[英]How to test Grails service using Spock?
I have a EncouragementService.groovy
with following method 我有一个
EncouragementService.groovy
,方法如下
class EncouragementService {
def stripePaymentService
def encourageUsers(List<User> users){
if(null != users && users.size()>0){
for(User user : users){
//logic
stripePaymentService.encourage(user)
//
}
}
}
}
To test above code in JAVA universe, using JUnit I would first create two or three users in setup. 要在JAVA Universe中测试上面的代码,使用JUnit我首先要在安装程序中创建两个或三个用户。 Pass the list of users to
encourageUsers(...)
method and check whatever I want with the result. 将用户列表传递给
encourageUsers(...)
方法并检查我想要的结果。
How can I achieve the same thing here in grails, 我怎样才能在grails中实现同样的目标,
import com.github.jmkgreen.morphia.Datastore;
@TestFor(EncouragementService)
class EncouragementServiceSpec {
def morphiaService = new MorphiaService()
void testEncourageUsers() {
List<User> users = createUsers();
encouragementService.(users)
//
}
def createUsers(){
Datastore datastore = morphiaService.dataStoreInstance()
def user = new User()
user.setName("Prayag Upd")
//
datastore.save(user)
[user]
}
}
I am using spock:0.7 我正在使用spock:0.7
plugins {
test(":spock:0.7") { exclude "spock-grails-support" }
}
Service class can be optimized as below: 服务类可以优化如下:
class EncouragementService {
def encourageUsers(List<User> users){
if(users){ //Groovy truth takes care of all the checks
for(user in users){
//logic
}
}
}
}
Spock Unit Test: Spock单元测试:
Spock takes testing to whole another level, where you can test the behavior (adheres to BDD). Spock将测试提升到另一个级别,您可以在其中测试行为(遵循BDD)。 The test class would look like:
测试类看起来像:
import spock.lang.*
@TestFor(EncouragementService)
@Mock(User) //If you are accessing User domain object.
class EncouragementServiceSpec extends Specification{
//def encouragementService //DO NOT NEED: mocked in @TestFor annotation
void "test Encourage Users are properly handled"() {
given: "List of Users"
List<User> users = createUsers()
when: "service is called"
//"service" represents the grails service you are testing for
service.encourageUsers(users)
then: "Expect something to happen"
//Assertion goes here
}
private def createUsers(){
return users //List<User>
}
}
Use the build-test-data plugin to build the users. 使用build-test-data插件构建用户。
@TestFor(EncouragementService)
@Build(User)
class EncouragementServiceSpec extends Specification {
def "encourage users does x"() {
given:
def users = createUsers();
when:
service.encourageUsers(users)
then:
// assert something
}
def createUsers(){
[User.build(), User.build(), User.build()]
}
}
I've also made a couple of changes to the code to make it a proper spock specification. 我还对代码进行了一些更改,使其成为一个合适的spock规范。 Your test has to extend Specification and you might want to familiarize yourself with Spock's keywords .
您的测试必须扩展规范,您可能希望熟悉Spock的关键字 。
