The test is the most operationally important step in quality management. It marks the end of an entire series of quality control measures and is intended to verify the defined quality metrics.
Testers are methodically trained in the Specific Group for this purpose and ranked by experience: junior, middle, senior and lead. Lead testers have management experience appropriate to conducting a test team. The test procedure, the methodology, will be developed together with the client and adapted to meet his requirements.
Testers in the Specific Group are trained in the area of business analysis and requirement engineering, so as to be able to determine and implement a client's general requirements and tool/automation needs with clarity and precision. Next to the requirements specification and code, test cases are the third pillar of professional software development. Tests are structured in test cases, stages and cycles. Relevant software is helpful in this regard. Our experts can assist in the selection of appropriate software. Test data are supplemented for test cases. In this regard, efficiency is key to deciding whether these should be generated with tool support or created manually. Recurring tests are reviewed in terms of their suitability for automation. Tool utilization is effected based on prior operational analysis, to determine the best mix of manual and software supported testing in the client's particular case.
Errors found during the tests are reported by the tester. This assists fault management and bug tracking software.
Incidents and issues are qualified by the test manager (senior tester profile), and then sequenced and backed up by analysis and test data. Lastly, the possible impact on software development and the project can be estimated.
The following test stages are distinguished:
The documents test takes place in the form of a review immediately after delivery of the specifications, use cases and/or requirements by the client or business analyst.
The unit test is a step in quality assurance during code production. The aim is to develop a test code for each code and thus already identify the ACTUAL-TARGET variance at the functional, class and module levels.
The key figures concerning measurability of the test coverage of the code by means of test cases or of the measures and technologies employed will be checked out with the client.
Following test-driven development, unit tests will be written before actual software development.
Testing specialists are employed to run operational tests and tests of technical functionality. They will test the software/IT as users based on the requirements from written test cases, test descriptions and check lists from the preliminary stages.
The functional test usually starts with a smoke test. This test verifies whether a piece of software is ready for a test by using specially synchronised tests. The scope of a smoke test rarely exceeds one hour. The test is run in a development environment or a dedicated test environment. Functional tests focus on UI based user testing, but also on system tests without UI input.
The regression phase follows after requirements testing or tests of technical functionality. Regression testing is based on a defined set of test cases (also possibly a collection of functional tests/modules, integration or systems integration or end-to-end tests), which are carried out in order to check existing software paths. Automating regressions has the effect of increasing efficiency, depending on how frequently executed.
The aim of integration testing is verifying the interaction of interfaces and the interactions between different parts of software. Each component should by this time have completed the functional test runs.
System testing is performed on a fully integrated system to confirm the core requirements of the software. Each component and each module of the system should already have gone through the integration testing.
System Integration Testing
The system integration tests are used in testing the interactions required between systems that are integrated differently. Each participating system should at this point have already gone through system testing at this point.
We would moreover also be happy to advise you regarding environments to be implemented, process quality, quality assurance measures and additional topics associated with quality management.
Testing requirements can be determined at any time. The actions associated with it ensure your project is completed on time – just as you have planned.
