My Approach to Regression Testing - R3C'sFI

By -
I have done a fair amount of regression testing. And Sometimes I used to think "Oh..Again!"

 But I gained knowledge based on the experience - "When to Perform" and "What to Perform" Regression Testing.
When do we do Regression Testing?


  1. Defect Fixes
  2. Performance or Security Issue Fixes on Code
  3. New Features Added 
  4. Optimization of Existing Features 
  5. Any changes in Integration Systems (Example: Payment Gateway System Software Upgraded from Version 1.0 to 2.0)
  6. Server Related Updates (Example: Movement of Application from Hosted Server Systems to Google Cloud)
  7. Software Version Updates (Example: Java Updates or JS Updates)

What to Perform as Regression Testing?
  1. Testing the Recent Code Changes  -- R
  2. Testing the Core functionalities of the Application  -- C
  3. Testing the Customer Specific Features (Example: Which are developed specifically for a customer on top of core functionalities)  -- C
  4. Testing the Configuration Related Features (Example: Verifying the Application is enabled with Email Configurations)  -- C
  5. Testing the frequent issues which were encountered after every deployment or release  --- F
  6. Testing the Integration Features (Example: API Integration with ERP System - Order Placement, Payment Gateway Integration - Credit Card Order Placement)  --- I


I devised a mnemonic: RCCCFI  (R-3C's-FI)

After running JMeter.bat on Command Line, Problem java.util.prefs.WindowsPreferences <init> WARNING: Could not open/create prefs root node Software\JavaSoft\Prefs at root 0x80000002.

Windows 7 64-bit The work around is to Open JMeter.bat file as the administrator and so it creates the key HKEY_LOCAL_MACHINE\Software\JavaSoft\Prefs.

Understanding about Contract Testing

Yesterday Morning (9th May 2020), I had good discussion with  Sundaresan  Krishnaswami on " Contract Testing ". I thank  Sundaresan   for his time and sharing his knowledge. It started with an example: The Owner provides the house or Place of Residence to the Tenants. "Rent Agreement" is provided for the house and It contains agreement to use the house. The house comes with like kitchen, living room, bed room, fans, geysers etc.. It also contains who resides and what is the contractual period, obligation (money) etc.. Here, Owner is the Server and Tenant is Client.                                         Client-Server Architecture. Illustrating the same in the E-Commerce Context: In Some Development Companies, There can be two teams developing the Payments and Orders APIs. In B2B or B2C Ecommerce applications, we place an order using web browser through payment methods...
