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("").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.
