There’s some preamble here. Jump to solution Recently, I’ve been working on a client project that needs to function offline. This means that I have a subset of tests where I need to change the connectivity status of the browser driving the tests to simulate being offline to make assertions that the application is behaving correctly. I already knew that...
A very handy API I’ve stumbled across today: page.driver.browser.manage.logs.get(:browser) This returns an array of Selenium::LogEntry instances which have the expected properties - level, timestamp, and message. You can use standard Enumerable methods to filter the log entries down to the information relevant to you. For example, all error messages: page.driver.browser.manage.logs.get(:browser).select { |le| le.level == "SEVERE" }.map(&:message) => ["http://127.0.0.1:40539/madeup - Failed...
I’ve been porting some previously server-rendered Rails templates to instead sit within a React application. This particular application uses Foundation Sites for base styles, and uses some of Foundation’s components which use Javascript to function - mostly basic stuff like data-dropdown, data-accordion, data-tabs. Foundation (still) uses jQuery for setting up these elements, and by default, initializes based on the ready...

I use ActionMailer::Previews whenever I am implementing a transactional email. They’re a super handy way of working with email development, and I’ve even enabled them in UAT environments before so clients and designers can check the email easily. In many apps, nearly all the transactional email is actually sent by Devise, so I wanted to set up a ActionMailer preview...
Ever seen the error “You must use Bundler 2 or greater with this lockfile.” trying to build a Docker image from a Dockerfile that uses an older Ruby version? Even though you are gem installing the correct version of Bundler? It turns out that the Ruby Docker images set an environment variable called BUNDLER_VERSION, which Bundler will always try to...
Every so often I will need to take some kind of key file - like a PGP key, SSH, OpenSSL, that kind of thing, and be able to paste it into a one-line text entry somewhere. Maybe a .env file, or shell script, or some piece of infrastructure that just accepts a text field as the input (like CI configuration)....
If you’ve got a large zipfile, or just a badly named one and you’d like to quickly take a peek at what’s inside it, there’s a handy flag that can be passed to the unzip utility (apt install unzip): unzip -vl path_to_zip.zip This yields an output like: root@224cb547fae0:/usr/src/app# unzip -vl spec/fixtures/example.zip Archive: spec/fixtures/example.zip Length Method Size Cmpr Date Time CRC-32...

bat bat is cat with syntax highlighting, but is still compatible with pipes, etc. Really neat. I like the filename header. Github: https://github.com/sharkdp/bat jira A CLI for Jira. Maybe it’ll be faster than using the web interace??? Regardless, it supports a fancy config loading system that looks like I can configure it as part of my tmux setup to pop...
