Testing is an important factor in any success story
In software projects, it is never too early to begin preparing your tests. The following examples illustrate the benefits of involving testers with appropriate test knowledge in individual activities within the software development life cycle:
Close cooperation between developers and testers throughout the development process
- If testers are involved in checking the requirement or refining user stories, they can use their specialist knowledge to find and remedy ambiguities and faults very early in the work product. The identification and correction of flawed requirements reduces the risk of producing inappropriate or non-testable functionality.
- Close cooperation between testers and systems designers at the design stage helps all those involved to better understand the system’s design and the corresponding tests. This increased awareness can reduce the risk of producing fundamental construction faults and makes it easier to design appropriate tests—for example, to test interfaces during integration testing.
- Developers and testers who work together at the coding stage have a better understanding of the code itself and the tests it requires. This reduces the risk of producing faulty code and of designing inappropriate tests.
- If testers verify and validate software before release, they are sure to identify and remedy additional faults that would otherwise remain undiscovered. This increases the probability that the product fulfills its requirements and satisfies all of its stakeholders.
In addition to these examples, achieving the previously defined test objectives will also aid successful software development and maintenance.
