- 針對Robot的開發規則說明
- Library(Implement Code)
- Class-base
- Module-base
:::info
:question: 比較各種Implement Code的寫法？
:::
- Task
- For other automation purposes instead of test automation (e.g. robotic process automation, RPA)
- sysntax與Test Case相同
| | Test Cases | Tasks |
| ------- |:------------------:|:-------------------------:|
| Purpose | test automation | RPA or general automation |
| Section | *** Test Cases *** | *** Tasks *** |
| Syntax | same as Tasks | same as Test Cases |
- 常與[RPA Framework](https://rpaframework.org/)的library一起使用
- 條件式和迴圈
- 若以「Readability」做為測項撰寫原則
- ==Test Cases中盡量避免使用==
- 建議使用在Keywords中(Resource/Library)
- 邏輯仿造Python，但改成Robotframework的Syntax
- For Loop常與 `RANGE`, `ENUMERATE`, `ZIP`合用
- Test TimeOut
- Under `Setting`, a test case or user keyword`
- Input Value:
- 沒有timeout: `NONE`, 0 , negative number
- Use time format
- days, day, d
- hours, hour, h
- minutes, minute, mins, min, m
- seconds, second, secs, sec, s (default units)
- milliseconds, millisecond, millis, ms

            1 day 2 hours 3 minutes 4 seconds 5 milliseconds
            1d 2h 3m 4s 5ms
            10
            10 s

- timer string
- hh\:mm\:ss.mil
- Evaluate: 將string視為python script執行，並將執行過的值回傳。
- In line `{}` 搭配 `${}` `@{}` `&{}`

        ${{'positive' if ${x} > 0 else 'negative'}}

- keyword `Evalute` 搭配 `${}` `@{}` `&{}`

        ${type} =    Evaluate    'positive' if ${x} > 0 else 'negative'

:::info
:question: 可不可以直接在Test Case或User Keyword中直接使用python的syntax？
:bulb: 用`Evalute`就可以，但*為什麼需要？*
