Week 7 Flashcards
True or False? Test planning is only needed for system testing
False
True or False? System test planning involves both an understanding of the test objectives and the constraints.
True
Which of the following is not a component of a system test plan?
Set of test cases and their expected results.
Specification of the test environment
Schedule
Test Strategy
Set of test cases and their expected results.
True or False? A PERT chart helps document dependencies in a test schedule.
True
Given the following PERT chart, what is the minimum time to complete this project with only one person working?

True or False? A good way to encourage participants to commit to a schedule is provide them with an opportunity to help develop the schedule
True
Which of the following is not an approach for developing test estimates?
Using historical data
Estimating the number of expected defects
Using a percentage of the development estimate
Using a cost estimation model
Estimating the number of expected defects
True or False? Size and complexity of a system affect the time needed to test it.
True
True or False? POFA (pass of first attempt) provides an early indication of the quality of code.
True
True or False? Effort estimation can take part before, concurrently, or after size estimation.
False
True or False? A work breakdown structure (WBS) helps in bottom up estimation
True - A WBS helps to organize the parts that were broken down during bottom up estimation.
Which of the following is not a strategy for checking if an estimate is correct?
Randomly selecting estimates based on personal assumptions
Discussing with other experts
Looking at historical data
Checking that estimates for similar parts of a product are the same
Randomly selecting estimates based on personal assumptions
True or False? It is good to test high risk areas early, but they do not need to be tested thoroughly.
False
True or False? Testing should be prioritized based on the risk exposure.
True - Risk exposure is the probability of an adverse event occurring multiplied by the consequences. If this value is high, it should be tested first.
True or False? Using historical data to predict defect density may not always lead to accurate predictions.
True
True or False? Defect seeding is typically used with operational profiles.
False
Given the following example, how many defects are estimated to be remaining?
Assume Group X found 20 defects and Group Y found 10 defects. 5 defects were common to both Group X and Group Y. What is the estimated remaining defects?
40

True or False? Good test cases ideally map back to requirements and have their own identifiers.
True
True or False? Severity reflects the customer impact of the error.
True
What is not included in a test incident report description?
Attempts to repeat
Expected results
Priority of the defect
Date and time
Priority of the defect - Defect priority is not set by the tester who finds the problem but is a management decision.
Which of the following is not a part of a test summary report?
Recommendations for improving the testing process
Summary of what was tested
Comprehensive assessments
Evaluation
Recommendations for improving the testing process
When should system test planning begin?
Testing Phase
Design Phase
Development Phase
Requirements Phase
Requirements Phase
Which of the following is not included in a system test plan?
Test Objectives
Schedule
Test cases
Risk Management
Test cases
Given the following PERT chart, what is the minimum time to complete this project based on the critical path? 16 13 21 17
16
True or False? Having a list of effort and resources needed to perform tasks is not required when creating a test schedule.
False
True or False? One should utilize an estimate of POFA (pass of first attempt) to estimate overall system testing time.
True
True or False? Identifying all of the testing tasks requires thoroughly understanding the requirements.
True
Which of the following is not a reason for inaccurate estimates?
Losing personnel
Overlooked tasks
Lack of historical data
Lack of analysis when developing estimates
Losing personnel
True or False? Contingency plans should be written for all risk items.
True
False
False
Which of the following is not a curve used to analyze software readiness?
Remaining defects in the software
Mean time to failure
Number of failures per unit of time
Failure intensity
Remaining defects in the software
True or False? High severity errors implies high priority errors.
False
