模拟带有参数[duplicate]的静态方法

Question

有没有办法用参数模拟静态方法。

我看到了很多关于这个问题的问题，但是我找不到任何与之相关的问题。

可以使用PowerMockito模拟静态方法。这里有一个完整的例子。

@RunWith(PowerMockRunner.class)
@PrepareForTest(Helper.class)
public class YourTestCase {
   @Test
   public void testMethodThatCallsStaticMethod() {
      // mock all the static methods in a class called "Static"
      PowerMockito.mockStatic(Helper.class);
      // use Mockito to set up your expectation
      Mockito.when(Helper.getName("abc")).thenReturn("foo");

      // execute your test
      String result = Helper.getName("abc");

      //assert the result
      Assert.assertEquals("foo", result);

      // to start verifying behavior
      PowerMockito.verifyStatic(Mockito.times(1));
      // IMPORTANT:  Call the static method you want to verify
      Helper.getName("abc");
  }
}
