Testing in DevOps

  • Fast automated tests that run within our build and test environments whenever a new change is introduced into version control. In this way we can find and fix any problems immediately, as the Google Web Server example demonstrated.
  • By doing this, we ensure our batches remains small, and, at any given point in time, we remain in a deployable state.

Build the code & deployment

  • Automation utilities very much needed to build code quickly.
  • IBM Rational Team Concert, various CICS Tools and toolkits, and IBM UrbanCode Deploy provide the capabilities to support continuous delivery of enterprise applications for Mainframe projects.
  • Automatic releasing is the main task in DevOps.
