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

Using statement​

using Applitools.Selenium;

Methods​

Eyes method​

Syntax​

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

Parameters​

runner

Type: EyesRunner

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.

Open method​

Syntax​

IWebDriver outdriver = eyes.Open(driver);
IWebDriver outdriver = eyes.Open(driver, appName, testName, viewportSize);
IWebDriver outdriver = eyes.Open(driver, appName, testName);

Parameters​

driver

Type: IWebDriver

The web driver.

appName

Type: string

The application name. This may be any string. You can set the application name for all tests using the Configuration.SetAppName method or Eyes.AppName property. 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

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

viewportSize

Type: Size

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. For details, see Using viewports in Eyes.

Return value​

Type: IWebDriver

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.CloseAsync (in case of a normal completion) or Eyes.AbortAsync (in case of an aborted test). If you want to run another test, we recommend that you use 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.

Check method​

Syntax​

eyes.Check(checkSettings);
eyes.Check(name, checkSettings);

Parameters​

CheckSettings

Type: ICheckSettings

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

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 can 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. For details, see How Eyes compares checkpoints and baseline images.

CheckSettings

Type: ICheckSettings[]

One or more check settings, as an array or a comma separated list.

UseDom

This parameter enriches the Layout match level to include DOM information in the analysis. This parameter is only available if the match type is Layout. The default value is False.

Type: boolean

EnablePatterns

This parameter informs Layout to look for repeating patterns in the structure of the page, for example items shopping cart. Once a repeating structure is detected, it will be treated as a single unit and ignore the number of repetitions. Alerts are generated if there are changes such as irregularities or changes in the way internal items are aligned. This parameter requires useDom to be enabled. The default value is False.

Type: boolean

Example

eyes.Check(Target.Window().Fully().WithName("App page").EnablePatterns(True).UseDom(True));

Return value​

Type: void

Remarks​

For a detailed description of how to use this method see The Eyes SDK check Fluent API.

Close method​

Syntax​

TestResults result = eyes.Close(throwEx);
TestResults result = eyes.Close();

Parameters​

throwEx

Type: bool [Optional : default = true ]

If this parameter has a value of true, then if there are new, missing, or mismatched steps, an exception will be thrown. If the parameter is set to false, then an exception will not be thrown for the above cases. If the parameter is not passed, then it is as if a true value was passed.

Return value​

Type: TestResults

The result of the test can be obtained from the object returned. See TestResults class for a list of what information can be obtained from this object. See TestResults class for a list of what information can be obtained from this object.

Abort method​

Syntax​

TestResults value = eyes.Abort();

Parameters​

This method does not take any parameters.

Return value​

Type: 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.

AbortAsync method​

Syntax​

    eyes.AbortAsync();

Parameters​

This method does not take any parameters.

Return value​

Type: void

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.

AbortIfNotClosed method​

Syntax​

TestResults value = eyes.AbortIfNotClosed();

Parameters​

This method does not take any parameters.

Return value​

Type: 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​

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: void

Remarks​

  • 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.

CheckElement method​

Syntax​

eyes.CheckElement(selector, tag, matchTimeout);
eyes.CheckElement(selector, tag);
eyes.CheckElement(selector);

Parameters​

selector

Type: By

An object that defines a selector for the region.

tag

Type: string [Optional : default = null ]

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.

matchTimeout

Type: int [Optional : default = -1 ]

The retry time in milliseconds. If there is a mismatch, then Eyes will recapture and recheck the checkpoint until the timeout limit. This can help avoid mismatches in cases where the capture was done before the page was fully rendered. Passing a value of -1 will force the default timeout.

Return value​

Type: void

CheckFrame method​

Syntax​

eyes.CheckFrame(frameNameOrId, tag);
eyes.CheckFrame(frameNameOrId);

eyes.CheckFrame(frameIndex, matchTimeout);
eyes.CheckFrame(frameReference, matchTimeout, tag);
eyes.CheckFrame(frameReference, matchTimeout);
eyes.CheckFrame(framePath, matchTimeout, tag);
eyes.CheckFrame(framePath, matchTimeout);

Parameters​

frameNameOrId

Type: string

The name or id of the frame element.

tag

Type: string [Optional : default = null ]

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.

matchTimeout

Type: TimeSpan

The retry time in milliseconds. If there is a mismatch, then Eyes will recapture and recheck the checkpoint until the timeout limit. This can help avoid mismatches in cases where the capture was done before the page was fully rendered. Passing a value of -1 will force the default timeout.

frameIndex

Type: int

A Selenium frame index.

frameReference

Type: IWebElement

An object that references the frame.

framePath

Type: string[]

The path of the frame to check. This is a fully defined, top-down list of frame names or IDs, where each frame is nested in the previous frame.

Return value​

Type: void

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.

stitchContent

Type: bool

If the application window is larger than the viewport, and this parameter is true, then the entire page content is rendered. If this parameter is false, then only the viewport is rendered.

matchTimeout

Type: int [Optional : default = -1 ]

The retry time in milliseconds. If there is a mismatch, then Eyes will recapture and recheck the checkpoint until the timeout limit. This can help avoid mismatches in cases where the capture was done before the page was fully rendered. Passing a value of -1 will force the default timeout.

This parameter overrides any global timeout set using Eyes.MatchTimeout property or Configuration.SetMatchTimeout method.

matchTimeout

Type: TimeSpan

The retry time. The units are defined by the TimeSpan type. If there is a mismatch, then Eyes will recapture and recheck the checkpoint until the timeout limit. This can help avoid mismatches in cases where the capture was done before the page was fully rendered. Passing a value of -1 will force the default timeout.

This parameter overrides any global timeout set using Eyes.MatchTimeout property or Configuration.SetMatchTimeout method.

region

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.

fully

Type: bool? [Optional : default = null ]

Set to true to capture the full browser page and not just the viewport.

matchTimeout

Type: TimeSpan

The retry time in milliseconds. If there is a mismatch, then Eyes will recapture and recheck the checkpoint until the timeout limit. This can help avoid mismatches in cases where the capture was done before the page was fully rendered. Passing a value of -1 will force the default timeout.

Return value​

Type: void

ClearProperties method​

Syntax​

eyes.ClearProperties();

Parameters​

This method does not take any parameters.

Return value​

Type: void

GetConfiguration method​

Syntax​

Configuration value = eyes.GetConfiguration();

Parameters​

This method does not take any parameters.

Return value​

Type: Configuration

GetDriver method​

Syntax​

EyesWebDriver value = eyes.GetDriver();

Parameters​

This method does not take any parameters.

Return value​

Type: EyesWebDriver

SetConfiguration method​

Syntax​

eyes.SetConfiguration(configuration);

Parameters​

configuration

Type: IConfiguration

A configuration object that has the various properties/methods set to the required values.

Return value​

Type: void

Remarks​

The typical sequence for configuring a test is:

  1. Create a Configuration object.
  2. Assign to the properties you want to set up, and call the various methods.
  3. Create an Eyes instance.
  4. Call the Eyes.SetConfiguration method with the configuration object.
  5. 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:

  1. Get the current configuration using Eyes.GetConfiguration to a local variable.
  2. Make changes to the local configuration value.
  3. Assign the local configuration object to the Eyes instance using Eyes.SetConfiguration.

SetScrollToRegion method​

Syntax​

eyes.SetScrollToRegion(shouldScroll);

Parameters​

shouldScroll

Type: bool

If set to true, then before a region is matched, Eyes will automatically scroll to the region. If set to false, then Eyes will not scroll.

Return value​

Type: void

Properties​

AgentId property​

Syntax​

string value; // give relevant initial value
eyes.AgentId  = value;
value = eyes.AgentId

Type: string

Remarks​

To take effect, this property must be assigned before the call to Open.

ApiKey property​

Syntax​

string value; // give relevant initial value
eyes.ApiKey  = value;
value = eyes.ApiKey

Type: string

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.

AppName property​

Syntax​

string value; // give relevant initial value
eyes.AppName  = value;
value = eyes.AppName

Type: string

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.

BaselineBranchName property​

Syntax​

string value; // give relevant initial value
eyes.BaselineBranchName  = value;
value = eyes.BaselineBranchName

Type: string

BaselineEnvName property​

Syntax​

value = eyes.HostOS

Type: string

IgnoreCaret property​

Syntax​

bool value; // give relevant initial value
eyes.IgnoreCaret  = value;
value = eyes.IgnoreCaret

Type: bool

Remarks​

We recommend using HideCaret or SetHideCaret since this eliminates cursor related artifacts instead of detecting and ignoring them.

IsDisabled property​

eyes.MatchLevel  = value;
value = eyes.MatchLevel

Type: MatchLevel

Remarks​

For a full description of the affect of each match levels and the different ways to apply them to tests, checkpoints and regions, How to use Eyes match levels.

MatchTimeout property​

Syntax​

TimeSpan value; // give relevant initial value
eyes.MatchTimeout  = value;
value = eyes.MatchTimeout

Type: TimeSpan

Remarks​

You can override the default timeout set by this property for a specific set checkpoint by passing a timeout to one of the check_XXXX methods that support a timeout parameter, e.g. CheckWindowYou can also override the timeout for a specific test using the check fluent Timeout method

Proxy property​

Syntax​

WebProxy value; // give relevant initial value
eyes.Proxy  = value;
value = eyes.Proxy

eyes.ViewportSize  = value;
value = eyes.ViewportSize

Type: RectangleSize

ViewportSize property​

Syntax​

RectangleSize value; // give relevant initial value
Eyes.ViewportSize  = value;
value = Eyes.ViewportSize

Type: RectangleSize

Remarks​

  • Call this method before the call to Eyes.Open. Then, when calling the open method, don't pass the viewportSize parameter.
