我在哪里配置JUnit测试类中的log4j？ [英] Where do I configure log4j in a JUnit test class?

问题描述

看看我写的最后一个JUnit测试用例，我在类构造函数中调用了log4j的BasicConfigurator.configure（）方法。这对于从Eclipse的作为JUnit测试用例运行命令中运行该单个类来说效果很好。但我意识到这是不正确的：我很确定我们的主要测试套件从一个进程运行所有这些类，因此log4j配置应该在某个地方更高。

Looking at the last JUnit test case I wrote, I called log4j's BasicConfigurator.configure() method inside the class constructor. That worked fine for running just that single class from Eclipse's "run as JUnit test case" command. But I realize it's incorrect: I'm pretty sure our main test suite runs all of these classes from one process, and therefore log4j configuration should be happening higher up somewhere.

但我仍然需要自己运行一个测试用例，在这种情况下我想配置log4j。我应该在哪里放置配置调用，以便在测试用例独立运行时运行，而不是在测试用例作为更大套件的一部分运行时运行？

But I still need to run a test case by itself some times, in which case I want log4j configured. Where should I put the configuration call so that it gets run when the test case runs standalone, but not when the test case is run as part of a larger suite?

推荐答案

LogManager 类确定在静态块，在加载类时运行。最终用户有三种选择：

The LogManager class determines which log4j config to use in a static block which runs when the class is loaded. There are three options intended for end-users:

1. 如果指定 log4j.defaultInitOverride 为false，它根本不会配置log4j。



2. 自己手动指定配置文件的路径并覆盖类路径搜索。您可以使用以下参数直接指定配置文件的位置 java ：

1. If you specify log4j.defaultInitOverride to false, it will not configure log4j at all.

2. Specify the path to the configuration file manually yourself and override the classpath search. You can specify the location of the configuration file directly by using the following argument to java:

-Dlog4j.configuration =<属性文件的路径>

在您的测试运行器配置中。

in your test runner configuration.

允许log4j在测试期间扫描log4j配置文件的类路径。 （默认）

Allow log4j to scan the classpath for a log4j config file during your test. (the default)
