Robotframework 数据驱动程序库无法从 CSV 文件中找到变量

Question

我在尝试使用机器人框架设置数据驱动程序库时遇到问题。我收到错误消息，未找到其中一个变量。

CSV 文件：

${username},${password}
admin@yourstore.com,adm
adm@yourstore.com,admin
adm1@yourstore.com,adm

DDT2_csv.robot:

*** Settings ***
Library     SeleniumLibrary
Library     DataDriver  ../testdata/TestData.csv    delimiter=,     encoding=utf-8
Resource    ../resources/login_resources.robot
Suite Setup     login_resources.open my browser
Suite Teardown  login_resources.close browsers
Test Template   Invalid Login


*** Test Cases ***
Doing Test Credentials for ${username} and ${password}  Default    UserData

*** Keywords ***
Invalid Login 
    [Arguments]     ${username}     ${password}
    input email  ${username}
    input password  ${password}
    click login button
    error message should be visible

我收到以下错误：

谁能帮帮我？

我不是这个库的专家，但在我看来，分隔符 arg 被默认方言设置覆盖，并保留为“;”即使您尝试覆盖。

可能值得尝试 arg dialect=excel，因为它默认为“,”定界符

示例：

*** Settings ***
Library     SeleniumLibrary
Library     DataDriver  ../testdata/TestData.csv     dialect=excel    encoding=utf-8
Resource    ../resources/login_resources.robot
Suite Setup     login_resources.open my browser
Suite Teardown  login_resources.close browsers
Test Template   Invalid Login

*** Test Cases ***
Doing Test Credentials for ${username} and ${password}  Default    UserData

*** Keywords ***
Invalid Login 
    [Arguments]     ${username}     ${password}
    log to console  ${username}
    log to console  ${password}

您的 csv 中可能还需要 *** Test Cases *** 列，因为我认为这是必填列，如下所示：

*** Test Cases ***,${username},${password}
Case1,admin@yourstore.com,adm
Case2,adm@yourstore.com,admin
Case3,adm1@yourstore.com,adm
