First, modified cpn modeling is proposed as ct-cpn models to specify key characteristics and requirements for conformance testing scenario accurately. For example, ct-cpns models software functional behaviors according to software requirement specification, ct-cpnj models actual software implementation behaviors, ct-cpntp models software functional behaviors of specific test purposes, and ct-cpntc models finally generated test cases. Such ct-cpn series models explicitly specify external visible actions which are significant in practical test execution, that is, to make the most of both the place and the transition elements in ct-cpn models to distinguish visible actions from internal actions. In particular, to deal with the special output actions, such as the quiescence or deadlock , it introduces new kind of transitions to model them accurately. Besides, a corresponding implementation relation in the context of ct-cpn modeling is proposed as pn-ioco relation to precisely specify what it means for an implementation to conform to its functional specification.

In context of lts, the state space produced by synchronous product of two lts models tends to grow exponentially, which needs enormous even unpractical computation resources to generate suitable test cases. But, in context of cpn, synchronized model simulation based selection approach is irrespective of their model scale, so it just needs linear computation cost to produce feasible test cases. The effectiveness and practicability of our test selection method are enhanced with better scalability.

Other reasons for this extension are population data mismatch issue and difficulty in accessing the registration website. Special asn registration through official schools, he said, was opened through each school which was covered by eight agencies or ministries. So, registration can be done through the eight ministries or institutions that oversee the school. After the selection process is completed, the stage is continued with the announcement of graduation in november.

The application of the merit system in the regulation of the placement of high-ranking officials of civil servants is a necessity and a joint task of all parties, including the community itself. From the above analysis, we could see that test case models generated using our test selection method are quite feasible for guiding actual test execution intuitively and also effective for finding various implementation faults. According to testing results, conformance relation between a specific implementation and its specification model could be accurately determined. Third, in section 6, we prove the soundness of test generation; that is, as long as the software implementation fails one test case, it will definitely not conform to its functional specifications.

In original ioco testing theory, labeled transition system is utilized as its basic formal models. However, compared with lts or other formal modeling methods such as automata or process algebra, colored petri nets have more advantages for specifying and validating complicated functional behaviors of network software systems. First, cpn could not only specify the detailed and complicated software functionalities intuitively and hierarchically but also support visible simulation and efficient analysis to validate the correctness of software behaviors. Second, cpn models can execute dynamically, which is directed by the data-dependent control flow of system behaviors. Generating test cases by such model simulation process, they certainly contain actual test data and test oracles, so they are quite feasible for guiding practical test execution.

“information from bkn is always broadcasted through official news via bkn.Go.Id and through official bkn social media,” bayu said, wednesday, october 24. This proves that those who prepare early, especially with kitalulus teaching, have the opportunity to be able to pass the link pendaftaran cpns 2021 selection up to twice . Until now, kitalulus has taught more than 50,000 students at webinar sessions held and thousands of students have passed and been officially appointed as civil servants thanks to the guidance of kitalulus in 2020. In addition, students can also do interactive question and answer with kitalulus alumni, listen directly to experiences facing the cpns selection, prepare documents, question material to be tested, to tips and tips from kitalulus alumni. Kitalulus, a technology-based start-up that is engaged in education for the preparation of cpns and pppk selections, is here to support those who want to pursue a career as a state civil apparatus .

Thus, we need to add some necessary guard functions towards input or output transitions in the test purpose model to guarantee such behavior path be executed as expected. It is well demonstrated in section 5.4 through the practical test selection to a file sharing software system. In section 3, we mention that, based on ct-cpn modeling and pn-ioco relation, a novel test selection method should be developed with two desired goals. One is to make such test selection with high scalability for dealing with more complicated system models, and the other one is to make all test cases feasible for practical test executions.
