content method

Syntax

eyes.check(Target.window().content());

Parameters

This method does not take any parameters.

Return value

Type: CheckSettings

The value returned is the object that called the method. You can use it to call other methods supported by the object class.

Remarks

You can call this method in two ways - with parameters and without parameters. The meaning of the method, and the way it can be used is different in each case. When the method is called without parameters it sets the default match level for this target. When called with one or more regions as parameters it defines the match level for that region. The sections below provide some more details regarding how to use this method in each of these modes.

Called without parameters

If this method is called without parameters then it sets the default match level for this target. This overrides the hard-coded default and the default match level defined by using setMatchLevel.

For a given target you may call only one of the following methods (without parameters) that set a target default match level:

• matchLevel
• strict
• content
• layout
• exact

Called with parameters

When the method is called with one or more parameters that define one or more regions, then these set the match level for those regions, overiding the defaults set for the target (by calling these methods without a parameter), set by setMatchLevel and the hardcoded default match level.

You may define multiple regions that have an explicit match level by calling this method multiple times in a chain, or by passing the method multiple regions.

The region matchlevel methods strict(regions), layout(regions), content(regions), strictRegions(regions), layoutRegions(regions), and contentRegions(regions) should not overlap each other or the regions defined using checksettings.ignore (regions) or ignoreRegions(regions). If they overlap with each other, or regions that were defined using the Test Manager, then the results are undefined.

contentRegions method

Syntax

eyes.check(Target.window().contentRegions(regions));

Parameters

Return value

Type: CheckSettings

The value returned is the object that called the method. You can use it to call other methods supported by the object class.

Remarks

You can define multiple regions that have an explicit match level by calling this method multiple times, or by passing the method multiple regions.

The region matchlevel methods strict(regions), layout(regions), content(regions), strictRegions(regions), layoutRegions(regions), and contentRegions(regions) should not overlap each other or the regions defined using checksettings.ignore (regions) or ignoreRegions(regions). If they overlap with each other, or regions that were defined using the Test Manager, then the results are undefined.

The value returned is the object that called the method. You can use it to call other methods supported by the object class.

Remarks

This method sets the default match level for this target. This overrides the hard-coded default and the default match level defined by using setMatchLevel.

For a given target you may call only one of the following methods that set a target default match level:

• matchLevel
• strict
• content
• layout
• exact

To set a match level for a one or more regions within a target use one of the following methods:

layoutBreakpoints method

Syntax

eyes.check(Target.window().layoutBreakpoints(layoutBreakpoints_bool));
eyes.check(Target.window().layoutBreakpoints());
eyes.check(Target.window().layoutBreakpoints(layoutBreakpoints_arr));

Parameters

layoutBreakpoints_bool

Type: boolean [Optional ]

You can either pass a boolean value or a number. Pass a value of true to enable this feature. Pass one or more viewport widths explicitly, and the JavaScript is executed and the DOM is extracted for each viewport width. For each target, the Ultrafast Grid uses the DOM extracted with the widest viewport that is smaller than the viewport width. For example, if the values 640, 768 and 1024 are passed, then targets with a width between 640 and 767 (inclusive) use the DOM extracted at 640. Similarly, targets between 768 and 1023 use the DOM extracted at 768. Targets that have a width smaller than the smallest defined width use a DOM extracted at one less than the smallest DOM width (639 in this example). Targets that have a width larger than the largest width defined (1024 in this example) use the DOM extracted at the largest width. If no width is specified, then a separate DOM is extracted for each distinct execution environment viewport width.

layoutBreakpoints_arr

Type: number[] [Optional ]

You can either pass a boolean value or a number. Pass a value of true to enable this feature. Pass one or more viewport widths explicitly, and the JavaScript is executed and the DOM is extracted for each viewport width. For each target, the Ultrafast Grid uses the DOM extracted with the widest viewport that is smaller than the viewport width. For example, if the values 640, 768 and 1024 are passed, then targets with a width between 640 and 767 (inclusive) use the DOM extracted at 640. Similarly, targets between 768 and 1023 use the DOM extracted at 768. Targets that have a width smaller than the smallest defined width use a DOM extracted at one less than the smallest DOM width (639 in this example). Targets that have a width larger than the largest width defined (1024 in this example) use the DOM extracted at the largest width. If no width is specified, then a separate DOM is extracted for each distinct execution environment viewport width.

Remarks

The following configuration key/value pairs are currently supported:

'chromeHeadless'

Normally, the Ultrafast Grid renders its images using Headless Chrome. There are cases where the behavior of Headless Chrome is different from that of regular Chrome browser, and if the baseline was created with a regular Chrome browser, the differences will be found. Set this option to a value of false to instruct the Ultrafast Grid to use a regular Chrome browser instead of the Headless Chrome browser, so as to eliminate differences that arise because of the different types of Chrome browser.

'polyfillAdoptedStyleSheets'

Adopted Stylesheets are a way to create and distribute reusable styles when using a Shadow DOM. Adopted Stylesheets are not supported by all browsers, so their use may cause mismatches when doing cross-browser validation. By default, when the Ultrafast Grid detects that a page being checked uses Adopted Stylesheets, it will not render that checkpoint, the check will fail, and the test will be aborted. In the Test Manager, the test results for that run will have an Aborted status, and the step that failed will have a Missing status.

To enable rendering of checkpoints that include Adopted Stylesheets, and to ensure that the test can complete successfully, you need to explicitly set the Ultrafast Grid option polyfillAdoptedStyleSheets to a value of true or false:

• Setting a value of true instructs the Ultrafast Grid to polyfill Adopted Stylesheets.
• Setting a value of false instructs the Ultrafast Grid to render the page without polyfilling Adopted Stylesheets.

You can set this option globally using the method Configuration.setVisualGridOption

You can override the global value for a given checkpoint using the method CheckSettings.visualGridOption.

Example

JavaScript

eyes.check(
        Target.window()
                .visualGridOptions(new VisualGridOption("polyfillAdoptedStyleSheets", true)));

withName method

Syntax

eyes.check(Target.window().withName(name));

Parameters

name

Type: string

The name to be given to this check point.

Return value

Type: CheckSettings

The value returned is the object that called the method. You can use it to call other methods supported by the object class.

Remarks

You can only call this method once in a given chain.
