Get to know me easilyA software test is a systematic process for checking and validating software to ensure that it meets requirements and functions without errors. Software tests are an essential part of quality assurance and help to identify and rectify potential errors at an early stage. In the following, I will explain why software testing is important, how it works and which best practices can help make it a success.
A software test is the systematic examination of an application to find errors and ensure that it meets the functional and non-functional requirements. Various types of tests are used to check different aspects of the software.
The list presented here is not exhaustive and shows how the focus can be placed during a test session and which aspects can be paid particular attention to. I am happy to help with the selection of suitable methods and/or the implementation.
Structured tests enable errors to be detected and rectified at an early stage before they reach production.
Software errors can cause high costs and damage the company's image. Tests help to minimize these risks and ensure a seamless user experience for which the product is recommended.
Error-free and efficient software ensures a better user experience and increases customer satisfaction.
Regularly executed tests train the testers and thus save time and resources by optimizing repeatable processes. In addition, bugs are fixed at an earlier stage, which can reduce these costs by up to 80%.
A structured approach ensures that software tests are effective. The following steps are one way of doing this:
In addition to the approach, methods and tools to be used are defined. The time frame, resource requirements and test environment are also defined. The results are communicated so that specialist departments, for example, can adapt to them and make personnel available if necessary.
Based on the requirements (and experience), test cases are created that can be executed manually or automatically using the scripts derived from them.
Carrying out the tests (manual and/or automated) and documenting the results.
Any errors found are analyzed and documented. They are rectified in collaboration with the development team.
The regression test is used to ensure that the bug fixes themselves have not produced any new errors. Individual tests are repeated for this purpose.
The software quality is analyzed on the basis of the findings. Depending on the objective of the test, for example, a release recommendation is made - or not, if the quality does not meet the previously defined standards.
The earlier tests start in the development process, the lower the costs for bug fixes. This approach is also often called “shift left”.
Automated tests save time and improve test coverage, but should be used selectively as they are not a panacea and cannot replace thorough quality assurance.
Good test cases are traceable, reproducible and well documented. If no attention is paid to this, traceability suffers, which in turn can lead to time-consuming troubleshooting or coordination.
For an efficient use of resources, everything that can be covered by a unit test should also be done at this test level. End-to-end tests are many times more expensive to create, maintain and operate and should only be used for the use cases for which they are intended (preferably no limit value tests, but rather the interaction of the various system areas)
Test processes should be regularly reviewed and optimized in order to increase efficiency and effectiveness.
Problem: Unclear specifications lead to inaccurate tests.
Solution: Close collaboration with stakeholders to clarify requirements.
Problem: There is often not enough time or money available for comprehensive testing.
Solution: Prioritization of the most important test cases and automation of critical tests. Sensitization of management with regard to the scope that is really necessary.
Problem: Realistic test data is often difficult to obtain.
Solution: Use test data generation tools and anonymize real data. When anonymizing real data, it is IMPERATIVE to involve the person responsible for data protection in order to avoid legal problems.
Problem: Large and distributed systems make testing more difficult.
Solution: Modular testing and continuous integration with CI/CD pipelines while maintaining the correct test pyramid step.
Software tests are an indispensable part of software development to ensure quality, security and user-friendliness. A structured approach, the combination of manual and automated tests and the consideration of proven methods allow efficient and reliable tests to be carried out. Companies that invest in good test strategies benefit from stable and high-performance software products in the long term. I am always happy to support you in planning and carrying out a test run.
