věrná kopie

věrná kopie, někdy označovaná také jako “věrná kopie”, je specifická testovací technika, která se používá v softwarovém testování k ověření správnosti a konzistence softwarového systému. Spočívá v porovnání výstupů dvou různých implementací stejného softwarového komponentu nebo funkce a zajištění, že poskytují stejné výsledky.
Existují různé přístupy k provádění věrného kopírování v závislosti na cílech testování a architektuře systému. Níže jsou uvedeny některé běžné metody:
* **Paralelní implementace:** Vytvoří se dvě nezávislé implementace stejné softwarové funkce nebo komponenty. Tyto implementace se spustí paralelně a jejich výstupy se porovnají, aby se zjistily případné rozdíly.
* **Střídání implementací:** Jedna softwarová implementace se spustí dvakrát a výstupy z prvního spuštění se použijí jako vstupy pro druhé spuštění. To umožňuje odhalit problémy s konzistencí ve výstupech implementace.
* **Výpočet kontrolních součtů:** Kontrolní součty se vypočítají pro výstupy různých implementací a porovnají se, aby se zjistila jejich shoda. Kontrolní součty jsou hodnoty, které stručně reprezentují sadu dat, a jakékoli změny ve výstupech způsobí změnu kontrolního součtu.
Věrná kopie je účinná technika pro odhalování:
* **Logické chyby:** Chyby, které vedou k nesprávným nebo nekonzistentním výsledkům.
* **Chyby souběžnosti:** Chyby, které se objevují při souběžném spouštění více vláken nebo procesů.
* **Chyby v numerických výpočtech:** Chyby, které vedou k nepřesným nebo nesprávným numerickým výsledkům.
Věrná kopie se široce používá při testování kritických softwarových systémů, jako jsou systémy řízení letového provozu, bankovní systémy a systémy zdravotní péče. Pomáhá zvyšovat důvěru ve správnost a spolehlivost softwaru tím, že odhaluje skryté chyby a problémy s konzistencí.

Test Environment

The test environment is a critical component of the validation master plan, as it defines the infrastructure and resources required to execute the test cases and evaluate the results. It should ensure that the testing is conducted in a controlled and repeatable manner, and that the results are reliable and accurate.

• Hardware and Software Requirements: Specify the hardware and software configurations required to run the test cases, including operating systems, processors, memory, storage, and network connectivity. This ensures that the test environment is compatible with the software being tested and that the test results are not affected by environmental factors.
• Test Data Management: Define the strategies for managing test data, including data creation, storage, and retrieval. This ensures that the test cases have access to the necessary data to perform the tests and that the data is managed consistently throughout the testing process.
• Security and Data Protection: Establish security measures to protect the test environment and data from unauthorized access and modification. This includes defining user roles and permissions, implementing firewalls and intrusion detection systems, and backing up critical data.
• Test Environment Monitoring: Define the procedures for monitoring the test environment to ensure that it is functioning properly and that there are no performance issues or errors. This may involve using monitoring tools to track system resources, application logs, and network traffic.

By carefully planning and managing the test environment, organizations can ensure that the validation testing is conducted in a controlled and reliable manner, leading to accurate and meaningful results.

Test Cases

Test cases are a fundamental component of the validation master plan, as they define the specific tests that will be executed to verify and validate the software system. Each test case should be designed to evaluate a specific requirement or functionality of the software, and should include the following elements:

• Test Case ID: A unique identifier for the test case that allows for easy referencing and tracking.
• Test Case Description: A clear and concise description of the test case, including the objective of the test and the steps required to execute it.
• Expected Results: The anticipated outcome of the test case, which may include specific values, behaviors, or states.
• Actual Results: The observed outcome of the test case, which should be compared against the expected results to determine the pass/fail status.
• Test Case Status: The outcome of the test case, typically indicated as “Pass” or “Fail”.
• Test Case Priority: The level of importance or urgency associated with the test case, which may be used to prioritize test execution.

By carefully defining and managing test cases, organizations can ensure that the validation testing process is thorough and effective, and that all critical aspects of the software system are evaluated.

Traceability Matrix

A traceability matrix is a critical component of the validation master plan, as it provides a systematic way to track and manage the relationships between software requirements, test cases, and defects. It ensures that all requirements are covered by at least one test case and that all test cases are traceable to specific requirements.

• Requirement Coverage: The traceability matrix helps to ensure that all software requirements are covered by at least one test case. This ensures that the validation process is comprehensive and that no critical requirements are overlooked.
• Test Case Coverage: The traceability matrix also ensures that all test cases are traceable to specific software requirements. This allows for easy identification of the requirements that are covered by each test case, and helps to prevent the creation of unnecessary or redundant test cases.
• Defect Tracking: The traceability matrix can be used to track defects and their resolution. By linking defects to the corresponding requirements and test cases, it is possible to identify the root cause of defects and ensure that they are addressed effectively.
• Change Management: The traceability matrix can also be used to manage changes to software requirements and test cases. By tracking the impact of changes on related requirements and test cases, it is possible to maintain the integrity and consistency of the validation process.

By implementing a traceability matrix, organizations can improve the efficiency and effectiveness of their validation process, ensure comprehensive coverage of software requirements, and facilitate defect tracking and change management.

Validation Schedule

The validation schedule defines the timeline for the validation activities, including the start and end dates for each phase of testing. It should be realistic and achievable, taking into account the complexity of the software, the available resources, and the project deadlines.

The validation schedule should consider the following factors:

• Software Development Schedule: The validation schedule should be aligned with the software development schedule to ensure that testing activities commence at the appropriate time.
• Resource Availability: The schedule should take into account the availability of testing resources, such as testers, test environments, and test tools.
• Project Deadlines: The validation schedule should be developed in conjunction with the project deadlines to ensure that the software is ready for release on time.

An effective validation schedule helps to ensure that the validation activities are completed on time and within budget. It also provides stakeholders with a clear understanding of the progress of the validation effort.

Resources

The resources section of the Validation Master Plan (VMP) identifies the personnel, equipment, and facilities required to conduct the software testing and quality assurance activities. These resources should be carefully planned and managed to ensure the success of the project.

• Personnel Resources: The VMP should identify the number and qualifications of the personnel required to conduct the testing activities. This may include test инженéři, test analysts, and quality assurance specialists.
• Equipment Resources: The VMP should also identify the equipment resources required for testing, such as test equipment, software tools, and test fixtures.
• Facilities Resources: The VMP should identify the facilities resources required for testing, such as test laboratories, test harnesses, and environmental chambers.

Adequate resources should be allocated to the testing activities to ensure that they are conducted in a timely and efficient manner. Insufficient resources can lead to delays, lower test coverage, and a reduction in the quality of the final product.

Acceptanceイツ

The acceptance criteria define the conditions that must be met in order for the software to be considered acceptable for release. These criteria should be clearly defined and agreed upon by all relevant parties, including the development team, the testing team, and the business users.

The acceptance criteria should be based on the software requirements and should cover both functional and non-функционал requirements. Some examples of acceptance criteria include:

* The software must be able to process a minimum of 100 transactions per second.
* The software must be able to generate reports in a variety offormats.
* The software must be able to interface with other systems without errors.

The acceptance criteria should be used to guide the testing activities and to ensure that the software meets the expectations of the end users.

Reporting and Communication

Reporting and communication are critical throughout the validation process to ensure that all stakeholders are kept informed of the progress and results of the testing activities. The Validation Master Plan (VMP) should define the reporting and communication channels that will be used, as well as the frequency and format of the reports.

The VMP should also identify the individuals or groups who are responsible for receiving and reviewing the reports, and the actions that should be taken based on the reported results. Regular reporting and communication help to ensure that any issues or problems are identified and addressed promptly, and that the validation process is proceeding as planned.

Change Management

Change management is an important aspect of the validation process, as it ensures that any changes to the software or test environment are properly documented, reviewed, and approved before being implemented.

• Change Control Process: The VMP should define a change control process that outlines the steps that must be followed when making changes to the software or test environment. This process should include a review and approval process to ensure that the changes are necessary and will not adversely affect the validation process.
• Change Impact Analysis: The VMP should also define a process for analyzing the impact of changes. This analysis should identify the potential impact of the changes on the software, the test environment, and the validation schedule.
• Change Implementation: The VMP should also define a process for implementing changes. This process should ensure that the changes are implemented correctly and that the software is tested to verify that it is still functioning as expected.
• Change Documentation: The VMP should also define a process for documenting changes. This documentation should include a description of the change, the rationale for the change, and the impact of the change. This documentation should be maintained throughout the validation process.

Effective change management helps to ensure that the validation process is not disrupted by unnecessary or uncontrolled changes. It also helps to ensure that the software is always in a validated state.
