+Scenario 1: Encrypt method correctly handles a valid BitSet input.
+
+Details:
+  TestName: encryptWithValidBitSetInput
+  Description: Verify that the encrypt method successfully processes a valid BitSet input and produces the correct encrypted BitSet output. The test ensures keyStreamGenerator generates the key stream and checks if the XOR operations apply without errors.
+
+Execution:
+  Arrange:
+    - Initialize a valid BitSet instance to represent plainTextBits.
+    - Set up a mock A5KeyStreamGenerator to provide a predefined key stream matching the KEY_STREAM_LENGTH.
+    - Inject the mock keyStreamGenerator into the A5Cipher instance.
+
+  Act:
+    - Invoke the encrypt method with the valid BitSet instance.
+
+  Assert:
+    - Ensure that the result matches the expected encrypted BitSet produced by the XOR combination of plainTextBits and the generated key stream.
+
+Validation:
+  - Confirms that encrypt performs its logic correctly with valid inputs.
+  - Ensures that the key stream generation integrates seamlessly into the encryption process.

+Details:

+
+Execution:
+  Arrange: Create an instance of the A5Cipher class, set up a mocked keyStreamGenerator object with mock behavior for the reInitialize method, and ensure the keyStreamGenerator object is assigned correctly.

+  Assert: Verify that the reInitialize method is called exactly once on the keyStreamGenerator using mocking framework assertions.
+
+Validation:
+  Confirm that the method correctly delegates the state reset functionality to the KeyStreamGenerator. This ensures proper behavior in cryptographic usage where counter resets are expected for security or operational purposes.
