Build a comprehensive QA testing system for a well-known Japanese e-commerce platform


Our client is a leading Japanese SaaS-based eCommerce platform empowering businesses of all sizes with user-friendly tools to build and manage successful online stores. Their comprehensive offering, including intuitive CMS, extensive product management features, and diverse payment/shipping options, simplifies entry and success in the eCommerce landscape.

Business challenges

As the platform grew in functionality and complexity, the internal engineering team struggled to keep pace with testing, leading to quality concerns. Recognizing this, the client sought outsourced software testing with test automation to:

  • Access seasoned testers: Leverage expertise in handling complex systems.
  • Improve testing efficiency: Reduce cost and time to market for new features.
  • Enhance quality assurance: Secure a robust platform for customers’ business-critical operations.

Customer requirements

The company carefully selected an outsourcing partner with a proven track record in software testing. The partner helped the company to implement a comprehensive testing strategy that included manual and automated testing. Test automation would help reduce the cost and time of testing and improve testing quality.

  • Extremely high quality required: We require comprehensive testing of our e-commerce system, which is critical to customers’ business and involves payments.
  • Efficient testing: We want testing to be as efficient as possible to reduce costs and time when releasing a new feature.
  • Automated regression testing: We want regression tests to be automated to detect regressions in our frequently updated system quickly.
  • Specification review: We want to review our specifications to identify errors or omissions.
  • Flexible test team: We want to be able to flexibly adjust the size of our test team based on development needs and the amount of testing required.
  • Japanese-speaking test engineer: We want to assign a test engineer who can communicate directly in Japanese to improve communication accuracy and speed.
