Explanation:

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

Correct Answer: Quality control

Correct Answer: Test Implementation and execution

Correct Answer: a) Quality Assurance Quality assurance is an activity that establishes and evaluates the processes that produce products Quality assurance would measure processes to identify weaknesses and then correct them to continually improve the process: Eg Code review b) Quality Control Quality control is a process in which the product's quality is compared with standards and corrective actions taken if required Quality control activities focus on identifying defects in the actual products produced Eg Testing c) Test Case A test case is a unit level document describing the inputs, steps of execution and the expected result of each test condition for every requirement from the BRD Testers determine whether the application is working correctly or not based on the test case that is being executed A test case is marked as "Pass" if the application works as expected and is marked as "Fail" if otherwise Test cases also aide in generating test status metrics d) Test Condition Test condition is the condition on which the test execution evaluates to pass or fail Eg of a test condition: Set Password field should accept a mix of Alphanumeric and Special characters on mandatory basis and throw error message otherwise e) Test Script Test script is the set of instructions performed on the application to verify its functions f) Test Data Test data is the input data used to test a particular functionality Eg: Username and password to test a login screen g) Test Bed Test bed is the environment on which the testing is done and includes the software and hardware set up that is required for testing the application

Correct Answer: The main task of Software Quality Assurance Group is to examine the overall s/w development process and to create and enforce standards and methods to improve it with the goal of preventing bugs from ever occurring With this definition, it is imperative that the QA helps an organization in continuous performance improvement and strive for perfection

Correct Answer: Key Challenges of s/w testing: 1 Testing considered late in project 2 Requirements not testable 3 Integration is done after all components have been developed: This might result into full testing not being covered 4 Complete testing is not possible

Correct Answer: Glass Box (or white box) testing is the process of giving i/p to the system and checking how the system processes i/p to generate o/p Black Box testing is the process of giving i/p to the system and checking if the system is giving correct o/p without bothering how the o/p is generated As we can see from the definitions, the role of black box testing is to ensure that the o/p generated is correct And role of white box testing is to ensure that methods used to generate the o/p are correct

Correct Answer: I have used following 4 types of Methodologies: 1 Boundary value analysis 2 Equivalence partitioning 3 Error guessing 4 Cause effect graphing

Correct Answer: While a test plan is being created, risks involved in testing the product are to be taken into consideration along with possibility of their occurrence and the damage they may cause along with solutions; if any Detailed study of this is called as Risk Analysis Some of the risks could be: New Hardware New Technology New Automation Tool Sequence of code delivery Availability of application test resources Identify and describe the risk magnitude indicators: High, Medium and Low High magnitude means the effect of the risk would be very high and non-tolerable Company may face severe loss and its reputation is at risk Must be tested Medium: tolerable but not desirable Company may suffer financially but there is limited liability or loss of reputation Should be tested Low: tolerable Little or no external exposure Little or no financial loss Company?s reputation unaffected Might be tested Three perspectives of Risk Assessment: Effect, Cause and Likelihood To assess risk by Effect, identify a condition, event or action and try to determine its impact To asses risk by Cause is opposite of by Effect Begin by stating an undesirable event or condition and identify the set of events that could have permitted the condition to exist To asses risk by Likelihood is to determine the probability that a requirement will not be satisfied
