robot framework学习笔记之七—连接mysql数据库

1.安装Database-Library

输入命令：pip install robotframework_databaselibrary

2.添加Database的Library

    3.实例

*** Test Cases ***
查询单条数据
    ${data}    create dictionary    shopCode=xxx    coordinate=
    ${response}    Rest.Get    /api/shop/current.json    ${data}    form    ${hosts["weidian"]}
    Connect To Database Using Custom Params    pymysql    host='115.29.xx.xxx', port=3306, user='xx', passwd='xxx', db='test', charset= 'utf8'
    ${name}    query    select nickname from authshop where code='xxx'
    log    ${response["data"]["shop"]["shopName"]}
    should be equal    ${response['data']['shop']['shopName']}    ${name[0][0]}
    log    ${name[0][0]}

查询多条数据

数据库中存在
    #Check If Exists In Database
    ${data}    create dictionary    shopCode=xxx    coordinate=
    ${response}    Rest.Get    /api/shop/current.json    ${data}    form    ${hosts["weidian"]}
    Connect To Database Using Custom Params    pymysql    host='115.29.xx.xx', port=3306, user='test', passwd='xxx', db='test', charset= 'utf8'
    Check If Exists In Database    select nickname from authshop where code='xxx'

数据库中不存在
    #Check If Not Exists In Database
    ${data}    create dictionary    shopCode=xxx    coordinate=
    ${response}    Rest.Get    /api/shop/current.json    ${data}    form    ${hosts["weidian"]}
    Connect To Database Using Custom Params    pymysql    host='115.29.xx.xxx', port=3306, user='xx', passwd='xx', db='test', charset= 'utf8'
    Check If Exists In Database    select nickname from authshop where code='xxx'

查询
    #Description
    ${data}    create dictionary    shopCode=xxx    coordinate=
    ${response}    Rest.Get    /api/shop/current.json    ${data}    form    ${hosts["weidian"]}
    Connect To Database Using Custom Params    pymysql    host='115.29.xx.xxx', port=3306, user='xxx', passwd='xxx', db='test', charset= 'utf8'
    ${qeeryResults}    query    select nickname from authshop where code='xxx'
    log    ${qeeryResults}

返回查询结果总行数
#Row Count
    ${data}    create dictionary    shopCode=xxx    coordinate=
    ${response}    Rest.Get    /api/shop/current.json    ${data}    form    ${hosts["weidian"]}
    Connect To Database Using Custom Params    pymysql    host='115.29.xx.xxx', port=3306, user='xxx', passwd='xxx', db='xxx', charset= 'utf8'
    ${qeeryResults}    row count    select shop_code from authshop_relation where site_id=''
    log    ${qeeryResults}

 4.api详情

API	参数	说明
Check If Exists In Database	查询语句	数据库中存在：存在，则为PASS，不存在，则为FAIL
Check If Not Exists In Database	查询语句	数据库中不存在：不存在，则为PASS，存在，则为FAIL
Connect To Database	dbapiModuleName=None, dbName=None, dbUsername=None, dbPassword=None, dbHost=localhost, dbPort=5432, dbConfigFile=./resources/db.cfg	连接数据库配制信息，通过配制各项属性完成
Connect To Database Using Custom Params	dbapiModuleName=None, db_connect_string=	连接数据库配制信息，通过db_connect_string来传递。如database='my_db_test', user='postgres', password='s3cr3t', host='tiger.foobar.com', port=5432
Delete All Rows From Table	表名	删除数据库中表的所有行：删除成功，则PASS；失败，则Fail
Description	查询语句	返回查询语句的结果，内容格式为： [Column(name='id', type_code=1043, display_size=None, internal_size=255, precision=None, scale=None, null_ok=None)] [Column(name='first_name', type_code=1043, display_size=None, internal_size=255, precision=None, scale=None, null_ok=None)] [Column(name='last_name', type_code=1043, display_size=None, internal_size=255, precision=None, scale=None, null_ok=None)]
Disconnect From Database	无	断开数据库链接
Execute Sql Script	SqlScriptFileName	执行脚本文件。SqlScriptFileName物理路径＋FileName。
Execute Sql String	SqlString	执行Sql语句
Query	查询语句	返回查询语句的查询结果
Row Count	查询语句	返回查询语句的查询结果行总数
Row Count Is 0	查询语句	查询语句的查询结果行总数：为0,则PASS;非0,则FAIL
Row Count Is Equal To X	查询语句，X	查询语句的查询结果行总数：为X,则PASS;非X，则FAIL X，为预期的查询结果行数，第二个需要传递的参数
Row Count Is Greater Than X	查询语句，X	查询语句的查询结果行总数：大于X,则PASS;小于或等于X，则FAIL X，为预期的查询结果行数，第二个需要传递的参数
Row Count Is Less Than X	查询语句，X	查询语句的查询结果行总数：大于X,则PASS;小于或等于X，则FAIL X，为预期的查询结果行数，第二个需要传递的参数
Table Must Exist	表名	表名必须存在：存在，则PASS；不存在，则FAIL

5.实例二

    #Connect To Database Using Custom Params:使用参数来连接数据库    pymysql：连接的数据库     charset=‘utf8’解决中文显示成？？？的问题
    Connect To Database Using Custom Params    pymysql    host=‘115.29.10.xxx’, port=3306, user=‘xxx’, passwd=‘xxx’, db=‘xxx’,charset=‘utf8’
    #使用Query方法来执行"select name from wx_account_detail where type=0”，并将查询的结果返回对变量@{name}
    @{name}    query    select name from wx_account_detail where type=0
    #循环获取多条记录的值，并打印
    : FOR    ${i}    IN RANGE    0    len(@{name})
    \    log    @{name}[${i}]
