如何在没有Powermock的情况下模拟静态方法 [英] How to mock static method without powermock
问题描述
在JUnit中进行测试时,有什么方法可以模拟静态util方法?
我知道Powermock可以模拟静态调用,但是我不想使用Powermock.
还有其他选择吗?
(我假设您可以使用Mockito)我没想到什么,但在类似情况下,我倾向于使用以下策略:>
1):在被测类中,将静态直接调用替换为对包装了静态调用本身的包级方法的调用:
public class ToBeTested{
public void myMethodToTest(){
...
String s = makeStaticWrappedCall();
...
}
String makeStaticWrappedCall(){
return Util.staticMethodCall();
}
}
2)在测试时监视被测类并模拟包装的包级方法:
public class ToBeTestedTest{
@Spy
ToBeTested tbTestedSpy = new ToBeTested();
@Before
public void init(){
MockitoAnnotations.initMocks(this);
}
@Test
public void myMethodToTestTest() throws Exception{
// Arrange
doReturn("Expected String").when(tbTestedSpy).makeStaticWrappedCall();
// Act
tbTestedSpy.myMethodToTest();
}
}
如果您需要更多了解,这里是我写的一篇关于间谍的文章,其中包含类似的案例: 解决方案
(I assume you can use Mockito though) Nothing dedicated comes to my mind but I tend to use the following strategy when it comes to situations like that:
1) In the class under test, replace the static direct call with a call to a package level method that wraps the static call itself:
public class ToBeTested{
public void myMethodToTest(){
...
String s = makeStaticWrappedCall();
...
}
String makeStaticWrappedCall(){
return Util.staticMethodCall();
}
}
2) Spy the class under test while testing and mock the wrapped package level method:
public class ToBeTestedTest{
@Spy
ToBeTested tbTestedSpy = new ToBeTested();
@Before
public void init(){
MockitoAnnotations.initMocks(this);
}
@Test
public void myMethodToTestTest() throws Exception{
// Arrange
doReturn("Expected String").when(tbTestedSpy).makeStaticWrappedCall();
// Act
tbTestedSpy.myMethodToTest();
}
}
