As a result, the test formally exists, but provides almost no real benefit. --- ### **The main reasons snapshots are criticized** **1) Tests stop checking behavior** A snapshot captures a huge chunk of markup or data. It does not answer the question *"does the component work correctly?"*, it only answers *"has nothing changed line by line?"* **2) "Update the snapshot" becomes a reflex** In most cases, developers simply click *update snapshot* without even reading the changes. Tests turn into noise instead of protection. **3) Hard to notice the real problem** The markup can be large. In a diff it is easy to miss a real bug among dozens of insignificant changes (for example, an extra div gets lost among hundreds of lines). **4) Fragility and false positives** Any small thing breaks the snapshot: a line wrap, an attribute, a class, formatting. The component can be completely functional, yet the test fails. **5) No explicit test intent** A good test answers a clear question: *"If the user clicks the button, what happens?"* A snapshot test answers: *"The output should be the same as it once was"* This is too vague. --- ### **Summary** Snapshots are often called an anti-pattern because they: - poorly reflect the component's true logic, - quickly turn into routine, - give a false sense of security instead of real quality control. That is why experienced teams prefer **meaningful, targeted behavior checks** instead of "huge snapshots of everything under the sun."For the reviewerNote to the moderator (optional)Visible only to the moderator.
