Kontinuierliches Software Testing sorgt dafür, dass die Qualität Ihrer Softwarelösungen stimmt und die Kosten niedrig gehalten werden.

Why companies benefit from automated software testing

David Flury, Software Engineer, Sevitec

Automated software testing as a success factor. Terms such as „continuous deployment“ and „continuous delivery“ play a major role in modern software development within the DevOps principles. However, one important need which is often ignored is continuous software testing. With proper testing environments, a high level of software product quality can be achieved and delivered within the planned budget.

Continuous software testing saves costs and reduces mental stress

When testing is carried out only at the end of a development stage – and in a worst case only by the client – significant quality issues tend to emerge which must to be fixed at a late stage. As a result, often unplanned re-development loops become necessary, causing increased financial expenditure.

Continuous and automated software testing throughout the whole development process tracks the quality level and allows software developers to be held accountable for the future software operation. In this way, quality management becomes a core theme instead of a largely neglected task at the end of a software project.

Software testing at the highest level

In a „test driven development“ (TDD), the process of testing is taken a step further. Tests are written right at the beginning of the development process before the actual logic is implemented. Additional principles such as „pair programming“ provide development teams with fresh input and foster cooperation.

Thanks to continuous software testing, efforts related to quality assurance are spread throughout the entire project. Furthermore, automated tests prevent future – and mostly unnecessary and unplanned – subsequent costs. Therefore, it makes sense for corporate management to support measures of continuous software testing.

Testing allows for timely optimization of future software solutions

In today’s IT world, the term „electronic data processing“ (EDP) is no longer commonly used. Nonetheless, it perfectly describes the requirements of most software projects. Input is manipulated by a „magical code“ which results in the desired output. Clients, however, are often uncertain what the input should be and which ideal output they want to achieve.

The concept of testing helps in this respect, as it provides continuous input when working out optimal software specifications. Ideally, clients consider themselves as part of the quality management team right from the beginning of a software development project. As such, single requirements are identified in a test-driven environment and clients are constantly reassured that the delivered result corresponds to their original needs. Any discrepancies and failures are immediately visible at the beginning of a development phase and can be promptly fixed in a specific testing environment.

Automated testing leads to better software architecture

Software developers are both engineers and artists. Even though the main source code of a software usually remains hidden, it should nevertheless be well-structured and free of redundancies. Proper testing is only possible when single components are isolated and when there are no unnecessary dependencies.

In cases where a developer keeps testing processes in mind when developing a new software, a better software architecture is automatically achieved. Thanks to such an approach, developers remain motivated to review concepts and achieve optimal software structures. This way, e.g. implementing business logics of UI is prevented. Even though such an architecture may function well at the beginning, it would not be testable and might cause unexpected difficulties when expanding the software solution in the future.

An optimized architecture is not only is beneficial to quality management. It also provides an ideal basis for the future development of additional functionalities.

Peace of mind thanks to testing

Each code change is a potential source of errors (regressions). If a changed component is monitored by several tests and keeps fully functioning once the adjustment has been executed, the environment and attitude before a major release can remain relaxed and free from worry.

Regular and meaningful software testing encourages developers to critically monitor past developments and continuously replace them with improved solutions. However, such an approach is only possible if damage of existing functionalities can be reliably avoided.

Sevitec provides optimal software solutions thanks to testing

Regular testing is key for continuously achieving better software solutions. Among development teams, both a rethinking process and ideally a change of perspective are often needed to focus on defined test cases.

At Sevitec we bring the required attitude to your projects and provide you with high-quality solutions at a fair price level fulfilling today’s and tomorrow’s needs.
