我正在尝试在我的单元测试中测试异常的抛出。我试图对 delete 方法进行元分类,但它不想坚持。你能从代码中看出我做错了什么吗?

单元测试代码:

@TestFor(ProductController)
@TestMixin(DomainClassUnitTestMixin)
class ProductControllerTests {     
  void testDeleteWithException() {
    mockDomain(Product, [[id: 1, name: "Test Product"]])
    Product.metaClass.delete = {-> throw new DataIntegrityViolationException("I'm an       exception")}
    controller.delete(1)
    assertEquals(view, '/show/edit')
}

控制器动作代码:

def delete(Long id) {
    def productInstance = Product.get(id)
    if (!productInstance) {
        flash.message = message(code: 'default.not.found.message', args: [message(code: 'product.label', default: 'Product'), id])
        redirect(action: "list")
        return
    }

    try {
        productInstance.delete(flush: true)
        flash.message = message(code: 'default.deleted.message', args: [message(code: 'product.label', default: 'Product'), id])
        redirect(action: "list")
    }
    catch (DataIntegrityViolationException e) {
        flash.message = message(code: 'default.not.deleted.message', args: [message(code: 'product.label', default: 'Product'), id])
        redirect(action: "show", id: id)
    }
}    

当我运行测试时,productInstance.delete(flush: true)不会抛出我期望的异常。相反,它重定向到action: "list". 有谁知道如何覆盖 Product.delete() 方法以便我可以强制异常?

您正在嘲笑delete没有任何参数,但您的控制器调用delete(flush: true). 尝试delete(Map)像这样模拟:

Product.metaClass.delete = { Map params -> 
    throw new DataIntegrityViolationException("...")
}
