Groovy/Spock- Data driven test for values from excel sheet - groovy

Question

I could definitely use some help here. I have an excel sheet from where I am getting values and doing some validations on them, I am checking if both values match. My code is as follows:
#Unroll ("For #calcToCheck.tr_date_class")
def "I check flag value #calcToCheck.tr_date "(CalculationClass calcToCheck) {
expect:
flag==calcToCheck.result
where:
calcToCheck << calInputParameters()
}
def calInputParameters() {
//some logic to get values from SQL and getting flag
return calcsToCheck
}
This runs fine for one row but when I insert multiple rows in excel sheet, I just get output as one result. I would like to see each row's result. I thought adding #Unroll would take care of it showing me what rows it is displaying the results but it does not.

Answer 1

Here is some sample code you can run and then modify. Because you did not explain where flag comes from, I was just making up something, assuming it is also an unrolled parameter checked against whatever your helper method delivers.
package de.scrum_master.stackoverflow
import spock.lang.Specification
import spock.lang.Unroll
/**
* See https://stackoverflow.com/q/48410722/1082681
*/
class PseudoExcelTableTest extends Specification {
#Unroll//("For #calcToCheck.tr_date_class")
def "I check flag value #calcToCheck.tr_date"(CalculationClass calcToCheck, int flag) {
expect:
flag == calcToCheck.result
where:
calcToCheck << calInputParameters()
flag << [11, 22, 33]
}
def calInputParameters() {
def calcsToCheck = new ArrayList<CalculationClass>()
calcsToCheck.addAll(
new CalculationClass(result: 11, tr_date: "eleven", tr_date_class: "short"),
new CalculationClass(result: 22, tr_date: "twenty-two", tr_date_class: "long"),
new CalculationClass(result: 33, tr_date: "thirty-three", tr_date_class: "normal")
)
return calcsToCheck
}
static class CalculationClass {
int result
String tr_date
String tr_date_class
}
}
As for the unrolled method names, you mix up two things:
Naming the methods via #Unroll parameter, which in my example would result in method names For short, For long, For normal. This has preference over the second option:
Naming the methods via normal method name, which in my example would result in method names I check flag value eleven, I check flag value twenty-two, I check flag value thirty-three.
I chose option 2 by commenting out the unroll parameter.
