Enhancing the quality of software products while bringing them to market quicker is a key aim of business leaders. By using Testhouse’s experience and expertise in DevOps principles and processes, businesses can achieve these goals and gain a vital competitive advantage.
DevOps — Continuous Delivery, breaks down the distinction between the development of a software
product and its operational implementation. The process is done by seeing all stages as interdependent and integrating quality assurance through continuous testing and feedback as early as possible in the development process.
By implementing Continuous Delivery, a development team can:
DevOps uses both lean principles – starting small and making continuous adjustments based on customer feedback – and agile principles – in which project plans and priorities are adjusted in the light of development and customer feedback.
A discovery workshop that will help your organisation to understand your business and IT goals for DevOps and help identify gaps in your DevOps capabilities that IBM and Testhouse can help address. The result of the workshop is a prioritised list of DevOps practices and a roadmap for their adoption.
The workshop is facilitated by IBM and Testhouse DevOps Subject Matter Experts and run over a day with key organisation functions (e.g. product management, dev, testing, SEC, IT Operations and sometimes marketing) present at the workshop and the report by IBM/Testhouse is presented a few days later in about 2 hours.

To enable continuous delivery, you need a mechanism to assess the quality of your software every time a change is made. To accomplish this, different types of automated tests need to be in place:
Unit Tests/BVT are run during the build to ensure no regression defects have been introduced
Integration Tests ensure that the modules or components can interoperate
Automated Acceptance Tests validate that the software is meeting certain requirements (mini regression suite)
To ensure a reliable and repeatable process, we need to confirm that software can be recreated at will. Moreover, if Continuous Integration is in place, a build is triggered every time a developer commits a change to version control.
The build process is the first quality gate as build verification tests, i.e. Unit Tests, are executed to verify that low level methods are still meeting their requirements. This is part of regression testing at a low level.
Build provides a fast feedback loop to developers informing them as soon as possible if any unit testable defect has been introduced.
Modern applications are complex and may involve hundreds of services. If a service is not developed yet, it may prevent integration testing. Also third party services may not be available for testing or may be very
expensive to use.
To solve such issues, Service Virtualisation creates virtual components that simulates those services. Service Virtualisation can be integrated to your automated deployment script and consequently allows testing to occur earlier, being automated or manual.

With Continuous Delivery, we need to test the application as often as possible. This is even more true with Agile teams where development iterations are short.
To meet the quality goals, the software goes through various test cycles, and several test environments need to be in place to achieve that.
With automated deployment, each new valid build can be deployed and tested automatically or at the push of a button through an approval step. This creates a reliable process that minimizes delays and resource dependencies.
This capability can be stretched even further with the ability to:
