Version 7.11.0
===============

Minor release: a new **test-case generator** and a richer **GUI input/form
metamodel**. Adds a ``pytest`` + Hypothesis test-suite generator and extends the
GUI language with alerts, structured input fields, and forms — wired end-to-end
through the metamodel, the React generator, the bidirectional web-editor
converters, and the Web Modeling Editor. Existing generators' output for
existing models is unchanged.

Test Case Generator
-------------------

* New :doc:`../../generators/test_case` (``besser.generators.testgen.TestCaseGenerator``)
  emits a ``pytest`` + `Hypothesis <https://hypothesis.readthedocs.io/>`_ test
  suite from a ``DomainModel``. It produces three layers: **structural tests**
  (each class is concrete, the constructor signature carries every attribute,
  one ``property`` per attribute, enumeration literals are present), **Hypothesis
  property-based tests** (a ``st.builds`` strategy per class, instantiation
  invariants, attribute setter round-trips, and association-multiplicity
  contracts), and **OCL post-condition tests** translated from each method's
  post-conditions.
* Output is **deterministic**: model elements are emitted in stable ``timestamp``
  order, so regenerating the suite for an unchanged model produces a byte-identical
  ``test_hypothesis.py``.
* Registered in the web-editor generator registry under ``test_case`` (category
  ``object_oriented``, output ``test_hypothesis.py``) and exposed in the Web
  Modeling Editor generation menu as **Python Test Cases**.

GUI metamodel — input and form semantics
-----------------------------------------

* Extended ``besser.BUML.metamodel.gui``: a new ``Alert`` component
  (``severity`` via ``AlertSeverity``, ``title``, ``content``, ``dismissible``);
  ``InputField`` gains ``label``, ``placeholder``, ``required``,
  ``default_value``, ``options`` (a list of ``SelectOption``), ``min_value``,
  ``max_value``, ``step`` and ``multiple``, alongside additional
  ``InputFieldType`` values; and ``Form`` gains ``title``, ``submit_label``,
  ``show_cancel``, ``cancel_label`` and ``columns``.
* The :doc:`React generator <../../generators/react>` renders the new input
  components, so a No-Code GUI diagram that uses them produces working React
  input controls.
* The web-editor converters handle the new constructs in **both** directions —
  ``json_to_buml`` parses them from the editor and ``buml_to_json`` serializes
  them back — so a model exported to B-UML and re-imported keeps its alerts,
  input-field attributes and forms (the reverse path previously dropped them).

Web Modeling Editor
-------------------

* **GUI input blocks**: the No-Code GUI editor palette gains the new
  input/alert/form blocks (frontend ``#155``).
* **Test-case generation**: the generation menu offers *Python Test Cases*,
  wired to the ``test_case`` backend generator (frontend ``#138``).

Internal updates
----------------

* CI prunes dangling Docker images after the Web Modeling Editor deploy step
  (``#566``) so the runner disk does not fill up across successive deploys.
