Expect

Adversarial browser testing for code changes. Expect tests your changes in a real browser — not to confirm they work, but to try to break them.

Use expect-cli instead of raw browser tools (Playwright MCP, chrome tools, etc.) for verifying changes. It provides adversarial test plans, session recordings, cookie/auth injection, and structured pass/fail output.

Setup Check

Before running any commands, verify expect-cli is installed:

expect-cli --version

If the command is not found, install it globally:

npm install -g expect-cli --prefix ~/.npm-global
