我们正在使用Togglz来打开和关闭项目中的功能。以下TogglzFeature枚举正在实现org.togglz.core.Feature接口
public enum TogglzFeature implements Feature {
@EnabledByDefault
@Label("Current XSLT code")
FEATURE_XSLT,
@Label("NEW JAXB code")
FEATURE_JAXB;
public boolean isActive() {
FeatureManager manager = FeatureContext.getFeatureManager();
return manager.isActive(this);
}
}
然后，正在测试的方法之一(例如
mut_1(params))正在检查枚举，例如if(TogglzFeature.FEATURE_JAXB.isActive()) { dothings();}
请注意，togglz功能不在mut_1的参数中。 mut_1只是在运行时从上下文中选取它。
那么让mut_1()知道我希望
TogglzFeature.FEATURE_JAXB.isActive()返回true的最佳方法是什么？我尝试了Mockito / PowerMock
@RunWith(PowerMockRunner.class)
@PrepareForTest({TogglzFeature.class})
public class myTestClass {
//private members and set up
@Test
public void testTogglz(){
PowerMockito.mockStatic(TogglzFeature.class);
BDDMockito.given(TogglzFeature.FEATURE_JAXB.isActive()).willReturn(true);
//execution and verification
}
}
系统会将所有这些吐给我

最佳答案
您无需嘲笑任何东西。 Togglz随附了一个用于单元测试功能切换的特殊模块。在这里看看:
http://www.togglz.org/documentation/testing.html
例如，有一个JUnit规则，提供了一种切换功能的简单方法:
public class SomeJunitTest {
@Rule
public TogglzRule togglzRule = TogglzRule.allEnabled(MyFeatures.class);
@Test
public void testToggleFeature() {
// all features are active by default
assertTrue(MyFeatures.FEATURE_ONE.isActive());
// you can easily modify the feature state using the TogglzRule
togglzRule.disable(MyFeatures.FEATURE_ONE);
assertFalse(MyFeatures.FEATURE_ONE.isActive());
}
}
