Valtes Co., Ltd. (Headquarters: Nishi-ku, Osaka; Chiyoda-ku, Tokyo; Representative Director and President: Koichi Tanabe; hereinafter, Valtes), a group company of Valtes Holdings Co., Ltd. that provides software testing and quality improvement support, has newly added a function to support test design in scenario testing to its in-house AI test design tool "TestScape" to further promote standardization and quality stabilization in test design operations.
In scenario testing, there is a challenge that the design content tends to be influenced by the experience and knowledge of the person in charge, as it requires business understanding, user perspective, and judgment of coverage. With this new function, it becomes possible to proceed with test design while visualizing the design process and the basis for judgment, which will lead to improved internal review efficiency, reduced individual dependency, and stabilized design quality.
■ Background
While test design in software development is a critical process that affects quality, test design during scenario testing is highly difficult and tends to depend on the person in charge.
Scenario testing is a testing method that verifies whether objectives can be achieved based on user operations and business flows. In addition to the absence of a single correct answer, it requires business understanding, user perspective, and judgment of coverage (scope and depth of testing), which can lead to differences in viewpoints and importance judgments depending on the test designer's experience and knowledge, resulting in variations in design quality and individual dependency. Furthermore, insufficient sharing and accumulation of design processes and rationales can lead to increased review burden and unstable quality.
To address these challenges, Valtes developed this function with the aim of realizing an environment where scenario tests can be designed efficiently and with clear rationale, regardless of experience or skill.
■ About TestScape
"TestScape" is a test design support tool based on generative AI, which has learned the test design knowledge accumulated by Valtes, and "QUINTEE," a uniquely constructed testing framework.

By visualizing the design process as intermediate deliverables (documents), it supports the realization of explainable test design based on clear rationale. "TestScape" is currently operated for internal use.
■ Supported Content for Test Design in Scenario Testing
With this update, "TestScape" can incrementally proceed with test design based on input materials such as business manuals and specifications.
Scenario tests are designed according to the following process:
① Flowchart creation (AI generation supported)
② Basic scenario creation (AI generation supported)
③ Pattern creation
④ Test case creation
AI supports the creation of flowcharts and basic scenarios, leading to pattern creation and test case creation.
This makes it possible to proceed with test design while visualizing the process, clarifying the rationale for "why that test is necessary" and improving explainability.
■ Expected Effects
Utilizing "TestScape," including this update, is expected to bring the following effects to test design operations:
・Broader application in test design operations
・Efficiency improvement in test design man-hours
・Stabilization of quality through standardization of design processes
・Improved review efficiency through visualization of design rationale
・Establishment of a design process less dependent on the experience of the person in charge
Furthermore, internal verification by Valtes has confirmed the possibility of reducing test design man-hours by approximately 40% compared to conventional methods. By accumulating design processes and rationales, it also contributes to the reuse of test assets and continuous quality improvement.
■ Future Developments
Valtes will continue to combine the "QUINTEE"-based test design process with AI, and promote the realization of explainable test design through the development of "AI Test Design Consultants" who will be responsible for proposing and executing test designs utilizing generative AI test tools.
