While someone tests Toss, we build the way to test
Key point
The Toss QA Platform team introduces Tossion, its in-house QA platform built to maintain quality amid weekly large-scale deployments with recurring changes.
Details
Toss carries out large-scale deployments with hundreds of code changes occurring every week, and to support this, the Toss QA Platform team goes beyond simple testing to establish the standard for quality.
Each week, when a Release Candidate is uploaded, the team performs a Smoke Test via Toss Doctor and a Regression Test using Toss Checker. After release, the team also monitors Crash metrics to decide whether a Hotfix response is needed.
To overcome the limitations of commercial tools, the team built its own in-house QA platform, Tossion, which includes the following core tools.
- PRCheck: a PR analyzer that analyzes the scope of impact of changes and suggests test priorities
- tcgen: a tool that automatically generates Test Cases based on PRD and design documents
- Toss Butler: an in-house tool management bot that consolidates various previously scattered bots
- Crash Trend & Hotfix Dashboard: a dashboard for analyzing crash trends and preventing recurrence
Toss aims to use AI to expand the scope of test automation and create an environment where people can focus on finding truly critical defects.
