### Question:
ExpressionLanguage implements DMNProperty { public String getValue() { return value; } ExpressionLanguage();  ExpressionLanguage(final String value); ExpressionLanguage copy(); String getValue(); void setValue(final String value); @Override boolean equals(final Object o); @Override int hashCode();  }### Answer:
@Test public void testZeroParameterConstructor() { this.expressionLanguage = new ExpressionLanguage(); assertEquals("", expressionLanguage.getValue()); }
@Test public void testOneParameterConstructor() { this.expressionLanguage = new ExpressionLanguage(VALUE); assertEquals(VALUE, expressionLanguage.getValue()); }
