Quality Assurance: key factors affecting software testing strategies

Software testing has become a dynamic context-dependent field. Exposit QA Engineers are continuously learning new testing techniques, approaches and tools.

What are considerable factors affecting software testing?

  • Planning
    Planning in software testing is essential. Quality Assurance process relies on many aspects including test estimation and planning. Main things that should be estimated are human resources, time, cost and risks. Clear understanding of risks and amount of work may improve further productivity. Some software tests can be applied even on the requirements’ analysis stage. It may reduce possible bugs before production.
  • Time
    As there are some projects where time pressure takes place, it is important to be careful with test estimation. Time required for quality testing depends on skills, testing approaches and techniques, development team and environmental issues. If software testing on multiple devices is estimated at several hours, don’t expect good results. Usually quality software testing takes 15% of the total estimation, but it always depends on the number of devices.
  • Size & Complexity
    Complex and large scale projects have a number of features that require more skills and time for testing. New functionality needs to be covered by tests. Scope of work and technologies affect testing techniques and may change them within the project. That is why continuous software integration needs continuous testing and time. Testing techniques also vary by project type: Web, Mobile or Desktop. Every type has its own specifications and pitfalls. Users interact with mobile and web apps in different ways. For example, mobile products are faced with the problem of significant differences in screen size.
  • Documentation
    Detailed testing documentation may improve QA services as it helps to understand better how the product should work and make acceptance simpler. The time spent by developers to clarify possible inaccuracies is often less than the time testers spent to describe bugs in details in testing documentation. Carefully collected requirements make QA process simpler and faster.
  • Skills
    QA team is closely connected with production, that is why skills of all the team are important. Experienced developers deliver less bugs while skilled QA engineers process them faster. QA Engineer should be not only skilled, but also collaborative, diplomatic and creative to deal with unexpected issues quickly. In case of automation testing QA Engineer should have basic knowledge of programming languages to write autotests. Non-properly prepared design also can lead to the number of bugs.
  • Team interaction
    Testing depends on development team firstly. Productive communication between Engineering and QA department helps testers use actual information and solve issues quickly. Communication with development team allows testers to learn and improve their skills. Test-oriented team produces quality results and delivers projects in time. However, team should make quality a priority, not software testing itself.
  • Methodology
    Methodology used in project determines how testing process will go further. Testing approaches and techniques may vary in Agile, Scrum, Waterfall and other methodologies. For example, automation testing throughout the project will perfectly suit Agile with often changing requirements. In Waterfall methodology software testing is usually a single stage.
  • Trends
    Trendy technologies like Artificial Intelligence and IoT may change testing techniques. Artificial Intelligence can bring a number of benefits to software testing. There can be found tests’ reusability, easy CI/CD integration and lower price for QA services. Distribution of IoT devices may lead to the emergence of new testing approaches.
