Learn Building Unconventional SQL Server Tools in PowerShell this weekend at SQL Saturday Chattanooga 2016

I’m presenting a session on Building Unconventional SQL Server Tools in PowerShell this weekend at SQL Saturday #498 in Chattanooga. Ever had records from a SQL Server database table come up missing? Maybe someone or some process deleted them, but who really knows what happened to them? Wouldn’t it be awesome to create a free tool with PowerShell that automates the task of sifting through the transaction log backups and even the active transaction log to determine when deletes occurred Read more [...]

PowerShell function to find information about module updates

I decided to update the one liner from my blog article last week and take it a step further by turning it into a reusable tool that displays information about module updates that are available regardless of where they were installed from. As shown in the previous results, the function lists modules that have updates available regardless of where they were originally installed from. It also lists the installed version and location Read more [...]

Update Manually Installed PowerShell Modules from the PowerShell Gallery

There are PowerShell modules that ship with Windows 10 that weren't installed from the PowerShell Gallery using PowerShellGet so they can't be updated using the Update-Module cmdlet. This also applies for any modules that you've installed manually yourself. The following PowerShell script retrieves a list of the most recent version of the modules in the all users path for PowerShell modules. It determines which ones weren't installed using PowerShellGet based on the hidden xml file that would Read more [...]

Learn PowerShell Desired State Configuration from the Trenches this weekend at SQL Saturday Pensacola 2016

I'm presenting a session on PowerShell Desired State Configuration from the Trenches this weekend at SQL Saturday #491 in Pensacola. There are lots of things to consider when configuring systems in your on-premises datacenters with Desired State Configuration depending on what the state of your current environment is, whether or not DSC will be configured to apply and monitor or apply and autocorrect configuration drift, and whether or not you’ll be using push or pull configuration mode. Read more [...]

Video: PowerShell Toolmaking with Advanced Functions and Script Modules

I presented a session on PowerShell Toolmaking with Advanced Functions and Script Modules this past weekend at SQL Saturday #521 in Atlanta. I decided to make an attempt to record my session which was presented live in front of a packed room full of attendees: The recording turned out very well considering I used the built-in laptop microphone and I moved around during my presentation. The audio levels have been tweaked because they were often too low depending on how far away I was from Read more [...]

Learn PowerShell Toolmaking with Advanced Functions and Script Modules this weekend at SQL Saturday Atlanta 2016

I'll be presenting a session on PowerShell Toolmaking with Advanced Functions and Script Modules this weekend at SQL Saturday #521 in Atlanta. Transitioning from writing PowerShell one-liners and basic scripts to creating reusable PowerShell tools with advanced functions and script modules can be a daunting task and with all the different ways that you’ll find on the Internet to accomplish the same task, it can definitely seem overwhelming. During this session, PowerShell MVP Mike F Robbins Read more [...]

Why isn’t Test Driven Development more widely adopted and accepted by the PowerShell community?

We've all heard that TDD (Test Driven Development) means that you write unit tests before writing any code. Most of us are probably writing functional or acceptance tests after the fact because the idea of Test Driven Development isn't clearly defined, at least not in my opinion. I originally thought it meant to write thorough unit tests to test all functionality for a specific piece of code such as a PowerShell function from start to finish before writing any of the production code for the function Read more [...]

Don’t use Default Manifest Settings when Dot-Sourcing Functions in PS1 Files from a PowerShell Script Module

I briefly mentioned and demonstrated something similar to this at the end of one of my sessions at the PowerShell and DevOps Global Summit 2016. Since then, I've tested more which has led to a better solution. We've all been taught that it's best practice to use a #Requires statement in our functions that specifies the required PowerShell version along with any module dependencies, but following this best practice has one unexpected side effect when dot-sourcing functions in PS1 files from a PSM1 Read more [...]

Be Mindful of Object Types when Writing Unit Tests and Performing Operational Validation in PowerShell with Pester

I recently wrote a Pester test that performs some basic operational validation (smoke tests) of SQL Servers. I've previously written similar tests as functions as shown in my "Write Dynamic Unit Tests for your PowerShell Code with Pester" blog article, but I decided to write this one as a script with the naming convention that seems to be recommended. The name of this particular test is "Validate-MrSQLServer.Tests.ps1". You're probably thinking "Validate" isn't an approved verb and you're right, Read more [...]

Keeping Track of PowerShell Functions in Script Modules when Dot-Sourcing PS1 Files

I'm picking up where I left off in a previous blog article "Write Dynamic Unit Tests for your PowerShell Code with Pester". I'm using the dynamic Test-MrFunctionsToExport Pester test that I wrote about in that previous blog article. Currently, the test is failing for my MrToolkit module that's part of my PowerShell repository on GitHub: Based on the previous results, I can easily determine that more functions exist in the module folder than are specified in Read more [...]

Video: Creating a Custom PowerShell Toolkit to Demystify DSC

Last week, on Monday (April 4th, 2016), I presented a session at the PowerShell and DevOps Global Summit 2016 on "Creating a Custom PowerShell Toolkit to Demystify the Intricacies of Desired State Configuration". The video from that presentation is now available: https://youtu.be/fOov9gkqFHs Here’s the abstract or synopsis for this presentation: "DSC (Desired State Configuration) can be very complicated when working in an environment where nodes are set to retrieve their configuration from Read more [...]

Write Dynamic Unit Tests for your PowerShell Code with Pester

I wrote a blog article on: "PowerShell Script Module Design: Placing functions directly in the PSM1 file versus dot-sourcing separate PS1 files" earlier this year and I've moved all of my PowerShell script modules to that design and while today's blog article isn't part of a series, that previous one is recommended reading so you're not lost when trying to understand what I'm attempting to accomplish. Most unit tests that I've seen created with Pester for testing PowerShell code are very specific, Read more [...]
