-FIXME: add a description
+== Why is this an issue?
 
-// If you want to factorize the description uncomment the following line and create the file.
-//include::../description.adoc[]
+Test files in JavaScript and TypeScript are meant to contain test cases. These test cases are used to verify the functionality of your code and ensure that it behaves as expected. If a test file doesn't contain any test cases, it's not serving its purpose.
 
-== Why is this an issue?
+A test file without test cases might indicate:
 
-FIXME: remove the unused optional headers (that are commented out)
+* An incomplete test suite: Perhaps the developer started writing tests but didn't finish.
+* A mistake: The developer might have accidentally deleted the test cases or moved them to another file.
 
-//=== What is the potential impact?
+This rule flags any file that has a ``++.test++`` or ``++.spec++`` suffix but does not contain any test cases defined using the ``++it++`` or ``++test++`` functions from Jasmine, Jest, Mocha, or Node.js testing API. The alternative forms ``++it.only++`` and ``++test.only++`` are recognized, but their use is generally discouraged.
 
 == How to fix it
-//== How to fix it in FRAMEWORK NAME
+
+To fix a test file that doesn't contain any test cases, you should add test cases or delete the file if it isn't needed.
