Test a Local Jenkins Instance on MacOS: Download, Setup, and Run Groovy Scripts Locally

About

There are many ways to test Jenkins...

Jenkins Pipeline Unit is great but it's generally recommended to keep all of your logic with stages and not get too crazy with custom Groovy in your pipeline. Though, it's a great option if you have a very advanced use-case and want to make sure your code is reliable.

The Replay Pipeline Run Option is awesome if you want to verify a quick change or iterate quickly on a previously setup pipeline. But it only allows for altering Jenkinsfile Code and runs against the production Jenkins Instance.

Convert (Screen Capture) .mov files to GIF format using Ffmpeg and Gifsicle (MacOS)

Prompts for path to .mov and allows user to enter a .gif name. Then converts that .mov file to a .gif and saves to ~/Downloads/.

Inspired by: https://gist.github.com/dergachev/4627207

To use:

• Save the code from this gist into a file and name it something like convert_movie_to_gif.sh, and then run chmod +x ./convert_movie_to_gif.sh to make it executable.
  • If gifsicle isn't installed, the script will tell you.

Emulator over gRPC Examples

Thanks to Erwin Jansen for these samples and this readme. (I just formatted this and threw it in a gist to make it more shareable and readable)

Samples can be downloaded here: https://android.googlesource.com/platform/external/qemu/+/refs/heads/emu-master-dev/android/android-grpc/docs/grpc-samples

Caveats: Experimental feature!!

This is currently an experimental feature, and as such there are some things lacking that might be important if you want to use this in production:

Using ADB to control Accessbility settings for easier testing with Android Emulators + Real Devices

It's a lot easier to test accessibility on the fly using ADB. This gist attempts to make the days of navigating through the Android device settings UI to change Accessibility settings obsolete.

These ADB commands will hopefully encourage Android developers to test and use their apps with common Accessiblility settings enabled.

Credit to James Nitsch for inspiring this, and for figuring out the put commands to enable these settings.

Install and Create Emulators using AVDMANAGER and SDKMANAGER

TL;DR

For an emulator that mimics a Pixel 5 Device with Google APIs and ARM architecture (for an M1/M2 Macbook):

1. List All System Images Available for Download: sdkmanager --list | grep system-images

2. Download Image: sdkmanager --install "system-images;android-30;google_atd;arm64-v8a"
