Get/Set Extracted Variables in Code

There are test scenarios in which you need to take, for example, the text content of an element and reuse it later in the test steps. Test Studio allows you to easily accomplish this by using an Extraction step.

The extracted variable can be used in a coded step as well - that way you can modify the value of the extracted variable in various ways, or use this to determine how a test should continue. In the cases when the variable's value requires any modification, you can assign the new value back to the same variable or a new one, and then use this back in the Test Studio UI steps.

Get the Value of an Extracted Variable

Use the GetExtractedValue() method to use the value of an extracted variable in a coded step:

object myData = GetExtractedValue("ExtrVarName");
Dim myData As Object = GetExtractedValue("ExtrVarName")

Set a Value to an Extracted Variable

Use the SetExtractedValue() method to set the value of an extraction variable so it can be used later in a standard action or verification step:

string newValue = "newValueToAssign";
SetExtractedValue("ExtrVarName", newValue);
Dim newValue As String = "newValueToAssign"
SetExtractedValue("ExtrVarName", newValue)

Example of Using the Extracted Variables in Code

Here is a sample scenario, which demonstrate how to use the extracted variables in code:

  • extract the text content of an element;
  • add a coded step in the test and assign the value of the extracted variable to a variable in the code;
  • modify the value as required;
  • assign the new value to an extracted variable to be used in the steps;

To explore the example you can download a sample project here.

The baseline of code to use should look similar to the one below:

// Assign the value of the extracted variable from the recorded step 'ExtractedVar' to a variable to use in the code
var extrVariableInCode = GetExtractedValue("ExtractedVar");

// Insert the necessary custom code to modify the exctracted value and assign it to a string variable
string newValue = "newValueToAssign";

// Assign the modified variable to a new extracted variable
SetExtractedValue("ModifiedExtrVariable", newValue);
' Assign the value of the extracted variable from the recorded step 'ExtractedVar' to a variable to use in the code
Dim extrVariableInCode As Object = GetExtractedValue("ExtractedVar")

' Insert the necessary custom code to modify the exctracted value and assign it to a string variable
Dim newValue As String = "newValueToAssign"

' Assign the modified variable to a new extracted variable
SetExtractedValue("ModifiedExtrVariable", newValue)
