假设我有一个名为Util的类,其中包含静态字段:
public class Util {
public static field = Param.getValue("param1");
}
并且Param类看起来像这样:
public class Param {
public static field = SomeClass.getValue("someValue");
}
我想在Util中模拟和存储Param.getValue(" param1"),但同时我想要抑制Param类的静态初始化。我怎样才能做到这一点?
这是我的第一次尝试,但它无法正常工作
@RunWith(PowerMockRunner.class)
@PrepareForTest({Param.class})
@SuppressStaticInitializationFor("py.com.company.Param")
public class Test {
@Test
public void testSomeMethod() {
PowerMockito.mockStatic(Param.class);
when(Param.getValue("value1")).thenReturn("someValue1");
}
}
答案 0 :(得分:1)
这对我有用。我没有输出,SomeClass#getValue
如果没有@SuppressStaticInitializationFor
:
@RunWith(PowerMockRunner.class)
@SuppressStaticInitializationFor({"so35047166.Param"})
@PrepareForTest({Param.class})
public class UtilTest {
@Before
public void setUp() throws Exception {
PowerMockito.mockStatic(Param.class);
}
@Test
public void testFoo() throws Exception {
final Util util = new Util();
assertEquals("Util#foo", util.foo());
assertEquals(null, Util.field);
}
}
使用:
// all in package so35047166;
public class Util {
public static String field = Param.getValue("param1");
public String foo() {
return "Util#foo";
}
}
public class Param {
public static String field = SomeClass.getValue("someValue");
public static String getValue(final String in) {
System.out.println("Param#getValue");
return "Param#getValue";
}
}
public class SomeClass {
public static String getValue(final String in) {
System.out.println("SomeClass#getValue");
return "SomeClass#getValue";
}
}
