PHP单元测试脏数据处理方式
单元测试的时候,难免产生脏数据,对脏数据该如何处理呢? 我们最先想到的方法是: 在测试方法中, 被删 /改,操作之前记录数据,操作完成后还原数据。 新增 ,记录新增的主键,测试结束后在测试脚本中执行删除。 我之前想了很多种想取巧的方法,想让操作更
单元测试的时候,难免产生脏数据,对脏数据该如何处理呢?
我们最先想到的方法是:
在测试方法中,
被删 /改,操作之前记录数据,操作完成后还原数据。
新增 ,记录新增的主键,测试结束后在测试脚本中执行删除。
我之前想了很多种想取巧的方法,想让操作更简单,但是都不够完美,有的甚至非常差。
1、在数据层添加观察者,数据有变动后通知观察者来处理。
这样不但有些变动可能被遗漏,还打破了程序的结构,需要重新设计数据层,不可行。
2、使用临时表
在setUp()中创建临时表并绑定到表网关类,tearDown()中将其临时表删除。
这样当一个测试类中需要调用到多个表网关类的时候,就要弄n个表网关类并将其绑到模型中,灾难啊。
回到头来,还是用首先想到的方法更好。

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
