the class MacroHierarchyUnitTest method testMacroHierarchy.

// Finally, the EmbeddedDisplayWidget can replace macros,
// but testing that requires the runtime to load the embedded content
// --> Leaving that to examples/macros

    assertThat(name_prop.getValue(), equalTo("New Name"));
    assertThat(updates.get(), equalTo(2));
    // Setting the specification to something that does
