Prerequisites for Connecting Tosca to a Database

Before you start the process to Connect to Database in Tosca Commander, ensure the following prerequisites are met:

1. Tosca Commander Installed – The Tosca Commander application should be installed and configured properly.
   
2. Database Access – You need valid credentials and permissions to access the database.
   
3. ODBC Drivers Installed – The correct ODBC driver for your database type (SQL Server, Oracle, MySQL, etc.) should be installed.
   
4. DSN Configuration – A Data Source Name (DSN) must be configured in the ODBC Data Source Administrator.
   

Once these elements are in place, you’re ready to establish a successful connection and automate database operations.

Step-by-Step Guide: How to Connect to Database in Tosca Commander

The process of connecting Tosca to a database can be divided into four main stages:

1. Configure ODBC
   
2. Open Connection in Tosca
   
3. Execute SQL Queries
   
4. Close the Connection
   

Let’s explore each step in detail.

Step 1: Configure ODBC

The first step to Connect to Database in Tosca Commander is to set up your ODBC connection. ODBC (Open Database Connectivity) allows Tosca to communicate with your database using a standard interface.

Follow these steps:

1. Open ODBC Data Source Administrator on your system.
   
2. Click on Add to create a new DSN.
   
3. Select the driver based on your database type (for example, SQL Server).
   
4. Provide the Server/Host Name where your database is located.
   
5. Test the connection to ensure it works correctly.
   
6. Save the DSN with a recognizable name (for instance, SQLServerForTosca).
   

This DSN name will later be referenced inside Tosca Commander while establishing the connection.

Step 2: Open Connection in Tosca Commander

After creating the DSN, open Tosca Commander and navigate to the Test Cases tab. Create a new folder and then a new test case inside it.

Now, add the TBox DB Expert Module from the Standard Modules section. This module provides the ability to open, execute, and close database connections within Tosca.

Under this module, perform the following actions to Connect to Database in Tosca Commander:

1. Open Connection – Drag and drop the “Open Connection” step from the module.
   
2. Fill in the following details:
   
   • Connection Name: Any custom name (for example, SQLServerDBConn).
     
   • DSN: Enter the DSN name created in the ODBC setup (SQLServerForTosca).
     
   • User ID and Password: Provide database login credentials (if required).
     
   • Driver: Specify the driver type, if necessary.
     

Once you fill out these parameters, Tosca can now communicate with the target database.

Step 3: Execute Queries

The next major step in learning how to Connect to Database in Tosca Commander involves executing SQL queries.

1. Add another step from the TBox DB Expert Module named SQL Statement.
   

      2. Under the Value column, write your SQL query. For example:

SELECT * FROM vehicleinfo;

2. Set ActionMode to Input and DataType to String.
   
3. Under the Result Table, specify how Tosca should handle and read query results.
   

Here’s how the configuration works:

• #1 – Represents the column header or the start of the first record.
  
• #2 – Refers to the first row of data returned by the query.
  
• $1 – Means the first data record (similar to #2).
  

Each cell (#1, #2, etc.) represents a column name from the query results. Instead of using numbers, you can also replace them with actual column names like make, EngPerf, or NoOfSeats.

When you Connect to Database in Tosca Commander, Tosca retrieves these results into buffers. To store them:

1. Under the Value column of the result table, assign a buffer name for each column.
   
2. Set the ActionMode to Buffer.
   
3. Tosca will store the returned values into these buffers for use in later test steps.
   

Step 4: Close the Connection

Once your query execution is complete, it’s essential to close the database connection. Leaving it open could consume system resources and potentially lock tables.

To close the connection:

1. Add the Close Connection step from the TBox DB Expert Module.
   
2. Set Value to True.
   
3. Ensure the Connection Name matches the one used earlier.
   

This step ensures Tosca terminates the session securely after all operations are finished.

Understanding Result Tables in Tosca

A critical part of mastering how to Connect to Database in Tosca Commander is understanding how Tosca interprets result tables.

Let’s break it down using the earlier example where we executed:

SELECT * FROM vehicleinfo;

If this query returns three columns: make, EngPerf, and NoOfSeats, then the result table in Tosca would look like this:

Here:

• #1, #2, and #3 correspond to the columns in the query.
  
• Each Buffer stores the data retrieved from the database.
  
• The Value column names (like MakeBuffer) act as variable placeholders that can be reused in subsequent test steps.
  

This design gives testers the flexibility to compare UI and backend values dynamically, enhancing the test coverage and reducing manual verification time.

Real-World Example of Tosca Database Automation

Consider an automotive company that maintains a large database of vehicles. During testing, the team must validate whether vehicle details displayed in the application match those stored in the backend database.

By learning how to Connect to Database in Tosca Commander, testers can automate this verification easily:

1. Query the database using Tosca to fetch vehicle details.
   
2. Store each returned column in Tosca buffers.
   
3. Compare the buffer values against UI fields captured in the test case.
   

This end-to-end automation ensures consistent and accurate testing while drastically reducing manual effort.

Moreover, these techniques form a core part of TOSCA Training, helping professionals gain practical experience in real-world automation projects.

Best Practices When You Connect to Database in Tosca Commander

1. Use Parameterization: Instead of hardcoding SQL queries, use parameters or buffers for flexibility.
   
2. Validate Connections: Always verify the connection before executing complex queries.
   
3. Manage Buffers: Use clear and descriptive buffer names to make test cases more readable.
   
4. Close Connections: Always close connections after use to free up resources.
   
5. Error Handling: Implement error-checking steps to handle connection failures gracefully.
   
6. Secure Credentials: Never store plain-text passwords in test cases. Use Tosca’s encrypted credential storage instead.
   

Following these best practices ensures that your database testing in Tosca is efficient, secure, and maintainable.
