Katalon Posibble to assert response = data? - groovy

Question

I store json test data in excel file.
Make use of apache POI to read the json data and parse it as request body, call it from katalon.
Then I write many lines of assertion (groovy assert) to verify each line response = test data.
Example:
Assert test.responseText.fieldA == 'abc'
Assert test.responseText.fieldB == 'xyz'
And so on if I have total of 20 fields.
I'm thinking of there is better way to make use of the json data stored in data file.
To assert the response = test data. So I can save alot of time to key in each line and modify them is the test data changed.
Please advise if this can be achieved?

Answer 1

Here is an example: you have two excel sheets - current values and expected values (values you are testing against).
Current values:
No. | key | value
----+-----+------
1 a 100
2 b 6
3 c 13
Expected values:
No. | key | value
----+-----+------
1 a 100
2 b 6
3 c 14
You need to add those to Data Files:
The following code will compare the values in the for loop and the assertion will fail on the third run (13!=14):
def expectedData = findTestData("expected")
def currentData = findTestData("current")
for(i=1; i<=currentData.getRowNumbers(); i++){
assert currentData.getValue(2, i) == expectedData.getValue(2, i)
}
Failure message should look like this:
2020-07-02 15:16:40.471 ERROR c.k.katalon.core.main.TestCaseExecutor - ❌ Test Cases/table comparison FAILED.
Reason:
Assertion failed:
assert currentData.getValue(2, i) == expectedData.getValue(2, i)
