java - 如何在 RestTemplate 上应用 PowerMockito

Question

在我的代码中，我有 RestTemplate 的 New 运算符。让我知道如何在下面的 RestTemplate 上应用 Powermockito。

ResponseEntity<String> response =  new RestTemplate().exchange(requestEntity, String.class);

Answer 1

您需要使用PowerMockito.whenNew并使用mock返回模拟对象

参见example使用 PowerMockDemo 类和 Point new 运算符代替 RestTemplate

annotate unit test with @RunWith(PowerMockRunner.class) telling JUnit to use PowerMock runner and with @PrepareForTest(PowerMockDemo.class) telling PowerMock to get inside PowerMockDemo class and prepare it for mocking. Mocking is done with PowerMockito.whenNew(Point.class).withAnyArguments().thenReturn(mockPoint). It tells PowerMock when a new object from class Point is instantiated with whatever arguments to return mockPoint instead. It is possible to return different objects based on different arguments Point is created with withArguments() method
