用TypeORM进行Jest测试

Question

我想让Jest和TypeORM博览会-范例项目一起工作

我已经做了很多工作，想要让ts和世博玩笑都能工作。我遵循了取笑和博览小丑的官方指南。我能够在一个新的空项目(不是TypeORM示例)中展示博览-Jest按预期工作，但是当我将这些更改应用到TypeORM博览会项目时，它遇到了一些问题。

我想博览会更好。从TypeORM博览会的一个干净的克隆开始可能会更容易一些--比如回购。

我已经将package.json编辑成了一个版本，如果它是一个更简单的起点，就不应该出现依赖问题。(笑话可以修改或删除，以支持单独的配置)

我也有同样的问题，我的问题是当我尝试测试getConnection() typeorm函数或DataSource({.}).initialize()的返回时出错。为了使它工作，我使用slite3库，而不是博览.所以它起作用，参见：https://github.com/EmanuelVogt/expo-sqlite-typeorm-jest
