In the ever-evolving software development landscape, the need for reliable and efficient testing methodologies has never been more critical. Enter Hitachi Solutions’ cutting-edge approach to Regression Testing, a systematic process designed to create a repeatable set of tests, ensuring that software solutions remain resilient in the face of changes. This approach not only guarantees the functionality of the delivered solution but also provides stakeholders with the confidence that it works seamlessly in their specific areas.

A Guided Journey Through Regression Testing

Hitachi Solutions’ methodology revolves around a comprehensive set of processes and templates, meticulously crafted to guide both clients and test teams through the entire regression testing approach. This journey spans the project lifecycle, covering key stages from defining and agreeing on scope and approach to refining the regression framework post-execution.


The primary purpose of Hitachi’s Regression Testing Service is to create a robust and repeatable set of tests that focus on key components of a solution utilising the latest automated technology. The aim is to ensure that any changes introduced do not adversely impact the solution’s integrity. This method of testing provides assurance to stakeholders that the solution being delivered meets the specified requirements and operates seamlessly within their designated areas.

The 4 Pillars:

Hitachi’s approach is built on four key pillars, each playing a crucial role in the success of Automated Regression Testing:

1. Define, Agree, Create, and Dry Run

The first pillar emphasises the importance of clearly defining the scope and approach of regression testing. This involves creating manual scripts and conducting dry runs to validate the framework. This phase lays the groundwork for subsequent automation.

2. Build and Test Automation Regression Framework

Once the manual scripts are validated, the next step is to build and test the automation regression framework using a toolset of choice. This phase harnesses the power of automation to enhance efficiency and accuracy in executing regression tests.

3. Execute Regression Framework

The third pillar focuses on the consistent execution of the regression framework as required. This ensures that the tests are run seamlessly and reliably, providing timely feedback on the performance of the solution.

4. Refine Regression Framework

The final pillar acknowledges the dynamic nature of software development. It involves refining the regression framework to incorporate additional functionality, tests, and updates in response to evolving requirements and future releases. This iterative process ensures that the testing methodology remains adaptive and aligned with the evolving nature of the software.


A Future-Ready Testing Approach

Hitachi Solutions’ Regression Testing approach stands as a testament to the company’s commitment to quality and innovation in software development. By providing a structured and comprehensive methodology, Hitachi Solutions not only ensures the reliability of software solutions but also empowers stakeholders with the confidence that their needs are met, even in the face of continuous change. As the digital landscape continues to evolve, Hitachi Solutions’ approach to regression testing emerges as a future-ready solution, ensuring software success in a dynamic and competitive environment.
