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");
  }

}
