<#
Note on Resolve-Path:
All paths are sent through Resolve-Path/Resolve-PSFPath in order to convert them to the correct path separator.
This allows ignoring path separators throughout the import sequence, which could otherwise cause trouble depending on OS.
Resolve-Path can only be used for paths that already exist, Resolve-PSFPath can accept that the last leaf my not exist.
This is important when testing for paths.

    .SYNOPSIS
        Create the basic tests for the database project

    .DESCRIPTION
        The script will connect to a database on a SQL Server instance, iterate through objects and create tests for the objects.

        The script will create the following tests
        - Test if the database settings (i.e. collation) are correct
        - Test if an object (Function, Procedure, Table, View etc) exists
        - Test if an object (Function or Procedure) has the correct parameters
        - Test if an object (Table or View) has the correct columns

        Each object and each test will be it's own file.

   .PARAMETER SqlInstance
        The target SQL Server instance or instances. Server version must be SQL Server version 2012 or higher.

        This should be the primary replica.

    .PARAMETER SqlCredential
        Login to the target instance using alternative credentials. Accepts PowerShell credentials (Get-Credential).

        Windows Authentication, SQL Server Authentication, Active Directory - Password, and Active Directory - Integrated are all supported.

        For MFA support, please use Connect-DbaInstance.

    .PARAMETER Database
        The database or databases to add.

    .PARAMETER OutputPath
        Folder where the files should be written to

    .PARAMETER Creator
        The person that created the tests. By default the command will get the environment username

    .PARAMETER TemplateFolder
        The template folder containing all the templates for the tests.
        By default it will use the internal templates directory

    .PARAMETER Schema
        Filter the functions based on schema

    .PARAMETER Function
        Filter out specific functions that should only be processed

    .PARAMETER Procedure
        Filter out specific procedures that should only be processed

    .PARAMETER Table
        Filter out specific tables that should only be processed

    .PARAMETER Index
        Filter out specific indexes that should be processed

    .PARAMETER View
        Filter out specific views that should only be processed

    .PARAMETER SkipDatabaseTests
        Skip the database tests

    .PARAMETER SkipFunctionTests
        Skip the function tests

    .PARAMETER SkipProcedureTests
        Skip the procedure tests

    .PARAMETER SkipTableTests
        Skip the table tests

    .PARAMETER SkipViewTests
        Skip the view tests

    .PARAMETER SkipIndexTests
        Skip the view tests

    .PARAMETER TestClass
        Test class name to use for the test

    .PARAMETER WhatIf
        Shows what would happen if the command were to run. No actions are actually performed.

    .PARAMETER Confirm
        Prompts you for confirmation before executing any changing operations within the command.

    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

    .EXAMPLE
        PS C:\> Invoke-PSTGTestGenerator -SqlInstance SQLDB1 -Database DB1 -OutputPath c:\projects\DB1\DB1-Tests\TestBasic

        Iterate through all the objects and output the files to "c:\projects\DB1\DB1-Tests\TestBasic"

    .EXAMPLE
        PS C:\> Invoke-PSTGTestGenerator -SqlInstance SQLDB1 -Database DB1 -OutputPath c:\projects\DB1\DB1-Tests\TestBasic -Procedure Proc1, Proc2

        Iterate through all the objects but only do "Proc1" and "Proc2" for the procedures.

        NOTE! All other tests like the table, function and view tests will still be generated

    .EXAMPLE
        PS C:\> Invoke-PSTGTestGenerator -SqlInstance SQLDB1 -Database DB1 -OutputPath c:\projects\DB1\DB1-Tests\TestBasic -SkipProcedureTests

        Iterate through all the objects but do not process the procedures

        Login to the target instance using alternative credentials. Accepts PowerShell credentials (Get-Credential).

        The database or databases to add.

    .PARAMETER OutputPath
        Path to output the test to

    .PARAMETER Creator
        The person that created the tests. By default the command will get the environment username

    .PARAMETER TemplateFolder
        Path to template folder. By default the internal templates folder will be used

    .PARAMETER TestClass
        Test class name to use for the test

    .PARAMETER WhatIf
        Shows what would happen if the command were to run. No actions are actually performed.

    .PARAMETER Confirm
        Prompts you for confirmation before executing any changing operations within the command.

        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

    <#
    .SYNOPSIS
        Function to check if an object exists

    .DESCRIPTION
        The function will create a test to check for the existence of an object

    .PARAMETER SqlInstance
        The target SQL Server instance or instances. Server version must be SQL Server version 2012 or higher.

    .PARAMETER SqlCredential
        Login to the target instance using alternative credentials. Accepts PowerShell credentials (Get-Credential).

        Windows Authentication, SQL Server Authentication, Active Directory - Password, and Active Directory - Integrated are all supported.

        For MFA support, please use Connect-DbaInstance.

    .PARAMETER Database
        The database or databases to add.

    .PARAMETER Schema
        Filter the objects based on schema

    .PARAMETER Object
        The object(s) to create the tests for

    .PARAMETER OutputPath
        Path to output the test to

    .PARAMETER Creator
        The person that created the tests. By default the command will get the environment username

    .PARAMETER TemplateFolder
        Path to template folder. By default the internal templates folder will be used

    .PARAMETER TestClass
        Test class name to use for the test

    .PARAMETER InputObject
        Takes the parameters required from a Login object that has been piped into the command

    .PARAMETER WhatIf
        Shows what would happen if the command were to run. No actions are actually performed.

    .PARAMETER Confirm
        Prompts you for confirmation before executing any changing operations within the command.

    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

function New-PSTGTableColumnTest {
    <#
    .SYNOPSIS
        Function to test thee columns for a table

    .DESCRIPTION
        The function will retrieve the current columns for a table and create a test for it

    .PARAMETER SqlInstance
        The target SQL Server instance or instances. Server version must be SQL Server version 2012 or higher.

    .PARAMETER SqlCredential
        Login to the target instance using alternative credentials. Accepts PowerShell credentials (Get-Credential).

        Windows Authentication, SQL Server Authentication, Active Directory - Password, and Active Directory - Integrated are all supported.

        For MFA support, please use Connect-DbaInstance.

    .PARAMETER Database
        The database or databases to add.

    .PARAMETER Schema
        Filter the tables based on schema

    .PARAMETER Table
        Table(s) to create tests for

    .PARAMETER OutputPath
        Path to output the test to

    .PARAMETER Creator
        The person that created the tests. By default the command will get the environment username

    .PARAMETER TemplateFolder
        Path to template folder. By default the internal templates folder will be used

    .PARAMETER TestClass
        Test class name to use for the test

    .PARAMETER InputObject
        Takes the parameters required from a Table object that has been piped into the command

    .PARAMETER WhatIf
        Shows what would happen if the command were to run. No actions are actually performed.

    .PARAMETER Confirm
        Prompts you for confirmation before executing any changing operations within the command.

    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

    .EXAMPLE
        New-PSTGTableColumnTest -Table $table -OutputPath $OutputPath

        Create a new table column test

    .EXAMPLE
        $tables | New-PSTGTableColumnTest -OutputPath $OutputPath

function New-PSTGTableIndexTest {
    <#
    .SYNOPSIS
        Function to test the indexes for a table

    .DESCRIPTION
        The function will retrieve the current indexes for a table and create a test for it

    .PARAMETER SqlInstance
        The target SQL Server instance or instances. Server version must be SQL Server version 2012 or higher.

    .PARAMETER SqlCredential
        Login to the target instance using alternative credentials. Accepts PowerShell credentials (Get-Credential).

        Windows Authentication, SQL Server Authentication, Active Directory - Password, and Active Directory - Integrated are all supported.

        For MFA support, please use Connect-DbaInstance.

    .PARAMETER Database
        The database or databases to add.

    .PARAMETER Schema
        Filter the tables based on schema

    .PARAMETER Table
        Table(s) to create tests for

    .PARAMETER OutputPath
        Path to output the test to

    .PARAMETER Creator
        The person that created the tests. By default the command will get the environment username

    .PARAMETER TemplateFolder
        Path to template folder. By default the internal templates folder will be used

    .PARAMETER TestClass
        Test class name to use for the test

    .PARAMETER InputObject
        Takes the parameters required from a Table object that has been piped into the command

    .PARAMETER WhatIf
        Shows what would happen if the command were to run. No actions are actually performed.

    .PARAMETER Confirm
        Prompts you for confirmation before executing any changing operations within the command.

    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

    .EXAMPLE
        New-PSTGTableIndexTest -Table $table -OutputPath $OutputPath

        Create a new table column test

    .EXAMPLE
        $tables | New-PSTGTableIndexTest -OutputPath $OutputPath

        Create the tests using pipelines

This is an example configuration file

By default, it is enough to have a single one of them,
however if you have enough configuration settings to justify having multiple copies of it,
feel totally free to split them into multiple files.

<#
# Example Configuration
Set-PSFConfig -Module 'PStSQLtTestGenerator' -Name 'Example.Setting' -Value 10 -Initialize -Validation 'integer' -Handler { } -Description "Example configuration setting. Your module can then use the setting using 'Get-PSFConfigValue'"
#>

By default, the files of this module are read as string value and invoked, which is faster but worse on debugging."
Set-PSFConfig -Module 'PStSQLtTestGenerator' -Name 'Import.IndividualFiles' -Value $false -Initialize -Validation 'bool' -Description "Whether the module files should be imported individually. During the module build, all module code is compiled into few files, which are imported instead by default.
