# Checkpoints

> Checkpoints are verification points KaneAI evaluates during test execution: assert conditions, branch on results, or extract values for later use.

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](/docs/docs/kane-cli-checkpoint-visual/)         | Screenshot (what you see on screen) | Text, labels, prices, counts, colors, visibility checks                      |
| [Textual (DOM)](/docs/docs/kane-cli-checkpoint-textual/) | Page DOM elements                   | Element states (disabled, checked), CSS properties, HTML attributes          |
| [URL](/docs/docs/kane-cli-checkpoint-url/)               | Browser URL bar                     | URL path, query params, redirects                                            |
| [Title](/docs/docs/kane-cli-checkpoint-title/)           | Page title                          | Document title verification                                                  |
| [DevTools](/docs/docs/kane-cli-checkpoint-devtools/)     | Browser internals                   | Network traffic, console logs, performance, cookies, localStorage, clipboard |

## 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)
Assert: the clipboard has the copied link      → DevTools (Clipboard)
```

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" |
