Code Duplication Analysis

...

Jtest

can Jtestcan check for duplicate code to help you improve application design and decrease maintenance costs. During code duplication analysis, the code is parsed into smaller language elements (tokens). The tokens are analyzed according to a set of rules that specify what should be considered duplicate code. There are two types of rules for analyzing tokens:

Metrics Analysis

...

Jtest

can Jtestcan compute several code metrics, such as code complexity, coupling between objects, or lack of cohesion, which can help you understand potential weak points in the code. Run the Metrics test configuration during analysis to execute metrics analysis rules: 

...

• By using the test configuration interface in DTP (see "Report Center> Test Configurations> Editing Test Configurations> Metrics Tab" in the Development Testing Platform DTP user manual for details).
• By editing the Metrics test configuration using the interface in an IDE (see Creating Custom Test Configurations).
• By manually editing the test configuration file:
  

  1. Duplicate the built-in Metrics test configuration ([INSTALL_DIR]/configs/builtin) to the user configurations directory ([INSTALL_DIR]/configs/user).

  2. Open the duplicate configuration in an editor and set the [METRIC.ID].ThresholdEnabled property to true.

  3. Configure the lower and upper boundaries in the [METRIC.ID].Threshold property according to the following format: [METRIC.ID].Threshold=l [lower boundary value] g [upper boundary value]

  4. Save the test configuration and run the analysis using the custom metrics test configuration.
