Junit使用正确的资源

[英]Junit to use correct resources

原文 2015-04-20 06:38:44 4 1 java/ junit4

When writing unit tests for the application, usually I create copy of some configurations that are in original main/resources and modify them for test purpose, but i leave the names the same. 在为应用程序编写单元测试时，通常我会创建原始main/resources的某些配置的副本，并出于测试目的对其进行修改，但我将名称保持不变。 However Junit sometimes takes the one in src and sometimes the one in the test/resources . 但是Junit有时在src中使用一个，有时在test/resources 。

How do we manage which one it picks up without renaming files? 我们如何管理不重命名文件的文件？

For example i have some "config.json" which is in both test and main's resources, how does junit choose which one to pick when running a test... 例如，我在测试和main的资源中都有一些“ config.json”，junit在运行测试时如何选择要选择的那个...

Ok, just a quick answer: 好吧，一个简单的答案：

You cannot exclude resources from src/main/resources . 您不能从src/main/resources排除src/main/resources 。 They are always inside your class path and thus they are part of your program/library. 它们始终在您的类路径中，因此它们是您的程序/库的一部分。

But you shouldn't have to do so. 但是您不必这样做。

Log4j2 for example allows to have a differently named configuration file in the class path (while running the tests). 例如，Log4j2允许在类路径中（运行测试时）使用其他名称的配置文件。 Just name it log4j2-test.xml and it will be loaded prior to a non-test file. 只需将其命名为log4j2-test.xml ，它将在非测试文件之前加载。

Spring behaves the same when annotating the test classes with @ContextConfiguration . 当使用@ContextConfiguration注释测试类时，Spring的行为相同。
