Top 7 Reasons Why Software Testing is Crucial in SDLC
Software Testing is an important thing in Software Development Life Cycle (SDLC) because errors can
occur anywhere in the application and some of them remain undiscovered until deployment. The final
product with bugs brings many difficulties such as redevelopment, wastage of cost and time, poor
functionality, and many more. Software testing proves the quality of the product that helps to gain
more customer satisfaction by meeting their requirements in an application or a product. Therewith,
we have presented here the top 7 reasons for the implementation of software testing in SDLC for the
betterment of an organization's rapid growth.
To Detect the Errors of an application
Software Testing consists of four main levels in functional testing such as Unit Testing, Integration
Testing, System Testing, and Acceptance Testing. These levels of testing used to detect the errors that
may occur in any block of codes.Generally, errors areclassified as follows:
Functionality Errors: These are the errors that the behavior of the application is not working as
expected or in a wrong way which confuses the users.
Communication Errors: This type of error occurs when any part of the module is not redirected to the
next module as expected by showingunnecessary commands or any.
Missing Command Errors: It occurs when the expected command such as cancel, exit or back is not
presented in the placeitrequires.
Syntactic Errors: These errors are the grammatical mistakes or the misspelled words presented in the
commands or buttons.
Exception Handling Errors: If errors occur during the user interaction with the application required to
be handled by the exception handling in a clear and meaningful way. If not, it shows Error on
Exception handlingerrors.
Calculation Errors: Calculation errors will occur in the situation such as bad logic, incorrect formula,
data type mismatch, codingerrors,and function call issues,and so on.
Control Flow Errors: Control Flow errors will be raised when the application missed describing what
to do next and in what condition to be executed.
These errors should be detected and handled by the software testers to avoid the complexity of the
deployment process.
To avoid cost wastage

The poor test data management has to face unwanted difficulties after a deployment that is needed
to spend more cost on the redevelopment process. There are many ways to reduce the software
testing cost and some of them are as follows:
 Execute the test process early along with the development process
 Prioritizethe performance and security issues
 Minimizethe manual testing from day one
 Avoid hand-codingof the User Interface tests
 Utilizethe modern testing and automation tools
 Standardizethe entry and exit criteria
Software testing helps to reduce the wastage by implementing it with the appropriate planning of
automation and frequent testing process.
To Verify the Software Portability
Software Testing is important to check the adaptability of the application of the software that ensures
the working progression of all the operating systems and browsers well and clear. It should give users
a smooth experience that will not affect the application efficiency in case of changing the device.
Software testing avoids the errors caused during the change of devices with the following testing
attributes:
Installability to check whether the application can be installed in any targeted device that meets the
characteristics of operating system requirements, browser requirements, memory or RAM
requirements, simplified Installation and uninstallation procedure, interruption exceptions, and
prerequisites details,and so on.
Adaptability Testing of the application is to validate the system whether it can adaptable to all target
devices with the meeting of characteristics such as hardware, software dependency, standardized
language,system communication,dependency encapsulation,and dependency representation, etc.
Replaceability is to check the ability to replace one software component with the other that produces
the same results as the previous one.
Compatibility or Coexistence is to check the ability of the application can behave with two or more
components with the same frequency without affecting the adverse behavior of each other.
Interoperability testing helps to determine the errors that occur when the two or more components
communicate with each other.

Localization is done to ensure the developed software can be understood by the users of the local
language.This testing is done mainly for internationalized applications.
To avoid the risk of losing the crucial information
Software Testing is essential to avoid the loss of important information during the application running.
It will bedone in the followingthree strategies:
Creating the policies around the real data: Organizations often develop or revisit the policies and this
to be tested before implementing. The application should protect the existing data in case of adding
the new one.
Ensuring the access rights for preventing the data: The application should be developed with high
authorization or login facilities to protect the data from unauthorized access.
Utilization of proper techniques to protect data: Testing to be done to make sure the masking of
privatedata to be accessed from unauthorized persons.Managerial data to be tested in this field.
To speed up the SDLC (Software Development Life Cycle)
Software Testing to be done for accelerating the software development process and makes it more
efficient by allowing the quick fix of bugs of the released version of the software application. It can
improve the workflow with the followingadvantages:
More coverage of the browser: Testing to be done for checking the application’s ability to execute in
a parallel manner for the multiple browsers. CrossBrowserTesting checks browser compatibility,
device adaptability,and more.
Less Manual Testing: Browser adaptability is to be checked only with the automation process as
manual testing takes much time for the repeated tasks.
Less Time Consuming: Parallel testing can be done to save the time of testers by implementing
multipletests at the same time.
Increasing the development workflow: Parallel testing makes the testing task easier and it enables
better communication between departments and improves the productivity of the entire team.
Script-less Testing: CrossBrowserTesting enables the testers to run the software testing in a parallel
manner. The record and play option of a testing tool like Selenium is used to achieve parallel testing
with zero scriptor codingskills.
To obtain customer satisfaction

Software Testing is vital to obtain user satisfaction by meeting out their requirements and ensuring
their easy-to-use environment of the application.Itcan be tested with the followingaspects:
Conduct frequent surveys with an end-user to know their expectation and add them during the
development process itself and the testing process should contain therecheck of the addition.
Make sure the close cooperation with an end-user to update the data
Ensure the product quality that should be accepted by the clientas per the services of the application
Monitor the user feedback frequently that can guide the testers on the updation process takes place
in an application even after the deployment.
Software Testing proves the increasing customer satisfaction and helps to obtain their confidence in
our development.
To optimize the business process
Software Testing enables the final product to reach the aim of quality standards before deployment.
It helps the organization to increase the brand image for its profitable growth through reduced
support costs and highly accurate results. The success of an organization depends on embracing
continuous improvement, and the software testing process has no exception. Even the organization
already has a solid software testing operation in place, they should strive to find ways to make it
better still for the improvement of business in all aspects.
Conclusion
Detecting the errors of software is a common incident. Remaining them unaddressed causes serious
issue to the customers of the business and decrease their reputation also. Making the software
application free from errors, testing takes place to obtain the user-experience and cuts down
maintenance costs. Software quality highly depends on its high performance. Hence, the role of
software testing is essential for an organization to deliver quality products. Software Testing will be
done effectively with the skilled professionals and the domain still have many opportunities. Learn
