### Question:
DBaseFileAttributeProvider extends AbstractAttributeProvider { @Override @Pure public boolean hasAttribute(String name) { return this.accessor.hasAttribute(name); } DBaseFileAttributeProvider(DBaseFileAttributeAccessor accessor); @Override @SuppressWarnings("checkstyle:nofinalizer") @Deprecated(since = "17.0", forRemoval = true) void finalize(); @Pure URL getResource(); @Pure int getRecordNumber(); @Override void freeMemory(); @Override @Pure Collection<String> getAllAttributeNames(); @Override @Pure Collection<Attribute> getAllAttributes(); @Override @Pure Map<AttributeType, Collection<Attribute>> getAllAttributesByType(); @Override @Pure AttributeValue getAttribute(String name); @Override @Pure AttributeValue getAttribute(String name, AttributeValue default_value); @Override @Pure Attribute getAttributeObject(String name); @Override @Pure boolean hasAttribute(String name); @Override @Pure int getAttributeCount(); @Override @Pure void toMap(Map<String, Object> mapToFill);  }### Answer:
@Test public void testHasAttribute() { assertTrue(this.provider.hasAttribute("SOURCE")); assertTrue(this.provider.hasAttribute("CATEGORIE")); assertTrue(this.provider.hasAttribute("NATURE")); assertTrue(this.provider.hasAttribute("HAUTEUR")); assertFalse(this.provider.hasAttribute("NOFIELD")); assertFalse(this.provider.hasAttribute("NEWFIELD")); }
