Question

我想阅读一个excel文件，所以我在机器人框架中写了这些关键字：

*** Settings ***
Library     ExcelLibrary
Library     Collections

Resource    ../Variables/ConstantVariables.robot
Resource    ../Variables/ConfigVariables.robot

*** Variables ***


*** Keywords ***
Read Data From Excel
    [Arguments]     ${filename}    ${sheetname}
    open excel      ${filename}
    @{excel_result} =   Create List
    ${rows} =   get_row_count   ${sheetname}
    :FOR    ${rindex}   IN RANGE    1   ${rows}
    \   ${ret_val} =      Get Row Values     ${sheetname}    ${rindex}
    \    Append To List      ${excel_result}    ${ret_val}

    [Return]    ${excel_result}

Get All Values of the Row
    [Arguments]     ${sheetname}    ${rowindex}
    ${cols} =   get_column_count   ${sheetname}
    ${vals} =   Create Dictionary
    ${titles} =     get_row_values      ${sheetname}    0
    :FOR    ${cindex}   IN RANGE    0   ${cols}
    \    ${val} =    read_cell_data_by_coordinates       ${sheetname}       ${cindex}        ${rowindex}
    \    Set To Dictionary   ${vals}    ${titles[0]}     ${val}

    [Return]    ${vals}

这是方案文件：

*** Settings ***
Resource    ../Variables/ConstantVariables.robot
Resource    ../Variables/ConfigVariables.robot
Resource    ../Keywords/CommonKeywords.robot

*** Test Cases ***
Test For Loop
    @{ret_val} =    Read Data From Excel    ${jobfilename}      ${jobsheetname}
    log to console      ${ret_val}

这是我得到的输出：

PS D:\Abbasimazar\workspace\RobotTests\Scenarios> pybot .\scenario.robot
==============================================================================
Scenario
==============================================================================
Test For Loop                                                         .[[('A2', u't1'), ('B2', u'n1'), ('C2', u'c1')], [
('A3', u't2'), ('B3', u'n2'), ('C3', u'c2')], [('A4', u't3'), ('B4', u'n3'), ('C4', u'c3')]]
Test For Loop                                                         | PASS |
------------------------------------------------------------------------------
Scenario                                                              | PASS |
1 critical test, 1 passed, 0 failed
1 test total, 1 passed, 0 failed
==============================================================================
Output:  D:\Abbasimazar\workspace\RobotTests\Scenarios\output.xml
Log:     D:\Abbasimazar\workspace\RobotTests\Scenarios\log.html
Report:  D:\Abbasimazar\workspace\RobotTests\Scenarios\report.html

但我希望得到这个：

[{'A2': u't1', 'B2': u'n1', 'C2': u'c1'}, {'A3': u't2', 'B3': u'n2', 'C3': u'c2'}, {'A4': u't3', 'B4': u'n3', 'C4': u'c3'}]

任何想法我做错了什么？

编辑1：

正如@ ombre42所说，调用关键字时出错。我应该换行：

${ret_val} =      Get Row Values     ${sheetname}    ${rindex}

成：

${ret_val} =      Get All Values of the Row     ${sheetname}    ${rindex}

但在那之后我注意到了这一行

${titles} =     get_row_values      ${sheetname}    0

给了我这个：

==============================================================================
Scenario
==============================================================================
Test For Loop                                                         .[{('A1', u'test'): u'c1'}, {('A1', u'test'): u'c2
'}, {('A1', u'test'): u'c3'}]
Test For Loop                                                         | PASS |
------------------------------------------------------------------------------
Scenario                                                              | PASS |
1 critical test, 1 passed, 0 failed
1 test total, 1 passed, 0 failed
==============================================================================

所以我写了新方法来获得标题：

Get Titles From Sheet
    [Arguments]     ${sheetname}
    ${cols} =   get_column_count   ${sheetname}
    @{titles} =   Create List
    :FOR    ${cindex}   IN RANGE    0   ${cols}
    \    ${val} =    read_cell_data_by_coordinates       ${sheetname}       ${cindex}        0
    \    Append To List      ${titles}    ${val}

    [Return]    ${titles}

并将该行更改为：

${titles} =     Get Titles From Sheet      ${sheetname}

现在结果是我想要的：

==============================================================================
Scenario
==============================================================================
Test For Loop                                                         .[{u'test': u't1', u'name': u'n1', u'class': u'c1'
}, {u'test': u't2', u'name': u'n2', u'class': u'c2'}, {u'test': u't3', u'name': u'n3', u'class': u'c3'}]
Test For Loop                                                         | PASS |
------------------------------------------------------------------------------
Scenario                                                              | PASS |
1 critical test, 1 passed, 0 failed
1 test total, 1 passed, 0 failed

Answer 1

从Excel读取数据调用获取行值而不是获取行的所有值，这将创建字典。 获取行的所有值未在提供的代码中使用。

也许您认为从Excel读取数据正在使用您的用户关键字，而实际上它正在使用库关键字。

Answer 2

也许是OrderedDict？ OrderedDicts表示看起来像元组列表：

>>> from collections import OrderedDict
>>> d = OrderedDict()
>>> d['x'] = 1
>>> d
OrderedDict([('x', 1)])

即使它是元组的常规列表而不是OrderedDict，将它们转换为dict也是微不足道的，因为dict构造函数可以直接获取元组列表：

>>> dict([('x', 1)])
{'x': 1}

我在机器人框架中得到了元组列表而不是字典
