started to add some unit tests to config manager

Parsing the config file should be completely tested before we can rely
on it and safely extend it. This just adds the first very basic tests.

lib/plugins/config/_test/configuration.test.php

+<?php
+
+class plugin_config_configuration_test extends DokuWikiTest {
+
+    private $config = '';
+    private $meta = '';
+
+    function __construct() {
+        $this->config = dirname(__FILE__).'/data/config.php';
+        $this->meta   = dirname(__FILE__).'/data/metadata.php';
+        require_once(dirname(__FILE__).'/../settings/config.class.php');
+    }
+
+    function test_readconfig() {
+        $confmgr = new configuration($this->meta);
+
+        $conf = $confmgr->_read_config($this->config);
+
+        //print_r($conf);
+
+        $this->assertEquals('42', $conf['int1']);
+        $this->assertEquals('6*7', $conf['int2']);
+
+        $this->assertEquals('Hello World', $conf['str1']);
+        $this->assertEquals('G\'day World', $conf['str2']);
+        $this->assertEquals('Hello World', $conf['str3']);
+        $this->assertEquals("Hello 'World'", $conf['str4']);
+        $this->assertEquals('Hello "World"', $conf['str5']);
+    }
+
+}
