Quality Engineering Intern/CoOp Position

As a Computer Science major (undergraduate or graduate degree programs), why should I choose Quality Engineering as part of my internship or co-operative work experience? I am studying in a computer science degree program to be a software developer and expect to have a developer position upon graduation from college. This post is a pitch to College Students to consider at least one Quality Engineer internship/CoOp job so that you become a more well rounded developer. You should find the job to be career enriching and offers you another career choice.

Zero BugsQuality Engineering (QE) is the practice of defect prevention (finding defects as the code is developed) as opposed to quality assurance (verification and validation after the code is developed), striving towards zero defects in the field. Quality Engineering is early acceptance test planning in agile product delivery teams, collaborative with developers for both exploratory and automated testing, and centers around continuous integration. Quality Engineering embraces traditional testing techniques of defect discovery and test coverage in parallel with developing features.

Quality Engineering as has come a long way over the years. Testing was once considered a downstream activity in a separate test group that pushed defects into a large backlog for developers to fix in subsequent phases. This was usually made up of minimally technical testers with experience and domain knowledge of the customer’s needs. Test automation in the past was a small group of highly skilled test developers who automated tests written by others, requiring stable code to be worthwhile automating. In contrast, the modern software tester has a technical degree (usually computer science), is embedded in a software development project team, is highly collaborative with the developer counterparts in the team, is skilled in traditional test approaches, is skilled in exploratory and automated tests (creating regression tests along the way), and is the voice of the customer throughout the feature development life cycle. Today both the developer and the tester are engineers working together to deliver working software in small iterations, where software is delivered in small testable chunks.

Quality Engineering is a role in Agile product delivery organizations that:

  • develop and maintain test automation infrastructure and processes
  • develop automated tests (functional, integration, and load/performance) for GUI (graphical user interface) and API (application programming interface) automated tests
  • contribute to continuous integration practices
  • exercise continuous deployment and both regression and exhaustive testing
  • apply customer domain expertise for comprehensive test coverage, and exploratory and fuzz testing
  • validate acceptance criteria that developed and re-factored code meets customer and stakeholder expectations
  • develop and work with test fixtures (software containers to test components in isolation) and mocking (simulated responses from third party and internal integration interfaces)

Quality Engineering role has become increasingly more developer oriented, by participating in:

  • code design and test planning reviews
  • early tests of newly developed code in developer sandboxes
  • develop, review, and use deployment automation scripting (including up-time deployment)
  • develop, review, and use monitoring and up-time reporting tools
  • assess load distribution for high availability, redundancy, and fault tolerance,  in hosted systems
  • test integration with third party services, and their mocks

Quality Engineering is a an integral part of scaling development. Agile development includes designing for re-use, routine re-factoring, unit tests (including mocking and stubbing for negative tests), and building integrated code frequently. Work is broken down into the smallest testable work items, such that development and test is a continuous practice. A combination of unit tests (authored by the Developer) and regression tests (authored by the Quality Engineer) provide a library of automated tests that run often and identify problems that break running software. This library of automated regression tests allows the planned iteration time (to visually test and develop additional automated tests) to remain constant and predictable.

Test Accumulation Graph

Regression Time in this graph is the time it would take to manually exercise regression tests as the code base increases over time.

Without well written regression tests, the amount of time it takes to test increases exponentially with the addition of new working code (Test Accumulation graph). While adding features to a product with each development cycle iteration, the time to test manually increases (usually linearly). Automated regression tests absorb the time to test, enabling the available test time to be focused on testing changes and writing new automated regression tests. The library of automated can be run over and over again frequently to promptly catch problem regressions (code or configuration changes that result in breaking another part of the system). Therefore, agile product delivery teams rely on the accumulation of tests as part of delivering working software to the customer.

Having experience working as a Quality Engineer will provide you with a deep understanding of core test techniques, a test perspective on continuous integration and continuous delivery approaches, a sense of what acceptance criteria means to consider development tasks done, and designing software applications for test-ability. CI and CD drive defect prevention, assuring that working software remains working. Quality Engineering is a different kind of developer and knowing this role well will help you work collaboratively with quality engineers while working as a development engineer in the future. You may also find that Quality Engineering is a career path that interests you more than Developer Engineering.

Constant Contact Quality Engineering is organized into roles of QE Architecture, a specialized test team as a center of excellence in test automation, and embedded quality engineers on each agile product delivery team. There is typically a 3:1 ration of developers to quality engineers whom operate collaboratively with developers to deliver new and re-factored infrastructure and customer facing features. Most of our Quality Engineers have a degree in computer science (or related major), many have an MSCS, and we even have a PhD in the team. Consider joining our Constant Contact QE organization for one or more of your internship or co-op work sessions. This experience will contribute to building a well-rounded developer education and a chance to learn the other side of delivery software.
