无法测试我的@RestController：嵌套异常是org.springframework.beans.factory.NoSuchBeanDefinitionException：

如何解决无法测试我的@RestController：嵌套异常是org.springframework.beans.factory.NoSuchBeanDefinitionException：

Spring Boot应用。

我的控制器：

@RestController
public class ProductsController {
    private ProductRepository productRepository;

   @GetMapping("/products")
    public List<Product> getAllProducts() {

这是我对Rest控制器的测试：

import org.junit.Test;
import org.junit.jupiter.api.extension.ExtendWith;
import org.junit.runner.RunWith;
import org.mockito.InjectMocks;
import org.mockito.junit.jupiter.MockitoExtension;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.junit4.springrunner;
import java.util.Arrays;
import java.util.List;
import static org.junit.Assert.assertTrue;
import static org.mockito.Mockito.when;

@ExtendWith(MockitoExtension.class)
@RunWith(springrunner.class)
public class ProductRestControllerIntegrationTest {
    @Autowired
    private ProductRepository productRepository;

    @InjectMocks
    ProductsController productsController;

    @Test
    public void testFindAll() {

但是启动测试testFindAll时出现运行时错误

解决方法

尝试在@RunWith（SpringRunner.class）下将@SpringBootTest添加到您的测试配置中
