This class provides the main methods used to execute tests and checkpoints.

Eyes method​

Syntax​

let eyes = new Eyes(runner);
let eyes = new Eyes();

Parameters​

runner

Type: EyesRunner [Optional ]

If this parameter is provided, it must be an instance of either the ClassicRunner or VisualGridRunner classes. If a VisualGridRunner is passed then the image will be rendered using the Ultrafast Grid. If this parameter is not provided, then DOM rendering is done using the local browser defined by the driver parameter passed to the Eyes.open method.

Return value​

Type: Eyes

Use the object returned to call the various methods provided by the Eyes class.

abort method​

Syntax​

let result = await eyes.abort();

Parameters​

This method does not take any parameters.

Return value​

Type: Promise<TestResults>

Remarks​

If you call this method on a test that was opened but not closed, then then test will have an aborted status in the Eyes Test Manager. If you call it after the test has been successfully closed, then the call is ignored.

addProperty method​

Syntax​

let value = eyes.addProperty(name, value);

Parameters​

name

Type: string

The name of the property.

value

Type: string

The value associated with the name.

Return value​

Type: Configuration

Remarks​

  • Set multiple properties by calling Eyes.addProperty or Configuration.addProperty multiple times with the same property name and with different values.
  • You should not assign a given value to a property more than once in a given test run.
  • You can also associate properties with a batch using BatchInfo.addProperty.

check method​

Syntax​

let result = await eyes.check(name, checkSettings_obj);

let result = await eyes.check(checkSettings_lit);

let result = await eyes.check();

Parameters​

name

Type: string

The tag defines a name for the checkpoint in the Eyes Test Manager. The name may be any string and serves to identify the step to the user in the Test manager. You may change the tag value without impacting testing in any way since Eyes does not use the tag to identify the baseline step that corresponds to the checkpoint - Eyes matches steps based on their content and position in the sequences of images of the test. See How Eyes compares checkpoints and baseline images for details.

checkSettings_obj

Type: CheckSettings

The fluent API calls, starting with one of the Target methods.

A series of method calls to the CheckSettings class, in Fluent API style.

Declaration​

<TLocator extends string>(settings:VisualLocatorSettings<TLocator>):Promise<Record<TLocator,RegionPlain[]>>

Parameters​

settings

Type: VisualLocatorSettings<TLocator>

A literal object that defines the required visual locator names and whethere a single or all instances of each locator should be found. See the example below for more details.

Return value​

Type: Promise<Record<TLocator,RegionPlain[]>>

Returns a mapping between the names passed in the locatornames field passed as a parameter and the regions in the viewport where the graphic images defined by those locator names were detected. If the firstOnly parameter is passed and has a value of true then only the 1st result found is retuned.

If the image of a particular locator name is not found in the viewport, the locator is mapped to a zero length array. If a locator name is passed, and a locator of that name has not been defined on the Eyes server, the returned locator will be mapped to a value of null instead of an array.

Type definitions​

RegionPlain

Used to describe a position and rectangular region in an image. RegionPlain is defined as: LocationPlain&RectangleSizePlain

Remarks​

The article Visual locators describes in detail how to associate locator names with graphic images and how to search for instances of the graphic in the browser viewport. The example below is a briefer description of how to search for instances of the locator graphics.

open method​

Syntax​

let result = await eyes.open(driver);

let result = await eyes.open(driver, appName, testName, viewportSize);

let result = await eyes.open(driver, appName, testName);

let result = await eyes.open(driver, appName);

Parameters​

driver

Type: Page

The web driver.

appName

Type: string [Optional ]

The application name. This may be any string. You can set the application name for all tests using the Configuration.setAppName method or Eyes.setAppName method. If you do so, then set this parameter to a value of null to indicate that the configuration default should be used.

testName

Type: string [Optional ]

The name of the test. This name must be unique within the scope of the application name. It may be any string.

viewportSize

Type: RectangleSizePlain [Optional ]

The size of the viewport

The size of the viewport passed as an object.

The size of the viewport passed as an object {'width':, 'height':}

Defines the viewport size of the browser that will be set before the start of the test. If this parameter is not provided then the viewport size will be based on the current browser window size. See Using viewports in Eyes for more details.

Return value​

Type: Promise<Page>

The returned web driver is a clone of the driver passed as a parameter. It is recommended that you use the web driver object returned by this method in all further calls to the web driver. This allows Eyes to record these interactions and play them back in the Eyes Test Manager.

Remarks​

After making a call to this method, you must eventually terminate the test by calling Eyes.close (in case of a normal completion) or Eyes.abort (in case of an aborted test). If you want to run another test, then it is recommended to do this with a newly created Eyes instance to avoid side effects. However, in principle, it is legal to call Eyes.Open again to start a new test on the same Eyes instance.

setApiKey method​

Syntax​

eyes.setApiKey(apiKey);

Parameters​

apiKey

Type: string

Your API key.

Return value​

Type: void

Remarks​

Set this immediately after the Eyes object is created (before calling open). If you have an environment variable called APPLITOOLS_API_KEY that is set to the value of your API key, then you do not need to call this method, and Eyes will take the string from the environment value.

setAppName method​

Syntax​

eyes.setAppName(appName);

Parameters​

appName

Type: string

The application name. This may be any string.

Return value​

Type: void

Remarks​

If you call this method, it must be called before the call to Eyes.open. In the call to Eyes.open, if you provide the application parameter, then it will override the value set here. If you don't provide the parameter or pass a null, then the value set here will be used.

All tests that have the same batch ID will appear in the Test results in the same batch. If the value is a falsy value or is not passed and the environment variable APPLITOOLS_BATCH_ID is defined, then the value of the environment variable will be used as the ID. Otherwise, an internal id will be generated.

  • Create an Eyes instance.
  • Call the Eyes.setConfiguration method with the configuration object.
  • Call the Eyes.open method to start the test session.

Once you've changed the configuration of an Eyes instance by calling Eyes.setConfiguration or by setting a configuration directly on the Eyes instance, if you want to change the configuration, you must use the following sequence:

  • Get the current configuration using Eyes.getConfiguration to a local variable.
  • Make changes to the local configuration value.
