Testing Couch 03 : Regression Testing

Theme: Regression Testing: Myths and Illusion’s

Date: 11/09/2014

In this session we discussed what we think regression testing is based around these questions:

  1. What is Regression Testing?
  2. Is a Regression Test the same every time?
  3. Do you need to do a Regression Test for every functional change?
  4. Should Regression Testing be automated?
  5. Are bugs found when doing Regression testing Regression defects?

I asked Q1 and Q2 of the following people and these were their responses:

Lead Developer:

  1. Checking something has regressed or not
  2. Do a smoke test every time, random selection it’s up to you


  1. Checking you haven’t screwed up things you haven’t changed or don’t think you’ve changed
  2. Checks based on what’s gone before and built up depending on new functionality

Director of Production:

  1. Looking to measure any detrimental changes to existing functionality that doesn’t fall in to the direct scope of what has been changed
  2. Therefore the Regression test is similar ever time, broadly similar and might have a body of tests that you’d approach most times

Development Manager:

  1. To test something which is related to the changes you’ve made
  2. That relationship should be driven by discussions and peoples experiences, check things that are related to what has changed


Fast forward the Audio to 3m 55s, unless you want to hear the setting up issues we had, most being caused by me :-D.


Attendees where: Michael CorumEmma KeavenyToby SinclairMichael BoltonSrinivas Kadiyala, Neil Taylor and me of course.

Although the discussion is mainly chatting there is a small transcript from the session as detailed below: With a Link to a pdf: *** Michael Bolton: Regression.pdf ***

I will be recording this session and publishing it, so if you object then I’d suggest two things, don’t talk and just listen or bail. :) Thanks.

This will officially last until 21:30 BST, anyone who wants to continue after that time can and I will pass control over to them.

As we are going to be talking on Skype we need to have some control.

Therefore this will be facilitated:

New Thread: ( envy ) without spaces skype_envy
Continue Thread: : ) without spaces :)
I must Talk Now: ( devil ) without spaces devil- You will be aloud to talk immediately, but this is a one shot, once used you may not be able to use it again, depending on if the reason is valid.

[9/11/2014 3:31:01 PM | Edited 3:31:11 PM] Srinivas Kadiyala: When we are talking on regression testing – do we need to perform the testing on every operating system / browser ?
[9/11/2014 3:31:57 PM] Srinivas Kadiyala: Clients / Managers would asks for regression testing on each browser.
[9/11/2014 3:32:03 PM] tobietrice86: :)
[9/11/2014 3:32:33 PM] Srinivas Kadiyala: Current updated browser – Whats the difference of doing the testing / regression testing?
[9/11/2014 3:32:40 PM] Michael Bolton: :)
[9/11/2014 3:33:26 PM] Michael Bolton: Beauty.
[9/11/2014 3:33:34 PM] Michael Bolton: I presume that’s Neil.

[9/11/2014 3:40:48 PM] tobietrice86: Toby
[9/11/2014 3:42:14 PM] Stephen Blower: cool thought so
[9/11/2014 3:43:52 PM] Stephen Blower: Backslidding term I like, as it seems to state what Regression actually is using a clearer term
[9/11/2014 3:52:19 PM | Edited 3:53:37 PM] Stephen Blower: -:)-
[9/11/2014 3:54:26 PM] tobietrice86: :)

[9/11/2014 4:17:15 PM] Srinivas Kadiyala: :)
[9/11/2014 4:18:19 PM] Stephen Blower: :)
[9/11/2014 4:27:04 PM] Srinivas Kadiyala: What if the bugs are not found by Tester A – during testing ,
But if the Tester B finds it in regression testing ?
(“Where there was no change in code/Build”)

Do programmers will/needs to accepts it?
[9/11/2014 4:27:37 PM] Srinivas Kadiyala: To fix it..
[9/11/2014 4:28:14 PM] Srinivas Kadiyala: Yes – Bolton
[9/11/2014 4:29:28 PM] Srinivas Kadiyala: Product owner can be manager / Client / BA ?
[9/11/2014 4:30:07 PM] Michael Bolton: The product owner, by definition, is the person who has responsibility for making decisions about the product and the project.
[9/11/2014 4:30:46 PM] Michael Bolton: The product owner MIGHT also be a manager, a client, the BA, an executive, the CEO, or any number of things.
[9/11/2014 4:31:13 PM] tobietrice86: Hey everyone – I need to head off in a mo. Feel free to carry on talking. Been a great chat!
[9/11/2014 4:31:18 PM] Michael Bolton: The product owner in this question is the one who has authority over the question, “Should this bug be fixed, or not fixed?”
[9/11/2014 4:31:28 PM] Michael Corum: Good to “meeet” you Toby
[9/11/2014 4:31:54 PM] emjaykay80: I am sure we will meet again Toby :D

Couldn’t check before the call ..
