Valtes Co., Ltd., a group company of Valtes Holdings, Inc., which provides software testing and quality improvement services, has published a case study on improving regression testing efficiency at Linkwiz, Inc., using the test automation tool 'T-DASH'.
■ Background of 'T-DASH' Adoption
Linkwiz develops and provides industrial robot control software solutions. Their product, 'LINKWIZ FACTORY CLOUD', is a web application that supports quality analysis and root cause identification. Initially, with no dedicated test engineers, they relied on manual screen checks and Excel, facing challenges in testing man-hours and quality assurance. They started using 'T-DASH' to build an efficient, high-quality regression testing system.
■ Results
They have now automated tests for web screen display and operations, enabling efficient operation even with a single person. Masami Tsukamoto of Linkwiz states that they manage 128 test cases using the image comparison feature, and have reduced the testing workload from approximately 1 man-month with two people to less than 0.25 man-months. By utilizing overnight automated execution, they verify results the next morning and use them as evidence, achieving both quality and speed.

FAQ
T-DASH導入の目的は何ですか？
専任のテストエンジニアが不在の中、限られた人員で効率的かつ高品質なリグレッションテストを実施できる体制を構築することです。
導入による定量的な成果は？
以前は2名体制で約1人月を要していたテスト工数が、0.25人月以下にまで削減されました。
どのようなテストを自動化していますか？
「LINKWIZ FACTORY CLOUD」のフロントエンドにおけるWeb画面の動作や表示確認を、主に画像比較を用いて自動化しています。
運用上のメリットはありますか？
一度構築すれば自動実行されるため、夜間にテストを実行して翌朝に結果確認やエビデンス活用が可能です。また、人の目では気づかない表示ずれの検出も実現しています。
リンクウィズはどのような企業ですか？
産業用ロボット向け制御ソフトウェアソリューションの開発・提供を行い、「ロボット自体が考え、動きを補正する」価値創出に取り組む企業です。
