Reactive Scenarios enable you to use C# code to control execution of the Jobs (TestCases) in a Scenario. Control flow logic such as loops, branching, and switch cases are supported. Some examples of capabilities provided by Reactive Scenarios:
•Run a TestCase with a value or set of values (such as 12 volts), then repeat the same test case with another value (such as 10 volts).
•Stop the Scenario or a TestCase based on the value of any Signal or on the Pass/Fail status of the Scenario, any TestCase, or any Signal.
•Execute TestCase A, then if it passes execute TestCase B, but execute TestCase C if A failed. See example.
•If a TestCase fails, repeat it with another set of Calibration values.
The Reactive Code can access the following types of data, which can be used in the Scenario logic:
•Pass/Fail status of Scenarios and TestCases
•Execution state of TestCases (Completed, IsRunning, or NotRun)
•Commanded or Actual values of Signals
To open the Reactive Code dialog, select View->Reactive Code from the MxVDev main menu. Click on an open Scenario to select it. (To see Reactive Code for a TestCase, open and select the TestCase.)
To use Reactive Scenario code, select the Enabled checkbox at the bottom of the Reactive Code panel.
Select a tab: Start, TestCase Complete, Tick, or All Code:
•Start: This method is executed when the Scenario starts.
•TestCase Complete: This method is executed when any TestCase in the Scenario completes.
•Tick: This method is executed each time the Scenario is ticked. The tick interval of the Scenario is specified in the Tick Settings in the Constructs pane.
•Transition Received: This method is executed when a transition occurs on a response Signal or on an included Stimulus Signal.
•Other: Use this tab for static declarations and method definitions. This code is compiled, but executed only if called from user code.
•References: Use this tab to add or remove DLL references to your code.
•All Code: This tab displays all the generated code associated with the Scenario.

To use an construct listed, select it and click Insert to put it into your user code.
To include a Signal in your Reactive Code, select its box in the Include column:
