Ich kann die Fehler aus dem jUnit-Test nicht entfernen?

Question

package lib;

     assertTrue("The toString method should be in the standard convention format", 
       toStr.startsWith("Module:[") &&

       toStr.contains("=" + m.getName() + ", ") && 
       toStr.contains("=" + m.getExamWeight() + ", ") && 
       toStr.endsWith("=" + m.getCwkWeight() + "]")); 
    } 

} 

Dieses Top ist das Objekt und die Klasse arbeitet nicht damit, das ist was ich bisher habe.

Ich bekomme immer Fehler in der Top-Code Spruch Modul kann nicht zu einem Typ Hilfe bitte gelöst werden.

Answer 1

hier:

package lib; 

import static org.junit.Assert.*; 

import org.junit.Test; 

public class ModuleTest { 

main.Module Klasse wird nicht importiert.
So eingeben Module m = new Module(); ohne den voll qualifizierten Namen wird nicht vom Compiler erkannt.

main.Module m = new main.Module(); ist korrekt für die Kompilation, aber es reduziert in diesem Fall die Lesbarkeit.
Module Klasse in ModuleTest So importieren scheint besser geeignet:

package lib; 

import static org.junit.Assert.*; 

import org.junit.Test; 
import main.Module; 

public class ModuleTest { 

Wie auch immer, wenn Sie eine IDE verwenden, sollten Sie eine Möglichkeit haben, automatisch die fehlende Importe zu lösen. Also, benutze es.
Außerdem ist es eine gute Übung, das gleiche Paket für die Testklasse als für die getestete Klasse zu verwenden.
Als Nebeneffekt müssen Sie die Klasse Module nicht in die Klasse ModuleTest importieren.
Idealerweise sollten Module und ModuleTest im selben Paket sein, aber nicht im selben Ordner: einer zum Testen und der andere für die Anwendung.

Answer 2

hinzufügen

import main.Module; 

zum ModuleTest.java Datei.
