### Question:
MultiValueRequestParameters implements RequestParameters { @Override public boolean addParameterStringValues(final String parameter, final String... values) { final List<String> valuesAsList = getVarArgsAsList(values); return addParameterValues(parameter, valuesAsList); } MultiValueRequestParameters(); @Override boolean isEmpty(); @Override boolean isEmpty(final String parameter); @Override boolean contains(final String parameter); @Override boolean isSingleValue(final String parameter); @Override boolean hasMultipleValues(final String parameter); @Override String getSingleValue(final String parameter); @Override Collection<String> getParameterNames(); @Override Collection<String> getAllValues(final String parameter); @Override boolean mergeWith(final RequestParameters parameters); @Override boolean addParameterValue(final String parameter, final String value); @Override boolean addParameterEnumValues(final String parameter, final Enum<?>... values); @Override boolean addParameterStringValues(final String parameter, final String... values); @Override boolean addParameterValues(final String parameter, final Iterable<String> values); @Override Collection<String> remove(final String parameter); @Override void removeAll(); static final String SERVICE_VERSION; static final String SERVICE_TYPE; }### Answer:
@Test public void shouldIndicateSizeChangeWhenAddingMultipleValues() { assertThat(requestParameters.addParameterStringValues("version", "1.0.0", "2.0.0"), is(true)); assertThat(requestParameters.addParameterStringValues("version", "1.0.0", "2.0.0"), is(false)); }
