Software Testing - Verification VS Validation

Software Testing - Verification VS Validation

Friends Verification and validation are independent procedures that are used together for checking that a product, service, or system meets its requirements and specifications. These are critical components of a quality management system.  
In this video, let's try to understand the concept of Verification and Validation in an easy-to-understand manner.

This guy has solved my 10 years old headache on V&V🤣🤣... Thank you!!

This is an EXCELLENT video! Thank you for sharing this information!

Unit testing and integration testing is not for validation testing it's for verification

Are most big companies using the SCRUM / Kanban methodology (or framework) to satisfy the AGILE/Waterfall/V-Model philosophy (SDLC) ?

I'd like to move away from a rapid-prototype environment to something more formal in order to develop high quality/safe products containing embedded software.. for ANY industry.. Aerospace (like Lockhead's SEAL Level X, Boeing, DDPMAS, DAL A to E etc), Medical or Nuclear industries.. even Automtovie. I'd love to see a trivial project example that shows all the steps and outputs.

For example, assuming I document the process on how the code is generated, what constitutes proof that it's safe?
Static Analysis?
Code Coverage - Statement (Level C), Decision (Level B), MCDC (Level A)?
Who defines the unit tests?

I imagine there are differences between the industries..
FAA : DO-178X, DO 331, ARP4754A , ED-12C
FDA : 13485, ISO14971, IEC 62304, SaMD and
DOE Nuclear : 414.1x,
(Automotive : 26262)

but what are the typical tools/software needed, and the typical document/artifacts in the various stages of the software life cycle?

I saw a good video by CEMILAC Education Program "Airborne Software Development & Certification Process" and it's a bit overwhelming:
Requirement Management - (IBM Ration) DOORS, JAMA, Xebrio, rmtoo florath, doorstop-dev / doorstop, reqview
Static Structural Source Code Analysis - Parasoft, PolySpace, CodeSonar, horusec, SonarCloud, veracode PREFast, TBrun, LDRA
Dynamic Analysis / Modified Condition/Decision Coverage (MC/DC) - VectorCAST, RapiTest
Traceability Tools: Reqtify, Polarion, McCabe
Configuration Management / Storage and Version Control System - Git, SourceSafe, Mercurial, MS TFS, ClearCase
QA / ALM- Helix ALM for Managing Artifacts, Establishing Traceability, Documenting / Enforcing Processes, etc
(I)V&V / Unit Test Automation - VectorCAST, LDRA Testbed, Mathworks Simulink DO Qualification Kit
Continuous Integration / CD - Continuous Delivery/Deployment - Jenkins, Bamboo, or GitLab CI/CD

And what is the general attitude towards open source software (ex. FreeRTOS) and code-generation tools (ex. ST's Cube MX)?

Also, how do CPLD and FPGAs fit in to the embedded software picture.. since not exactly software nor hardware, since they are programmable devices written in an programming language like VHDL, (system) verilog, Amaranth HDL ? How would DO-254 apply to HDLs?

Watch at x1.5 speed, you are welcome.

This is incorrect. Verification is not static testing only. I agree that the foundation istqb sylabus lets place of interpretation. But to understand better verification vs validation start first with Test manager sylabus.

A bit enthusiastic while talking and a bit fast while talking 😅😅

How we solve software debugging code ? What is steps for to develop driver for new function ?

[vinajain]

If ADC driver is not working how we will debugg it ?
