Q

Drivers

A
  • Code that sets up an environment and calls a module for test
  • causes the component under test to exercise the interfaces
  • as you move of the drivers are replace with the actual components

Q

The objectives of preventive, defective, and corrective are:

A
  • assure all authorized transactions are completely processed once and only once
  • assure transaction data is complete and accurate
  • assure transaction processing is correct
  • assure that processing results or utilize for the intended benefits
  • assure that the app can continue to function

Q

Test data key considerations

A
  • ensure the test data represents real world use

Q

Metric

A

A Software metric is a mess not a phone number that shows the relationship between two measures

22
Q

Selective regression testing

A

The process of testing only those sections of a program where the testers analysis indicates programming changes have taken place and the related component

23
Q

Should test data be backed up prior to first to use?

24
Q

Test data management

A

A defined strategy for the development, used, maintenance, and ultimately destruction of test data
ex: analysis, Design, creation, used, maintenance, destruction

25
Test data
- Data points required to test most apps - helps confirm expected results - verify software behaves correctly for invalid input data
26
challenges with using commercial off the shelf (COTS)
- task or items missing - software fails to perform - extra feature - doesn’t meet business needs. operational needs, or peoples needs
27
commercial off-the-shelf | COTS
-commercial off-the-shelf software products that are ready made in available for sale in the marketplace
28
regression testing should occur when the following conditions are met:
-New releases of software -changes or enhances made to the app -support software changes -either side of a system interface is changed -changes to config -changes made after testing stage is complete
29
Acceptance testing
determine throughout the dev cycle that all aspects of the development process meets the users needs -Done throughout the lifecycle
30
Defect management
- prevent defects - Risk driven - integrate - automated - process improvement emphasized - Evaluate the process
31
What is included in defects?
- defect name - defect severity - defect type - defect class
32
what are the disadvantages of using test data from Prod?
Missing items, repeats, unknown results, security
33
prerequisites to test reporting
- well defined measurement process in place - defined test measurements and other test status data to be collected - Test metrics to be used in recording test results
34
Test status data
- test context information - results from verification test - results from test cases (dynamic execution) - defects - efficiency
35
Productivity
Attribute of a process
36
Quality
Attribute of a product or service
37
Does a control chart show the tendency of measurement overtime?
yes
38
Test metric categories
- measures unique to test - metrics unique to test - complexity measurements - project metrics - size measurements - satisfaction metrics - Productivity metrics
39
pareto charts
A special type of bar chart to view the causes of a problem in order of severity: largest to smallest based on the 8020 premise -categorize items, identify the cause and characteristics, decide which problem to solve, understand the effectiveness
40
Check sheets
technique or tool to record the number of occurrences over a specified interval of time: A data sample to determine the frequency of an event
41
Run charts
- A graph of data in chronological order displaying shifts or trends in the central tendency coverage - Data represents measures, counts, or percentages of outputs from a process - Track changes and help understand the dynamics of a process
42
Control charts
A statistical technique to assess, monitor, and maintain a stable ability of a process -Objective is to monitor a continuous repeatable process in the process variation from specs
43
Environmental controls
means which management uses to manage the Organization - Organization policies - Organization structure - method of hiring, training, supervising and evaluating personnel - processes provided to perform day to day work
44
What are some advantages of using prod data?
- unusual data conditions - identification of code/values not indicated in the software specs - provide a model for use in creating test transactions, test scripts
45
Fitness for use
Meets the needs of the customer/user
46
user acceptance testing | UAT
Test environment looks like production
47
Statement of condition attributes
- activities involved - procedures used to perform work - outputs/deliverables - inputs - user/customer service - Deficiencies noted
48
Defect prevention process
1. identify critical risk -> 2. estimate expected impact -> 3. Minimize expected impact
49
attributes for defects
- statement of condition - criteria - effect - cause
50
corrective controls include:
-error detection and resubmission -error logs -audit trails -discrepancy reports -error statistics -back up in recovery Expensive
51
detective controls include:
-Control totals -control register -documentation and testing -output chicks moderate cost
52
preventive controls include:
-source data authorization -Data input -turn around documents -pre numbered forms input validation lowest cost/cheap
