Quality Center: A Comprehensive Test Management Tool

Quality Center, formerly known as Test Director, is a powerful test management tool designed to streamline the software testing process. Developed by Mercury Interactive and currently maintained by HP as Application Lifecycle Management (ALM), Quality Center offers a range of functionalities that enable efficient test planning, execution, and tracking. This article will delve into the key features, history, architecture, editions, and workflow of Quality Center.

Functionality

Quality Center serves as a centralized repository for managing functional, performance, and security test scripts. It allows Quality Assurance (QA) teams to define and track test cases, execute manual and automated tests, emulate business processes, and run tests unattended with tools like QuickTest Professional (QTP). By consolidating all testing activities in one place, Quality Center enhances collaboration and ensures comprehensive test coverage.

Project Management

In addition to test management, Quality Center also facilitates project management. It enables teams to define and manage project milestones, deliverables, and resources. Project managers can use the tool to monitor project health, track progress, and allocate resources effectively. Quality Center provides real-time visibility into the current status of the product, enabling product owners to make informed decisions and prioritize their efforts.

History

Quality Center has a rich history. It was originally developed as Test Director by Mercury Interactive. Over the years, it has undergone several versions and rebranding efforts and is now known as HP ALM. The tool has evolved to meet the changing demands of the software development industry and has established itself as a leading test management solution.

Architecture

Quality Center is built as an enterprise application using Java 2 Enterprise Edition (J2EE) technology. It supports both MS SQL Server and Oracle as backend databases. The architecture of Quality Center consists of three main components:

  1. Client: The client component is downloaded on the end user’s system when accessing Quality Center. It provides a user-friendly interface for interacting with the server and utilizes technologies like .NET and COM over a secure HTTPS connection.
  2. Application Server: The application server runs on platforms like Windows or Linux and handles client requests. It uses the Java Database Connectivity (JDBC) driver to communicate with the database server.
  3. Database Server: Quality Center stores information in three schemas within the database server. These include the Site Administration schema, the Lab Project schema, and the Project schema. Each schema stores specific information related to domains, users, site parameters, lab data, and project-related data.

Editions

HP distributes Quality Center/ALM in four different editions, each catering to specific needs and requirements:

  1. HP ALM: This edition offers the most comprehensive set of features and functionalities, including requirements management, test management, defect management, and integration with other HP products like UFT and Load Runner.
  2. HP ALM Essentials: Designed for organizations seeking basic features, this edition focuses on requirements management, test management, and defect management.
  3. HP Quality Center Enterprise Edition: This edition is tailored for organizations that primarily use Quality Center for testing purposes. It includes features for test management and integrates with Unified Functional Tester (UFT).
  4. HP ALM Performance Center Edition: This edition is ideal for organizations that want to utilize Quality Center for performance testing using HP Load Runner. It supports performance test management and execution.

Workflow

Quality Center follows a structured workflow that encompasses various stages of the testing process:

  1. Planning: In this stage, project milestones, deliverables, and resources are defined. The scope of each release is determined, and requirements specifications are drafted.
  2. Test Design: Based on the defined requirements, test plans and test cases are created. Testers outline the steps, expected results, and any necessary test data.
  3. Test Execution: Testers execute the test cases, either manually or through automation. The results are recorded and tracked within Quality Center.
  4. Defect Tracking: If any defects are identified during the test execution phase, they are logged in Quality Center, and the necessary information is provided for developers to reproduce and fix the issues.
  5. Reporting and Metrics: Throughout the testing process, Quality Center generates reports and metrics to analyze test coverage, defect trends, and overall project progress. These insights aid in making data-driven decisions and identifying areas for improvement.

In summary, Quality Center is a comprehensive test management tool that offers advanced functionalities for test planning, execution, and tracking. Its robust project management capabilities, flexible architecture, and different editions cater to diverse organizational needs. By implementing Quality Center in their testing processes, organizations can enhance collaboration, improve efficiency, and ensure the delivery of high-quality software products.
