jUnitテストのエラーを取り除くことはできませんか？

Question

package lib; 

import static org.junit.Assert.*;

} 

このトップはオブジェクトであり、クラスはそれを使用していませんこれは私がこれまで持っていたものです。

package main; 

public class Module { 

    //Fields 
    private String code; 
    private String name; 
    private int examWeight; 
    private int cwkWeight; 


    //Constructors 
    public Module() { 
     this("CTEC0000", "", 50); 
    } 

    public Module(String code, String name) { 
     this(code, name, 50); 
    } 

    public Module(String code, String name, int examWeight) { 
     this.code = code; 
     this.name = name; 
     this.examWeight = examWeight; 
     this.cwkWeight = 100 - examWeight; 
    } 


    //Methods 
    public String getCode() { 
     return code; 
    } 

    public void setCode(String code) { 
     this.code = code; 
    } 

    public String getName() { 
     return name; 
    } 

    public void setName(String name) { 
     this.name = name; 
    } 

    public int getExamWeight() { 
     return examWeight; 
    } 

    public void setExamWeight(int examWeight) { 
     this.examWeight = examWeight; 
     this.cwkWeight = 100 - examWeight; 
    } 

    public int getCwkWeight() { 
     return cwkWeight; 
    } 

    public void setCwkWeight(int cwkWeight) { 
     this.cwkWeight = cwkWeight; 
     this.examWeight = 100 - cwkWeight; 
    } 

    @Override 
    public String toString() { 
     return "Module:[code=" + code + ", name=" + name + 
       ", examWeight=" + examWeight + ", cwkWeight=" + cwkWeight + "]"; 
    } 

} 

トップコードにエラーが表示され続けると、モジュールをタイプヘルプに解決できません。

Answer 1

：

package lib; 

import static org.junit.Assert.*; 

import org.junit.Test; 

public class ModuleTest { 

main.Moduleクラスがインポートされません。
したがって、完全修飾名なしでModule m = new Module(); と入力すると、コンパイラで認識されません。

main.Module m = new main.Module();はコンパイルには適していますが、この場合は可読性が低下します。だから、ModuleTestでModuleクラスをインポート
がより適しているようだ：

とにかく

package lib; 

import static org.junit.Assert.*; 

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

public class ModuleTest { 

、IDEを使用している場合、あなたは自動的に不足している輸入を解決するためのオプションを持っている必要があります。だから、それを使ってください。
さらに、テストされたクラスと同じパッケージをテストクラスに使用することをお勧めします。
副作用として、クラスをModuleTestクラスにインポートする必要はありません。
理想的には、ModuleとModuleTestは同じパッケージにありますが、同じフォルダには存在しません（テスト用とアプリケーション用の両方）。

Answer 2

ModuleTest.javaファイルに

import main.Module; 

を追加します。ここで
