### Question:
ELContextDecorator extends ELContext { @Override @SuppressWarnings("rawtypes") public void putContext(Class key, Object contextObject) { this.elContext.putContext(key, contextObject); } 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 shouldDecoratePutContext() throws Exception { Class<?> key = Object.class; Object contextObject = new Object(); this.decorator.putContext(key, contextObject); verify(this.decorated).putContext(key, contextObject); }
