Method Options

Methods options are the options that can be set per method. If the option has the same key as an option that has been set during the instantiation of the plugin, this method option will override the plugin option value.

Save Options

`disableBlinkingCursor`

Type: boolean
Mandatory: No
Default: false
Supported: Web, Hybrid App (Webview)

En/Disable all input, textarea, [contenteditable] caret "blinking" in the application. If set to true the caret will be set to transparent before taking a screenshot and reset when done

`disableCSSAnimation`

Type: boolean
Mandatory: No
Default: false
Supported: Web, Hybrid App (Webview)

En/Disable all CSS animations in the application. If set to true all animations will be disabled before taking a screenshot and reset when done

`enableLayoutTesting`

Type: boolean
Mandatory: No
Default: false
Used with: All methods
Supported: Web

This will hide all text on a page so only the layout will be used for comparison. Hiding will be done by adding the style 'color': 'transparent !important' to each element.

For the output see Test Output

தகவல்

By using this flag each element that contains text (so not only p, h1, h2, h3, h4, h5, h6, span, a, li, but also div|button|..) will get this property. There is no option to tailor this.

`hideScrollBars`

Type: boolean
Mandatory: No
Default: true
Used with: All methods
Supported: Web, Hybrid App (Webview)

Hide scrollbar(s) in the application. If set to true all scrollbar(s) will be disabled before taking a screenshot. This is set to default true to prevent extra issues.

`hideElements`

Type: array
Mandatory: no
Used with: All methods
Supported: Web, Hybrid App (Webview), Native App

This method can hide 1 or multiple elements by adding the property visibility: hidden to them by providing an array of elements.

`removeElements`

Type: array
Mandatory: no
Used with: All methods
Supported: Web, Hybrid App (Webview), Native App

This method can remove 1 or multiple elements by adding the property display: none to them by providing an array of elements.

`resizeDimensions`

Type: object
Mandatory: no
Default: { top: 0, right: 0, bottom: 0, left: 0}
Used with: Only for saveElement or checkElement
Supported: Web, Hybrid App (Webview), Native App

An object that needs to hold a top, right, bottom and left amount of pixels that need to make the element cutout bigger.

`fullPageScrollTimeout`

Type: number
Mandatory: No
Default: 1500
Used with: Only for saveFullPageScreen or saveTabbablePage
Supported: Web

The timeout in milliseconds to wait after a scroll. This might help identify pages with lazy loading.

`hideAfterFirstScroll`

Type: array
Mandatory: no
Used with: Only for saveFullPageScreen or saveTabbablePage
Supported: Web

This method will hide one or multiple elements by adding the property visibility: hidden to them by providing an array of elements. This will be handy when a page for example holds sticky elements that will scroll with the page if the page is scrolled but will give an annoying effect when a full-page screenshot is made

`waitForFontsLoaded`

Type: boolean
Mandatory: No
Default: true
Used with: All methods
Supported: Web, Hybrid App (Webview)

Fonts, including third-party fonts, can be loaded synchronously or asynchronously. Asynchronous loading means that fonts might load after WebdriverIO determines that a page has fully loaded. To prevent font rendering issues, this module, by default, will wait for all fonts to be loaded before taking a screenshot.

Compare (Check) Options

Compare options are options that influence the way the comparison, by ResembleJS is being executed.

NOTE

All options from the Save Options can be used for the Compare methods
All compare options can be used during service instantiation or for every single check method. If a method option has the same key as an option that has been set during the instantiation of the service, then the method compare option will override the service compare option value.
All options can be used for:
- Web
- Hybrid App
- Native App

`ignoreAlpha`

Type: boolean
Default: false
Mandatory: no

Compare images and discard alpha.

`blockOutSideBar`

Type: boolean
Default: true
Mandatory: no
Remark: Can only be used for checkScreen(). This is iPad only

Automatically block out the sidebar for iPads in landscape mode during comparisons. This prevents failures on the tab/private/bookmark native component.

`blockOutStatusBar`

Type: boolean
Default: true
Mandatory: no
Remark: This is Mobile only

Automatically block out the status and address bar during comparisons. This prevents failures on time, wifi or battery status.

`blockOutToolBar`

Type: boolean
Default: true
Mandatory: no
Remark: This is Mobile only

Automatically block out the toolbar.

`ignoreAntialiasing`

Type: boolean
Default: false
Mandatory: no

Compare images and discard anti-aliasing.

`ignoreColors`

Type: boolean
Default: false
Mandatory: no

Even though the images are in color, the comparison will compare 2 black/white images

`ignoreLess`

Type: boolean
Default: false
Mandatory: no

Compare images and compare with red = 16, green = 16, blue = 16, alpha = 16, minBrightness=16, maxBrightness=240

`ignoreNothing`

Type: boolean
Default: false
Mandatory: no

Compare images and compare with red = 0, green = 0, blue = 0, alpha = 0, minBrightness=0, maxBrightness=255

`rawMisMatchPercentage`

Type: boolean
Default: false
Mandatory: no

If true the return percentage will be like 0.12345678, default is 0.12

`returnAllCompareData`

Type: boolean
Default: false
Mandatory: no

This will return all compare data, not only the mismatch percentage

`saveAboveTolerance`

Type: number
Default: 0
Mandatory: no

Allowable value of misMatchPercentage that prevents saving images with differences

`largeImageThreshold`

Type: number
Default: 0
Mandatory: no

Comparing large images can lead to performance issues. When providing a number for the number of pixels here (higher than 0), the comparison algorithm skips pixels when the image width or height is larger than largeImageThreshold pixels.

`scaleImagesToSameSize`

Type: boolean
Default: false
Mandatory: no

Scales 2 images to the same size before execution of comparison. Highly recommended to enable ignoreAntialiasing and ignoreAlpha

Folder options

The baseline folder and screenshot folders(actual, diff) are options that can be set during the instantiation of the plugin or method. To set the folder options on a particular method, pass in folder options to the methods option object. This can be used for:

Web
Hybrid App
Native App

import path from 'node:path'

const methodOptions = {
    actualFolder: path.join(process.cwd(), 'customActual'),
    baselineFolder: path.join(process.cwd(), 'customBaseline'),
    diffFolder: path.join(process.cwd(), 'customDiff'),
}

// You can use this for all methods
await expect(
    await browser.checkFullPageScreen("checkFullPage", methodOptions)
).toEqual(0)

`actualFolder`

Type: string
Mandatory: no

Folder for the snapshot that has been captured in the test.

`baselineFolder`

Type: string
Mandatory: no

Folder for the baseline image that is being used to compare against.

`diffFolder`

Type: string
Mandatory: no

Folder for the image difference rendered by ResembleJS.
