我在 Grails 2.x 中创建了一个集成测试，目的是测试几个控制器，以便在 Web 应用程序中模拟完整的用户流程。
首先，我保存了两个简单的域对象记录，在我的测试用例中实例化了两个控制器实例。这两个简单的类是： - 类别（产品的类别）和 - 商店（销售产品的迷你市场）我编写了两种测试方法来控制控制器实例（StoreController 和 CategoryController）并且工作正常，创建了一个类别记录并也有几个店铺记录。
然后，我编写了第三种方法来尝试保存产品记录。该记录必须引用一个类别。因此，我从以前的方法中获取类别实例，并尝试将其传递给 ProductController 以及其他 Product 参数。
由于未知原因，我只能通过在 Web 浏览器中输入数据的 Web 应用程序实例来创建产品记录，而不能通过测试类代码创建产品记录。我认为问题出在 Product 和 Category 之间的关系上，但我不知道应该如何将参数从测试用例传递给 ProductController 以创建新的 Product 记录。
这是我的产品类：
class Product {
int id
String barCode
String shortDesc
String longDesc
String format
Category category
static belongsTo = [category: Category]
//static hasManySurveyRecord = [surveyRecord: SurveyRecord]
static constraints = {
id editable: false
barCode blank: false, nullable: false, maxSize: 64
shortDesc blank: false, nullable: false, maxSize: 32
longDesc blank: false, nullable: false, maxSize: 128
category blank: false
}
static mapping = {
table 'product_catalog'
version false
columns {
id column: 'id'
barCode column: 'bar_code'
shorDesc column: 'short_desc'
longDesc column: 'long_desc'
format column: 'format'
}
}
String toString() {
return longDesc
}
}
这是我的类别课程：
class Category {
int id
String description
static hasManyProduct = [products: Product]
static constraints = {
id editable: false
description blank: false, nullable: false, maxSize: 64
}
static mapping = {
table 'categories'
version false
columns {
id column: 'id'
description column: 'description'
}
}
String toString() {
return description
}
}
这是我对这个应用程序的集成测试：
static transactional = false
static storeList = []
static storesData = []
static categoryIns
static categoryData = []
static productIns = new Product()
static productData = []
@Before
void setup() {
storesData.add([zipCode: 926260001, address: "first test avenue, first city, CA" , description: "first testing store"])
storesData.add([zipCode: 926260002, address: "second test avenue, second city, CA" , description: "second testing store"])
storesData.add([zipCode: 926260003, address: "third test avenue, third city, CA" , description: "third testing store"])
storesData.add([zipCode: 926260004, address: "fourth test avenue, fourth city, CA" , description: "fourth testing store"])
storesData.add([zipCode: 926260005, address: "fifth test avenue, fifth city, CA" , description: "fifth testing store"])
storesData.add([zipCode: 926260006, address: "sixth test avenue, sixth city, CA" , description: "sixth testing store"])
storesData.add([zipCode: 926260007, address: "seventh test avenue, seventh city, CA", description: "seventh testing store"])
storesData.add([zipCode: 926260008, address: "eighth test avenue, eighth city, CA" , description: "eighth testing store"])
categoryData = [description: "testing category"]
productData = [barCode: "0114B", shorDesc: "The short testing description", longDesc: "The long testing description ....", format: "1 LT"]
}
@Test
void _01__createStores() {
def storeCtl = new StoreController()
(0..7).each { i ->
def model = storeCtl.create()
assert model.storeInstance != null
storeCtl.response.reset()
storeCtl.params.putAll( storesData.get(i) )
storeCtl.save()
assert Store.count() == (i+1)
}
storeList.addAll( Store.list() )
assert storeList.size() == Store.list().size()
}
@Test
void _02__createCategory() {
// Test if there is a previous store list created
assert storeList.size() == Store.list().size()
def categoryCtl = new CategoryController()
def model = categoryCtl.create()
assert model.categoryInstance != null
categoryCtl.response.reset()
categoryCtl.params.putAll( categoryData )
categoryCtl.save()
assert Category.count() == 1
categoryIns = Category.list()[0]
}
@Test
void _03__createProduct() {
// Test if there is a previous store list created
assert storeList.size() == Store.list().size()
// Test if there is a previous category created
assert categoryIns != null
assert categoryIns.id > 0
def productCtl = new ProductController()
def model = productCtl.create()
assert model.productInstance != null
productCtl.response.reset()
productData.put("category", [id: categoryIns.id])
productData.put("category.id", categoryIns.id)
productCtl.params.putAll( productData )
//productCtl.params.category = Category.get(categoryIns.id)
productCtl.save()
assert Product.count() == 1
}
这是我的 ProductController 代码摘录：
def save() {
def productInstance = new Product(params)
if (!productInstance.save(flush: true)) {
render(view: "create", model: [productInstance: productInstance])
return
}
flash.message = message(code: 'default.created.message', args: [message(code: 'product.label', default: 'Product'), productInstance.id])
redirect(action: "show", id: productInstance.id)
}
