14. Tip: Follow the "Goldilocks Rule" to determine the correct amount of detail
This lesson provides guidance about how much detail you should include in your test scripts.
The "Goldilocks Rule" helps you find an amount of details that is "just right" for your set of tests.
If your tests cover a large scope, as in a set of end-to-end tests of a process, you focus first on entering only the most important elements of that process into Hexawise. If your tests cover a small scope, as in tests that focus on a few items on a single screen, the amount of detail you will want to include in Hexawise is higher.
Too much detail can get in the way of your testing objectives. Treat "passive" fields different than "active" fields.
- Passive fields should not impact business rules. An example or a passive field would be an optional text box that a customer service representative might choose to enter notes into during a call with a customer. If the information entered in that box should not impact the outcome of the transaction, focus less of your testing efforts on it.
- Active fields should impact business rules. An example would be the selection of a specific model of cell phone. When a customer selects the latest model iPhone, the order processing software should recognize that fact and ensure that the customer is charged the appropriate amount for it, etc.
As you enter your test inputs, consider different possible options for how you select them.
Red: Don't include any Parameter related to it in the plan; leave it out of Hexawise entirely
Black: Include a Parameter, but only use vague tester instructions in the three Values (e.g., Valid, Invalid, Blank)
Blue: Include a Parameter, but leave a lot of discretion for the tester in the way you describe the Values
Green: Include multiple Parameters, and instruct the tester to select a test condition that meets all of those criteria (e.g., in the example above, one of the test instructions might read, "for this test, select an English language book that is rarely ordered that was first published more than 5 years ago and order a softcover copy of it."
