Integration Test in Grails

To write code Integration Test we need 2 steps:
- Create new Object and Save them to database
- Create some functions test

• Send request and receipt response.
• Create new functions test require parameters

* Some special cases
And run by command line
grails test-app -integration -Dgrails.env=test ProfileServiceControllerTests

Step 1:
Create new object and save them to database. Please create object relation and save them before you save main object.

Example:
Students is main object relate with Subjects. Please create new Subjects and save it before you save Students object.

Step 2: Create some function tests
Send request by controller


def controller = new FeedServiceController()
controller.response.reset()      
        
controller.request.requestMethod = HttpMethod.GET
controller.params.sessionToken =  sessionToken
        
controller.feedBySessionToken()
JSONElement responseJSON = controller.response.json
        
println responseJSON.toString(4)

1. New controller and reset all response.
2. Set params for request.
3. Call function of controller
4. Get response and check from response.

* Some special cases:
1. Post file for controller to test upload file


 File testFile = new File("web-app/images/favicon.ico")
 MultipartFile file = new MockMultipartFile("avatar", 'avarta.ico', 'image/ico', testFile.readBytes())

 def controller = new ProfileServiceController()
 controller.response.reset()

 //Tets for vartar empty
 controller.request.setMethod("POST");
 controller.params.sessionToken = sessionToken
      
 controller.updateAvatar()
 JSONElement json = controller.response.json

New file by File and MultipartFile (note: 'avarta' word is field name that controller getFile. controller.getFile('avarta'))

New controller and send request with params is token

2. Test with function have token
- Send request to get token
- Send other request to get response to test
(You must reset response and request params by 2 function.  controller.response.reset() and controller.params.clear())

Unit Test in Grails

To test Unit Test we need 2 steps:
- Create new Object in setUp function.
- Create some function tests.

Step 1:
In this example, I create class from abstract class. With class Feed is abstract class.


void setUp() {
        feed = [jsonForRelatedEntity: { -> 
                [
                    id: 1,
                    title: "Feed Title", 
                    date: new Date('2010/10/11')                 
                ]
            }] as Feed
    }

Step 2:
Create some function test.


/**
    * Test function json
    * @author tien.nguyen
    */
    void testJSON() {
        def json = feed.json()
        
        assertEquals "Feed Title",  json.title
        assertEquals new Date('2010/10/11'), json.date        
        
        println json
    }

Good luck to you.

Grails - Connect with mysql

Default Grails connect with HSQLDB. But we need connect mysql
Go to conf folder. Change file DataSoure.groovy


dataSource {
    pooled = true
    driverClassName = "com.mysql.jdbc.Driver"
    username = "root"
    password = "password"
    dialect = "org.hibernate.dialect.MySQL5InnoDBDialect"
}

Go to environment change url database
url = "jdbc:mysql://localhost:3306/racetrack_dev"

Go to file BuildConfig.groovy
uncomment runtime dependencies with mysql 
When run grails will download mysql driver.

Check mysql database

Good luck to you

Groovy is programming language was inherit from java. It don't replace Java that it is support java. It help some java developer short their coding.

- Extract file that you download
- Set Environment variable JAVA_HOME and GRAILS_HOME: Please go to /etc/environment add JAVA_HOME and GRAILS_HOME (is path go to folder content java and grails that you extract). Remember set PATH for JAVA_HOME and GRAILS_HOME go to bin folder. Continue run "source   /etc/environment" to update new environment variable.
(Please see introduction in link from Grails: http://grails.org/Installation)
