### Question:
ELContextDecorator extends ELContext { @Override public boolean isPropertyResolved() { return this.elContext.isPropertyResolved(); } ELContextDecorator(ELContext elContext); @Override void setPropertyResolved(boolean resolved); @Override boolean isPropertyResolved(); @Override @SuppressWarnings("rawtypes") void putContext(Class key, Object contextObject); @Override @SuppressWarnings("rawtypes") Object getContext(Class key); @Override Locale getLocale(); @Override void setLocale(Locale locale); @Override ELResolver getELResolver(); @Override FunctionMapper getFunctionMapper(); @Override VariableMapper getVariableMapper();  }### Answer:
@Test public void shouldDecorateIsPropertyResolved() throws Exception { given(this.decorated.isPropertyResolved()).willReturn(true); boolean actual = this.decorator.isPropertyResolved(); assertThat(actual, is(true)); verify(this.decorated).isPropertyResolved(); }
