import XCTest

/// An extension for `XCTestCase` to express when a value is not relevant to the test outcome.
///
/// By using the `arbitrary` method, you can indicate that a certain value provided to the test does not play a significant role in the test scenario. It helps to avoid the creation of distracting variables whose values are inconsequential, focusing on what really matters in the test. The term 'arbitrary' is chosen to signify that the value is placeholder and could be substituted for any other value without affecting the test's behavior.
