Future Plans

Writing a PowerShell module was a goal that I’ve had for myself since I learned of PowerShell Gallery and helper modules such as Plaster, PSDeploy, BuildHelpers, InvokeBuild, and Pester. I have never worked with CI/CD build pipelines prior to this and a tool like AppVeyor was extremely foreign. I’m really happy with the progress that I’ve made, and while it isn’t perfect by any means, it works!

Background

When I decided that I wanted to write a module, I had the same thought that I’ve had plenty of times in the past when I set out to make a video game: I have no idea what I actually want to make. However, I did know that I wanted to try my best to check a few boxes with my first module:

The module needed to be as user-friendly and small in scale as possible, while still maintaining a realistic use

The module should be useful in an enterprise environment as well as general public use

A build pipeline should automate all building, testing, and deployment

I’ve recently done some work with iPerf to test some internal network connections in the office, and I realized that network bandwidth testing was a simple concept (user-friendly), small in scale, useful in an enterprise environment, and useful to the general public. I found that common public network bandwidth testing tools such as Speedtest by Ookla don’t have a public API, but iPerf does have a Chocolatey package available. Thus, PSSpeedTest was born.

Features

Set-SpeedTestConfig sets the JSON configuration file that stores default speed test servers/ports for public internet and local network speed tests.

sets the JSON configuration file that stores default speed test servers/ports for public internet and local network speed tests. Get-SpeedTestConfig prints the current default configuration to the screen.

prints the current default configuration to the screen. Invoke-SpeedTest runs a speed test against 1) the stored public internet server (and optional port) using the -Internet switch, 2) the stored local network server (and optional port) using the -Local switch, or 3) a specified server (and optional port) using the -Server and -Port switches.

runs a speed test against 1) the stored public internet server (and optional port) using the switch, 2) the stored local network server (and optional port) using the switch, or 3) a specified server (and optional port) using the and switches. Install-SpeedTestServer sets up an iPerf speed test server on 1) the local computer if -ComputerName is not specified (or a domain-joined network computer if it is), 2) on a port besides the default of 5201 if -Port is specified, 3) using credentials other than those of the current user if -Credential is specified.

I’m still trying to determine what the best means of documenting each function is; currently each function has detailed comment-based help available with Get-Help FunctionName -Full , but platyPS might be a better and more readily-available option that doesn’t require installing the module prior to reading the help. I’d rather not have the full usage of each function detailed in the primary module readme.

A means of decommissioning a speed test server deployed via Install-SpeedTestServer

If you’re so inclined, give the module a try and submit some pull requests if you see anything that you want to improve! My next post will detail my process of creating the pipeline that I use for working with this module.
