在我的项目中,我有许多彼此非常相似的域对象。在设计测试时,我意识到很多测试用例都是相同的。所以我设置自己创建一个BaseSpec,使我能够重用逻辑和代码。
假设我有以下两个grails域类:
class Product{
String productName
static constraints = {
name nullable: false, blank: false, unique: true
}
}
class Category{
String categoryName
static constraints = {
name nullable: false, blank: false, unique: true
}
}
首先,我需要一个Spec作为基础。此基础将具有ProductSpec和Category Spec的常见测试。
@Mock([Product, Category]) //? is this needed
class BaseSpec extends Specification {
@Shared classForTest
@Shared constructor
@Shared nameParam
def setup(){
//This is what I would override in my child Tests
//classForTest = new Category().getClass()
//constructor = classForTest.getConstructor()
//nameParam = "categoryName"
}
def "Testing that the name field is unique"(){
given: "A class instance"
String testValue = "ABSCSD SDS SDS"
def instance1 = constructor.newInstance() //using the constructor to get an instance
instance1."${nameParam}" = testValue
instance1.save(flush: true, failOnError: true)
and: "A duplicated Instance"
def instance2 = constructor.newInstance()
instance2."${nameParam}" = testValue
expect: "The second instance should not save"
shouldFail {instance2.save(flush: true, failOnError: true)}
}
//...Other common test cases
}
然后我会有一个ProductSpec和一个CategorySpec,每个应该只覆盖BaseSpec的设置。
@TestFor(Product)
class ProductSpec extends BaseSpec{
@Override
def setup(){
classForTest = new Product().getClass() //Get the class that is testec
constructor = classForTest.getConstructor() //Get the constructor of the tested class
nameParam = "productName" //Establish the name of the parameter
}
//... Other Product Tests
}
@TestFor(Category)
class CategorySpec extends BaseSpec {
@Override
def setup(){
classForTest = new Category().getClass()
constructor = classForTest.getConstructor()
nameParam = "categoryName"
}
//... Other Category Tests
}
答案 0 :(得分:0)
这是我最初发布的内容的替代方案。 它不使用继承,但它允许测试用例非常相似的测试用例。
Consider the domain classes
class Product{
String productName
static constraints = {
name nullable: false, blank: false, unique: true
}
}
class Category{
String categoryName
static constraints = {
name nullable: false, blank: false, unique: true
}
}
作为一个非常简单的例子,我们想测试productName和categoryName的验证。所以我们可以进行如下测试:
@Mock([Product, Category])
class CatalogSimpleGenericSpec extends Specification {
def "Validation of test field in a given domain"(){
given: "A new instance of the domain"
def testInstance = constructorOfInstance.newInstance() //Creating the instance using the constructor
testInstance."${fieldName}" = fieldValue
testInstance.validate()
expect: "Testing if the instance should save depending on the value of shouldHaveErrors"
assert testInstance.hasErrors() == shouldHaveErrors //Verifying if it should have errors
//If there are errors the instance should fail to save, otherwise it will save perfectly
shouldHaveErrors ?
shouldFail {testInstance.save(flush: true, failOnError: true)}
: testInstance.save(flush: true, failOnError: true)
where:
constructorOfInstance | shouldHaveErrors | fieldName | fieldValue | reasoning
//----------------- PRODUCT ----------------------
new Product().getClass().getConstructor() | false | "productName" | "Folders" | "Should pass since a product name is supplied"
new Product().getClass().getConstructor() | true | "productName" | "" | "Should fail empty strings should not be accepted"
new Product().getClass().getConstructor() | true | "productName" | null | "Should fail null values shoult not be accepted"
//----------------- CATEGORY --------------------
new Category().getClass().getConstructor() | false | "categoryName" | "Office Supplies" | "Should pass since a category name is supplied"
new Category().getClass().getConstructor() | true | "categoryName" | "" | "Should fail empty strings should not be accepted"
new Category().getClass().getConstructor() | true | "categoryName" | null | "Should fail null values shoult not be accepted"
}
}
我没有使用继承,而是获取域实例的构造函数,然后使用该构造函数(constructorOfInstance)来构建我的实例(testInstance)。字段值使用testInstance."${fieldName}" = fieldValue
指定。我们使用 shouldHaveErrors 的值测试保存是否会失败。
