What Is Software Testing?
Software
testing is an activity
that ensures the identifications of bugs, errors, and defects in software system.
It involves execution of a software component or system component to evaluate
one or more properties of interest.
Testing is the subset of quality control.
Software Testing involves following -
1. Testing
meets the requirements that inspect its design and development phage
2. Responds
correctly to all kinds of inputs
3. Execute
its functions within an acceptable time
4. And
so on
Types of Software Testing -
1. Functional Testing
- Unit Testing, Integration Testing, Smoke, and UAT
2. Non-Functional Testing
- Performance, Endurance, Load, Volume, Scalability, and Usability
3. Maintenance
- Regression and Maintenance
Why Is Software Testing Important?
Software Testing is very important because the software’s
bugs, errors, and defects could be dangerous and it is very harmful for our
products and applications.
So each and every software products or web applications
should be tested at least black-box and white-box testing.
What Is Quality Assurance?
Quality Assurance is known as QA aim is to
prevent the defects and managing the quality of products.
Quality assurance consists of that part of
quality management focused on providing confidence that quality requirements
will be fulfilled.
The quality assurance involves in process oriented
activities that ensures the prevention of bugs, errors, and defects in the software
products and apps.
So the defects do not happen when your software
products or apps are being deployed on the cloud server.
What Is Quality Control?
Quality Control is known as QC and focuses on
identifying and improves the defects, bugs, and errors of products or apps.
The quality control involves in product oriented
activities that executes the applications code to identify the bugs, errors and
defects in the software apps.
Quality Control is that part of quality
management focused on fulfilling quality requirements.
What Are the Differences between Quality Assurance vs. Quality
Control?
1. QA
is a verification process.
2. QA
is the process of managing for quality.
3. QA
is the process to create the deliverables.
4. QA
is responsible for full software development life cycle.
5. QA
is process oriented
And
1. QC
is a Validation process.
2. QC
is used to verify the quality of the output.
3. QC
is the process to verify that deliverables.
4. QC
is responsible for software testing life cycle.
5. QC
is product oriented
QA performed before QC.
What Is Validation?
Validation is the process of evaluate the final
product to check whether the software meets the business needs.
Validation represents dynamic testing techniques.
What Is Verification?
Verification is a process of evaluating the
intermediary work products of a software development lifecycle to check if we
are in the right track of creating the final product.
What Is the Differences between Verification and Validation in Software
Testing?
Verifications -
1. Execution
of code is not comes under verification.
2. Verification
uses methods like reviews, walkthroughs, inspections, and desk- checking.
3. Verification
finds bugs early in the development cycle.
4. Verification
comes before validations.
There are four types of verification -
Component
Testing - This testing verify a software element (unit).
Integration
Testing - This testing verify if the units work
together.
System
Testing - This testing verifies and meets the system
requirements.
Acceptance
Testing - This testing verify the system satisfies acceptance
criteria.
Validation -
1. Execution
of code is comes under the validation.
2. Validation
uses methods like Black Box Testing, White Box Testing and non-functional
testing.
3. Validation
can find bugs, errors or defects that the verification process cannot catch.
4. Validation
comes after verifications.
