It is used to test the functionality and compatibility of the module being tested. The driver provides the necessary inputs and calls the functions or methods of the module being tested, allowing the tester to observe and evaluate its behavior and output.

The correct answer is "Sendvic integracija, Integracija od dna ka vrhu." Sendvic integracija refers to the process of integrating components that have passed unit testing into a single system for further testing. Integracija od dna ka vrhu means integrating from the bottom up, starting with the lower-level components and gradually adding higher-level components. Both approaches are commonly used in software development to ensure that all components work together effectively.

The correct answer is Integracija po principu velikog praska and Integracija od vrha ka dnu. These two strategies involve integrating components that have passed unit testing into a single system for further testing. Integracija po principu velikog praska refers to integrating all components at once, simulating a "big bang" approach. Integracija od vrha ka dnu, on the other hand, involves integrating components from the top of the system hierarchy downwards. Both strategies aim to ensure that the integrated system functions correctly and can be effectively tested.

Regresivni testovi se koriste više puta i proveravaju da li je došlo do lošeg rada funkcija koje nisu obuhvaćene konkretnom izmenom. Ovo znači da se ovi testovi koriste za proveru da li su prethodno ispravne funkcionalnosti i performanse sistema ostale netaknute nakon izvršenja promena ili dodavanja novih funkcionalnosti.

During the software maintenance phase, the team provides information about the system and identifies and resolves causes of failures. They are responsible for gathering and sharing knowledge about the system to ensure smooth operation and efficient problem-solving. Additionally, they investigate and fix any issues or malfunctions that may occur, ensuring the system's proper functioning.

To verify if a programmer has correctly interpreted the design while writing code, a special code review group is formed. This group uses two methods: Letimicni pregled (quick review) and Inspekciju koda (code inspection). These methods involve reviewing the code for correctness and adherence to design principles. The other two options, Objektivni pregled (objective review) and Detaljni pregled (detailed review), are not mentioned as methods used by the code review group in this context.

The given answer states that the techniques developed using the method of black box testing are decision coverage and condition coverage. Decision coverage involves testing each possible decision outcome, while condition coverage involves testing each possible condition within a decision. These techniques help ensure that all decisions and conditions in the code are tested, increasing the overall test coverage and reducing the risk of undiscovered errors.

Capacity testing is a type of performance testing that evaluates how a system handles large amounts of data. It checks the system's ability to process and manage a high volume of data without any performance degradation or failure. This type of testing helps identify any bottlenecks or limitations in the system's processing capabilities and ensures that it can handle the expected workload efficiently.

The choice of data structure affects the complexity of the program because different data structures have different time and space complexity for various operations. The complexity of the program can be influenced by the efficiency of the chosen data structure in performing operations such as insertion, deletion, and searching. Additionally, the choice of data structure can be taken from the design phase of the program, where the requirements and constraints are analyzed, and the appropriate data structure is selected based on those factors.

The given answer states that the techniques developed using the black box method are "Podela na klase ekvivalencije" (Equivalence partitioning) and "Uzrocno-posledicni graf" (Cause-effect graph). Equivalence partitioning involves dividing the input data into groups or classes that are expected to exhibit similar behavior, allowing for a more efficient and effective testing process. Cause-effect graphing, on the other hand, involves creating a graphical representation of the cause-effect relationships between different variables, helping to identify the most critical test scenarios. These techniques are commonly used in functional testing to ensure comprehensive test coverage and identify potential defects.

Metodi bele i crne kutije se sprovode u okviru jediničnog testiranja. Jedinčno testiranje je proces testiranja pojedinačnih komponenti ili modula softvera kako bi se proverila njihova ispravnost i funkcionalnost.

The correct order of the four phases of software testing is: 1) Izrada plana testiranja (Test plan creation), 2) Specifikacija testova (Test specification), 3) Realizacija testiranja (Test implementation), and 4) Evaluacija rezultata (Results evaluation). This order ensures that the testing process is systematic and follows a logical flow, starting with planning and specifying the tests, then executing them, and finally evaluating the results obtained.

The correct answer is "Letimicni pregled" because it refers to a quick review or a cursory examination of the code. In this method, the programmer presents the code, and then a discussion takes place to identify any errors or issues. It is a less detailed and comprehensive review compared to other options such as "Detaljan pregled" (detailed review) or "Inspekcija koda" (code inspection). "Prezentacioni pregled" does not accurately describe the process of reviewing the code.

The answer states that the performance or effectiveness of a test is calculated as the ratio of the number of errors found in a given test to the total number of errors discovered. This means that the answer is referring to the ratio of the errors found to the total number of errors, which is a measure of how well the test was able to identify and detect errors.

The correct answer is "Upustvo za operatera" and "Upustvo za instalaciju". This is because when a software product is delivered, it is important to provide documentation that guides both the operator and the installer. The "Upustvo za operatera" provides instructions and guidance for the person who will be using and operating the software, while the "Upustvo za instalaciju" provides instructions on how to properly install and set up the software. These two documents are essential in ensuring that the software is used correctly and efficiently.

After making changes to hardware, software, or the working environment, it is necessary to implement secondary changes in the software. This activity is called adaptive maintenance.

The final phase is installation testing, where the system is tested to ensure it can be successfully installed and deployed.

The correct answer states that one test case can be applied to multiple legal equivalence classes, while a separate test case is needed for each illegal equivalence class. This implies that the goal of the method is to maximize test coverage by using as few test cases as possible. By applying one test case to multiple legal equivalence classes, we can ensure that different variations within the same equivalence class are covered. On the other hand, each illegal equivalence class requires a separate test case because they represent distinct and potentially unique scenarios that need to be tested individually.

The customer can perform acceptance testing within the framework of system testing through parallel testing and pilot testing. Parallel testing involves running the new system alongside the old system to compare their results and ensure the new system is functioning correctly. Pilot testing refers to testing the system with a small group of end users before rolling it out to the entire organization. These methods help ensure that the system meets the customer's requirements and is ready for deployment.

The efficiency of testing is measured by the ratio of the number of errors found during testing to the effort put into that testing.

After completing the training, administrators should be able to help end users if they encounter any irregular situations while using the software and establish conditions for the normal operation of the system.

The correct answer states that if the input or output condition represents a range of values, tests should be written for the ends of the range and for values immediately adjacent to the ends. This means that when testing a condition that has a range of possible values, it is important to test the minimum and maximum values of the range, as well as values that are just outside of the range. This ensures that the program is tested thoroughly and can handle all possible values within the range.

The given correct answer is "Pokrivanje uslova". This refers to the testing technique where each elementary component of a complex condition takes a value from both the allowed and forbidden set of values. This technique helps in ensuring that all possible conditions and combinations are tested, increasing the overall test coverage.

By intentionally introducing errors into the code and then running tests, the method allows developers to assess the effectiveness of their error detection and correction mechanisms.

The correct answer is "Jedinicnog i integracionog testiranja" which translates to "Unit and integration testing" in English. This explanation suggests that the verification of a software system is done through both unit testing, which focuses on testing individual components or units of code, and integration testing, which tests the interaction between different components or units. This combination of testing techniques ensures that both the individual units and their integration within the system are functioning correctly.

The correct answer is "Prvo testira najvazije komponente, Moze da bude po sirini i po dubini." This is because the given statement implies that integration testing is performed starting from the topmost components and moving towards the lower ones. It also mentions that the testing can be done either breadth-first or depth-first.

The correct answer is "Planu testiranja". The question asks about the description of the process of testing, including unit, integration, and system testing. The plan for testing is where this description would typically be outlined, as it provides a detailed approach for conducting testing activities, including the different types of tests to be performed. The organizational plan may provide a broader overview of how testing fits into the overall project, but it may not provide the specific details of the testing process. The specification of tests would focus more on the individual tests themselves, rather than the overall process. The project requirements may mention the need for testing, but they would not describe the testing process in detail.

The evaluation of test results can be done by measuring the performance or effectiveness of the test and by measuring the efficiency of the testing phase. This means that the effectiveness and efficiency of the test can be measured to determine the quality of the results.

The method of partitioning into equivalence classes has the property of classifying input data into representative equivalence classes. It also forms mutually disjoint equivalence classes.

The correct answer states that control structures should be chosen in a way that avoids large jumps in the program and that control structures manage the flow of program execution. This means that control structures should be designed and implemented in a way that allows for smooth and efficient execution of the program, without abrupt or unnecessary jumps in the flow. Control structures play a crucial role in directing the flow of execution and ensuring that the program behaves as intended.

Installation testing in the context of system testing involves allocating necessary files and configuring the system according to the environment. This means that during installation testing, the focus is on ensuring that the required files are properly allocated and the system is configured correctly to work in the given environment. The other options mentioned, such as documentation creation and simulating everyday system work, are not directly related to installation testing.
