[TYPO3-dev] TypoScript template for unit testing

[Elmar Hinz]

Hello,

for unit tests you need invariant test setups. This example shows a way
to set a defined TS template, that does not depend on a page in the
pagetree. It simply loads the TS from css_styled_content. 

It works with the unit test extension phpunit. An empty
$GLOBALS['TSFE']->tmpl has already been created by the parent class.


class tx_example_testcase extends tx_phpunit_testcase {

        protected function setup() {
                require_once(PATH_t3lib.'class.t3lib_tsparser.php');
                $dir = 'EXT:css_styled_content/static/';
                $dir = t3lib_div::getFileAbsFileName($dir);
                $constants = join('', file($dir . 'constants.txt'));
                $TSparserObject = t3lib_div::makeInstance('t3lib_tsparser');
                $TSparserObject->parse($constants);
                $constants = $TSparserObject->setup;
                $this->makeFlatConstantKeys($constants);
                $setup = join('', file($dir . 'setup.txt'));
                $setup = $this->substituteConstants($setup);
                $TSparserObject->parse($setup);
                $GLOBALS['TSFE']->tmpl->setup = $TSparserObject->setup;
        }

        protected function makeFlatConstantKeys($constantArray) {
                foreach($constantArray as $key => $value) {
                        $tempKey = $this->flatConstantKey;
                        $this->flatConstantKey.= $key;
                        if(is_array($value)) $this->makeflatConstantKeys($value);
                        else $this->flatConstants[$this->flatConstantKey] = $value;
                        $this->flatConstantKey = $tempKey;
                }
        }
        
        protected function substituteConstants($line) {
                return preg_replace_callback('/\{\$(.[^}]+)\}/m',
array($this, 'substituteConstantsCallBack'), $line);
        }

        protected function substituteConstantsCallBack($matches) {
                return isset($this->flatConstants[$matches[1]]) ?
$this->flatConstants[$matches[1]] : $matches[0];
        }
