从Eclipse的Junit测试中捕获时序数据 [英] Capturing timing data from Junit tests on Eclipse

问题描述

在Eclipse Galileo（3.5）上运行，我注意到我的测试显示了每次测试运行的时间。有没有办法捕获和这些信息？是否有API或存储在结果文件中？

推荐答案

我们可以使用Rule获取每个测试方法的持续时间：

We could use Rule to get time durations for each test method:

class TimeConsumeRule implements MethodRule {
    @Override
    public Statement apply(final Statement base, final FrameworkMethod method, Object target) {
        return new Statement() {
            @Override
            public void evaluate() throws Throwable {
                long start = System.currentTimeMillis();
                try {
                    base.evaluate();
                } finally {
                    System.out.println(method.getName()+ " used "+ (System.currentTimeMillis() - start)+" ms;");
                }
            }
        };
    }
}
public class TimeConsume {
    //Just declare customized Rule in your test case.
    @Rule
    public MethodRule rule = new TimeConsumeRule();

      @Test
      public void test1(){ 
       //...
      }

      @Test
      public void test2(){ 
       //...
      }
}
