When to use the global or a local data table?51Testing软件测试网9N-XAbtk

3i!pW/zb+e8P0It is important to understand in what situations the global or a local data table should be used.
/^2hKzz-{$J0Consider the following two scenarios

Scenario 1 - Log into the application, book 1 ticket, log out. Repeat the scenario for many users51Testing软件测试网#{r$x [kbE5n0s

什么时候用global数据表,什么时候用local数据表?51Testing软件测试网Ddr,A*\;`

理解什么时候用global数据表什么时候用local数据表是很重要的,我们认真考虑以下两种不同的场景51Testing软件测试网B5H~%S&?

场景1:登录系统,订一张票,退出.不同的用户,多次重复这个场景.

场景2:登录系统,订3张票,退出.51Testing软件测试网@p6eTV:U?U

]Tq'zS/l8E7A"WQI0在参数表里面有username,password,tickets的详细信息,并且我们执行这个场景是是单个action或多个actions (Login, booking and logout)时,使用global数据表更加适应于场景1

我的理解:连贯动作,多用户单操作时适用global

local数据表更加适合于这种场景. 测试action被划分为三个步骤,即login,booking and logout.login和logout可以使用global表中的参数,booking可以使用local表中详细的tickets数据,并且期望booking这个action可以执行local中所有的数据

gf0我的理解:单用户,多操作时适用local,重复执行主操作.与loadrunner中,init(),Action(),end()类似
