The document outlines various software testing methodologies and their significance in ensuring robust software development. It discusses specific methods such as the Waterfall, V, Agile, Spiral, and RAD models, highlighting their advantages and disadvantages. The text emphasizes the importance of selecting the appropriate testing methodology based on project size, budget, and requirements.

1. Software Testing Methodologies to
Watch Out in 2020

2. The testing process is an essential part of any Software Testing
Company. A robust software product can deliver using standard
testing methodologies which help to predict the timeline of the
software system. The software can turn even more complicated
with many devices and platforms. It’s required to ensure that
they meet specific needs which installed and operated on the
user’s machine.

3. What are the Software Testing
Methodologies?
Software Testing Methodology defines strategy and testing types
with meeting client expectations. The methods include functional
and non-functional testing.
Few examples are unit testing, system testing, integration
testing, performance testing, etc. The testing methodology
defines the test objective, deliverable, and test strategy.
Methodologies considered a set of testing mechanisms used in
the software development lifecycle. Choose an appropriate
testing methodology that can view as a core of the testing
process. Let’s dive on to understand the testing techniques.

4. Testing Techniques

5. Three testing methodologies use testing.
● White Box Testing
● Black Box Testing
● Grey Box Testing
We’ll study each in brief for a better understanding of the
methodologies.

6. White Box Testing
It’s a technique that examines the program structure and builds
business logic. The code validates the program of an application,
so it’s called exact box testing or open box testing. The
technique includes- statement coverage, path coverage, and
branch coverage.
Black Box Testing
It is mainly used to test the functionalities of an application
based on the requirements needed. Same as white box testing,
it does not focus on the internal structure of t

7. Grey Box Testing
It’s a testing method used with less information about the
internal structure of the application. It performs like a black box,
but for some critical areas, it can use as white box testing. The
techniques include- waterfall model, v model, spiral model, agile
model, and RAD.
Take a closer look at each software development methodologies.

8. Waterfall Model
It’s a basic model of life cycle developed by Winston Royce in
1970. It represents multiple stages in a sequential manner which
flows progressively downward. The waterfall model used when
requirements are well-known, and technology is understood.
● Requirement Gathering
It’s a first step which allows to analyze and capture all
requirement. Make sure that the data is testable or not
before using it.
● System Design
Based on requirement gathered, one need to create and
design document. Later one can define hardware and
software requirements.

9. ● Implementation
Now, based on system design, create robust code for
documents as per the design and later integrate them.
● System Testing
With using the integrated components, the phase performs
to ensure that the system is working as per requirements.
Now track and report the testing progress.

10. ● System Deployment
If a system is stable with zero bugs, then make sure the
test criteria met, and it ensures environment setup.
● System Maintenance
Make sure that your application is working as per your
requirements and within a suitable environment. If in case,
there’s some defect then fix and deploy in the
environment.

11. Advantages of the Waterfall model
● It’s simple and easy to understandable
● It’s easy to handle at each phase with its deliverables
● It works well for small projects
● Overlapping stages can avoid

12. Disadvantages of waterfall model
● Increase the amount of uncertainty and risk
● Do not work well with complex projects
● Not suitable if you’re requirement keep on changing

13. V Model
We can call the V model as an extension of the waterfall model
as the process take place in a sequential style and known as the
verification and validation model. There exist a direct association
in every single phase of the development cycle. The model is
cost-effective and beneficial than the waterfall model as the
testing performed at every stage rather than at the end of the
cycle. It comes with three phases- verification phase, coding
phase, and validation phase.

14. Advantages of the V model
● It’s easy and simple to use
● Easy to manageable and suitable for small projects
● Overlapping is avoided and executed one at a time.
Disadvantages of the V model
Same as Waterfall model

15. Agile Model
It’s a model that shows an interactive and incremental approach.
It uses the approach that breaks the model into different
incremental units to provide iterations. The model allows each
iteration to involve steps like planning, requirement gathering,
design, coding, unit testing etc. The agile model gives continuous
iteration with the customer and takes feedback and requirements
based on regular intervals.

16. Advantages of Agile Method
● It uses a realistic approach to software development.
● Eliminates mismatch between requirements and test cases
● Suitable for long-term projects
● It requires a minimum amount of resources.
● Good for changing requirements
● Easy to manage and understandable

17. Disadvantages of Agile Method
● It’s doesn’t work well for complex projects.
● It can increase maintainability risk.
● It requires a massive amount of interaction.

18. Spiral Model
The model works with iterative development approach along with
the systematic approach and waterfall model. It works on an
incremental model that emphasis Risk analysis.
It comes with four stages – planning, risk analysis, engineering,
and evaluation phase.

19. Advantages of the Spiral model
● Helps in avoiding the high amount of risk
● Rapid development
● Changes in requirements accommodated with ease.

20. Disadvantages of Spiral model
● Not suits for small projects
● It’s costly compare to others.
● It requires a high amount of risk analysis.

21. RAD model
RAD (Rapid Application Development) is one type of incremental
model. It uses the approach where components developed in a
parallel manner. It uses rapid approach and give an immediate
product to the customer along with providing feedback. Few
phases of RAD are- Business modelling, process modelling,
testing turnover, and application generation.

22. Advantages of the RAD model
● The process can measure easily.
● It can increase reusability.
● It reduces development time.
● Get quick initial reviews.
● Enhances customer feedback

23. Disadvantages of RAD model
● Comes with high-cost estimation
● Need highly skilled resources
● With a modularized system, you can build using RAD.

24. How to choose the right software testing
services?
We’ll find a lot of methodologies to choose from in software
development. But when it comes to the software testing
Methodology part, we need to consider our requirements,
project size, budget, and scope. For smaller projects, it’s clear
that waterfall works well and benefits hugely. But if you have
large projects, then agile methodologies have substantial
benefits.

25. Wrap up
We would recommend using SDLC as soon as possible so as to
catch bugs at an early stage and incorporate testing feedback
into the design and build sets. Achieve better quality products
and shift your focus towards making quality assurance your
priority.
However, it’s your choice to choose single or multiple software
developments that lie at the core of the testing process. We can
call it a versatile activity that changes according to the business
requirements and software given timeline. If you’re looking for a
software testing company or want to hire QA analysts, then
connect with us and let’s discuss your requirements.
