Mockito单元测试之SpringMvc controller

创建测试类

package cn.******.jl.contract.api.controller;

import static org.junit.Assert.assertEquals;
import static org.mockito.Matchers.anyString;

@RunWith(MockitoJUnitRunner.class)
public class ContractControllerTest {
	private MockMvc mockMvc;

	@Mock
	ContractService contractService;

	@InjectMocks
	ContractController contractController;

	@Before
	public void setup() {

	}

	@Test
	public void getContractStatus_THEN_RETURN_SUCCESSFUL_NO_DATA() throws Exception {

另外还可以创建测试套件

package cn.******.jl.contract.api;

import org.junit.runner.RunWith;
import org.junit.runners.Suite;
import org.junit.runners.Suite.SuiteClasses;

import cn.******.jl.contract.api.controller.ContractControllerTest;

@RunWith(Suite.class)
@SuiteClasses({ContractControllerTest.class})
public class TestSuits {
}
