Object is not saved in spock integration test - grails

Question

I have a Token entity:
class Token {
/**
* Constants for various namespaces
*/
public static final String NS_PASSWORD_RESET = "pass-reset";
/**
* A simple string unlimited in content that defines a scope of the token
*/
String namespace
/**
* This fields holds an identifier for anything specific that the process might need
*/
Long identifier
/**
* The actual token itself
*/
String token
Timestamp dateCreated
Timestamp lastUpdated
Timestamp expiration
static mapping = {
autoTimestamp true
}
static constraints = {
}
}
and a service class with a following method:
def creareNewToken(String ns, int timeout) {
def token = new Token()
token.setNamespace(ns)
token.setToken(this.generateToken(15))
//persist the object
token.save(flush: true)
return token
}
I created an integration test for the service class:
class TokenServiceIntegrationSpec extends IntegrationSpec {
TokenService tokenService
def "test creareNewToken"() {
when:
def token = tokenService.creareNewToken(Token.NS_PASSWORD_RESET, 60)
then:
token instanceof Token
token.getNamespace() == Token.NS_PASSWORD_RESET
token.getToken().length() == 15
token.getDateCreated() == ''
}
}
When I execute the test, I get:
Failure: test
creareNewToken(com.iibs.security.TokenServiceIntegrationSpec)
| Condition not satisfied:
token.getDateCreated() == ''
| | |
| null false
com.iibs.security.Token : (unsaved)
at com.iibs.security.TokenServiceIntegrationSpec.test creareNewToken(TokenServiceIntegrationSpec.groovy:31)
What could be the reason for this problem? Is seems like the object is actually not saved, and, of coarse, the dateCreated is not populated as well. My question is why it is not saved? I have number of other tests that build in a similar way, and they work without any issue.
Thank you for any advice.

Answer 1

You have two fields (identifier and expiration) which you are not setting. By default every field is not nullable. Try adding:
assert token.save(...)
To check if your object is really being saved.
If you want them to accept null as a value you need to specify it in your constraints
static constraints = {
identifier nullable: true
expiration nullable: true
}

Try adding failOnError:true to the options on save, if only for debugging purposes. The resulting stack trace will usually point out if a field is not set, etc.
def creareNewToken(String ns, int timeout) {
def token = new Token()
token.setNamespace(ns)
token.setToken(this.generateToken(15))
//persist the object
token.save(flush: true, failOnError:true)//this will throw an error if save does not occur
return token
}
