Introduced This document will be a "high-level" principle of how to use Robotframework to write good test cases. The details of how to use robotframework to interact with your test system are not included in this document. The most important rule is to ensure that the test case is People who are familiar with this field are as simple as possible.

When talking about use cases, many people may be familiar with them, but many will not actually use them. Next, based on the accumulation and reading of books over a period of time, we will summarize the following, which will inevitably lead to errors. We also hope to criticize and correct the mistakes and make progress together.

Redis is a high-performance key-value database. The emergence of redis largely compensates for the shortage of keyvalue storage such as memcached, and can play a very good complementary role in relational databases. It provides Python, Ruby, Erlang, PHP, and Java clients for ease of use.Redis uses a single-thread IO multiplexing model and encapsulates a simple AeEvent event processing framework, which mainl
