# Required Verification steps - Cheap steps, do after finishing a modification task: - typecheck of modified packages - prettier of modified files - After every bigger step: - lint of modified packages - Unit tests of modified packages - After reaching a milestone or finishing plan implementation: - if GUI part was changed, run playwright integration tests from app/gui - always, regardless of what was changed: electron package tests from app/electron-client, including AI tests. # How to run Electron Package tests Run `git submodule update --init --recursive` before the build. Without it `--mode staging` silently falls back to defaults and the resulting binary fails the very first e2e step (login screen never renders, console shows `Failed to fetch`). The ide build should be with staging environment by default (`--mode staging` option in case of `./run ide build` script). The credentials file should be provided by user. If working on a worktree, try to copy it from main repo.
