl -c script.pl", and checks that it returns without error. The path it should be passed is a relative Unix-format script name. This will be localised when running perl -c and if the test fails the local name used will be shown in the diagnostic output. Note also that the test will be run with the same perl interpreter that is running the test script (and not with the default system perl). This will also be shown in the diagnostic output on failure. This function was added in version 1.05. script_runs script_runs( $script, $test_name ); script_runs( \@script_and_arguments, $test_name ); script_runs( $script, \%options, $test_name ); script_runs( \@script_and_arguments, \%options, $test_name ); The "script_runs" test executes the script with "perl script.pl" and checks that it returns success. The path it should be passed is a relative unix-format script name. This will be localised when running perl -c and if the test fails the local name used will be shown in the diagnostic output. The test will be run with the same perl interpreter that is running the test script (and not with the default system perl). This will also be shown in the diagnostic output on failure. This function was added in version 1.05. You may pass in options as a hash as the second argument (as of version 1.09). exit The expected exit value. The default is to use whatever indicates success on your platform (usually 0). interpreter_options Array reference of Perl options to be passed to the interpreter. Things like -w or -x can be passed this way. This may be either a single string or an array reference. This option was added in version 1.25. signal The expected signal. The default is 0. Use with care! This may not be portable, and is known not to work on Windows. stdin The input to be passed into the script via stdin. The value may be one of simple scalar Is considered to be a filename. scalar reference In which case the input will be drawn from the data contained in the referenced scalar. The behavior for any other types is undefined (the current implementation uses Capture::Tiny). Any already opened stdin will be closed. stdout Where to send the standard output to. If you use this option, then the the behavior of the script_stdout_ functions below are undefined. The value may be one of simple scalar Is considered to be a filename. scalar reference In which case the standard output will be places into the referenced scalar The behavior for any other types is undefined (the current implementation uses Capture::Tiny). stderr Same as stdout above, except for stderr. script_stdout_is script_stdout_is $expected_stdout, $test_name; Tests if the output to stdout from the previous "script_runs" matches the expected value exactly. This function was added in version 1.09. script_stdout_isnt script_stdout_is $expected_stdout, $test_name; Tests if the output to stdout from the previous "script_runs" does NOT match the expected value exactly. This function was added in version 1.09. script_stdout_like script_stdout_like $regex, $test_name; Tests if the output to stdout from the previous "script_runs" matches the regular expression. This function was added in version 1.09. script_stdout_unlike script_stdout_unlike $regex, $test_name; Tests if the output to stdout from the previous "script_runs" does NOT match the regular expression. This function was added in version 1.09. script_stderr_is script_stderr_is $expected_stderr, $test_name; Tests if the output to stderr from the previous "script_runs" matches the expected value exactly. This function was added in version 1.09. script_stderr_isnt script_stderr_is $expected_stderr, $test_name; Tests if the output to stderr from the previous "script_runs" does NOT match the expected value exactly. This function was added in version 1.09. script_stderr_like script_stderr_like $regex, $test_name; Tests if the output to stderr from the previous "script_runs" matches the regular expression. This function was added in version 1.09. script_stderr_unlike script_stderr_unlike $regex, $test_name; Tests if the output to stderr from the previous "script_runs" does NOT match the regular expression. This function was added in version 1.09. program_runs program_runs( $program, $test_name ); program_runs( \@program_and_arguments, $test_name ); program_runs( $program, \%options, $test_name ); program_runs( \@program_and_arguments, \%options, $test_name ); The "program_runs" test executes the given program and checks that it returns success. This function works like "script_runs" except: * The path $program or @program_and_arguments is passed as-is to system() . This means program_runs can test any program, not just Perl scripts. * The %options do not support the interpreter_options key. See File::Spec or Path::Class for routines useful in building pathnames in a cross-platform way. This function was added in version 1.26. program_stdout_is program_stdout_is $expected_stdout, $test_name; Tests if the output to stdout from the previous "program_runs" matches the expected value exactly. program_stdout_isnt program_stdout_is $expected_stdout, $test_name; Tests if the output to stdout from the previous "program_runs" does NOT match the expected value exactly. program_stdout_like program_stdout_like $regex, $test_name; Tests if the output to stdout from the previous "program_runs" matches the regular expression. program_stdout_unlike program_stdout_unlike $regex, $test_name; Tests if the output to stdout from the previous "program_runs" does NOT match the regular expression. program_stderr_is program_stderr_is $expected_stderr, $test_name; Tests if the output to stderr from the previous "program_runs" matches the expected value exactly. program_stderr_isnt program_stderr_is $expected_stderr, $test_name; Tests if the output to stderr from the previous "program_runs" does NOT match the expected value exactly. program_stderr_like program_stderr_like $regex, $test_name; Tests if the output to stderr from the previous "program_runs" matches the regular expression. program_stderr_unlike program_stderr_unlike $regex, $test_name; Tests if the output to stderr from the previous "program_runs" does NOT match the regular expression. CAVEATS This module is fully supported back to Perl 5.8.1. The STDIN handle will be closed when using script_runs with the stdin option. An older version used IPC::Run3, which attempted to save STDIN, but apparently this cannot be done consistently or portably. We now use Capture::Tiny instead and explicitly do not support saving STDIN handles.
