如何使用 Mockito 捕获发送到存根方法的方法参数

Question

这是我的存根方法：

 Mockito.when(restTemplateMock.postForEntity(anyString(), any(), eq(String.class))).thenReturn(new ResponseEntity<String>(HttpStatus.OK));

如何获取发送到此方法的参数？上面的postForEntity 方法有3个参数。

Answer 1

final ArgumentCaptor<String> arg1Captor = ArgumentCaptor.forClass(String.class);
final ArgumentCaptor<Object> arg2Captor = ArgumentCaptor.forClass(Object.class);
final ArgumentCaptor<Class<?>> arg3Captor = ArgumentCaptor.forClass(Class.class);

Mockito.verify(restTemplateMock).postForEntity(arg1Captor, arg2Captor, arg3Captor);

Assert.assertEquals("Whatever", arg1Captor.getValue());
