Robot Framework 的数据驱动场景

Question

我想在变量文件中设置用户名和密码，当测试通过每个用户名时，它会前进到下一行数据。

我正在使用资源文件来驱动数据，我的初始 FOR 脚本处理用户名 1 (eeny)，然后嵌套的 FOR 循环一次传递所有密码。

*** Variables  ***
@{users}  eeny  meeny  miny  moe
@{pwds}  pwd  pwd1  pwd2  pwd3

*** Test Cases ***

Login Test
    :FOR    ${u}    IN    @{users}
    \   Open Browser  ${URL}
    \   set window size  1440  900
    \   set selenium speed  .5
    \   input text  id=username  ${u}
    \   :FOR  ${p}  IN  @{pwds}
    \   \  input text  id=password  ${p}
    \   \  click button  css=button.primary
    \   \  wait until page contains  css=p.logout
    \   \  capture page screenshot
    \   \  click element  css=p.logout

目前我正在尝试嵌套 FOR 语句，或同时声明用户名和密码变量的 FOR 语句，但不反对更改获取数据的策略并使用多维数组或类似的方法效果更好。

Answer 1

我认为您对单个测试用例和多个测试用例有误解。您上面的内容将输入一个用户名，然后它将通过一个密码循环，提交和注销。只有当你碰巧在下一页有相同的元素时，它才会尝试输入另一个密码。

我建议看看这里：http://robotframework.org/robotframework/latest/RobotFrameworkUserGuide.html#data-driven-style

另外看看一些类似的问题，你需要提供一个测试模板，我的建议是当你让它在两个测试用例工作时担心循环。

数据驱动测试可以通过“通过测试模板驱动的数据”或从 Excel 或 csv 读取数据来实现。

“通过测试模板驱动的数据”
在此我们将创建一个用户定义的关键字，它只是我们想要多次执行的函数或源代码。 我们在Settings 部分声明为'Test Template'。
当我们给 TestCase 名字加上 arguments 时，它每次都会执行Test Template。
这里是示例代码
