### Question:
FilterResolver { public boolean hasMobileFilter() { return parameters.getMobile() != null; } FilterResolver(IoParameters parameters); boolean hasMobileFilter(); boolean hasInsituFilter(); boolean isMobileFilter(); boolean isInsituFilter(); boolean shallIncludeAllDatasets(); boolean isSetPlatformTypeFilter(); boolean shallIncludeAllDatasetTypes(); boolean shallIncludeDatasetType(String datasetType); boolean shallIncludeAllObservationTypes(); boolean shallIncludeObservationType(String observationType); boolean shallIncludeAllValueTypes(); boolean shallIncludeValueType(String valueType);  }### Answer:
@Test public void when_defaults_then_stationaryFilterActive() { FilterResolver resolver = createResolver(createDefaults()); Assertions.assertFalse(resolver.hasMobileFilter()); }
@Test public void when_defaults_then_mobileFilterActive() { FilterResolver resolver = createResolver(createDefaults()); Assertions.assertFalse(resolver.hasMobileFilter()); }
@Test public void when_setAllDatasets_then_stationaryFilterActive() { IoParameters parameters = createDefaults(); FilterResolver resolver = createResolver(parameters); Assertions.assertFalse(resolver.hasMobileFilter()); }
@Test public void when_setAllDatasets_then_mobileFilterActive() { IoParameters parameters = createDefaults(); FilterResolver resolver = createResolver(parameters); Assertions.assertFalse(resolver.hasMobileFilter()); }
