`UiPath.Testing.Activities.VerifyRange`

## Description

Verifies if an expression is located or not within a given range. The expressions tested with this activity must be inserted in their respective property fields.

## Project compatibility

**Windows - Legacy** | **Windows** | **Cross-platform**

## Windows - Legacy configuration

#### **Designer panel**

* **Expression** - The expression that you want to verify within a given range.
* **LowerLimit** - The lower bound of the range.
* **TakeScreenshotIfFailed** - If set to `True`, takes a screenshot of the target process if the verification has failed.
* **TakeScreenshotIfSucceded** - If set to `True`, takes a screenshot of the target process if the verification has been successful.
* **UpperLimit** - The upper bound of the range.
* **VerificationType** - A drop-down list containing the operators that you can use to verify the expression. The following options are available:
  + **is within**
  + **is not within**

#### **Properties panel**

**Common**

**DisplayName** - The display name of the activity.

**Input**
* **ContinueOnFailure** - Specifies if the automation should continue even when the activity throws an error. This field only supports Boolean values (True, False). The default value is True. As a result, the execution of the project continues regardless of any error. If the value is set to False, and an error is thrown, the execution of the project stops.
  :::note
  If this activity is included in **Try Catch** and the value of the **ContinueOnFailure** property is True, no error is caught when the project is executed.

**Messages**
* **AlternativeVerificationTitle** - Specifies an alternative display name. This property overrides the default `DisplayName`, which is the verification activity name that shows up in Orchestrator.
* **OutputMessageFormat** - Specifies the format of the output message. To set a global output message format, see [Project Settings](https://docs.uipath.com/activities/other/latest/workflow/project-settings-testing). For more information, check the **Configuring the OutputMessageFormat** section.

**Misc**

**Private** - If selected, the values of variables and arguments are no longer logged at Verbose level.

**Output**

**Result** - Reflects the state of the verification activity. You can use this to send notifications or create reports for failed verifications.

#### **Advanced options**

**Input**
* **ContinueOnFailure** - Specifies if the automation should continue even when the activity throws an error. This field only supports Boolean values (True, False). The default value is False. As a result, if the field is blank and an error is thrown, the execution of the project stops. If the value is set to True, the execution of the project continues regardless of any error.
* **TakeScreenshotIfFailed** - If set to `True`, takes a screenshot of the target process if the verification has failed.
* **TakeScreenshotIfSucceded** - If set to `True`, takes a screenshot of the target process if the verification has been successful.

**Messages**
* **AlternativeVerificationTitle** - Specifies an alternative display name. This property overrides the default `DisplayName`, which is the verification activity name that shows up in Orchestrator.
* **OutputMessageFormat** - Specifies the format of the output message. To set a global output message format, see [Project Settings](https://docs.uipath.com/activities/other/latest/workflow/project-settings-testing).

## Configuring the OutputMessageFormat

The **OutputMessageFormat** property can be configured with supported arguments, that act as placeholders for the values used in the verification operation. These placeholders are automatically populated with the variables or values you defined when invoking the activity at runtime.

For the Verify Range activity, you can implement the following supported arguments when creating an output message:

* `{Expression}`: Represents the value of the expression you provided for the **Expression** property.
* `{ExpressionText}`: Represents the text of the expression you inserted for the **Expression** property.
* `{Operator}`: Corresponds to the **Verification Type** property.
* `{LowerLimit}`: Indicates the variable value you used for the **LowerLimit** property.
* `{LowerLimitText}`: Refers to the textual representation of the variable used for the **LowerLimit** property.
* `{UpperLimit}`: Represents the variable name used for the **UpperLimit** property.
* `{UpperLimitText}`: Points to the textual value of the variable used for the **UpperLimit** property.
* `{Result}`: Represents the activity output value, which is the verification result.

The following is an example showing how to configure an output message for the Verify Range activity: `"The {Expression} should be greater than {LowerLimitText}, and less than {UpperLimitText}"`

In the provided example, the placeholders within the curly brackets are replaced with the corresponding variable names and their values at runtime, providing a customized output message.
