When is fine-tuning of a selector unnecessary?

Fine-tuning of a selector is unnecessary when using wildcards in selectors because wildcards are designed to allow for greater flexibility in identifying UI elements. Wildcards can match multiple elements based on a pattern rather than requiring an exact match. This means that when an element’s attributes may vary slightly or there are multiple similar elements, a wildcard effectively encompasses these variations without the need for adjustment or fine-tuning.

When using wildcards, the selector can adapt to changes in the specific attributes of an element that would typically require fine-tuning. For instance, if you are looking for buttons that have similar naming but differ by dynamic values, a wildcard would allow the selector to successfully locate the correct button without needing to alter the selector for each different state or version.

In contrast, static selectors are fixed and would not function properly if the UI changes, as they'd need revision to align with the new attributes. If the UI has not changed, fine-tuning might be unnecessary because the existing selectors should still be effective. Minimizing the application doesn’t impact the need for fine-tuning, as the elements are still present in the UI, albeit not visible.
