Exactly how are front-end and back-end testing different? Presented By AfourTechnologies USA
Quality and accuracy have become crucial in the race to
release high-end software solutions since they will help your product stand out
from the crowd. Software must adhere to strict quality requirements. Software
testing now has a responsibility to produce the finest software possible.
To deliver a memorable product, an end to end testing
strategy covering both the front-end testing and back-end testing is necessary.
But what is front-end testing and back-end testing? And how exactly are
front-end and back-end testing different?
Consideration of current programmes as having a 3-tier
design is one method of deconstructing their architecture. This is made up of
three layers: the database layer, the business logic layer, and the
presentation layer.
Modern-day applications typically consist of a 3-tier
architecture, with the presentation layer, business logic layer, and database
layer. To ensure that the presentation layer provides a seamless user
experience, businesses often rely on Front End Development Services
and Frontend Development Services
providers who specialize in developing responsive and visually appealing user
interfaces. The front-end testing is largely performed on the presentation
layer. In a typical web application, front-end testing would involve testing
the functionality, usability, and performance using a variety of testing
strategies and validation checks. In a client-server architecture, the
front-end testing is done on the client side of the application.
With this three-tier architecture, the database and
business layer are where the back-end testing is carried out. Or in a
client-server architecture on the server side of the application. The business
layer includes the application's business logic, therefore back-end testing
entails looking for major flaws in the program's logic, such as the possibility
of damaged data, data loss, or erroneous business rule operation.
Due to the fact that front-end testing involves
examining the GUI (Graphical User Interface), the tester not only needs to be
well-versed in business requirements but also in how users interact with
systems. This is important in order to spot problems with the application's
usability. For instance, the tester may need to look for validations when
testing a ticket booking application. The application must not permit the entry
of names using numbers.
The ability to load test an application under the
pressure of users requires knowledge of automation testing approaches.
Depending on the needs of the business, the tester for a web application must
determine the load the programme can withstand when used by people located
around the nation or the world.
In front-end testing, the tester will also need to check
the look and appearance of the application and how these come together.
Deep understanding of the underlying theories,
languages, and technologies may be necessary for backend testing. Backend
testing, in contrast to front-end testing, connects directly to the backend or
the database for testing instead of relying on the graphical user interface.
Data can be passed through a browser during backend testing to verify the
expected outcome. Verifying how the application functions will be a crucial
role in backend testing, and this may require knowledge of API (Application
Programming Interface) testing approaches.
Front-end testing demands a user-focused testing
strategy. That apart:
●
In an age of Cloud products and
services, front-end testing requires a sound testing plan to test Integrations
with complex SaaS services.
●
The rising usage of web
applications by diverse groups of customers calls for a stable user testing
method.
● With applications extending to more
and more devices, testing functionality and accessibility across a variety of
devices becomes imperative.
Testing strategies that come under the scope of
front-end testing:
●
Unit testing and Integration
testing
●
Accessibility testing
●
User testing
●
Visual regression testing
●
Performance/Stress testing
●
Automated browser testing
Back-end testing is mainly concerned with the functional
features of an application's data flow and other backend elements. Backend
testing involves a variety of testing tests, including data validity and data
integrity checks, performance testing, testing of stored procedures and
triggers, testing of sequences, and testing of the database's table, key, and
index structures as well as its stored procedures and triggers. Server
verifications and tests for data duplication may also be part of backend
testing.
Testing strategies that come under backend testing are:
●
Structural Testing
●
Stress Testing
●
Component Testing
●
Boundary Testing
A comprehensive front-end testing strategy delivers the
following benefits:
●
A well tested front-end creates a
user-friendly application.
●
It creates a better clarity of the
scope of the application from the user’s perspective.
●
Since the focus of front-end
testing is on usability issues, it helps development teams understanding the
target audience.
Backend testing has the following benefits:
●
It is possible to detect bugs in
the early phase of application development itself.
●
Backend testing allows a more
detailed checking of how the application works.
●
It ensures comprehensive coverage
of the functionality of the application.

Despite the differences, both front-end testing and
back-end testing must come together to deliver a high-quality product.
