NAME TAP::SimpleOutput - Simple closure-driven TAP generator VERSION This document describes version 0.001 of TAP::SimpleOutput - released October 02, 2012 as part of TAP-SimpleOutput. SYNOPSIS use TAP::SimpleOutput 'counter'; my ($_ok, $_nok, $_skip, $_plan) = counters(); say $_ok->('TestClass has a metaclass'); say $_ok->('TestClass is a Moose class'); say $_ok->('TestClass has an attribute named bar'); say $_ok->('TestClass has an attribute named baz'); do { my ($_ok, $_nok, $_skip, $_plan) = counters(1); say $_ok->(q{TestClass's attribute baz does TestRole::Two}); say $_ok->(q{TestClass's attribute baz has a reader}); say $_ok->(q{TestClass's attribute baz option reader correct}); say $_plan->(); }; say $_ok->(q{[subtest] checking TestClass's attribute baz}); say $_ok->('TestClass has an attribute named foo'); # STDOUT looks like: ok 1 - TestClass has a metaclass ok 2 - TestClass is a Moose class ok 3 - TestClass has an attribute named bar ok 4 - TestClass has an attribute named baz ok 1 - TestClass's attribute baz does TestRole::Two ok 2 - TestClass's attribute baz has a reader ok 3 - TestClass's attribute baz option reader correct 1..3 ok 5 - [subtest] checking TestClass's attribute baz ok 6 - TestClass has an attribute named foo DESCRIPTION We provide one function, "counters()", that returns a number of simple closures designed to help output TAP easily and correctly, with a minimum of fuss. FUNCTIONS counters($level) This function returns four closures that each generate a different type of TAP output. It takes an optional $level that determines the indentation level (e.g. for subtests). These coderefs are all closed over the same counter variable that keeps track of how many test have been run so far; this allows them to always output the correct test number. my ($_ok, $_nok, $_skip, $_plan) = counters(); $_ok->('whee') returns "ok 1 - whee" $_nok->('boo') returns "not ok 2 - boo" $_skip->('baz') returns "ok 3 # skip baz" $_plan->() returns "1..3" Note that calling the $_plan coderef only returns an intelligible response when called after all the output has been generated; this is analogous to using Test::More without a declared plan and "done_testing()" at the end. If you need or want to specify the plan prior to running tests, you'll need to do that manually. subtests When "counter()" is passed an integer, the generated closures all indent themselves appropriately to indicate to the test harness / TAP parser that a subtest is being run. (Namely, each statement returned is prefaced with "$level * 4" spaces.) It's recommended that you use distinct lexical scopes for subtests to allow the usage of the same variable names (why make things difficult?) without clobbering any existing ones and to ensure that the subtest closures are not inadvertently used at an upper level. my ($_ok, $_nok) = counters(); $_ok->('yay!'); $_nok->('boo :('); do { my ($_ok, $_nok, $_skip, $_plan) = counters(1); $_ok->('thing 1 good'); $_ok->('thing 2 good'); $_ok->('thing 3 good'); $_skip->('over there'); $_plan->(); }; $_ok->('subtest passed'); # returns ok 1 - yay! not ok 2 - boo :( ok 1 - thing 1 good ok 2 - thing 2 good ok 3 - thing 3 good ok 4 # skip over there 1..4 ok 3 - subtest passed USAGE WITH Test::Builder::Tester This package was created from code I was using to make it easier to test my test packages with Test::Builder::Tester: test_out $_ok->('TestClass has a metaclass'); test_out $_ok->('TestClass is a Moose class'); test_out $_ok->('TestClass has an attribute named bar'); test_out $_ok->('TestClass has an attribute named baz'); Once I realized I was using the exact same code (perhaps at different points in time) in multiple packages, the decision to break it out became pretty easy to make. SUBTESTS Subtest formatting can be done by passing a an integer "level" parameter to "counter()"; see the function's documentation for details.
