我在我的 class 中使用这个记录器,如下所述。
private static final Logger log = Logger.getInstance(TimeZoneUtil.class);
如果在我的测试版本中我包含如下所述的 commons-apache-logger-dependency,那么我不会收到任何名为 java.lang.NoClassDefFoundError 的错误:org/apache/commons/logging/LogFactory
<fileset dir="./../thirdparty/commons-logging-1.1.1">
<include name="*.jar" />
</fileset>
但我不想在我的测试构建中使用这个包含的 jar,所以有任何其他方法可以模拟 getInstance() 方法,所以它不应该进入记录器 class 来创建日志或任何其他摆脱此错误的方法。
目前我正在使用下面提到的 Power Mockito,通过它我可以模拟 Logger class 但即使在模拟它之后我也会收到错误。
PowerMockito.mockStatic(Logger.class);
Logger logger = mock(Logger.class);
when(Logger.getInstance(TimeZoneUtil.class)).thenReturn(logger);
when(Logger.getInstance(any(String.class))).thenReturn(logger);
