Ich hab mir simpleTest heruntergeladen, die Dateien erstellt und die DictionaryTest geöffnet und es kommt die Fehlermeldung:

Code

Warning: require_once(D:\xampp\htdocs\dictionary\simpletest/arguments.php) [function.require-once]: failed to open stream: No such file or directory in D:\xampp\htdocs\dictionary\simpletest\reporter.php on line 13




Fatal error: require_once() [function.require]: Failed opening required 'D:\xampp\htdocs\dictionary\simpletest/arguments.php' (include_path='.;\xampp\php\PEAR') in D:\xampp\htdocs\dictionary\simpletest\reporter.php on line 13

Und wirklich, die Datei arguments.php existiert im simpletest-Ordner nicht, dabei wird von einer anderen simpletest-Datei versucht sie zu laden. Es liegt also nicht an deinem Code.

Kannst du uns vielleicht mal deine benutzbraen Dateien schicken, die wir dafür brauchen und vielleicht auch noch ein kleines Beispielscript, ich habe nämlich keine Lust mich durch den gesamten Code durchzuarbeite, um etwas lauffähiges auf die Beine zu stellen.

Was mir aber so schon aufgefallen ist: Du benutzt in der ersten Datei noch teilweise public und protected, danach aber gar nicht mehr. Ist schöner, wenn diese keywörter vor jeder Methode / Eigenschaft stehen.

Hallo Sören,

danke für Dein Feedback. Ich vermute Du hast die neueste Version. Ich habe noch die ältere und in der Datei reporter.php ist die Zeile die arguments.php includet auskommentiert. //require_once(dirname(__FILE__) . '/arguments.php');
Ich werde mal testen ob ich den Test mit der neusten Version zum laufen bringe, vielleicht kannst Du mal probieren ob es reicht die oben erwähnte Zeile rauszunehmen.

Hast recht, ich werde es machen.

Ja, ich hab die neueste Version, das aukommentieren hat aber gereicht.

Kritik hab ich keine, läuft alles so, wie es soll.

Vielleicht kannst du noch ne Möglichkeit einbauen, mehrere Elemente in einem Array hinzuzufügen, dann muss man nicht dauernd das gleiche tippen.
