In the past, developer of Apache Doris send pull request and wait for regression testing, which is execute in Baidu internally. There are some problem: 1. test case is not shared to developer. so we can not quickly accumulate test case to ensure the stable of Apache Doris 2. waiting too long. if test failed, developer must change code and wait again
So, I implement a scalable regression testing framework(in pull request #8125). Developer can run regression testing in local enviroment, and contribute more test case. In order to readable, writeable, normalization and scalable, I use groovy to implement a DSL which named Action, developer can use Action to write various test case, for example 1. sql action can execute a sql 2. qt action can execute sql and compare result to tsv file 3. stream load action can load data to doris 4. explain action can check query plan welcome to contribute test case, improvement test framework, and update document.
