What is QA / QC

QA – are we making the product right.

QA is related with process

It is pro-active approach

It is monitoring of the SDLC using different tools like reviews, Audits etc.

QC – have we made the product right.

QC is testing the product against the requirement/ specs

It is reactive approach


QA or QC

In general we do QC however there are some elements of QA that we employ


What is Bug Life Cycle


Cost of Bug

What is a Bug (or Defect or Error)?

Any undesired behavior is a bug

Any deviation from specs / requirement is a bug

Any behavior which is “not written / mentioned” in specs is a bug

Cost of bug is difficult to calculate:

Cost of having QA team(s)

Cost of having Application engineers

Cost of losing face in front of end user


“Throw it over the wall”

What is a throw it over the wall ?

• "Throw it over the wall" is a business slang for completing your part of a project and then passing it off to the next group without testing or without sufficient testing.


Different Types of Testing

Unit Testing

Integration Testing

System or Functional Testing

Regression Testing

Performance Testing

Installation

And the list goes on...


Software Test Plan Example

Let us have a look at the 'high level' – generic contents of the “Baton Content Corrector” test plan.


Regression – What is Regression testing

In short regression testing is a type of testing to make sure that the changes or fixes done in the software does not break same part or any other part of the software.

Regression can be employed at various levels / components of a software.

Regression implementation can be manual or automated.

It is highly desirable to have regression automated.

Different tool(s) / language can be used to implement regression


Regression - Example

Regression is implemented at various components of DMG products

Different Regression implementation(s) in Baton:

Checker Application or 'back - end' regression implemented using 'python' language

GUI or 'front – end' regression implemented using 'Selenium' tool

Different tools / languages can be used to implement a single regression flow.

Baton's 'back - end' regression implemented using 'python' and PHP language.
