This section explains how to use the Forced Interactions feature of Xray Test Case Designer.

Forced Interactions are a method to train the model about specific business rules that must always be considered on the generated tests, as long as the required values and outcomes. 
With Forced Interactions, the system will always make sure ensure these interactions are added to your model output.

...

  • Customer status must be Regular
  • Loan to value ratio must be 90%
  • Loan The loan amount must be Large
  • And the property needs to be In a Flood Zone

(Optional) Type the name and/or number of your forced scenario

UI Step

(Optional) Type its expected result.

UI Step

Select only the Values you need to trigger your business requirement, then save.

  1. I.e., if our plan has 10 parameters, but the business rule only needs 4 to trigger, we include just those 4 in the forced interaction.

Info
titleKeep the following usage tips in mind when using Forced Interactions
  1. This feature is not just for “official requirements.” Consider including other critical ideas in your Xray Test Case Designer generated suite, like a forced scenario that contains the most common Value for each Parameter (i.e., “Happy Path”).

  2. As shown above, you don’t need to specify every Value. In fact, it’s better if you only force the Values needed to trigger the requirement/business rule. That way, the most variation is possible in your Xray Test Case Designer generated tests is possible.

  3. Keep the concept of “Expected Results” clearly separated in your mind from ordinary Parameters and Values. Treat them differently from each other as you enter your plans. Typically, do not enter Expected Result values in the “Parameters” screen. The primary places you should enter the Expected Result are the “Forced Interactions” and “Scripts” screens. You can read more in the "How to Handle Expected Results" article from the Test Design Principles section.

  4. Use this feature selectively. Remember that many combinations will automatically appear in your Xray the Test Case Designer generated models without you needing to do anything special. If Suppose you have a business rule that only requires two Values to appear together, for example. In that case, that requirement will already be satisfied automatically whenever you create a 2-way (“pairwise”) set of tests. If you’re creating a 2-way set of tests, you would only need to use this special feature when you’re trying to ensure that 3 or more specific Values get tested together in a single test case.

Import Forced Interactions

You are able to can import forced interactions, that which allows you to upload data-driven scenarios. Once you navigate to the screen, you should see the icon on the left side.

As before, we recommend using the Excel template (you can download it from the link at the top of the dialog) and pasting your scenarios in the table format to the cell D1 (given you have parameter names).
