| My quest towards Code Quality Metrics |
| 2007-10-23 14:10:54 |
The term quality might mean different things to different people based on their context of operation and it’s tough to have universal definition for the same.My experiments with software development started over a decade ago & exploring the ways the helps to build & deliver good quality code.The quest towards Code Quality Metrics started with [...]...

| CRAP4J for Java Code Quality |
| 2007-10-22 03:31:57 |
I have been talking about Code Quality through Static Analysis for a while here, here & here. The quality for any application development must begin from it’s gross roots and the Application Code is one of it’s starting point to begin with.Static Analysis techniques help us to identify some metrics over the application code base
Cyclomatic [...]...

| What Jar - Solution to NoClassDefFoundError |
| 2007-10-22 00:48:12 |
As a Tester & Developer, it’s pretty common to see NoClassDefFoundError. It’s not that easy always to figureout the required jars for the application.
Whatjar comes with a lot of search capabilities to identify and download the required jars.
Whatjar is a high-performance, search engine written using Java and MySQL to index and search Java JAR contents. [...]...

| Non linear paths from Application Code |
| 2007-10-04 04:49:58 |
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 [...]...

The popular myths around Blackbox & Whitebox Testing are by it’s name. It’s black since we can’t see it (don’t have access to the code) & it’s white since you have access to all the code. But then, With in the code there are many black boxes inside and it’s tough to have access to [...]...

| Use Cyclomatic Complexity to determine the Risk and Test Scenarios |
| 2007-07-18 21:33:30 |
Cyclomatic Complexity (CC) is a software metric (mostly code based metric) used to the number of independent path executions in the application. Introduced by Thomas McCabe in 1976, it measures the number of linearly-independent paths through a program module.
It helps the developers to determine the independent path executions and base line unit tests that they [...]...

This is my first post in the Bug Life Cycle Series. I need to talk about this because when it comes to the role of testing, it’s not clear. The Role of Software Testing is often mis-understood across the different stake holders of the application development & this list includes testers too.

| Lessons to be Learned from the Bugs |
| 2007-04-30 15:32:48 |
In this post, I will be looking at Bugs with an insight that helps testers to learn some new lessons on why the same might have occured. It’s quite common that the testers are blammed for all the missed out bugs in the system as if they are super natural powers to over see all the issues that are there in the system.
Bugs are there every where. Not just software applications, look at any system for that matter & there are issues wrt End User needs and the same might need to evovle over a period of time with the changing needs / requirements from time to time.
What is a Bug ?
It’s tough to arrive at a generic defintion for the bug & people might have heated discussions on what is a bug & what is not. Mostly it’s based on the context in which people are working. We do come across many bugs in our daily life while working with the tools that are needed for the day to day operations.
So in my context, Bug is something...

| Open Source Test Management Tools |
| 2007-04-22 20:38:24 |
In this post, i will share my views & findings with Source">Open Source Test Management Tools. Usage of tools in the Test Management is becoming the basic need & It will be tough to manage the activities associated there with out any support from the tools.
The commercial tools in this segment are costly and may not fit into upcoming organizations budget. So i have been looking at Open Source Test Management tools. In the last week, I have evaluated some open source test management tools.
The following are my requirements for Test Management Tool
Capture the Requirements
Design Test Cases
Map Test Cases with Requirements
Link Bug reports with Test Case ID after the test execution
Test Execution Reports
Version Management for the Test Cases
Search Feature
The following tools are evaluated after the initial screening.
TestLink
RTH
The above tools work with Apache, MySQL & PHP. Both the tools looks promising and the Test Link has some additio...

| Taking on “Testing Triangles - A classic excercise” |
| 2007-03-24 00:16:46 |
Solving puzzles, sudokus & the analytical problems is one of my hobby. This set of puzzles always helps me with some brain food which mandatory to stay tuned in the current trends.
I was going through this Testing Triangles post from Elisabeth Hendrickson from Quality Tree Software. The triangle program is very much popular to the world of testers and many of the books and blogs have already covered the same.
Elisabeth posted this as a testing puzzle and asks the people to uncover the bugs in her program. The beauty of this Triangle program is that whole code is available for the tester since it’s written using JavaScript.
I couldn’t stop my self exploring the program and discovering some issues with Testing Triangles and logging them into comments sections while in hurry too.
I thought for a while on this program in the evening and felt that there are many similarities for this even though it’s very very small when compared to the real world applications w...

| Role of a Tester - An interesting discussion with an upcoming tester. |
| 2007-03-22 21:50:10 |
Today i had an interesting discussion on the role of the testing with an upcoming tester Debasis from Chennai, in India.
Debasis: Hi venkat
Venkat: what’s up debasis
Venkat: going great. Happy Testing and more posts on my blog these days.
Venkat: That’s interesting. let me ask you some stuff on Testing
Venkat: what’s the role of testing in SDLC
Debasis:The same as of parents in the upbringing of a child
Venkat: oh. That’s interesting. But don’t you see it’s the role of the management more
Debasis: Okay b4 I cud answer, i want ur definition of SDLC
Venkat: The process used to develop software the phases involved init
Debasis: But to me the processes can be of many types and of different approaches. Assuming that I am following a generalised SDLC approach…
Venkat: go ahead.
Debasis: The role of testing is to ensure that the intended user gets a good quality product after the release
Venkat: hum. good quality product. great go on.

| JavaNCSS - A source metric suite for Java |
| 2007-03-15 16:39:53 |
I have been looking after LOC counters to capture some metrics of the source code and found that JavaNCSS is a good match.
What is JavaNCSS ?
JavaNCSS is a command line utility which measures some standard source code metrics for the Java programming language. The metrics are collected globally, for each class and/or for each function.
What are the advantages ?
The following are some of the advantages that i have seen
Support for Ant Tasks, so easy to integrate with build process
Reports can be in Text, XML, HTML etc
Support for Stylsheets and easy to get nice HTML reports
Metrics at each level Package / Class / Method
Cyclomatic Complexity Number
List the number of packages / classes / functions / LOC counter at each level

| Tester is not a Quality Police |

The perception from most of the management is that the Testers are the quality police for the products / projects that they develop. This is true for most of the companies where there is no Quality Assurance group.
What do i mean by a Quality Police ?
Is the requirements freeze done for the product
