[英]How to write test case for Spring boot controller using spock framework
[英]How to create a generic CRUD controller test in Spock
甚至可以在 Spock 中为 Spring controller 创建通用单元测试吗? 我在 Spring Boot 中有一个抽象的 controller,它由一些特定的控制器扩展。 结果是每个 controller 都有相同的 CRUD 实现。 所以,现在我想为这些控制器创建类似的单元测试,但我不能在 Spock 测试中使用构造函数。 我收到错误
CrudControllerTest.groovy
Error:(16, 5) Groovyc: Constructors are not allowed; instead, define a 'setup()' or 'setupSpec()' method
IngredientControllerTest.groovy
Error:(7, 5) Groovyc: Constructors are not allowed; instead, define a 'setup()' or 'setupSpec()' method
对于以下代码
abstract class CrudControllerTest<T, R extends JpaRepository<T, Long>, C extends CrudController<T,R>> extends Specification {
private String endpoint
private def repository
private def controller
private MockMvc mockMvc
CrudControllerTest(def endpoint, R repository, C controller) {
this.endpoint = endpoint
this.repository = repository
this.controller = controller
this.mockMvc = MockMvcBuilders.standaloneSetup(controller).build()
}
def "Should get 404 when product does not exists"() {
given:
repository.findById(1) >> Optional.empty()
when:
def response = mockMvc.perform(MockMvcRequestBuilders.get(endpoint + '/1')).andReturn().response
then:
response.status == HttpStatus.NOT_FOUND.value()
}
}
class IngredientControllerTest extends CrudControllerTest<Ingredient, IngredientRepository, IngredientController> {
IngredientControllerTest() {
def repository = Mock(IngredientRepository)
super("/ingredients", repository, new IngredientController(Mock(repository)))
}
}
这里还有其他方法可以在 Spock 中实现通用单元测试吗?
您不能将构造函数用于Specifications
,而是可以使用模板方法模式。 要么使用单独的方法:
abstract class CrudControllerTest extends Specification {
private String endpoint
private def repository
private def controller
private MockMvc mockMvc
def setup() {
endpoint = createEndpoint()
repository = createRepository()
controller = createController()
mockMvc = MockMvcBuilders.standaloneSetup(controller).build()
}
abstract createEndpoint()
abstract createRepository()
abstract createController()
def "Should get 404 when product does not exists"() {
given:
repository.findById(1) >> Optional.empty()
when:
def response = mockMvc.perform(MockMvcRequestBuilders.get(endpoint + '/1')).andReturn().response
then:
response.status == HttpStatus.NOT_FOUND.value()
}
}
class IngredientControllerTest extends CrudControllerTest<Ingredient, IngredientRepository, IngredientController> {
def createEndpoint() {
"/ingredients"
}
def createRepository {
Mock(IngredientRepository)
}
def createController() {
new IngredientController(repository)
}
}
或者使用返回所有内容的方法,这会更好一些,因为您的某些值需要引用另一个值:
abstract class CrudControllerTest extends Specification {
private String endpoint
private def repository
private def controller
private MockMvc mockMvc
def setup() {
(endpoint, repository, controller) = createSut()
mockMvc = MockMvcBuilders.standaloneSetup(controller).build()
}
abstract createSut()
def "Should get 404 when product does not exists"() {
given:
repository.findById(1) >> Optional.empty()
when:
def response = mockMvc.perform(MockMvcRequestBuilders.get(endpoint + '/1')).andReturn().response
then:
response.status == HttpStatus.NOT_FOUND.value()
}
}
class IngredientControllerTest extends CrudControllerTest<Ingredient, IngredientRepository, IngredientController> {
def createSut() {
def repo = Mock(IngredientRepository)
["/ingredients", repo, new IngredientController(repository)]
}
}
