Challenge: Limitations of the previously used automation tool

Although the company had been using a test automation tool for some time, several issues had become apparent, including functional limitations, cost concerns, and slow test execution. As the team looked ahead to further promoting in‑house development, improving the quality of the HR services offered to the market, and accelerating release cycles to support greater agility, they realized that their existing tool would be difficult to use effectively across the organization. This led them to begin building a new testing environment.

“While working to secure the talent needed for organizational growth and to develop our strategy, we faced the challenge of determining how we, as an agile development organization, would structure and scale our test automation environment,” recalls Yusuke Miura, Group Manager of the QA Group in the Product Development Office.

Selection factors: An environment where teams can experiment and fail safely

When evaluating new solutions, the team initially considered code‑based test frameworks. However, given internal conditions across the wider group and the need for future scalability, they began searching for a different option. With DevOps in mind, they were looking for a solution that would allow them to accelerate improvement processes — with the right balance of licensing flexibility, test accuracy, and test execution speed.

It was during this process that they discovered Tricentis Testim (“Testim”). “Around that time, the Japan office had just been established, and through public documentation and discussions, we realized the solution aligned well with our requirements,” says Saito. “Beyond the ability to run tests quickly with parallel execution, we were also attracted to the fact that Testim provides an environment where not only the QA team but also a wider range of users can try things out freely and even fail safely — something our previous tools, with their rigid constraints, didn’t allow.”

Key selection points

Outstanding speed through parallel execution
Easy‑to‑use UI/UX with low onboarding difficulty
Fast scenario creation through capture‑and‑replay
High flexibility and maintainability
Operational model that supports team‑level scaling

Test execution volume expands 6x, becoming an essential foundation for QA operations

Testim is now used as the test automation tool within the development process and has become a core platform that the QA team relies on in their daily work. Including not only the QA team but also development engineers, more than 30 members are now using Testim. As a result, compared with the previous tool, the following outcomes have been achieved.

Results:

Test execution volume increased by 600%
Before Testim, there were around 500 executions per month. With Testim, this has grown to more than 3,000 per month, with expectations to reach 5,000.
Test time reduced by 50%
Some test cases have been shortened to one‑fifth of their original duration.The reduction in manual rework risk, combined with time savings and efficiency gains, has also led to approximately 50% lower operational costs.
Regression testing automated, with over 90% coverage
Root‑cause analysis has become easier, and the test cycle and team workflows have improved as a result.

Expanding the use of Testim as the QA organization grows

As the company continues to expand its QA organization, it plans to further extend the use of Testim. As more of its services move toward in‑house development, the team aims to apply Testim’s UI‑based end‑to‑end testing to additional products. They also have high expectations for other Tricentis solutions, such as test management tools and performance testing.

Looking ahead to the future of the QA engineering organization, Kitamura explains:
“As long as we, as QA engineers, work within a business‑driven company like ours, it is important to think about quality from a business perspective. It’s not just about whether there are bugs in the code — if a user feels something is inconvenient or disadvantageous, that too should be considered a bug. We want to build an organization that focuses more on the value the product delivers to users. We expect Testim to support us in that direction.”
Since Testim significantly reduces workload, expectations for how it will help the team dedicate more time to quality are high.
