Examples

using OpenQA.Selenium;
using static CSF.Screenplay.Selenium.PerformableBuilder;

// Within the logic of a custom task, deriving from IPerformable
public async ValueTask PerformAsAsync(ICanPerform actor, CancellationToken cancellationToken = default)
{
    // ... other performance logic
    await actor.PerformAsync(TakeAndSaveAScreenshot().WithTheName("Shopping cart items"), cancellationToken);
    // ... other performance logic
}

Remarks

Use this task via one of the builder methods TakeAndSaveAScreenshot() or TakeAndSaveAScreenshotIfSupported(). This performable task is a composition of two others: TakeScreenshot and SaveScreenshot. See the documentation for this question and action for more information.

As with SaveScreenshot, this performable requires the actor to have the ability GetAssetFilePaths.

Constructors

TakeAndSaveScreenshot(string, ScreenshotImageFormat, bool)

Initializes a new instance of the TakeAndSaveScreenshot class.

public TakeAndSaveScreenshot(string name = null, ScreenshotImageFormat format = ScreenshotImageFormat.Png, bool throwIfUnsupported = true)

Parameters

name string

An optional human-readable name for the screenshot.

format ScreenshotImageFormat

An optional image format by which to save the screenshot.

throwIfUnsupported bool

If set to true, throws an exception if the WebDriver does not support taking screenshots.

Methods

GetReportFragment(Actor, IFormatsReportFragment)

Gets a fragment of a Screenplay report, specific to the execution (performables) or gaining (abilities) of the current instance, for the specified actor.

public ReportFragment GetReportFragment(Actor actor, IFormatsReportFragment formatter)

Parameters

actor Actor

An actor for whom to write the report fragment

formatter IFormatsReportFragment

A report-formatting service

Returns

ReportFragment

A human-readable report fragment.

Examples

For a performable which clicks a button (where the button itself has been constructor-injected into the performable instance), then a suitable return value might be a formatted string such as {Actor name} clicks {Button}, where the two placeholders indicated by braces: {} are substituted with the actor's Name and a string representation of the button.

For a performable which reads the temperature from a thermometer, a suitable return value might be a string in the format {Actor name} reads the temperature.

For an ability which allows the actor to wash dishes then a suitable return value might be a string in the format {Actor name} is able to wash the dishes.

Remarks

Implementers should return a string which indicates that the named actor is performing (present tense) the performable, for types which also implement a performable interface. For types which represent abilities, the implementer should return a string which indicates that the named actor is able to do something. In particular for abilities, to make them easily recognisable in reports, it helps to stick to the convention {Actor name} is able to {Ability summary}.

For performables which return a value (Questions, or Tasks which behave like Questions), there is no need to include the returned value within the report fragment. The framework will include the return value in the report and will format it via a different mechanism.

Good report fragments are concise. Be aware that report fragments for Tasks (which are composed from other performables) do not need to go into detail about what they do. Users reading Screenplay reports are able to drill-down into Tasks to see what they are composed from, so if the user is curious as to what the task does, it is easy to discover. It is also strongly recommended to avoid periods (full stops) at the end of a report fragment. Whilst report fragments tend to be complete sentences, punctuation like this is distracting and reports are seldom presented as paragraphs of prose.

PerformAsAsync(ICanPerform, CancellationToken)

Performs the action(s) are represented by the current instance.

public ValueTask PerformAsAsync(ICanPerform actor, CancellationToken cancellationToken = default)

Parameters

actor ICanPerform

The actor that is performing.

cancellationToken CancellationToken

An optional cancellation token by which to abort the performable.

Returns

ValueTask

A task which completes when the performable represented by the current instance is complete.
