Correct Answer: Risk analysis is a method to determine how much risk is involved in something In testing, it can be used to determine when to test something or whether to test something at all Items with higher risk values should be tested early and often Items with lower risk value can be tested later, or not at all It can also be used with defects Severity tells us how bad a defect is: "how much damage can it cause?" Priority tells us how soon it is desired to fix the defect: "should we fix this and if so, by when?" Defects with High Severity and Priority are tested first

Correct Answer: Capability Maturity Model (CMM) is a model of 5 levels of process 'maturity' that determine effectiveness in delivering quality software The 5 levels of CMM are described as below: Level 1: Initial: - characterized by chaos, periodic panics, and heroic efforts required by individuals to successfully complete projects Very few or none of the processes are in place Level 2: Repeatable: - Software Project Tracking, Requirements Management, Realistic Planning and Configuration Management Processes are in place; successful practices can be repeated Level 3: Defined: - Standard Software Development and Maintenance Processes are integrated throughout an organization A Software Engineering Process Group is in place to oversee software processes, and training programs are used to ensure understanding and compliance Level 4: Managed: - Metrics are used to track productivity, processes, and products Project performance is predictable, and quality is consistently high Level 5: Optimizing: - The focus is on continuous process improvement The impact of new processes and technologies can be predicted and effectively implemented when required Any organization can start from any level, but its motto is to reach level 5; where the focus is continuous process improvement By doing this, high quality s/w delivery is assured From this, we can see that the whole essence of CMM or CMMI is to produce quality software It targets the whole organizational practices (or processes), which are believed to be the best across industries Testing is part of Quality Assurance CMM levels play an important role in an organization?s Quality Assurance effort Thus testing plays an important role in determining CMM level

Correct Answer: Integration testing is done at module level when various modules are integrated with each other to form a system or sub-system Its main purpose is to ensure that interfaces between various modules are working properly; ie modules which are working individually are also working correctly together System testing is done on a complete, integrated system to evaluate the system?s compliance with its specified requirements It validates that the system meets its functional and non-functional requirements From these definitions, it is clear that the purpose of Integration and purpose of System Testing are different Therefore, Integration test cases focus more on the interfaces between modules (interface integrity) - the data transfer and their interaction with each other System test cases focus on testing the product as a whole; ie whether the functional, non-functional requirements of the System are met or not Since System Testing is the final phase before delivery of the product, System test cases should pinpoint configuration related errors along with testing for performance, security, reliability etc

Correct Answer: Testing is a process used for revealing defects in s/w and for establishing that the s/w has attained a specific degree of quality The s/w testing group?s main objective is to ensure that the s/w is doing what it is supposed to do as well as the s/w is not doing what it is not supposed to do With this objective, it is clear that it is necessary to have a separate group for testing the s/w other than the group which developed it Also, bugs in the s/w can cause severe monetary as well as other loss to the organization So it is important to allocate some budget for the testing group

Correct Answer: BackTracking

Explanation:

BackTracking is used for solving N-Queens problem

Correct Answer: Test Implementation and execution

Correct Answer: Quality control

Correct Answer: The use of data on paths through the code

Explanation:

Data flow analysis studies the use of data on paths through the code.

Correct Answer: DCL

Explanation:

Data Control Language takes caare of security and authorization

Correct Answer: The word assurance means ?guarantee? So the Quality Assurance Group?s role is to guarantee that the product is of high quality They examine the overall s/w development process and their responsibility is to create and enforce standards and methods to improve it with the goal of preventing bugs from ever occurring
