SystemOutRule和调试堆栈的问题

Question

嘿，我在JUnit(4.12)中的SystemOutRule日志和测试有问题。

我有一个简单的测试类：

package com.example.demo;

import config.FootballerConfig;

import org.junit.Assert;
import org.junit.Rule;
import org.junit.Test;
import org.junit.contrib.java.lang.system.SystemOutRule;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;


import static org.junit.Assert.*;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = FootballerConfig.class)
public class FootballerConfigTest {

    @Rule
    public final SystemOutRule log = new SystemOutRule().enableLog();

    @Autowired
    private FootballerStats footballerStats;

    @Autowired
    private Footballer footballer;

    @Test
    public void footballerShouldNotBeNull() {
        assertNotNull(footballer);
    }

    @Test
    public void getPosition() {
        footballerStats.getPosition();
        Assert.assertEquals("I'm playing as defender", log.getLogWithNormalizedLineSeparator().trim());
    }
}

null

Answer 1

好的。我做到了。在getPosition（）方法中使用log.clear（）就足够了。

@Test
public void getPosition() {
    log.clearLog();
    footballerStats.getPosition();
    Assert.assertEquals("I'm playing as defender\n", log.getLogWithNormalizedLineSeparator());
}
