Database Reference
In-Depth Information
Having the call graph and the component usages, which include column usages, we
can now perform inter-procedural data fl ow analysis. The result of this analysis is used later
for the call graph fi rewall regression testing technique.
Test Environment Setup
The tool also supports testing efforts. It creates a new version of the database applica-
tion that generates module and statement test traces when the test cases are executed. The
tool tackles the problem of documenting database applications test cases by adding to the
application input and output logging capabilities. The tool also uses its module and database
application display utilities to display statement and module test coverage.
Change Impact Analysis
The tool is capable of performing change impact analysis by handling two database
applications concurrently. It fi rst connects to the original database application and then it
connects to its modifi ed version. It performs analysis on both versions of the application.
