java - 为什么运行 mvn clean install 命令（在 Spring Boot 项目上）如果我注释掉这些方法以跳过测试，我也会获得单元测试失败？

问题描述

几年来我没有使用 Spring\Spring Boot，我正在使用这项技术开始一个项目，所以我有一些疑问。

我正在处理一个从 GIT 检索的简单项目，并开始着手实现我的功能。它工作正常，但我有以下疑问。

从命令行（进入我的项目的根目录）我使用以下命令编译它：

mvn clean install

为了删除我的应用程序的先前版本，然后再次编译、测试和打包我的应用程序。

然后我通过这个命令启动我的应用程序：

mvn spring-boot:run

并且应用程序正确启动：

它开始没有问题。当我执行mvn clean install命令时，我怀疑是在前一个阶段。它还执行项目内部定义的单元测试，但所有测试都失败了。这里有奇怪的行为。

我得到这样的异常：

在 Maven 安装阶段结束时，我有以下总结，说明所有测试都失败了：

Tests run: 4, Failures: 0, Errors: 2, Skipped: 0

奇怪的是，我在 JUnit 类中注释掉了所有的测试方法。例如前面的错误与这个测试类有关：

package com.springboot.excelapi.integration;

import java.io.IOException;
import java.util.List;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.ActiveProfiles;
import org.springframework.test.context.junit4.SpringRunner;
import org.springframework.test.context.web.WebAppConfiguration;

import com.springboot.excelapi.Application;

@RunWith(SpringRunner.class)
@SpringBootTest(classes = { Application.class })
@WebAppConfiguration
@ActiveProfiles(profiles = { "no-liquibase" })
public class ExcelResourceUnitTest {

    /*
    @Test
    public void processCompVibrAndTempoExcelTabTest()
    {
        final ExcelService excelService = new ExcelService();

        try {
            excelService.processCompVibrAndTempExcelTab();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
    */


}

正如你所看到的，这个类包含一个被注释掉的测试方法。

那么为什么当我执行mvn clean install命令时，它似乎正在尝试通过注释掉它来执行目前被禁用的测试方法？
