Hi all,<\/p>\n
Here I am giving a brief introduction about unit testing of services in grails. I will explain it with the help of a simple example.<\/p>\n
We have a domain class named: Item
\nTwo services : UtilService and ItemService<\/p>\n
Code of UtilService.groovy<\/p>\n
\/\/ class UtilService code\r\n\r\nclass UtilService {\r\n boolean transactional = true\r\n Integer calculatePrice(Item item, Integer vat, Integer profit) {\r\n return item.price * vat * profit\r\n }\r\n}\r\n<\/pre>\nCode of ItemService.groovy<\/p>\n
\/\/ ItemService class code\r\n\r\nclass ItemService {\r\n boolean transactional = true\r\n def utilService\r\n Integer calculateCost(Item item,Integer quantity) {\r\n Integer price = utilService.calculatePrice(item,5,8)\r\n Integer totalCost = price * quantity\r\n return totalCost\r\n }\r\n}\r\n<\/pre>\nOur test case:-<\/p>\n
void test_calculateCost() {\r\n \/\/ Step-1: Mocking the domain class\r\n def instance = [new Item()]\r\n mockDomain(Item, instance)\r\n\r\n\/\/Step-2: Mocking the service and its method used in the function that has to be tested\r\n def otherService = mockFor(UtilService)\r\n otherService.demand.calculatePrice(1) {l,m, n -> return 150}\r\n\r\n\/\/ Step-3: creating the instance of our service\r\n def itemService = new ItemService()\r\n itemService.utilService = otherService.createMock()\r\n\r\n\/\/ Step-4: Calling the method to be tested\r\n def amount = itemService.calculateCost(instance[0],10)\r\n\r\n assertEquals 1500, amount\r\n }\r\n<\/pre>\nHope it helps.
\nFor more…. wait for the next blog on unit testing<\/p>\n
