+ROOST_METHOD_HASH=sayHello_6027c429db
+ROOST_METHOD_SIG_HASH=sayHello_26998730d5
+
+Here are some JUnit test scenarios for the provided `sayHello()` method:
+
+Scenario 1: Verify the returned message
+
+Details:
+  TestName: returnedMessageIsHelloWorld
+  Description: This test verifies that the `sayHello()` method returns the expected "Hello world!" message.
+Execution:
+  Arrange: No specific arrangement is needed.
+  Act: Invoke the `sayHello()` method.
+  Assert: Use `assertEquals` to compare the returned value with the expected message "Hello world!".
+Validation:
+  The assertion verifies that the method returns the correct hardcoded message.
+  It ensures that the method's basic functionality of returning a greeting message is working as intended.
+
+Scenario 2: Check for non-null return value
+
+Details:
+  TestName: returnedMessageIsNotNull
+  Description: This test checks that the `sayHello()` method does not return a null value.
+Execution:
+  Arrange: No specific arrangement is needed.
+  Act: Invoke the `sayHello()` method.
+  Assert: Use `assertNotNull` to verify that the returned value is not null.
+Validation:
+  The assertion ensures that the method always returns a non-null value.
+  It validates that the method is properly returning a string message and not encountering any unexpected null values.
+
+Scenario 3: Verify the returned message type
+
+Details:
+  TestName: returnedMessageIsString
+  Description: This test verifies that the `sayHello()` method returns a value of type String.
+Execution:
+  Arrange: No specific arrangement is needed.
+  Act: Invoke the `sayHello()` method.
+  Assert: Use `assertTrue` to check if the returned value is an instance of String.
+Validation:
+  The assertion confirms that the method returns a value of the expected String type.
+  It ensures that the method signature is correctly defined to return a String and not any other data type.
+
+These test scenarios cover the basic functionality and return value of the `sayHello()` method. Since the method is simple and doesn't have any parameters or complex logic, there are limited scenarios to test. The tests verify the returned message, check for non-null return value, and ensure that the returned value is of type String.
