How often should you test? Naturally, that depends on the risk profile and scope of the release, but the short answer is this... you should test as many times as it takes to give you confidence that your software is working as expected, every time, within your desired specifications. In practical terms, that equates to at least one test while the release is in pre-production, another in pre-production after the staging bugs have been remedied and one in production.
When done right, test automation can lead to significant efficiency and cost improvements. Unfortunately, many organisations fail to maximise the full potential of their automation program due to a number of common challenges. Here's how to overcome them...
The business environment is changing. Economies are no longer as stable as they once were and so there is far less tolerance of risk than there used to be. Quality assurance has become a focal point for business expansion as businesses try to attract and retain customers by improving service while cutting costs. Software applications in the financial sector in particular, and other areas as well, are now a vital part of customer interaction and retention. This means that companies are demanding faster development cycles while being less tolerant of failure, which is one of the main reasons why agile development is so popular.
Quality assurance is becoming ever more important as digital technology continues to expand its reach. The fact that the Internet continues to spread across the world while IT has become the goto technology for getting things done means that the need to develop and deploy dependable software is increasingly important.
Pleasing every stakeholder can be a problem in software development. Different people have different needs and desires. Some people may need certain functions while others want the application released as soon as possible. It’s important to realize that while it may not be possible to please everyone all the time, quality assurance is the best guarantee of happy stakeholders.
Software development has evolved to a point where the end user has become as important as the application itself. The days of people adapting themselves to software are gone and the need for software to adapt to people has made quality assurance testing a vital part of software development.
What is continuous delivery? It is a solution that is intended to eliminate the traditional slowdowns in software development. The basic idea is to develop a system that will gradiently improve software by the delivery of working software elements at each stage. These elements can be tested and assembled into a complete application while taking needed improvements and requirement changes into account. And so, continuous delivery is an approach to software development that allows users to receive new features as quickly as possible.
Ideally, UAT testing should provide the opportunity to uncover any remaining bugs, and to test usability directly in the operational environment. These tests should generate a confident certainty that the software will function as designed when it goes live. However, this isn't always the case.
These days it so easy for consumers to change technology products. Most technology is linked to a subscription based model which has no lock in dates and are typically month to month and based on consumption. Today, if a user is not happy with the experience and the quality of a product, they will pack up their bags and move to a competitor.
We all get too close to our own projects and it's totally human to do so. In fact, it’s called groupthink and it basically means that when you are too close to a team or a project, it can be difficult to see beyond you and your team’s view of the world.
