ruby on rails - How to write Minitest spec for ApplicationHelper? -


i know how write following style of test minitest...

 require "minitest_helper" class applicationhelpertest < actionview::testcase def test_nav_element_for_current_page self.stub(:current_page?, true) nav_element('home', '#').must_equal( '<li class="active"><a href="#">home</li>') end end def test_nav_element_for_non_current_page self.stub(:current_page?, false) nav_element('home', '#').must_equal( '<li><a href="#">home</li>') end end end

...but want write in spec format. here have tried, not work:

 require "minitest_helper" describe applicationhelper "nav_element current page" self.stub(:current_page?, true) nav_element('home', '#').must_equal( '<li class="active"><a href="#">home</li>') end end "nav_element non-current page" self.stub(:current_page?, false) nav_element('home', '#').must_equal( '<li><a href="#">home</li>') end end end

how tell minitest applicationhelper should automatically include actionview::testcase? i've tried several things, no luck yet.

just background, application_helper.rb contains:

 module applicationhelper def nav_element(text, path) options = {} options[:class] = 'active' if current_page?(path) link_tag = content_tag(:a, text, href: path) content_tag(:li, link_tag, options) end end

i using these bundled gems:

 * rails (3.2.6) * minitest (3.2.0) * minitest-rails (0.1.0.alpha.20120525143907 7733031)

(please note head version of minitest_rails (https://github.com/blowmage/minitest-rails).)

minitest::rails didn't implement actionview::testcase until morning. bringing attention! :)

this fix in 0.1 release. now, change gemfile , link minitest-rails against git repo:

gem "minitest-rails", :git => "git://github.com/blowmage/minitest-rails.git"

edit: works now. code should following:

require "minitest_helper" describe applicationhelper "nav_element current page" # stub ruby! def self.current_page?(path); true; end nav_element('home', '#').must_equal( '<li class="active"><a href="#">home</a></li>') end "nav_element non-current page" def self.current_page?(path); false; end nav_element('home', '#').must_equal( '<li><a href="#">home</a></li>') end end

that should need do. if have other problems please start discussion on mailing list. https://groups.google.com/group/minitest-rails

php - Get uncommon values from two or more arrays -

is there function in php give array of uncommon values 2 or more arrays? for example: $array1 = array( "green", "red", "blue"); $array2 = array( "green", "yellow", "red"); .... $result = function_needed($array1, $array2,...); print_r($result); should give output: array("blue", "yellow", ...); use array_diff , array_merge : $result = array_merge(array_diff($array1, $array2), array_diff($array2, $array1)); here's demo. for multiple arrays, combine callback , array_reduce : function unique(&$a, $b) { return $a ? array_merge(array_diff($a, $b), array_diff($b, $a)) : $b; } $arrays = array( array('green', 'red', 'blue'), array('green', 'yellow', 'red') ); $result = array_reduce($arrays, 'unique'); and here's demo of that.

Adding duplicate array rows in Php -

i create function in php adds rows of array shared column value. so input. $test = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); and output. $testduplicatefree = array( array("c", 7, 9), array("test", 5, 6) ) ); i'm thinking function combine_duplicates($array,$col){ ... ... return $duplicatefreearray; } where $col duplicate free array. so, in case, combine_duplicates($test,0); would me desired output. this. <?php function combine_duplicates($array,$col) { $index = array(); foreach ($array $row) { $key = $row[$col]; if (!isset($index[$key])) { $index[$key] = $row; } else { ($i = 0; $i < count($row); ++$i) { if ($i != $col) { $index[$key][$i] += $row[$i]; } } } } return array_values($index); } $array = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); print_r(combine_duplicates($array, 0)); try here: http://codepad.org/mdhesqhi
