Quality Assurance FDT Test and Certification Background

Quality Assurance FDT Test and Certification

Background – FDT Specification I n All work together n FDT Specification defines how products from different manufacturer work together n Prove in practice n The theoretical possibility must be proved in practice n Demand for guarantee n Customers require a maximum of guarantee for the interaction of products from different vendors n Certification of the products can give a guarantee

Background – FDT Specification II n Tested independently n Before a product gets the certification it must be tested independently n Product matches specification n The independent test checks if the product matches with the specification in all points n Interoperability is a major objective of FDT

Background – Vendor test n Tests necessary ■ Vendor specific tests are also necessary n Not recognized n Sometimes errors can not be recognized by vendor specific tests due to ■ Different and wrong interpretation of the specification ■ Incomplete or wrong implementation n Independent test n These kind of errors should be found during an independent test n Tools to perform the independent tests

Background – Development support I n Verify n The developer of a DTM or Frame application needs support to check his DTM or Frame against the FDT specification. n From early beginning on n The FDT conformity check should begin as soon as possible within the development process. n Logging n The tools provides extensive logging capabilities. n Close to source code n If there are errors in the software implementation, the developer will be navigated near to their locations in the source code.

Test Scope n In scope n DTM or Frame application fulfils the FDT Specification n Out of scope n Functional tests of the DTM or the Device n Extendable n The official test scripts can be extended by the manufacturer to cover also product specific tests n These tests are not relevant for certification tests n (Semi-) automated software tests can be performed

Types of the Test n Good cases n Test flow with variation of parameters and variation of method calls, which are in scope of the FDT-Specification n Bad cases n “Bad behavior” which is in scope of the FDT-Specification, e. g. communication errors n Robustness cases n Parameters or a sequence of method calls will be used, which are not conform to the FDTSpecification

Types of the Test (Optional) n Style Guide Test n Conformity test of GUI related attributes defined by the FDT specification

Certification Process

Certification Process - Details n At first a manufacturer develops a DTM or a frame application and puts these through extensive tests, potentially already making use of our test tools for inhouse tests. Following this initial phase a manufacturer then arranges the conditions of the conformity test with the test laboratory. n Next, the test laboratory conducts the tests according to the rules laid down by the FDT Group and then issues a test report. The test report is then being given to the manufacturer. If in testing it turns out that there are still deviations from the conformity, the test laboratory will consult with the manufacturer in great detail. It is this consulting service that constitutes a real benefit for the manufacturer, because he now can eliminate the deficiency and resubmit the DTM for testing. n After a positive test the manufacturer can submit the test report to the certification office and apply for a certificate. Optionally the certified product can be listed on the FDT Group homepage. http: //www. fdt-group. org/en/05 e_zerti/ze-02_prozess. html
