Junit4

Question

私はこれを実行している、私がテストメソッドで複数の条件をテストできるようにするパラメータ化テストとして実行しようとしているJUnitテスト、下に持っているしかし

import org.junit.Test; 
import org.junit.runner.RunWith; 
import org.junit.runners.Parameterized; 

import java.util.Arrays; 
import java.util.List; 

import static org.junit.Assert.assertEquals;  
@RunWith(Parameterized.class) 
    public class ProductCategoryTest { 


     private boolean isAggregate; 
     private ProductCategory category; 

     public ProductCategoryTest(boolean isAggregate, ProductCategory category) { 
      this.isAggregate = isAggregate; 
      this.category = category; 
     } 

     @Parameterized.Parameters 
     public static List<Object[]> categoryList() { 
      return Arrays.asList(new Object[][]{ 
        {true, new ProductCategory("A", "Laundry", ProductCategory.Type.Aggregate)}, 
        {false, new ProductCategory("B", "Dryer", ProductCategory.Type.Individual)}, 
      }); 
     } 

     @Test 
     public void isAggregateProductCategory() throws Exception { 
      assertEquals(isAggregate, category.isAggregateProductCategory()); 
     } 

    } 

私が手例外：

java.lang.Exception: No tests found matching categoryList with any parameter from org.junit.runner.Request$1@123772c4

Answer 1

自分のコードを自分のPCで試しましたが、それは自分のPC上で正常に動作します。 あなたの環境で使用しているライブラリやJUnitランナーに問題があると思われます。

あなた自身のテストランナーを試してみてください。それを行う方法の例を次に示します：APIの `@ Parameters`アノテーションの中で、

import org.junit.Test; 
import org.junit.runner.JUnitCore; 
import org.junit.runner.RunWith; 
import org.junit.runner.notification.Failure; 
import org.junit.runners.Parameterized; 
import java.util.Arrays; 
import java.util.List; 
import org.junit.runner.Result; 
import static org.junit.Assert.assertEquals; 

class ProductCategory { 
    enum Type { 
     Aggregate, Individual 
    }; 

    public ProductCategory(String a, String b, Type t) { 

    } 
} 

@RunWith(Parameterized.class) 
    public class ProductCategoryTest { 


     private boolean isAggregate; 
     private ProductCategory category; 

     public ProductCategoryTest(boolean isAggregate, ProductCategory category) { 
      this.isAggregate = isAggregate; 
      this.category = category; 
     } 

     @Parameterized.Parameters 
     public static List<Object[]> categoryList() { 
      return Arrays.asList(new Object[][]{ 
        {true, new ProductCategory("A", "Laundry", ProductCategory.Type.Aggregate)}, 
        {false, new ProductCategory("B", "Dryer", ProductCategory.Type.Individual)}, 
      }); 
     } 

     @Test 
     public void isAggregateProductCategory() throws Exception { 
      //assertEquals(isAggregate, category.isAggregateProductCategory()); 
     } 


     public static void main(String[] args) { 
      Result result = JUnitCore.runClasses(ProductCategoryTest.class); 

      for (Failure failure : result.getFailures()) { 
       System.out.println(failure.toString()); 
      } 

      System.out.println(result.wasSuccessful()); 
     } 
    }
