Software Testing for Distributed Systems‌ Testing with Use Cases and Test Cases Clause Samples

Software Testing for Distributed Systems‌ Testing with Use Cases and Test Cases. The approach to take uses cases (UCs) as a basis to generate test cases (TCs) is promising to launch the testing activities in a project at a very early stage of the development cycle. The advantage of this method is that the generation of test cases can begin before a single line of code is written and as a result the testing activities can accompany the whole project development cycle from the very start. While in the IoT6 project the testing process just started after initial achievements have been reached, the UCs described in deliverable D1.1 are still a very good opportunity to assess the functionality of the whole system and to create test cases in spite of components that are not yet fully developed. A UC is therefore defining the behaviour of a system, without necessarily referencing the internal structure, thus it can be seen as black-box approach. It can be used to model the external requirements on a subject (i.e. component) and further specify the functionality exposed by a subject. The focus lies on specifying behaviour that a subject can perform with one or more actors, while behaviours include interactions between actor and subjects which may result in state changes and communication with the environment. The creation of test cases is a basic step for software testing in any domain, as test procedures can be constructed from test cases from test automation, test scripts may be implemented. One aspect of test cases is the identification of conditions which have to be implemented and are necessary to verify the system requirements. As previously mentioned, TCs can be created as soon as the UCs are available, as for their generation only the external requirements are necessary. The most important part of a UC for generating TCs is the flow of events [6]. A typical UC consists of the basic flow, which more or less describes, what usually happens when the UC is executed and the alternate flow of events, which corresponds to the behaviour of exceptional- and optional events relative to the basic flow. In the presented scenarios for the IoT6 architecture, the usual flow of events was modelled, while in scenario 2 an optional flow is included for demonstration purposes. Use case scenarios are instances of a UC or in other words a complete path from start to termination of the UC. They may be seen as the basis for the creation of TCs. A test case (TC) is a set of inputs in combination with execution conditions and expected results, developed to exec...

  • Follow-up Testing An employee shall submit to unscheduled follow-up drug and/or alcohol testing if, within the previous 24-month period, the employee voluntarily disclosed drug or alcohol problems, entered into or completed a rehabilitation program for drug or alcohol abuse, failed or refused a preappointment drug test, or was disciplined for violating the provisions of this Agreement and Employer work rules. The Employer may require an employee who is subject to follow-up testing to submit to no more than six unscheduled drug or alcohol tests within any 12 month period.

  • Meter Testing Company shall provide at least twenty-four (24) hours' notice to Seller prior to any test it may perform on the revenue meters or metering equipment. Seller shall have the right to have a representative present during each such test. Seller may request, and Company shall perform, if requested, tests in addition to the every fifth-year test and Seller shall pay the cost of such tests. Company may, in its sole discretion, perform tests in addition to the fifth year test and Company shall pay the cost of such tests. If any of the revenue meters or metering equipment is found to be inaccurate at any time, as determined by testing in accordance with this Section 10.2 (Meter Testing), Company shall promptly cause such equipment to be made accurate, and the period of inaccuracy, as well as an estimate for correct meter readings, shall be determined in accordance with Section 10.3 (Corrections).

  • Laboratory Testing All laboratories selected by UPS Freight for analyzing Controlled Substances Testing will be HHS certified.

  • Loop Testing/Trouble Reporting 2.1.6.1 Telepak Networks will be responsible for testing and isolating troubles on the Loops. Telepak Networks must test and isolate trouble to the BellSouth portion of a designed/non-designed unbundled Loop (e.g., UVL-SL2, UCL-D, UVL-SL1, UCL-ND, etc.) before reporting repair to the UNE Customer Wholesale Interconnection Network Services (CWINS) Center. Upon request from BellSouth at the time of the trouble report, Telepak Networks will be required to provide the results of the Telepak Networks test which indicate a problem on the BellSouth provided Loop. 2.1.6.2 Once Telepak Networks has isolated a trouble to the BellSouth provided Loop, and had issued a trouble report to BellSouth on the Loop, BellSouth will take the actions necessary to repair the Loop if a trouble actually exists. BellSouth will repair these Loops in the same time frames that BellSouth repairs similarly situated Loops to its End Users. 2.1.6.3 If Telepak Networks reports a trouble on a non-designed or designed Loop and no trouble actually exists, BellSouth will charge Telepak Networks for any dispatching and testing (both inside and outside the CO) required by BellSouth in order to confirm the Loop’s working status. 2.1.6.4 In the event BellSouth must dispatch to the end-user’s location more than once due to incorrect or incomplete information provided by Telepak Networks (e.g., incomplete address, incorrect contact name/number, etc.), BellSouth will ▇▇▇▇ ▇▇▇▇▇▇▇ Networks for each additional dispatch required to repair the circuit due to the incorrect/incomplete information provided. BellSouth will assess the applicable Trouble Determination rates from BellSouth’s FCC or state tariffs.

  • Performance Testing (a) All performance tests of the Project, including any Initial Performance Test required in Section 2 of Appendix VIII, will be performed in accordance with the test procedures set forth in Appendix VIII (“Performance Test”), including additional procedures and protocols related to Performance Testing as mutually agreed between Buyer and Seller (“Test Procedures”). Seller shall bear all costs and receive all revenues, if applicable, associated with all Performance Tests. (b) After the Initial Delivery Date and during the Delivery Term, Buyer will have the right to conduct a Performance Test (“Buyer Performance Test”) no more than once a calendar year to demonstrate whether the Project is capable of delivering the Distribution Services at the Contract Capacity. Within 30 calendar days following a Buyer Performance Test, Seller will have the right to retest the Project with a Performance Test (“Seller Retest”). For the avoidance of doubt, the results of any Seller Retest will supersede the results of the preceding Buyer Performance Test. (i) If a Buyer Performance Test or, if a corresponding Seller Retest has occurred, a Seller Retest demonstrates the Project is capable of delivering Distribution Services at or above ninety-nine percent (99%) of the Initial Contract Capacity, the Contract Capacity will remain the Initial Contract Capacity; (ii) If a Buyer Performance Test or, if a corresponding Seller Retest has occurred, a Seller Retest demonstrates the Project is capable of delivering Distribution Services at more than or equal to eighty-five (85%) of the Initial Contract Capacity, but less than ninety-nine percent (99%) of the Initial Contract Capacity (“Testing Band”), the Contract Capacity will be automatically adjusted (upwards or downwards) to the capacity commensurate with the amount of Distribution Services the Project delivered during the Performance Test within the Testing Band. (iii) If a Buyer Performance Test or, if a corresponding Seller Retest has occurred, a Seller Retest demonstrates the Project is not capable of delivering Distribution Services of at least eighty-five percent (85%) of the Initial Contract Capacity, an Event of Default shall occur in accordance with Section 7.1(a)(viii).
