How to test Grails service using Spock?
提问by prayagupd
I have a EncouragementService.groovywith following method
我有EncouragementService.groovy以下方法
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. Pass the list of users to encourageUsers(...)method and check whatever I want with the result.
为了在 JAVA Universe 中测试上述代码，使用 JUnit 我首先会在 setup 中创建两个或三个用户。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 takes testing to whole another level, where you can test the behavior (adheres to BDD). The test class would look like:
Spock 单元测试：
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）。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 pluginto build the users.
使用build-test-data 插件来构建用户。
@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. Your test has to extend Specification and you might want to familiarize yourself with Spock's keywords.
我还对代码进行了一些更改，使其成为适当的 spock 规范。您的测试必须扩展 Specification 并且您可能想要熟悉Spock 的关键字。
