katalon compare api response with database - katalon-studio

Question

I am not sure how to link test cases, add more verification.
I am thinking how to link both above, store the API response and after this completed successfully: ID, productid, productinfo.
Then query the database details, store it if possible (I have checkpoint created, not sure if this is the right approach), then verify values from API response same as the database column value.
I have object repository for sets of API message (GET/POST)
POST API to insert new product
Then 2 keywords to test the response of API matched the database records
connect to API and POST to insert the new product
connect to database and Get the table details
I have an individual test case to test the API POST message getting response 200 and run successfully. And another test case to connect to the database and query the table details.
===========
1. add product keyword groovy script
package Product
import static com.kms.katalon.core.testobject.ObjectRepository.findTestObject
import com.kms.katalon.core.annotation.Keyword
import com.kms.katalon.core.webservice.keyword.WSBuiltInKeywords as WS
import groovy.json.JsonBuilder
import groovy.json.JsonOutput
import groovy.json.JsonSlurper
public class API {
#Keyword
AddProduct() {
def result = WS.sendRequestAndVerify(findTestObject('AddProduct'))
return result
}
}
======================================
2. database groovy script
package database
import java.sql.*
import com.kms.katalon.core.annotation.Keyword
public class postgresHandler {
Connection c = null
Statement stmt = null
#Keyword
public void connectToPostgres(){
try {
Class.forName("org.postgresql.Driver")
String url = "jdbc:postgresql://localhost:5433/postgres?currentSchema=SCHEMA";
Properties props = new Properties();
props.setProperty("user","postgres");
props.setProperty("password","postgres");
c = DriverManager.getConnection(url, props);
} catch (Exception e) {
e.printStackTrace()
System.err.println(e.getClass().getName()+": "+e.getMessage())
System.exit(0)
}
System.out.println("Opened database successfully")
}
#Keyword
public void getProduct(){
try {
Class.forName("org.postgresql.Driver")
String url = "jdbc:postgresql://localhost:5433/postgres?currentSchema=SCHEMA";
Properties props = new Properties();
props.setProperty("user","postgres");
props.setProperty("password","postgres");
c = DriverManager.getConnection(url, props);
c.setAutoCommit(false)
System.out.println("Opened database successfully")
stmt = c.createStatement()
ResultSet rs = stmt.executeQuery( "select * from products.products;" )
while ( rs.next() ) {
String id = rs.getString("id")
String productid = rs.getString("productid")
String productInfo = rs.getString("productInfo")
System.out.println( "ID = " + id )
System.out.println( "productID = " + productid )
System.out.println( "productInfo = " + productInfo )
System.out.println()
}
rs.close()
stmt.close()
c.close()
} catch ( Exception e ) {
System.err.println( e.getClass().getName()+": "+ e.getMessage() )
System.exit(0)
}
System.out.println("Operation done successfully")
}
}

3. Test case to call add product keyword groovy script
import static com.kms.katalon.core.testobject.ObjectRepository.findTestObject
import com.kms.katalon.core.webservice.keyword.WSBuiltInKeywords as WS
result = CustomKeywords.'swisslog.KafkaRest.AddProduct'()
print(result)
WS.sendRequest(findTestObject('AddProduct'))
=====================================================
Test case to call database groovy script
import com.kms.katalon.core.configuration.RunConfiguration
CustomKeywords.'dsdatabase.postgresHandler.connectToPostgres'()
CustomKeywords.'dsdatabase.postgresHandler.getProduct'()
