# 新加case注意事项
|
|
|
|
1. 变量名前要写 def，否则是全局变量，并行跑的 case 的时候可能被其他 case 影响。
|
|
|
|
Problematic code:
|
|
```
|
|
ret = ***
|
|
```
|
|
Correct code:
|
|
```
|
|
def ret = ***
|
|
```
|
|
2. 尽量不要在 case 中 global 的设置 session variable，或者修改集群配置，可能会影响其他 case。
|
|
|
|
Problematic code:
|
|
```
|
|
sql """set global enable_pipeline_x_engine=true;"""
|
|
```
|
|
Correct code:
|
|
```
|
|
sql """set enable_pipeline_x_engine=true;"""
|
|
```
|
|
3. 如果必须要设置 global，或者要改集群配置，可以指定 case 以 nonConcurrent 的方式运行。
|
|
|
|
[示例](https://github.com/apache/doris/blob/master/regression-test/suites/query_p0/sql_functions/cast_function/test_cast_string_to_array.groovy#L18)
|
|
4. case 中涉及时间相关的，最好固定时间，不要用类似 now() 函数这种动态值，避免过一段时间后 case 就跑不过了。
|
|
|
|
Problematic code:
|
|
```
|
|
sql """select count(*) from table where created < now();"""
|
|
```
|
|
Correct code:
|
|
```
|
|
sql """select count(*) from table where created < '2023-11-13';"""
|
|
```
|
|
5. case 中 streamload 后请加上 sync 一下，避免在多 FE 环境中执行不稳定。
|
|
|
|
Problematic code:
|
|
```
|
|
streamLoad { ... }
|
|
sql """select count(*) from table """
|
|
```
|
|
Correct code:
|
|
```
|
|
streamLoad { ... }
|
|
sql """sync"""
|
|
sql """select count(*) from table """
|
|
```
