Unable to set database credentials on katalon default database settings using setProperty

Hello, I’m trying to edit the default database settings programmatically by using the following line in a test case
bundleSetting.setProperty(“USER”, “username”)
The test case passes and the value gets changed in the default database settings. However, the value is being inserted with quotes (“username”) and since my database username does not actually have quotes, the database connection is failing. I tried escaping the quotes but that did not work.
I’m guessing that when it inserts into the default database settings, it should not be adding quotes?
Please let me know if there is a way to fix this by not having quotes inserted.


How to perform Database Testing using Katalon Studio

Katalon Studio allows users to create custom keywords to address specific needs. With custom keywords, you can connect to databases and perform database testing. This tutorial describes details on how to create custom keywords for database testing in Katalon Studio.

Below is a code sample demonstrating how to

  • establish a database connection
  • execute a query
  • close the connection
package com.database
import java.sql.DriverManager
import java.sql.ResultSet
import java.sql.Statement
import com.kms.katalon.core.annotation.Keyword
import com.mysql.jdbc.Connection
public class DemoMySql {
private static Connection connection = null;
* Open and return a connection to database
* @param dataFile absolute file path
* @return an instance of java.sql.Connection
//Establishing a connection to the DataBase
def connectDB(String url, String dbname, String port, String username, String password){
//Load driver class for your specific database type
String conn = "jdbc:mysql://" + url + ":" + port + "/" + dbname
//String connectionString = "jdbc:sqlite:" + dataFile
if(connection != null && !connection.isClosed()){
connection = DriverManager.getConnection(conn, username, password)
return connection
* execute a SQL query on database
* @param queryString SQL query string
* @return a reference to returned data collection, an instance of java.sql.ResultSet
//Executing the constructed Query and Saving results in resultset
def executeQuery(String queryString) {
Statement stm = connection.createStatement()
ResultSet rs = stm.executeQuery(queryString)
return rs
//Closing the connection
def closeDatabaseConnection() {
if(connection != null && !connection.isClosed()){
connection = null
* Execute non-query (usually INSERT/UPDATE/DELETE/COUNT/SUM...) on database
* @param queryString a [SQL](https://mindmajix.com/sql-server-dba-training#:~:text=Engage%20in%20SQL%20Server%20DBA,Gain%2) statement
* @return single value result of SQL statement
def execute(String queryString) {
Statement stm = connection.createStatement()
boolean result = stm.execute(queryString)
return result

The Custom Keywords file will look like the following:

Katalon Custom Keywords

You can add the sample code above to your keyword file and modify the details as appropriated. Refer to these links for the formats of database connection strings:

Use Defined Keywords in Test Cases for DB Testing

  1. Create new custom keywords for database connection (see above).

  2. Copy the DB script provided above and paste it into the new keyword editor as illustrated below:Katalon Defined Keywords
