unit-testing - 什么时候测试不是单元测试？

Question

我正在寻找如下规则:

如果满足以下条件，则测试不是单元测试:

• 它与数据库通信
• 它不能与其他测试并行运行
• 使用注册表或文件系统等“环境”

还有什么？

Answer 1

参见Michael Feathers' definition

A test is not a unit test if:

• It talks to the database
• It communicates across the network
• It touches the file system
• It can't run at the same time as any of your other unit tests
• You have to do special things to your environment (such as editing config files) to run it.
