1. Generate self-signed certificate

keytool -genkey -alias wiremock -keyalg RSA -keysize 1024 \
    -validity 365 -keypass password -keystore identity.jks -storepass password

Important: keypass must equal storepass, or else you'll receive java.io.IOException: !JsseListener: java.security.UnrecoverableKeyException: Cannot recover key

2. Start wiremock with the new keystore and HTTPS enabled

# What is this for?
# This script fixes an issue appeared for some Xcode users where it would show long identifiers
# in the list of simulators instead of usual short names. This is caused by duplicate simulators
# being sometimes created after switching between Xcode versions, with the same
# device type + runtime pair occurring more than once in your list of available simulators.
# Instead of showing the same simulator name twice, Xcode defaults to simulator identifiers.
#
# What it does?

Don't use VPN services.

No, seriously, don't. You're probably reading this because you've asked what VPN service to use, and this is the answer.

Note: The content in this post does not apply to using VPN for their intended purpose; that is, as a virtual private (internal) network. It only applies to using it as a glorified proxy, which is what every third-party "VPN provider" does.

• A Turkish translation can be found here, contributed by agyild.
• There's also this article about VPN services, which is honestly better written (and has more cat pictures!) than my article.

WDIO Mocha plugin is an useful adapter to use Mocha in WDIO. Mocha options can be provided through wdio config file or through command line argument. To invoke WDIO from npm scripts passing command line arguments is tricky. 

Mocha Tags are useful to run specific methods tagged by common name. Requirements like running smoke test, remote, local, headless, fast, slow tests can be done using tags. https://github.com/mochajs/mocha/wiki/Tagging

Let say i have a package.json scripts section like below

"scripts": {
    "smoke": "node node_modules/webdriverio/bin/wdio conf/wdio.conf.js --mochaOpts.grep=@Smoke",
    "slow": "node node_modules/webdriverio/bin/wdio conf/wdio.conf.js --mochaOpts.grep=@Slow",
    "fast": "node node_modules/webdriverio/bin/wdio conf/wdio.conf.js --mochaOpts.grep=@Fast"

Pimping Up Your PowerShell & Cmder with Posh-Git, Oh-My-Posh, & Powerline Fonts

Backstory (TLDR)

I work as a full-stack developer at work. We are a Windows & Azure shop, so we are using Windows as our development platform, hence this customization.

For my console needs, I am using Cmder which is based on ConEmu with PowerShell as my shell of choice.

Yes, yes, I know nowadays you can use the Linux subsystem on Windows 10 which allow you to run Ubuntu on Windows. If you are looking for customization of the Ubuntu bash shell, check out this article by Scott Hanselman.
