### Question:
APISchemaType extends SchemaType { public int getOperationCount() { return operationCount; } APISchemaType();  APISchemaType(APISchemaType template); int getOperationCount(); void setOperationCount(int operationCount); @Override SchemaElement cloneSchemaElement(); @Override SchemaType cloneSchemaType(); @Override String toString(); @Override boolean equals(Object objectToCompare);  }### Answer:
@Test public void testNullObject() { APISchemaType nullObject = new APISchemaType(); assertTrue(nullObject.getType() == null); assertTrue(nullObject.getGUID() == null); assertTrue(nullObject.getURL() == null); assertTrue(nullObject.getClassifications() == null); assertTrue(nullObject.getQualifiedName() == null); assertTrue(nullObject.getAdditionalProperties() == null); assertTrue(nullObject.getVersionNumber() == null); assertTrue(nullObject.getAuthor() == null); assertTrue(nullObject.getUsage() == null); assertTrue(nullObject.getEncodingStandard() == null); assertTrue(nullObject.getOperationCount() == 0); nullObject = new APISchemaType(null); assertTrue(nullObject.getType() == null); assertTrue(nullObject.getGUID() == null); assertTrue(nullObject.getURL() == null); assertTrue(nullObject.getClassifications() == null); assertTrue(nullObject.getQualifiedName() == null); assertTrue(nullObject.getAdditionalProperties() == null); assertTrue(nullObject.getVersionNumber() == null); assertTrue(nullObject.getAuthor() == null); assertTrue(nullObject.getUsage() == null); assertTrue(nullObject.getEncodingStandard() == null); assertTrue(nullObject.getOperationCount() == 0); nullObject = new APISchemaType(null); assertTrue(nullObject.getType() == null); assertTrue(nullObject.getGUID() == null); assertTrue(nullObject.getURL() == null); assertTrue(nullObject.getClassifications() == null); assertTrue(nullObject.getQualifiedName() == null); assertTrue(nullObject.getAdditionalProperties() == null); assertTrue(nullObject.getVersionNumber() == null); assertTrue(nullObject.getAuthor() == null); assertTrue(nullObject.getUsage() == null); assertTrue(nullObject.getEncodingStandard() == null); assertTrue(nullObject.getOperationCount() == 0); }
