Junit单元测试

测试分类 黑盒测试：不需要写代码，给输入值，看输出值是否与期望值相同。 白盒测试：需要写代码，关注程序具体的执行流程。 Junit使用白盒测试 步骤： 定义一个测试类（测试用例） 建议： * 测试类名：被测试的类名+Test ：CalculatorTest * 包名：xxx.xxx.xx.Test cn.edu.test 定义测试方法：可以独立运行 建议： * 方法名：test测试的方法名 testAdd（） * 返回值：void * 参数列表：空参 在方法上添加@Test 导入Junit依赖环境 判定结果： 红色：失败 绿色：成功 一般我们会使用断言操作来处理结果 Assert.assertEquals(期望的结果，运算的结果)； 补充： @Before: 修饰的方法在测试方法执行前被自动执行 @After： 修饰的方法会在测试方法执行后被自动执行。 来源： CSDN 作者： weixin_43649997 链接： https://blog.csdn.net/weixin_43649997/article/details/103927716

How do I perform a Unit Test using threads? [duplicate]

由 痴心易碎 提交于 2020-01-10 18:43:46
问题 This question already has answers here : How should I unit test threaded code? (25 answers) Closed 2 years ago . Executive Summary: When assertion errors are thrown in the threads, the unit test doesn't die. This makes sense, since one thread shouldn't be allowed to crash another thread. The question is how do I either 1) make the whole test fail when the first of the helper threads crashes or 2) loop through and determine the state of each thread after they have all completed (see code below

How do you test code written against AWS API [closed]

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 8 months ago . I'm writing an application in Java that will upload a file up to AWS S3. The file will be given to the application in an argument, not hardcoded. I'd like to write tests to ensure that the file actually gets uploaded to S3. The test will be written before the code for TDD. (I

关于测试覆盖率

关于测试覆盖率 您还记得大多数开发人员踏上代码质量潮流之前的情况吗？在那些日子里，熟练地放置main() 方法被认为既敏捷又足以进行测试。从那时起，我们已经走了很长一段路。首先，我非常感谢自动化测试现已成为以质量为中心的代码开发的重要方面。这不是我要感谢的全部。Java开发人员拥有大量工具，可通过代码指标，静态分析等来衡量代码质量，我们甚至设法将重构归为一组便捷的模式！ 确保您的代码质量 所有这些新工具使确保代码质量比以往更加容易，但是您必须知道如何使用它们。在本系列文章中，我将重点介绍确保代码质量的有时有些不可思议的细节。除了使您熟悉可用于代码质量保证的各种工具和技术之外，我还将向您展示如何解决以下问题： 定义并有效衡量对代码质量影响最大的方面。 设定质量保证目标并相应地计划您的开发工作。 确定哪些代码质量工具和技术真正满足您的需求。 实施最佳实践（并淘汰不良实践），以便尽早确保代码质量，并且通常成为开发实践中不费力且有效的方面。 我将从这个月开始， 看看 Java开发人员的质量保证工具包中最流行，最简单的功能之一：测试覆盖率测量。 当心被忽悠 使用测试覆盖率工具没有任何欺骗的可能。它们是单元测试范例的一个很好的补充。重要的你在获取到这些信息的时候，如何综合考量并加以推广，这是一些开发团队犯下的第一个错误。 高覆盖率仅意味着要执行大量代码。高覆盖率并不意味着代码可以很好地执行

Mockito bypass static method for testing

由 你。 提交于 2020-01-10 02:34:24
问题 I need to test handleIn() method using Mockito. However the code need to call this legacy code Util.getContextPDO which is a static method. Note that in testing environment this Util.getContextPDO is always returns Exception, and I intend to bypass this Util.getContextPDO() by always return a dummy IPDO. public class MyClass { public IPDO getIPDO() { return Util.getContextPDO(); // note that Util.getContextPDO() is a static, not mockable. } public String handleIn(Object input) throws

Access to h2 web console while running junit test in a Spring application

问题 I'm building a Spring application and I need to inspect my H2 in-memory database while I'm running my JUnit tests from a web browser. In my Spring configuration I have a bean which is responsible of creating my database schema and populating it with some data which will be used within my JUnit tests. I've also added a bean in my test context which creates a web server where I eventually will look for my data. <bean id="org.h2.tools.Server-WebServer" class="org.h2.tools.Server" factory-method=
