Grails- spock : turn setup method as normal method - grails

Question

I am trying to write unit for one of my grails service method, the unit test is like
#Shared instance1, instance2, instance3
class testClass extends Specification {
def setup() {
// initaiting some value here
instance1 = new Initate(one:"one")
instance2 = new Initate(one:"one")
instance3 = new Initate(one:"one")
}
def "testmethodcall"() {
//testsetup()
when:
def result = someMethod(value1) // Here is the error
then:
result==value2
where:
value | value1 | value2
instance1 | instance2 | instance3
}
}
for some reason we planned to move the codes inside this setup method to another method and plan to call where it is required, like this
#Shared instance1, instance2, instance3
class testClass {
def testsetup() {
// initialize the code what we initialize in setup
// initaiting some value here
instance1 = new Initate(one:"one")
instance2 = new Initate(one:"one")
instance3 = new Initate(one:"one")
}
def "testmethodcall"() {
testsetup()
when:
def result = someMethod(value1) // Here is the error
then:
result==value2
where:
value | value1 | value2
instance1 | instance2 | instance3
}
}
As of now it is fine, the method call is working fine, even variable were been initialized, but when I trying to use the data column values it is returning null values, but when I change to setup() method I getting the real values. Can someone explain me and How can I able to change the setUp method as normal method

There are few things to note down:-
setup() - is used to run with every test case
setupSpec() - is used to run once for a test class / unit
shared - is visible throughout.And hence must be initialized once, Hence must be within worked upon in setupSpec and not within setup.
cleanup() - is run with every test case
cleanupSpec - is run in last, after all the test cases has run.
Only #Shared and static variables can be accessed from within a where: block.
Seperate inputs and outputs expected with double pipes ||
Apart from these point, in your code testmethodcall method is having syntax errors.
no comparison is done
expect: is missing
why def value is there ,whereas we use data tables variables are declared automatically
Also, value2 is used no where
Also, you stated that you are able to run test cases successfully with above code when setup() method is there, it's just passing silently without failing as both the value and value1 are null.
Below is a modified version of your code
def "test methodcall"(){
setup()
expect:
value == someMethod(value1) // Here is the error
println '----instance1----'+value
println '----instance2----'+value1
println '----instance1----'+instance1
println '----instance2----'+instance2
// instance1 == instance2
where:
value | value1
instance1 | instance2
}
Now see the println output and you will understand the issue.Hope this would get you answer.
