java单侧执行顺序

## 场景 ##

一般跑单侧是不需要管顺序的,但是有时候写增删改查的时候,需要将新建的单侧先执行,然后在进行其他操作,最后删除,这时候,可以通过注解和测试的名称来调整单侧的执行顺序;

## 使用 ##

Junit测试可以通过注解@FixMethodOrder调整测试顺序:

## 参数 ##

也就是MethodSorters枚举的参数

*  MethodSorters.JVM：按照JVM得到的方法顺序（每次都不一样）
 *  MethodSorters.DEFAULT：默认的顺序，以不可预期的顺序执行(不管你的单侧顺序,每次都是一样的)
 *  MethodSorters.NAME\_ASCENDING：按照方法名字母顺序执行(每次一样)

/** * Sort the methods into a specified execution order. * Defines common {@link MethodSorter} implementations. * * @since 4.11 */
    public enum MethodSorters { 
        /** * Sorts the test methods by the method name, in lexicographic order, * with {@link Method#toString()} used as a tiebreaker */
        NAME_ASCENDING(MethodSorter.NAME_ASCENDING),
    
        /** * Leaves the test methods in the order returned by the JVM. * Note that the order from the JVM may vary from run to run */
        JVM(null),
    
        /** * Sorts the test methods in a deterministic, but not predictable, order */
        DEFAULT(MethodSorter.DEFAULT);
    
        private final Comparator<Method> comparator;
    
        private MethodSorters(Comparator<Method> comparator) { 
            this.comparator = comparator;
        }
    
        public Comparator<Method> getComparator() { 
            return comparator;
        }
    }

## 测试 ##

@FixMethodOrder(MethodSorters.JVM)
    public class MethodOrderTest { 
    
      @Test
      public void btest() { 
        System.out.print("3");
      }
    
      @Test
      public void atest2() { 
        System.out.print("1");
      }
    
      @Test
      public void atest1() { 
        System.out.print("2");
      }
    
      @Test
      public void ctest() { 
        System.out.print("4");
      }
    
    }
