Grails 3.0.6 java.lang.IllegalStateException on any integration test - grails

Question

import grails.test.mixin.integration.Integration
import spock.lang.Specification
#Integration
class MySpec extends Specification {
def setup() {
}
def cleanup() {
}
void "test something"() {
expect:"tests a"
true
}
}
MySpec > test something FAILED
java.lang.IllegalStateException
Caused by: org.springframework.beans.factory.BeanCreationException
Caused by: org.springframework.beans.factory.BeanCreationException
Caused by: org.springframework.beans.factory.BeanCreationException
Caused by: java.lang.NullPointerException
1 test completed, 1 failed
:integrationTest FAILED
:mergeTestReports
I run
"test-app -integration MySpec" command
Is that an error in grails or I do smth wrong?
UPDATE!
I found a solution - just add
testCompile "org.grails.plugins:hibernate"
to build.gradle

Answer 1

Testing was never so easy and intuitive before the use of Spock.We can always test the exceptions in grails Spock Testing. For example we have a method which throws exception like :
String getUserType(int age){
if(age<=0){
throw new MyException("Invalid age")
}else if( age>0 && age<50){
return "Young"
}else{
return "Old"
}
}
Now we will write the test case of this method for checking whether exception is thrown for invalid inputs or not.
def "exception should be thrown only for age less than or equal to 0"{
given:
String type = getUserType(34)
expect:
type == "Young"
notThrown MyException
when:
type = getUserType(0)
then:
thrown MyException
}
This is how we have tested whether exception is thrown for invalid input or not.
Hope it helps
