The main challenge on the user side is comprehensibility.
With that many properties, and considering the tendency for properties to accrete in user builds over time, it is important for users to understand the contracts tied to the features.
For instance, whether they use an internal property (intentionally or accidentally), or whether they use an unstable feature that can change at any time.

        super.setUp(testInfo);
        fessLabels = new FessLabels();
    }

     * Test that assertPropertyNotNull throws exception for null input

        if (options.sessionId != null) {
            options.sessionId = options.sessionId.replaceAll("-", "_");

A downside of this structure is that it is difficult to do focused work on the Gradle UI.

## Decision

Introduce a "UI" architecture module to the core platform, and move the user interaction services to this new module.

This includes:

        assertEquals(message, exception.getMessage());
        assertNull(exception.getCause());
    }

    @Test
    public void test_instanceOfFessSystemException() {
        // Test that ScriptEngineException is an instance of FessSystemException
        ScriptEngineException exception = new ScriptEngineException("test");

        assertTrue(exception instanceof FessSystemException);
