Proposal for xSpec BDD Framework for PHP Beyond PHPUnit and PHPSpec @yuya_takeyama

Recent Activities• Making DSL with [] (#phpcon2011 LT) http://blog.yuyat.jp/archives/1355• PHPUnit でよりよくテストを書くために http://blog.yuyat.jp/archives/1386• phpenv で複数の PHP 環境を管理する http://blog.yuyat.jp/archives/1446• Building Development Environment with php-build and phpenv http://blog.yuyat.jp/archives/1461• 例えば, Singleton を避ける (New! #TddAdventJp) http://blog.yuyat.jp/archives/1500

xSpec?

xUnit?

xUnit (Unit Testing Frameworks)• SUnit (Smalltalk)• JUnit (Java)• Test::Unit (Ruby)• PHPUnit (PHP)

xSpec? reprise

xSpec (Testing Frameworks for BDD) • RSpec (Ruby) • Jasmine (JavaScript) • specs (Scala) • PHPSpec (PHP)

BDD (Behaviour Driven Development)• Not test, specify!• It should ...• Expressive• Test as Documentation

RSpec exampledescribe Bowling do describe #score do context all gutter game do before do @bowling = Bowling.new 20.times { @bowling.hit(0) } end it should equal 0 do @bowling.score.should eq(0) end end endend

I ❤PHPUnit

But...

Issue of PHPUnit/PHPSpec•No nested context•Speciﬁcation with camelCase or lower_case_with_underscore

Issue of PHPUnit/PHPSpec• I want more No nested context• exp ressiv Speciﬁcation with eness! camelCase or lower_case_with_underscore

Proposal #1 Use functionin namespace, Not method in class

Speciphy examplenamespace SpeciphyDSL;return describe(Bowling, array( describe(->score, array( context(all gutter game, array( subject => function () { $bowling = new Bowling; for ($i = 1; $i <= 20; $i++) { $bowling->hit(0); } return $bowling; }, it(should equal 0, function ($bowling) { $bowling->score->should->equal(0); }), )), )), SpeciphyDSLdescribe));

Speciphy examplenamespace SpeciphyDSL;return describe(Bowling, array( describe(->score, array( context(all gutter game, array( subject => function () { $bowling = new Bowling; for ($i = 1; $i <= 20; $i++) { $bowling->hit(0); } return $bowling; }, it(should equal 0, function ($bowling) { $bowling->score->should->equal(0); }), )), )), SpeciphyDSLcontext));

Speciphy examplenamespace SpeciphyDSL;return describe(Bowling, array( describe(->score, array( context(all gutter game, array( subject => function () { $bowling = new Bowling; for ($i = 1; $i <= 20; $i++) { $bowling->hit(0); } return $bowling; }, it(should equal 0, function ($bowling) { $bowling->score->should->equal(0); }), )), )), SpeciphyDSLit));

Proposal #2 Use array to buildnested context.

Speciphy examplenamespace SpeciphyDSL;return describe(Bowling, array( describe(->score, array( context(all gutter game, array( subject => function () { $bowling = new Bowling; for ($i = 1; $i <= 20; $i++) { $bowling->hit(0); } return $bowling; }, it(should equal 0, function ($bowling) { $bowling->score->should->equal(0); }), )), )), Nested context));

Array, A StrangeData Structure

[ "foo", "bar", "hoge" => "piyo"]

array(3) { [0]=> string(3) "foo" [1]=> string(3) "bar" ["hoge"]=> string(4) "piyo"}

Like keywordarguments

Model Deﬁnitionpublic $id = [ int, primary => true, serial => true];public $name = [ string, required => true, unique => true];public $birthday = [date];

Paml https://github.com/yuya-takeyama/php-HTML_Paml["div", ["ul", ["li", "Foo"] ["li", "Bar"] ["li", "Baz"]]]

HTML Generation<div> <ul> <li>Foo</li> <li>Bar</li> <li>Baz</li> </ul></div>

LisPHP https://github.com/yuya-takeyama/LisPHP[begin, [define, fib, [lambda, [x], [if, [<, :x, 2], :x, [+, [fib, [-, :x, 2]], [fib, [-, :x, 1]]]]]], [print, fib(10) = ], [println, [fib, 10]]] => fib(10) = 55

Speciphy examplenamespace SpeciphyDSL;return describe(Bowling, array( describe(->score, array( context(all gutter game, array( subject => function () { $bowling = new Bowling; for ($i = 1; $i <= 20; $i++) { $bowling->hit(0); } return $bowling; }, it(should equal 0, function ($bowling) { $bowling->score->should->equal(0); }), )), )), $arr[ subject ]));

Speciphy examplenamespace SpeciphyDSL;return describe(Bowling, array( describe(->score, array( context(all gutter game, array( subject => function () { $bowling = new Bowling; for ($i = 1; $i <= 20; $i++) { $bowling->hit(0); } return $bowling; }, it(should equal 0, function ($bowling) { $bowling->score->should->equal(0); }), )), )), $arr[0]));

Conclusion•Use function in namespace, Not method in class•Use array to build nested structure•Enjoy BDD with xSpec
