Integration and systems tests ensure that software products properly make their implemented features available to the user. A software product should be treated as a black box whose available functional and non-functional properties are to be verified. Acceptance tests similarly ensure that the right functionality has been implemented, and that running or using the software actually provides its users with added value.
Whether a test strategy or a test plan, whether test management or test execution management, or whether manual or automated testing is needed: we have the resources at our disposal. And we make specialists or complete project teams available to handle these tasks.
