How do I parse a Typoscript file? - typo3

Question

I am writing a unit test and want to check if the data in a certain typoscript file satisfies my requirements. How do I convert the text file to an array? The Typo3-Framework is available.
My google research points to using the class \TYPO3\CMS\Core\TypoScript\Parser\TypoScriptParser but I don't find usage examples ...
(Using Typo3 7.6)

Answer 1

This is working (but possibly there are nicer ways to do this):
<?php
use TYPO3\CMS\Core\TypoScript\Parser\TypoScriptParser;
class TyposcriptTest extends \TYPO3\CMS\Core\Tests\UnitTestCase {
public function setUp() {
parent::setUp();
$this->objectManager = \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance('TYPO3\\CMS\\Extbase\\Object\\ObjectManager');
}
protected function loadTSFile($filename) {
$content = file_get_contents($filename);
$parser = $this->objectManager->get(TypoScriptParser::class);
$parser->parse($content);
return $parser->setup;
}
public function testTS() {
$array = $this->loadTSFile('...');
$this->assertTrue(isset($array['tx_extension.']['flexForm.']['andsoon.']]), 'Assertion failed. TS content: ' . var_export($array, true));
}
}

Here is the working example for TYPO3 v - 10.4.x
$tsString = 'colors {
backgroundColor = red
fontColor = blue
}
[ip("123.45.*")]
headerImage = fileadmin/img1.jpg
[ELSE]
headerImage = fileadmin/img2.jpg
[GLOBAL]
// Wonder if this works... :-)
wakeMeUp = 7:00';
$TSparserObject = \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance(
\TYPO3\CMS\Core\TypoScript\Parser\TypoScriptParser::class
);
$TSparserObject->parse($tsString);
echo '<pre>';
print_r($TSparserObject->setup);
echo '</pre>';
