Tosca Distributed Execution (DEX) Setup Guide

 Tosca Distributed Execution (DEX) Setup Guide

What is Tosca Distributed Execution (DEX)?

Tosca Distributed Execution (DEX) allows you to run Tosca tests in parallel across multiple machines or agents, speeding up test execution and enabling scalability for large test suites.


Why Use DEX?

Parallel Test Execution: Run multiple tests simultaneously.


Scalability: Distribute tests across multiple environments.


Resource Optimization: Utilize multiple machines efficiently.


Faster Feedback: Reduce total test runtime.

Pre-requisites

Tosca Commander installed on all participating machines.


Network connectivity between Tosca Controller and Execution Agents.


Tosca Executor (Execution Agents) licenses.


Synchronized Tosca versions across machines.


Proper permissions for communication (firewalls, ports).


Components of DEX

Component Description

DEX Controller Central Tosca instance managing distributed execution

DEX Executor Remote agents that execute test cases

Database Shared repository where test cases and results are stored


Step-by-Step Setup

1. Prepare Tosca Commander on All Machines

Install Tosca Commander on the Controller machine.


Install Tosca Commander Executor on all remote machines (Executors).


Ensure all machines use the same Tosca version.


2. Configure DEX Controller

Open Tosca Commander on the Controller machine.


Go to Settings > Distributed Execution.


Enable Distributed Execution option.


Configure the Controller Hostname/IP and Port.


Ensure Controller can communicate with Executors.


3. Configure DEX Executors

On each remote machine, open Tosca Commander Executor.


Go to Settings > Distributed Execution.


Enter the Controller's Hostname/IP and Port.


Register the Executor with the Controller.


Ensure Executors have the necessary permissions.


4. Network and Firewall Configuration

Open the required network ports (default is 40006).


Allow inbound/outbound communication between Controller and Executors.


Verify connectivity using ping or telnet.


5. Assign Test Cases for Distributed Execution

In Tosca Commander, organize your test cases.


Define execution lists and assign them to Executors.


Use the Distributed Execution view to monitor test execution status.


6. Start Distributed Execution

From the Controller, start execution.


Tests are distributed automatically to Executors.


Monitor progress and collect test results centrally.


Tips for Effective DEX Setup

Keep Tosca versions consistent across all machines.


Ensure all Executors have access to necessary test data and environments.


Use stable network connections to avoid execution interruptions.


Regularly update Executor machines with patches and licenses.


Monitor resource utilization to balance load.


Troubleshooting Common Issues

Issue Possible Cause Solution

Executors not connecting Firewall blocking ports Open port 40006 and allow traffic

Version mismatch Different Tosca versions Update all machines to same version

Execution hangs or fails Network instability Check network and retry

Tests not distributed Incorrect Controller/Executor config Verify configuration settings


Summary

Step Description

Install Tosca On Controller and Executor machines

Configure Controller Enable DEX and set host/port

Configure Executors Register with Controller

Configure Network Open necessary ports and permissions

Assign Tests Distribute test cases

Run and Monitor Execute tests and collect results

Feeling Stuck in Manual Testing? Here’s Why You Should Learn Automation Testing

Feeling Stuck in Manual Testing? Here’s Why You Should Learn Automation Testing Are you feeling like your manual testing career is hitting a ceiling? You’re not alone. Many QA professionals start their careers in manual testing but soon realize the need to level up. If you’re wondering what’s next, automation testing might just be the breakthrough you need. Why Manual Testing Isn’t Enough Anymore Manual testing is essential, especially in exploratory, usability, and ad-hoc testing scenarios. But as applications grow more complex and development cycles become shorter, manual testing can’t keep up. Companies are looking for faster, more efficient testing methods—and that’s where automation comes in. Here are a few signs that you're stuck in manual testing: Repeating the same test cases for every build Working on tight deadlines with limited test coverage Seeing peers move ahead with automation skills Lack of growth in responsibilities or pay scale If any of this sounds familiar, it...
