D, E, F’s of Software Testing


D for Data
Data Testing - Do extensive testing of the input and output data and provide coverage in terms of the below. 

For its legal usage and infringement of the right to data privacy. What data can be used and when and who can use it and why?
Test the data - how is data collected, stored/saved, transmitted, used and disposed of.
Test the data - for correctness and reliability. Not everything on the Internet is from a trusted source.
Test the input data - for idiosyncratic patterns.
Test the output data - if it's spewing out relevant output for the input fed.
Test the data - input fields for the invisible forces attacking them.
Test the data - for who prepared it, who is the end user, are they the authorized end user, where did we get the data from, where are we storing it, how are we storing it, how better can we store  it, how securely can we store it, how else can we use it, how legitimate the data in transit is, how do we distribute it across systems, third party and otherwise, are the users aware of how their personal/valuable information is stored and used, who/which tool generated the input data, is this tool licensed, how is the data generated, who are the makers of this tool, who else can access the data and how is the data disposed of.
Test the data - for its quality.

The question for us to think about here is:
Why are we collecting this data from a user?
Answering this question can help in solution-ing the software for apt usage and can help reduce the cost incurred in designing, implementing, testing and when the solution is released to the users.

E for Evidence
Evidence collection of the testing performed is of utmost importance to testing. It is also significant to understand the value-addition of testing evidence produced and provided to the client.

Testers need to be trained to use tools to capture and produce evidence. From the project initiation phase to completion and beyond, evidence of the testing done, coverage provided, scope altered, tools used, checklists filled are filed by testers for the consumption of an end-user. The test lead needs to ensure that the test evidence is easily accessible to the consumer (for the client) and in time.

Be punctilious of the testing approaches you learn and use, as it creates value. Including the context-driven test approach which sets up the tester to form and base the testing by cautiously understanding the context. Failing to state the context prior to performing testing and during execution, can set the product up to have lousy quality.

With evidence collection, the testers learn the fine distinction between testing and providing proof. Without which, testing is deemed valueless.

The question for us to think about here is: 
What steps you take or have taken to gather evidence?

F for Fact
Lest we forget the value addition of the reviews, root cause analysis of the bugs which reveal that lack of fact-checking can be fateful to any project.

Testers as fact checkers can ultimately lead them to be and become better quality contributors.

Fact checking as part of testing can trigger a tester to be hawk-eyed during the whole process and make one quality conscious. 

The statement of work
Collated product and testing requirements
Use cases referred and used
User stories created and suspended
Agreed user acceptance criteria
Test ideas, charters designed for execution with valid and invalid inputs
Product understanding and bug review
Test reports and graphs generated
Risks encountered and mitigation planned
Experience and closure reports

The side effect of doing this helps a tester to better time track the testing activities one is involved with. And raise relevant questions related to estimation which is a faux-pas when planning for testing is considered.

All of the testing related activities needs to be fact checked for. Testers, practice checking for facts before filing a bug or sending out a test report. Tester vocabulary used when testing and not testing plays a prime role in doing so.

The question for you here is:
Dear testers, have you fact checked today?
