Testing Tools
Categories of testing tools
Black box testing, or functional testing Testing performed via GUI. The tool helps in
emulating end-user actions and generating data input
White box testing, or static analysis The tool scans the source code for logical
errors
Functional Testing Tools
Advanced Testing Tools Capabilities Produce test scripts via Wizard that allows to
Record business processes by emulating a user’s actions Insert checkpoints to compare actual and expected results Verify database value
Run test scripts Provide detailed reports of errors Provide the ability to customize test scripts or to program more
sophisticated test cases Ensure reusability of test scripts Can test both web applications and regular client/server apps
Functional Testing Techniques
The following technique is used to produce test scripts Create the GUI map Create test scripts with Test Script Language Create user-defined functions
The following technique is used to run test scripts The engine interprets the script, line by line Verify – compare expected and actual results Debug – record the test traces for analysis Update – runtime changes of the expected results or scripts
The following technique is used to analyze the results Review reports Analyze the results Report defects

Performance and Load Testing
Advanced Testing Tools capabilities: Create virtual users Generate load requests Capture runtime settings of the server environment Run load requests Monitoring of servers Produce the log Produce the reports Produce the diagrams to show time and resource
consuming diagnostic
Load vs. Functional Testing
Load testing tools emulate thousands of users when a functional testing is doing with a single user emulating
Load tests do not emulate user’s actions, they produce loading via API calls using the same protocols as the application does
Load tests differentiate application from its infrastructure and give specific results for each of them
Load testing tools
LoadRunner from HP NRG Performance Management Suite Other
Static analysis
Advanced testing tools capabilities: Visualize and re-engineer software architecture Reconstruct the workflow logic Discover inconsistency and errors in regards to the
code, such as Initial and late state Looping Race conditions Workflow control Incorrect object references Null pointers
Static analysis
Capable to discover security holes: Buffer overflow Memory leak Resource leak Unvalidated Input Broken Access Control Broken Authentication and Session Management Cross Site Scripting Buffer Overflow Injection Flaws Improper Error Handling Insecure Storage Application level Denial of Service
