Question 1

Software testing

Answer 1

is a way to assess the quality of software and reduce the risk of software failure in operation

Question 2

A common misperception

Answer 2

1. Testing only consist of execution of test

2. Testing only verify product

Question 3

Objectives of testing

Answer 3

1. To evaluate work products such as requierments, code, design, user stories
2. To verify that all requirments have been fullfilled.
3. To validate that test object is complete and works as the users and stakeholders expect
4. To build confidence in level of the quality of test object
5. To prevetn defects
6. To find failure and defects
7. To give sufficient informantion to stakeholders, to allow them to make informed decision about the level of quality
8. To reduse the level of risk of inadequate software quality
9. To comply with regularatory, legal, contractual requirments or standarts and to verify the test object’s compliance with such requirments or standarts

Question 4

Seven testing priciples

Answer 4

1. Testing show presence of defects, not that system free from bugs
2. Excaustive testing is impossible
3. Early testing or shift left testing
   4 clustering of bugs
   5 pestecide paradox
   6 testing is contex dependant
   7 error absence fallacy

Question 5

Debugging

Answer 5

is the development activity that finds, analyzes, and fixes such defects

Question 6

Test process

Answer 6

1. Test planing
2. Test monitoring and control
3. Test analysis
4. Test desighn
5. Test implementation
6. Test execution
7. Test completion

Question 7

Activities of Test planing

Answer 7

1. define the objectives of testing
2. define approaches for meeting test objectives within constraints imposed by the context
   documents: Test plans

Question 8

Activities of Test monitoring and control

Answer 8

1. on-going comparison of actual progress against the test plan, using any test monitoring metrics defined in the test plan
2. taking action necessary to meet the objectives of the test plan
   documents: Test progress reports

Question 9

Activities of Test Analysis

Answer 9

1. Analyzing test basis
2. Finding defects
3. Define features and sets of features to be tested
4. Define and prioritizing test conditions for each feature based on analysis of the test basis
5. Capturing bi-directional tracebility between each element of the test basis and teh associated test conditions

Question 10

Test conditions

Answer 10

the aspect of test basis, that is relevant to order to achieve specific test objectives

Question 11

Test suite

Answer 11

A set of test cases or test procedures to be executed in a specific test cycle

Question 12

Test case

Answer 12

A set of preconditions, inputs, actions, expected results and postconditions, based on test procedures

Question 13

Test procedure

Answer 13

A sequence of test cases in execution order, and any associated actions that may be required to set up the initial preconditions and any wrap up activities post execution.

Question 14

Activities of Test design

Answer 14

1. Designing and prioritizing test cases and sets of test cases.
2. Identifying necessary test data to support test conditons and test cases
3. Designing test environment and identifying any required infrastructure and tool
4. Capturing bi-directional tracebility between test basis, test conditons, test cases, and test procedures

Question 15

Activities of Test Implementation

Answer 15

1. Developing and prioritizing test procedures, and potentially creating automated test scripts.
2. Creating test suites
3. Arranging test suites withing the test schedule
4. Building test environment
5. Preparing test data and ensuring it is properly loaded in test environment
6. Capturing bi-directional tracebility between test basis, test conditions, test cases, test procedures, test suites

Question 16

Actitivities of Test execution

Answer 16

1. Rcording the ID’s and version of the test item or test object , test tool , and testware
2. Executing test
3. Comparig actual result with expected result
4. Analyzing anomalies
5. Reporting defects
6. Logging the outcome of test execution
7. Verifying bi-directional traceability

Question 17

Activities of Test completion

Answer 17

1. Checking whether all defects are closed
2. Creating test summary report
3. Finalizing and archiving the test environment, the test data, testware for later reuse
4. Handing testware other
5. Analyzing lessons learned
6. Using information to improve test process maturity
