Radio Liferay Episode 59: Testing @ Liferay with Kristoffer Onias and Victor Ware

  Yay, another episode, and maybe in time to sweeten your trip to Devcon in Amsterdam. I spoke to Kristoffer Onias and Victor Ware. Both work on testing Liferay with different areas of interest. You'll hear quite a bit about what Liferay does internally on testing.

I actually talked to them quite a while ago, and the episode has been sitting on my disk since then.The numbers that you hear may no longer be accurate, but the overall information definitely is. Sorry for keeping it a secret for so long (there's an even longer kept secret... up next...)

We're talking about these (and more) topics

  • Different levels of Tests:
    • Unittests
    • Integration Tests
    • Functional Tests
  • How SPA influenced frontend testing
  • Selenium, Selenium IDE, Web Driver, Capybara, Docker, and Jenkins
  • How pull requests are tested before they reach their addressee
  • The scale of Liferay's testing infrastructure
  • KC's (at the time) still unnamed project. Watch out for him at the North American Symposium for updates to this. Oh, and: By now his project actually has a name: Testray
  • Maintenance of large test sets - UI locators etc.
  • SevenCogs and its resurrection
  • How to scale testing infrastructure for potentially a lot more servers and environments
  • The Test Pyramid
  • A wild idea: Livestream of test runs
  • Liferay's Testing Whitepaper and a Testing Webinar
  • 50 shades of red and its part 2

Radio Liferay Episode 43: Brett Swaim on Application Performance Monitoring

  I'm talking with Brett Swaim, Principal Consultant at Liferay US, on application performance monitoring, horror stories and things to avoid. Brett is dealing with a lot of customers. He's one of Liferay's go-to resources for performance tuning and monitoring. Brett had a presentation on DevOps Best Practices with Liferay, Logstash, Kibana, Elasticsearch, and New Relic  at Devcon (among other symposiums and events). If you missed it or just want the audio summary (both were my motivations to talk to him), we're talking about his experience, using one of the projects (an unnamed one) as an example.

This is a short conversation as we didn't have a lot of time in between different appointments, but we've committed to making this a series of episodes on similar topics - and more in depth.

We talked about

  • Application Lifecycle and Performance monitoring, New Relic  (used as a sample here), Compuware , AppDynamics. Or check the Gartner Quadrant
  • If you can't host in the cloud, you can use the same strategies that Brett is talking about with on-premise solutions
  • How do you know your application is slow?
  • ELK-Stack (Elasticsearch, Logstash and Kibana)
  • adding page load times to Apache Logs
  • It matters where you measure from: Internal network, external network.
  • Default configuration of Liferay - memory, garbage collection and other JVM settings
  • You can have too much memory in your JVM
  • Liferay's Whitepapers have starting points, you shouldn't use them as your final settings.
  • ...and you'll actually need to measure for yourself in order to find your number...
  • CDN setup and its results on high volume site
  • Be proactive. You'll find bottlenecks before your users do.
