在TeamCity中更改app.config中的值

Question

在包含所有单元测试的Visual Studio解决方案中,我们有一些文本文件.根据我们的单元测试生成的一些结果检查这些文本文件.

为了加载文件,我们有一个app.config:

 <appSettings>
    <add key="BaseTestDataPath" value="D:\MyPath\MySolution\" />
 </appSettings>

在每次构建运行的TeamCity中,我想:

将BaseTestsDataPath更改为代理的特定工作路径,例如.

C:\TeamCity\buildAgent\work\1ca1a73fe3dadf57\MySolution\

我知道代理工作文件夹中的物理布局,所以我需要知道的是:

• 如何在针对TeamCity的构建步骤中针对解决方案运行Nunit之前更改app.config文件

Answer 1

有几种方法可以解决这个问题.

在运行NUnit步骤之前,只需选择以下脚本之一,将其添加到源代码控制并在构建配置中设置PowerShell构建运行器,以运行传递所需参数的脚本.如果选择选项2,那么您还需要考虑转换dll.

AppSettingReplace.ps1

如果您只想更改单个值,可以使用一些简单的PowerShell实现此目的,该PowerShell将配置文件加载到xml文档中,迭代应用程序设置并更改匹配的设置.

    Write-Host

    try {
        $xml = [xml](get-content($ConfigurationFile))
        $conf = $xml.configuration
        $conf.appSettings.add | foreach { if ($_.key -eq $ApplicationSetting) { $_.value = $ApplicationSettingValue } }
        $xml.Save($ConfigurationFile)
    } 
    catch [System.Exception] {
        Write-Output $_
        Exit 1
    }

    Write-Host "================== Config Transform - Version"$CurrentScriptVersion": END =================="
}

function Log-Variables
{
    Write-Host "ConfigurationFile: " $ConfigurationFile
    Write-Host "ApplicationSetting: " $ApplicationSetting
    Write-Host "ApplicationSettingValue: " $ApplicationSettingValue
    Write-Host "Computername:" (gc env:computername)
}

Main

用法

AppSettingReplace.ps1"D:\ MyPath\app.config""BaseTestDataPath""%teamcity.build.workingDir%"

XdtConfigTransform.ps1

另一种方法是使用XDT提供完整的配置转换支持 - 这确实需要Microsoft.Web.XmlTransform.dll以某种方式在服务器上结束(我通常将其放入源代码控制中).

以下脚本将使用另一个配置文件转换一个配置文件.

# Xdt Config Transform

# Script Input Parameters
param (
    [ValidateNotNullOrEmpty()]
    [string] $ConfigurationFile = $(throw "-ConfigurationFile is mandatory, please provide a value."),
    [ValidateNotNullOrEmpty()]
    [string] $TransformFile = $(throw "-TransformFile is mandatory, please provide a value."),
    [ValidateNotNullOrEmpty()]
    [string] $LibraryPath = $(throw "-LibraryPath is mandatory, please provide a value.")
)

function Main() 
{
    $CurrentScriptVersion = "1.0"

    Write-Host "================== Xdt Config Transform - Version"$CurrentScriptVersion": START =================="

    # Log input variables passed in
    Log-Variables
    Write-Host

    if (!$ConfigurationFile -or !(Test-Path -path $ConfigurationFile -PathType Leaf)) {
        throw "File not found. $ConfigurationFile";
        Exit 1
    }
    if (!$TransformFile -or !(Test-Path -path $TransformFile -PathType Leaf)) {
        throw "File not found. $TransformFile";
        Exit 1
    }

    try {

        Add-Type -LiteralPath "$LibraryPath\Microsoft.Web.XmlTransform.dll"
        $xml = New-Object Microsoft.Web.XmlTransform.XmlTransformableDocument;
        $xml.PreserveWhitespace = $true
        $xml.Load($ConfigurationFile);

        $xmlTransform = New-Object Microsoft.Web.XmlTransform.XmlTransformation($TransformFile);
        if ($xmlTransform.Apply($xml) -eq $false)
        {
            throw "Transformation failed."
        }
        $xml.Save($ConfigurationFile)
    } 
    catch [System.Exception] {
        Write-Output $_
        Exit 1
    }

    Write-Host "================== Xdt Config Transform - Version"$CurrentScriptVersion": END =================="
}

    Write-Host "TransformFile: " $TransformFile

    Write-Host "Computername:" (gc env:computername)
}

Main

用法

XdtConfigTransform.ps1"D:\ MyPath\app.config""D:\ MyPath\app.transform.config""%teamcity.build.workingDir%\ Library"

注意:最后一个参数是包含Microsoft.Web.XmlTransform.dll的目录的路径
