CHALLENGE OF CONTINUOUS DELIVERY

Posted on 24 April 2015
CHALLENGE OF CONTINUOUS DELIVERY

Companies today are compelled to develop and test products in a much shorter release cycle to stay competitive in the market place. Add to that, market expectations that these products need to be released on multiple platforms and devices. The old linear fashion of developing software is therefore undergoing a change.

The Lean Startup Concept of releasing "minimum value product" to the market and then using customer feedback to build iteratively on the product is becoming universal. Organizations tend to break up the product requirements into batches, which helps them to reduce "work in progress" and increase output. These batched requirements are then lined up for the continuous delivery process.  Hence, in a way, DevOps and Agile are acting as major drivers for continuous integration and rapid delivery of minimum value product to the marketplace.

To become effective in this continuous delivery environment, collaboration across roles is becoming more important than ever before. Success in this continuous delivery process depends on different software development roles, such as developer, tester, and operations, coming closer and working together. Additionally, a highly automated process that supports fast feedback loops and accelerated delivery schedules by reducing the handoffs and manual work across cross-functional teams is important.

A successful shift to continuous delivery also depends on having the right people, process, and tools in place. From a people perspective, implementing change could be risky and requires commitment from top management and bottom up action from testers and developers. From a tool perspective, testing often acts as a bottle neck to achieving a speedy process. Automating development, test, and deployment processes for these different varieties of tests (acceptance, smoke, and regression, API, security, load, etc.) can become really challenging to achieve as well as maintain over time. If these tests are not managed properly, a continuous delivery process can go haywire quickly. Additionally, building a steady and predicable process that can respond to rapid changes in the code base quickly further complicates the process.

Most importantly, the more mature the continuous delivery process becomes, the more tests organizations have over time, and as a result the longer it takes the build system takes to run these tests.  Maintaining a balance between speed and reasonable test coverage can soon become challenging. As a result, in order to release on time in these reduced testing cycles, organizations many times tend to sacrifice test coverage to achieve speed. This often results in expensive defects to be introduced in the product.

EXPERIOR PROVIDES A SOLUTION

Using tools avalable from Experior we can solve these challenges by providing tools that help organizations automate the development-test process end-to-end. These tools allow organizations shift QA to the left with development, ensuring quality can be introduced in the process even before coding has begun. Additionally, any ambiguous requirements can be identified, which in turn avoids costly redevelopment costs in the future. Tests scripts can be reused across these different tools to reduce redundant efforts and save time. Additionally, with these tools you can:

  • Perform priority based testing QAComplete allows testers to prioritize test cases that have the greatest chance of failure.
  • Reduce redundant test cases, without impacting coverage: Using QAComplete, you can get combined insights into manual as well as automated test cases. Managers can also use reports to ensure proper test coverage exists.
  • Perform reusability across software development lifecycle: AlertSite UXM allows usage of SoapUI and Ready! API test scripts for SOAP and REST API Monitoring. Testers thereby don't have to write tests from scratch when testing functionality with the same logic. You can even combine Selenium WebDriver tests with other tests using TestComplete Web.
  • Ensure code quality: Collaborator helps developers to review each other's code and track review requests, thereby ensuring buggy code doesn't make its way to the SCM.
  • Reduce testing time by shifting testing to the left: With Service V, you can create virtual APIs. This saves test case creation and development time as testers can start creating test cases while the API is still being developed.
  • Automate Functional and API Testing: TestComplete and Ready! API solutions integrate with build systems such as Jenkins. This not only allows for automatic execution of front end GUI testing, but also ensures API tests can be executed when any build is triggered.
  • Reduce debugging time post deployment: AlertSite UXM allows operations team to perform root cause identification of performance issues all the way down to the code level, reducing post deployment resolution cost and time.
