Epsilon added a shared service with natural-language test steps alongside its regression tests

only one source so far

Epsilon built a shared service for testing web interfaces for its product teams. Amazon Nova Act and Amazon Bedrock AgentCore Browser Tool allow steps to be specified in natural language and complement the existing Playwright regression tests.

Epsilon built a shared service for testing web interfaces in which product teams provide a target URL and a list of steps in natural language. The service uses Amazon Nova Act and Amazon Bedrock AgentCore Browser Tool. It complements the existing regression tests based on Playwright, which remain the foundation of testing.

The architecture includes a platform API, a service for running background jobs and integrated tools for controlling the browser. Jobs are queued in Amazon SQS and run in Amazon ECS. Results, screenshots, execution logs and HTML reports are stored in Amazon S3. According to the case study on AWS Machine Learning Blog, Amazon Bedrock AgentCore Browser Tool handles browser infrastructure and session lifecycle management.

The example workflow includes logging in, filling out a form, scrolling the page and verifying the outcome. It also includes conditional steps, such as skipping a walkthrough if it appears or scrolling the page until the desired field is visible. Participating teams create and run tests through the same interface as other platform features. Details are available in the source article.

What changed

Why it matters

The case study offers a concrete architecture for teams that want to test workflows with conditional steps described in everyday language alongside their regression tests. It shows how browser control, a job queue and result storage fit together; however, it does not in itself demonstrate general time savings or greater test reliability.

Two audiences, two different impacts

What this means

01

For individuals

Testers in participating teams at Epsilon can describe the desired workflow in natural language, including responses to conditionally displayed elements, and run it through the existing platform API.

What to do When preparing a similar test, explicitly describe the conditional steps and the required verification of the outcome, as illustrated by the published workflow.

02

For a business

Epsilon consolidated the operation of this testing service into a shared platform. According to the case study, individual product teams therefore do not have to handle browser infrastructure, identity or model integration separately.

Development
What to decide When evaluating a similar service, check how to integrate team permissions, a queue of test jobs and result storage into the existing platform.
