Software testing methodologies comprise different approaches and strategies for testing an app or product. It helps in ensuring that the software is performing as it is intended to. There is a plethora of software testing methodologies, which are used by the business organization.
Some of the primary software testing methodologies are as follows.
Unit testing
It is regarded as the primary level of software testing. In this
methodology, it is possible to ensure that different components of the
software, present at the code level are working and functioning in the way they
are supposed to.
Developers, present in the test-driven environment, will be running
the tests before the software. Unit testing is useful in making the process of
debugging easy. It is because as the problems are detected at an earlier phase,
they will be resolved in no time.
Non-functional and
functional testing
The ultimate objective of different software testing methodology in
the development phase is ensuring that the software can operate successfully
across various platforms and in several environments. It is further divided
between non-functional and functional testing.
Speaking of functional testing, it involves the testing of the
specific product against the needs of the business. It is known to incorporate
different test types, which are meant to ensure that every part of the business
behaves as per the use cases offered by the business analyst or design team.
Such kind of software testing methodology includes integration testing, unit
testing, acceptance testing, and system testing.
The performance of non-functional testing methodologies involves the
incorporation of different test types focused on different operational aspects
of the software. It is inclusive of security testing, performance testing,
compatibility testing, and usability testing.
System testing
System testing contributes to being a black box testing methodology
which is used for evaluating the integrated and complete system to assure that
it has accomplished certain needs. In this software testing methodology,
specific software is tested from end to end. The software testing team
accomplishes this kind of testing before the product is released into the
market.
Integration testing
In this kind of testing, every unit is tested thoroughly. After this, it is integrated with different units for the generation of components and modules, which are meant for performing different activities and tasks. After this, the testing is performed as the group to assure that the application or product's segments are behaving, according to the expectations.
Such kind of software testing services is framed by the user scenarios, like the opening
of the files and logging into the app. Only independent software testers and
developers perform such kind of testing. It is primarily the combination of
different manual and automated functional tests.
System testing
System testing contributes to being a black box testing methodology
which helps evaluate the integrated and completed system to assure that it has
accomplished different needs. Here, the testing of the software functionality
is done end to end. A separate testing team performs this kind of testing
before the beginning of the production process.
Acceptance testing
Acceptance testing is the last stage of functional testing which is
beneficial in assessing if the last part of the application is ready for the
release. Through such kind of testing, the tester checks if the developed
software satisfies the criteria of the original data. It also validates if the
software has accomplished different needs of the software. In such kind of
testing, the application is tested externally and internally.
Performance testing
It is a non-functional testing methodology which is used for
checking how the specific app behaves under different circumstances. The
ultimate objective of such software testing methodology is testing the
stability and responsiveness in different real user circumstances. It is
possible to break the performance testing into four kinds which include stress
testing, load testing, spike testing, and endurance testing.
Security testing
With the increase in cyberattacks and cloud-based testing platforms,
there is an increasing need for data security in the software. Security testing
contributes to being a non-functional software testing methodology which is
beneficial in checking if the data and information within the system are
protected.
The ultimate objective of software testing is finding the security
risks and loopholes within the system, which might result in information loss
or unauthorized access to the information. There are different kinds of such
testing methodology which includes confidentiality, integrity, authorization,
authentication, non-repudiation, and availability.
Usability Testing
Usability testing is a testing methodology which ensures if the
product can be used at ease from the end-user point of view. This kind of
software testing is accomplished during the phases of acceptance testing and
system testing.
The ultimate objective of software testing is determining if the
aesthetics and visible design of the product are accomplishing the workflow,
which is intended for different techniques. It is believed to be an integral
part of the software testing methodology, which is beneficial in reviewing
different separate functions.
Compatibility testing
In this methodology of software testing, the tester measures how
specific application functions under various environments. It is beneficial in
checking if the specific application or product has compatibility with the browsers,
platforms, operating systems, and resolution configuration. The ultimate
objective of this kind of software testing is ensuring that the functionality
of the software is supported consistently across a certain environment.
Agile testing
Agile contributes to being a crucial software development methodology which has become widely popular in the past few years. By choosing this software methodology, software developers can create software incrementally.
They are known to break the projects into the user
functionality's segments, give more priority to them, and deliver the same in
cycles of two weeks. Such kind of testing methodology is known to be
incremental. Here, the testing of every small release is done to assure optimum
quality.
Software testing companies which are testing the software can perform either of the
methodology as mentioned above to make the process of software development a
grand success.
