He was responsible for several software development project in industry, in the financial sector in particular, and for research projects at the Universities of Dortmund and Leipzig. Volker Gruhn is a full professor at the computer science department of the University of Leipzig, Germany.

The purpose of entry criteria is to prevent a task from starting which would entail more wasted effort compared to the effort needed to remove the failed entry criteria. In principle test cases are designed to cover each partition at least once. The purpose of exit criteria is to prevent a task from being considered completed when there are still outstanding parts of the task which have not been finished.
Exit criteria are used by testing to report against and to plan when to stop testing.
For example, a system in failure mode may be characterized by slow operation, incorrect outputs, or complete termination of execution. Failure Mode and Effect Analysis FMEA : A systematic approach to risk identification and analysis of identifying possible modes of failure and attempting to prevent their occurrence. See also baseline. The measurement is independent of the technology.
This measurement may be used as a basis for the measurement of productivity, the estimation of the needed resources, and project control. See also black box test design technique. See also black box testing. The requirements are prioritized and delivered in priority order in the appropriate increment.
It involves recording incidents, classifying them and identifying the impact. They often have workflow-oriented facilities to track and control the allocation, correction and re-testing of incidents and provide reporting facilities. See also domain. See also input.

The most formal review technique and therefore always based on a documented procedure. See also portability. See also portability testing. This may be a manual guide, step-by-step procedure, installation wizard, or any other similar process description. It normally runs the installation process, provides feedback on installation results, and prompts for options.
An intake test is typically carried out at the start of the test execution phase. See also component integration testing, system integration testing. See also functionality testing. See also error tolerance. The keywords are interpreted by special supporting scripts that are called by the control script for the test. See also data driven testing. LCSAJ: A Linear Code Sequence And Jump, consisting of the following three items conventionally identified by line numbers in a source code listing : the start of the linear sequence of executable statements, the end of the linear sequence, and the target line to which control flow is transferred at the end of the linear sequence.

The software may include operating systems, database management systems, and other applications. See also output.
This implicitly means ongoing real-time code reviews are performed. Typically, they share one computer and trade control of it while testing. Pass: A test is deemed to pass if its actual result matches its expected result. See efficiency testing.

Load generation can simulate either multiple users or high volumes of input data. During execution, response time measurements are taken from selected transactions and these are logged.
Performance testing tools normally provide reports based on test logs and graphs of load against response times. Priority: The level of business importance assigned to an item, e. Direction and control with regard to quality generally includes the establishment of the quality policy and quality objectives, quality planning, quality control, quality assurance and quality improvement. This technique can be used for testing non-functional attributes such as reliability and performance.
See also reliability testing. It is performed when the software or its environment is changed. Some requirements management tools also provide facilities for static analysis, such as consistency checking and violations to pre-defined requirements rules. It includes outputs to screens, changes to data, reports, and communication messages sent out.
See also actual result, expected result. Examples include management review, informal review, technical review, inspection, and walkthrough. Reviewers can be chosen to represent different viewpoints and roles in the review process. The scribe has to make ensure that the logging form is readable and understandable. A daily build and smoke test is among industry best practices. See also intake test. See also N-switch testing. The tool checks source code, for certain properties such as conformance to coding standards, quality metrics or data flow anomalies.
See also operational profile testing. This information includes a listing of the approved configuration identification, the status of proposed changes to the configuration, and the implementation status of the approved changes. Stress testing: Testing conducted to evaluate a system or component at or beyond the limits of its specified requirements. It replaces a called component. Electronic Data Interchange, Internet. A technical review is also known as a peer review.
