Skip or Only Run a Test with JavaScript Mocha / / No Comments Whenever I start to feel anxiety about a big change I’m making, I start writing more unit tests. I’ll write down my fear and then write a test that attacks, and eventually relaxes, that fear. There are two actions that I’ve been frequently using with test writing: skipping all but one test or single tests. Skip a Test Oftentimes I will create tests with empty bodies so that I don’t forget to write them.

Using the Adobe PDF EMbed API with Vue 3 / / No Comments A long time ago, ok, February of last year, I posted about using the Adobe PDF Embed library with Vue.js: Using the PDF Embed API with Vue.js. The main issue with our Embed library and libraries like Vue is a "chicken and egg" issue.

Set Brave as Default Browser from Command Line / / No Comments I’ve been a huge fan of the Brave web browser for years. They’re crypto-friendly, provide native ad-blocking features, and even provide Tor integration. Whenever I set up new systems, I automate Brave as the default browser. You can use the following shell command to set Brave as the default browser: open -a "Brave Browser" --args --make-default-browser Brave has been an excellent browser with a progressive outlook web browsing. I recommend everyone use Brave! The post Set Brave as Default Browser from Command Line appeared first on David Walsh Blog.
