It’s only rational to act preventively. The price of a software defect is significantly lower on the requirements stage of the development and grows up to 200 times in the release phase.
That noted, businesses pay up as much as $3 per every single line of code in order for it to be fixed and free of harmful defects. Do you know how many lines of code an app has? Just for safe measure, the simplest of calculators designed in C++ usually include 40 to 50 lines if the developer is any good.
Luckily tech businesses have the chance for outsourcing quality assurance to a www.deviqa.com, a professional QA company. Additionally they can embrace Continuous Integration.
CI or Continuous Integration is a practice that basically merges series of working copies into a single branch several times a day, while all code is covered with automated tests. This transition allows to improve development costs, enhance the speed and predict possible outcomes before deployment.
Software defects of all shapes and sizes simply don’t have the chance to sneak into the main branch as they are illuminated in cluster-sized personal deploys of a developer thanks to automated testing and, in some cases, pair programming with a QA engineer near.
Top challenges of CI
Things sound perfect on paper, yet implementation is not that flawless in reality. Here are several challenges dev teams need to overcome:
- Ensuring all tests are run from relevant git clones is an actual pain in the neck. A server on which the development is done needs to be educated with scripts to ensure that every commit of a developer has to be as independent as the United States of America. If eagles tend to make nests in your server room – don’t worry, you are simply on the right track.
- The large the team – the harder things get. It’s always harder to manage a crowd, right? So, unless you make the strategic decision of breaking the team into clusters working on different functionality elements the deployment is in danger.
- Your System Architect has to be a pure genius because if a mistake crawls into the system on his stage the whole process will break apart like a house of cards on a windy afternoon in West Carolina.
- Tests that are both reliable and repeatable can be nominated for the work of art awards. Good enough won’t do the trick as you simply don’t have the luxury of time to write new scripts for test cases and use cases on the go.
Continuous integration is a rather beneficial methodology if and only if you have a team of hardcore professionals at your disposal. In other cases it’s cheaper and more efficient to simply outsource quality assurance and quality control to a third party vendor.
