我是否必须在每个TestCase中创建我的测试数据库条目？(Do I have to create my test database entries in each TestCase?)

 我有一个电子商务应用程序，我有子应用程序，如product ， order ， checkout等。 在每个应用程序中，我都有一个tests.py文件，其中包含对该应用程序的隔离部分的测试。 
 
 许多不同的测试用例/子应用程序使用相同类型的数据。 例如，产品测试，订单测试和结账测试都需要包含产品，购物车，货币等的样本数据。 
 
 目前我正在每个TestCase的setUp函数中创建此测试数据。 但这意味着我一遍又一遍地创建相同的数据，这看起来非常愚蠢和不必要。 
 
 我有什么方法可以为我的测试数据库创建“全局”测试数据吗？ 在运行任何TestCase之前，这将首先创建？ 或者我已经做了“正确”的方式，即使它看起来很糟糕？ 
 
 我正在使用Django，它正在使用unittest python模块。 

I have a ecommerce application where I have sub-applications such as product, order, checkout and so on. In each application I have a tests.py file containing test for that isolated part of the app.
 
Many of the different testcases/sub-apps use the same kind of data. For example, both product-tests, order-tests and checkout-tests need to have sample data for products, carts, currencies and so on.
 
Currently I'm creating this test data in the setUp function of each TestCase. But this means that I'm creating the same data over and over again, which seem very stupid and unnecessary.
 
Is there some way for me to create "global" test data for my test-database? That will be created first, before any TestCase is run? Or am I already doing the "correct" way, even though it seems bad?
 
I'm using Django, which is using the unittest python module.
