Understanding the Architecture of OpenTest: A Comprehensive Guide

As we explored the features and benefits of OpenTest in the previous sections, it's essential to understand the underlying architecture that makes it all work. In this section, we'll dive into the architecture of OpenTest and provide a comprehensive guide on how it's designed to support scalable and efficient test automation.

Overview of the OpenTest Architecture The OpenTest architecture is designed to be modular, scalable, and flexible. It consists of several components that work together to provide a robust test automation framework.

This architecture enables OpenTest to adapt to various test automation scenarios and environments, offering distributed testing and parallelization features.

Components of the OpenTest Architecture

Here are the main components of the OpenTest architecture:

• The OpenTest server

A Node.js application that manages test execution, implements the OpenTest web UI, and exposes an API to integrate with external systems (CI/CD, reporting, test management).

• The test actor

This is a description of a Java application that follows instructions from the OpenTest server to execute test steps. The application can support multiple actors participating in a test, and the actors can be deployed on any machine in any network or in the cloud. The communication between the test actor and the OpenTest server is always initiated by the actor itself, which simplifies the setup in scenarios where the actors are running behind a firewall or in a network that is not accessible from the machine running the sync server (which is often the case for many labs and test environments).

• The test repository

A directory with a predefined structure that typically includes various test assets such as test files, data files, scripts, templates for test sessions, etc. This directory is usually under source control.

How the Components Interact Here's a high-level overview of how the components interact:

1. Test Server: The test server receives a test request from a user and creates a new test session.
2. Test Actor: The test server assigns the test session to a test actor, which executes the test and reports the results back to the test server.
3. Test Repository: The test actor retrieves test assets from the test repository and uses them to execute the test.
4. Database: The test server stores the test results in the database, which can be used for reporting and analytics.

Test Server Architecture

The test server is the central component of the OpenTest architecture. It's responsible for managing test sessions, executing tests, and providing a web-based interface for users to interact with.

Test Server Components Here are the main components of the test server:

• Web Server: The web server provides a web-based interface for users to interact with the test server.
• Test Session Manager: The test session manager is responsible for creating and managing test sessions.
• Test Executor: The test executor is responsible for executing tests and reporting the results back to the test session manager.
• Database Interface: The database interface is used to store test results and retrieve test metadata.

Test Actor Architecture Test actors are the components that execute tests on behalf of the test server. They can be thought of as "workers" that perform the actual testing tasks.

Test Actor Components Here are the main components of a test actor:

• Test Executor: The test executor is responsible for executing tests and reporting the results back to the test server.
• Test Asset Manager: The test asset manager is responsible for retrieving test assets from the test repository and using them to execute the test.
• Test Environment: The test environment is the environment in which the test is executed.

Test Repository Architecture The test repository is a centralized storage system that stores all test assets, including test scripts, test data, and test results.

Test Repository Components Here are the main components of the test repository:

• Test Asset Store: The test asset store is responsible for storing test assets, including test scripts, test data, and test results.
• Test Asset Manager: The test asset manager is responsible for retrieving test assets from the test asset store and providing them to the test actors.

Database Architecture The database is used to store test results, test metadata, and other relevant data.

Database Components Here are the main components of the database:

• Test Result Store: The test result store is responsible for storing test results.
• Test Metadata Store: The test metadata store is responsible for storing test metadata, including test scripts, test data, and test environments.

Understanding the architecture of OpenTest is essential for designing and implementing scalable and efficient test automation solutions. By understanding the components and how they interact, you can design and implement test automation solutions that meet your specific needs. Remember to consider the scalability, flexibility, and maintainability of your test automation solution when designing and implementing it.

└── test-repo

    └── ...

Best Practices

When working on multiple test automation projects, it's recommended to have multiple server working directories, each pointing to a project-specific test repository. For example:

C:\opentest

├── server-proj1

│   └── server.yaml

├── server-proj2

│   └── server.yaml

└── test-repo-proj1

│   └── ...

└── test-repo-proj2

    └── ...

The server.yaml file for each project should contain the project-specific test repository directory. For example:

testRepoDir: "C:/opentest/test-repo-proj1"

Parameter List

The server.yaml file can contain various parameters that control the behavior of the OpenTest server. Some of the essential parameters include:

• acquireActorsTimeoutSec: The number of seconds a test session will wait to acquire the necessary test actors before it is cancelled.
