I added a new option to the screenshot method to customize the color of
the box when we want to mask some elements for the screenshot.
The default color is pink `#FF00FF`, but with this new option you can
specify the color you like the most, like a nice green `#00FF00`:
```js
await page.screenshot({
mask: [page.locator('div').nth(5)],
maskColor: "#00FF00",
})
```

For security purpose, we would like to restrain sending HTTP credentials
to only the specified server. The idea is to give the ability to specify
a origin (scheme://host:port) additionally to current pair
username/password. When an authorization response is received from
servers, the credentials are sent only if the server origin in the
request matches case insensitive the specified origin.
This reverts commit 303c5998f8.
Reason for revert: I tried enabling `ssim-cie94` by default on
ionic-framework test suite, and it proves to be overly strict for their
usecase.
The option defines a comparator to be used to compare images.
Possible values are `"pixelmatch"` and `"ssim-cie94"`.
Note: This reverts commit 8167f8bf54.
- Replace links to `selectors.md` with `locators.md`.
- Remove sections that are covered by Locators docs.
- Restructure the rest of selectors doc, update them in terms of
locators.
Fixes#18992.
This patch implements a new image comparison function, codenamed
"ssim-cie94". The goal of the new comparison function is to cancel out
browser non-determenistic rendering.
To use the new comparison function:
```ts
await expect(page).toHaveScreenshot({
comparator: 'ssim-cie94',
});
```
As of Nov 30, 2022, we identified the following sources of
non-determenistic rendering for Chromium:
- Anti-aliasing for certain shapes might be different due to the
way skia rasterizes certain shapes.
- Color blending might be different on `x86` and `aarch64`
architectures.
The new function employs a few heuristics to fight these
differences.
Consider two non-equal image pixels `(r1, g1, b1)` and `(r2, g2, b2)`:
1. If the [CIE94] metric is less then 1.0, then we consider these pixels
**EQUAL**. (The value `1.0` is the [just-noticeable difference] for
[CIE94].). Otherwise, proceed to next step.
1. If all the 8 neighbors of the first pixel match its color, or
if the 8 neighbors of the second pixel match its color, then these
pixels are **DIFFERENT**. (In case of anti-aliasing, some of the
direct neighbors have to be blended up or down.) Otherwise, proceed
to next step.
1. If SSIM in some locality around the different pixels is more than
0.99, then consider this pixels to be **EQUAL**. Otherwise, mark them
as **DIFFERENT**. (Local SSIM for anti-aliased pixels turns out to be
very close to 1.0).

Following the `getByText()` and other methods:
- By default, matching is substring and case-insensitive. Before, it was
only case-insensitive, but not substring.
- With new option `exact: true`, matching is full string and
case-sensitive.
- Matching always normalizes whitespace.
- Codegen generates `exact: false` by default.
- `internal:role` treats `[name="foo"i]` as non-exact match.
Various fixes:
- Updated `getByRole` docs to match the reality.
- Locator generator edge cases.
This patch:
- updates documentation to lead users from `TestConfig.snapshotDir` and
`testInfo.snapshotSuffix` to `TestConfig.snapshotPathTemplate` as a
better and more flexible alternative.
- drops `{snapshotSuffix}` from documentation
- stops using `snapshotSuffix = ''` in our own tests and switches us
to the `snapshotPathTemplate`.
- adds `{testName}` token.
This configuration option allows to set a string with template
values for precise control over snapshot path location.
An example of `snapshotPathTemplate` usage:
```ts
// playwright.config.ts
// Notice the `testDir` configuration!
export default {
testDir: './tests',
snapshotPathTemplate: './__screenshots__/{platform}/{projectName}/{testFilePath}/{arg}{ext}',
}
```
Currently supported "magic tokens" inside the `snapshotPathTemplate`
are:
- `{testDir}` - project's `testDir`
- `{snapshotDir}` - project's `snapshotDir`
- `{platform}` - `process.platform`
- `{projectName}` - Project's sanitized name
- `{testFileDir}` - Directories in relative path from `testDir` to test
file path (e.g. `page/` in the example below)
- `{testFileName}` - Test file name (with extension) (e.g.
`page-click.spec.ts` in the example below)
- `{testFilePath}` - Relative path from `testDir` to test file path
(e.g. `page/page-click.spec.ts` in the example below)
- `{ext}` - snapshot extension (with dots)
- `{arg}` - joined snapshot name parts, without extension (e.g.
`foo/bar/baz` in the example below)
- `{snapshotSuffix}` - `testInfo.snapshotSuffix` value.
Consider the following file structure:
```
playwright.config.ts
tests/
└── page/
└── page-click.spec.ts
```
The following `page-click.spec.ts`:
```ts
// page-click.spec.ts
import { test, expect } from '@playwright/test';
test('should work', async ({ page }) => {
await expect(page).toHaveScreenshot(['foo', 'bar', 'baz.png']);
});
```
Fixes#7792
