  • Effective Test Strategies for Testing Front-end Applications using LaunchDarkly Feature Flags and Cypress. Part2: testing
    The proper solution to tests sharing state would be randomization. Unless we are locked to real hardware - even then there is virtualization - we can randomize anything. We saw an example of this in the blog post about email testing , under the section Achieving Stateless tests with unique emails. With mailosaur any-name@unique-serverId.mailosaur.io went to that unique email server inbox, and we differentiated... - Source: dev.to / about 2 years ago
  • Test emails effortlessly with Cypress, Mailosaur and cy-spok
    There are plenty of email testing solutions available, and combinations of test frameworks that integrate with them. For the code snippets and working examples, we will be using Cypress and Mailosaur, but the ideas should generally apply to any tuple of email services and test automation frameworks. - Source: dev.to / about 2 years ago
  • Ask HN: Twilio blocked our account and with it hundreds of our customers

Having been a customer since our launch [1], and very early after theirs, it has been really sad and frustrating to see that friendly distrupter energy zap out of the service. I get why businesses go through that changes like this during... - Source: Hacker News / about 3 years ago

  • Has anyone setup a Linux based internal only smtp relay?
    I've had something of the same experience with Postfix, u/0x29aNull. Check out OpenSMTPD. It is lightweight and standards compliant. I know that there are packages for Debian and Alpine Linux. There may also be ones for Fedora/RHEL derivatives. I use it in my environment on OpenBSD. Source: about 1 year ago
  • DKIM Migration: Rpamd instead of DKIMproxy out on OpenBSD / OpenSMTPD
    When I installed Rspamd with on OpenBSD / OpenSMTPD the other day, DKIMProxy out (dkimproxy_out daemon), which had been got via OpenBSD Ports package system, was used to add DKIM signatures to mails in order to improve security on emails. - Source: dev.to / almost 3 years ago
