Definition

Namespace: UiPath.Testing.API

Assembly: UiPath.Testing.Activities.Api (in UiPath.Testing.Activities.Api.dll)

`VerifyContains(object, object, string)`

bool VerifyContains(
    object firstExpression,
    object secondExpression
    [string outputMessageFormat]
)
bool VerifyContains(
    object firstExpression,
    object secondExpression
    [string outputMessageFormat]
)

firstExpression Object : The first expression.

secondExpression Object : The second expression.

outputMessageFormat String : The format of the output message. The supported arguments are:

{LeftExpression}
{LeftExpressionText}
{RightExpression}
{RightExpressionText}
{Result}
{Operator}

For instance, you can use the following output message format:

{LeftExpressionText}
    (with value {LeftExpression}) {Operator} {RightExpressionText} (with value {RightExpression})
    has result {Result}.
{LeftExpressionText}
    (with value {LeftExpression}) {Operator} {RightExpressionText} (with value {RightExpression})
    has result {Result}.

This message format indicates a comparison between two values or variables (LeftExpression and RightExpression), using a certain operator. The {Result} represents the outcome of this comparison.
