Technical Test Analyst Tasks and Skills
Similarities with TA:
 The Technical Test Analysts (TTA) supports an effective test process
 Focus on the analysis and design steps
 Often there is no fixed TTA role
Different focus of TTA:
 For the TTA the focus is on technical aspects
 Risks associated with technical quality attributes
 Working closer to the architecture and code
 Becoming more relevant !
 Required skills set expanding rapidly

Analytical Techniques
 Static analysis
 Control flow analysis (e.g., dead code, endless loops)
 Data flow analysis (e.g., incorrect use of data in code)
 Call graphs (e.g., to help identify bottle-necks and determine integration
sequences)
 Dynamic analysis
 Memory use (e.g., identification of leaks and incorrect usage of pointers)
 Tool support
Functional
Suitability
Usability
Performance

Security Testing
 Typical categories of security vulnerability (e.g., DOS, input buffer overrun)
 How to approach security testing (broadly)
 Planning aspects (e.g., identification of security risks and vulnerabilities)
 Test design aspects (e.g., design of security attacks)
Performance Testing
 Typical types of performance test (e.g., load, stress, volume)
 How to approach peformance testing (broadly)
 Planning aspects (e.g., identification of performance risks)
 Test design aspects:
 Identification of usage profiles for different types of user
 Construction of load profiles to examine system performance
under different conditions:
 Normal load
 Maximum load
 Stress loads
 Data loads
Reliability
Maintainability
Portability
Compatibility
Other Quality Characteristics
 Recognizing the need to evaluate
the different attributes and their
sub-attributes
 How to approach testing (broadly)
