Test Data Preparation
A test data is a data that exits in an existing database before a test is executed. A type of test tool that enables data to be selected from existing database.
It is useful if a large volume of data is needed for testing.
It is useful for performance and reliability testing.
Characteristics
Extract selected data records from files or database.
Enable records to be sorted in order.
Generates new records
Tool Support for Test Execution & Logging
Test Executions and Logging Tools
Test Comparator
Coverage Measurement Tool
10 Tool Support for Test Execution & Logging
Test Comparator OR Test Comparison Tool
Test Comparison
The process of identifying differences between the actual results
produced by the component or system under test and expected
results for a test.
Test comparison can be performed during test execution (dynamic
comparison) or after test execution.
Test Comparator
11 Tool Support for Test Execution & Logging
Two ways of comparing actual results with expected results
1.Dynamic Comparison (comparison is done while the test is executing)
2.Post-Execution (comparison is done after the test has finished executing and software under test is no longer running.
Dynamic comparison is useful for comparing the wording of an error message that pops up on a screen with the correct wording.
It is useful when an actual result does not match the expected result in the middle of a test.
12 Tool Support for Test Execution & Logging
Characteristics
1.Dynamic comparison of temporary events that occur during
test execution.
13 Tool Support for Test Execution & Logging
Coverage Measurement Tools
A tool that measures statements, decisions and branches whether these have been exercised by a test suit.
Characteristics
1.Identifying coverage items
2.Reporting coverage items that have not yet been exercised by a test suit. 3.Calculate the % of coverage items that were exercised by a test suit.
14 Tool Support for Test Execution & Logging
Security Tools
Security
Attributes of a software that prevent unauthorized access.
Security Tool
A tool that provides support for security.
Security Testing
Testing to determine the security of the software product.
15 Tool Support for Test Execution & Logging
Characteristics
1.Identifying viruses
16 Tool Support for Performance & Monitoring

17 Tool Support for Performance & Monitoring
Performance, Load, and Stress Testing Tools
Performance Testing Tool
It is concerned with testing at system level to see whether or not the system will stand up to a high volume of usage.
Load Testing checks that the system can cope with its expected number of transactions, number of parallel users. It is used to determine what load can be handled by the system.
Volume Testing checks that the system can cope with a large number of data e.g. many fields in a record, many records in a file etc.
18 Tool Support for Performance & Monitoring
Characteristics
1.Generating a load on the system to be tested
2.Measuring the time of specific transactions as the load on the
system varies.
3.Measuring average response time
19 Tool Support for Performance & Monitoring
Monitoring Tools
It is used to continuously keep track of the status of the system
in use and to improve services.
Characteristics
1.Identifying problems and sending an alert message to the
administrator.
20 Tool Support for Performance & Monitoring
Debugging Tool
Debugging
The process of finding, analyzing and removing defects.
1.Developers use debugging tools when identifying and fixing
defects.
21 Tool Support for Performance & Monitoring
Benefits of Tools
1.Reduction of repetitive work
2.Greater consistency and repeatability
3.Objective assessment
4.Accuracy
