Manual Testing for Beginners Advanced SDLC Models.
Advanced SDLC Models:
a) Fish Model: 
From the above fish model, multiple stages of development will come with multiple stages of testing:
- PIN – Project/Product Initiation Note, which will be prepared by PM(Project /Product Manager) to specify overall plan.
- BRS – Business requirement specifications, which will be prepared by Business Analyst (BA) , to specify customer requirements.
- Other BA can review that BRS for completeness and correctness.
- SRS – Software requirements specifications, which will be prepared by system Analyst(SA) to specify analyzed requirements.
BRS(BA ) —————–> SRS (SA)
(What to develop?) (How to develop?)
- Other SA can review that SRS for completeness and correctness.
- Technical Architect can prepare designs diagrammatically or pictorially.
- Other TA can review those designs for completeness and correctness.
- Reviews on BRS, SRS and design documents is called as Documents Testing (or) Verification.
- Programmers are responsible for coding to develop programs.
- Other programmers can test those programs by using white box testing techniques.
- Programmers can interconnect programs to build a Software.
- Other programmers can test interconnection of programs.
- Programmers can release software to testers.
- Testers can test complete software with respect to customer requirements and expectations.
- Customer site people (or) public opinion is mandatory before release software to customer (or) market.
- Programmers and testers can analyze that feedback to perform changes if required.
- Few programmers can concentrate on software release.
- Few Testers can validate software release process.
- CCB fresher’s (Change Control Board) are responsible to take change requests from customer site people and perform changes in software including testing, called as maintenance or support or service.
Note:
- The above fish model is costly and time taking. But it is follow-able in satellite software’s, aeronautical software’s, health equipment software’s, expert games etc.. because those software failure is more cost by comparing with project cost.

b) V-Model:
V -stands for verification and validation. From this model, software development will come with multiple stages of testing like in fish model. But in V – model, separate testers will come for software testing stage only.
- BA is responsible to prepare and review BRS.
- SA is responsible to prepare and review SRS.
- TA is responsible to prepare and review HLD and LLD.
- Programmers are responsible for coding, unit testing and Integration Testing.
- Testers are responsible for software testing.
- Programmers and testers can join together to collect feedback from customer site people for acceptance.
- Few programmers and testers can take care of release, and release testing.
- CCB fresher’s can take care of maintenance or service or support.
Note:
- The above V-Model can assure quality but some stages of testing by developers for cost deduction.

c) Agile Model:
Agile model is quality guaranteed model but it controls budget because this model depends on four points.
Agile manifesto:
- Individuals and interactions over process and tools.
- Working software over comprehensive documentation.
- Customer collaboration over contract negotiation.
- Responding to change over following a plan.
Note.
- Fish model is follow-able to develop satellite software satellite software’s, aeronautical software’s, health equipment software’s and expert games like Artificial Intelligence software’s(AI).
- V-model is follow-able to develop banking, insurance, e-commerce, health care, financial services, logistic etc.. like commercial software’s.
- Agile Model is suitable to develop both commercial and artificial intelligence software’s, but customers collaboration is mandatory.
