Checkpoints

Checkpoints are verification points that KaneAI evaluates during test execution. They let you assert conditions, branch on results, or extract values for later use.

Checkpoint Types

Type	What it does
Assertion	Verify a condition is true — fails the test if not
If/Else	Branch execution based on a condition
Extraction	Store a value for use in later steps

All three types work with every analyze method below.

Analyze Methods

Each checkpoint uses an analyze method to determine where to look for the data:

Method	Data Source	When to Use
Visual	Screenshot (what you see on screen)	Text, labels, prices, counts, colors, visibility checks
Textual (DOM)	Page DOM elements	Element states (disabled, checked), CSS properties, HTML attributes
URL	Browser URL bar	URL path, query params, redirects
Title	Page title	Document title verification
DevTools	Browser internals	Network traffic, console logs, performance, cookies, localStorage

How to Use

Write your assertions naturally in the objective. KaneAI automatically picks the right analyze method:

Assert: the price is $29.99                    → Visual
Assert: the submit button is disabled          → Textual (DOM)
Assert: URL contains /checkout                 → URL
Assert: page title contains "Dashboard"        → Title
Assert: no API calls returned 5xx              → DevTools (Network)
Assert: no console errors                      → DevTools (Console)
Assert: page LCP is under 2500ms               → DevTools (Performance)
Assert: session cookie exists                  → DevTools (Cookies)
Assert: auth_token exists in localStorage      → DevTools (localStorage)

Extractions work the same way:

Store the product price                        → Visual
Store the current URL                          → URL
Store all cookies                              → DevTools (Cookies)
Store the API response body                    → DevTools (Network)

Operators

Assertions support these comparison operators:

Operator	Meaning	Example
`equals`	Exact match	price equals "29.99"
`contains`	Substring match	URL contains "/checkout"
`not_contains`	Does not contain	title not contains "Error"
`gt` / `gte`	Greater than / or equal	items greater than 5
`lt` / `lte`	Less than / or equal	LCP less than 2500
`not_equals`	Not equal	status not equals "failed"
