Non linear paths from Application Code

October 4, 2007
The applications become complex as their code base increases. This has challenges for the testers to determine the nonlinear paths in the application.

Most of the Static Analysis tools over the application code helps us to  identify the  cyclomatic complexity (nonlinear paths) at a method level. These might be helpful to validate those methods and to achieve good code coverage over the same.

But the Code coverage at a Unit Level may not be a big help since most of the end user scenarios won’t run after unit level paths. These paths is an integration of the above unit level paths.

Since the Testers focus on simulating the end user scenarios, it will be good to identify all the possible nonlinear paths around the application code base and capture the code coverage based on these paths.

You might want to go through some discussion around this on Linkedin Answers

Happy Testing…

Ability to identify the hot spots of release from Bug Database

September 24, 2007

Bug Database for the products might have thousands of issues over a period of time against various builds and releases. Though these issues fixed over a period of time, it might be hard to derive meaningful metrics over the release.

We need to support these releases over the production systems & it might be helpful to capture the hotspots / risk elements with the release. Most of the issues here to deal with the respective features, compatibility with other features / technologies & performance related issues.

The usual metrics of number of issues against a module and their severity levels may not be of help always.

How easy is it to derive the following from the Bug Database for a given release

  1. Identify the issues have originated from Requirements, Design & Implementation
  2. Identify the issues over their category (Functional, Performance, Security, Compatibility, Usability etc)
  3. Identify the issues along with their origin & category over the features rather than the modules / components

Open Source Tools to test your Java Code

April 16, 2007

Open Source tools are being used aggressively and there are many tools that can help Java Applications to validate their code.

The following issues can be uncovered

  • Unhandled exceptions
  • Infinite Loops
  • Dead code
  • Validations against Java coding guidelines from Sun

The following Metrics can be captured

  • Source Code Metrics
  • Coverage Metrics
  • Dependencies with the Design

Couple of resources listed below helps in implementing the same.
