A value contained in double quotes (a string) in any Silk Test Workbench command can be replaced by a value in a variable. Typically this is a string variable. However, you can use variables for other data types such as Integer or Double when inputting values into a field.
The most common use of variables is as a substitute for a literal value used as input to a control, such as an edit box. Any method which enters data into a control, such as SetText() or TypeKeys() can substitute a variable for a literal value. To do this, declare the variable, assign its value, then replace the literal value with the variable. For example:
browser.DomTextField("@id='name-search:lastName'").SetText("Smith")
'becomes:
Dim lastName = "Smith"
.DomTextField("@id='name-search:lastName'").SetText(sLastName)
When selecting an item from a list or menu you can also use a variable for the entry selection. For example:
browser.DomListBox("@id='quick-link:jump-menu'").Select("Agent Lookup")
'becomes:
Dim selection = "Auto Quote"
browser.DomListBox("@id='quick-link:jump-menu'").Select(sSelection)
Values returned by methods or properties can be placed into a variable for evaluation. A common use of this is to return a value of the Boolean data type for evaluation in conditional logic. The following code shows how a Boolean value returned by the AllowsMultiSelect property is used to evaluate whether a list box control allows selection of multiple items.
Dim canMultiSelect As Boolean
' Returns true if the second list box in the window allows multiple selections
canMultiSelect = mainWindow.ListBox("[2]").AllowsMultiSelect
If canMultiSelect Then
MsgBox ("Employee selection list box allows to select multiple employees.")
Else
MsgBox ("Employee selection list box allows to only select one employees.")
EndIf
A variable can replace the raw attach name of a control. Use the string concatenate character &. For example:
browser.DomLink("@caption='Eye'").Select()
'could also read:
Dim sLink As String
sLink = "Eye"
browser.DomLink("@caption=" & sLink).Select()
Parameters in scripts can be shared with visual tests, so the same data can be used across a testing solution. For details, see Passing Data Between Scripts and Visual Tests.
