A software testing technique contributes to being a specific method, or strategy which is applied for verifying and validating the software under the test. It is possible to reveal various aspects of the software through various test techniques.
The software testing
companies perform the following types of software testing.
Black box technique
In this software testing, the software or application under the test
is referred to as Black Box. In this specific software testing software, the
software tester tests an application without internal working knowledge.
This software application technique focuses on the outputs, which
are generated for certain inputs and executions of the conditions. It is based
on the analysis of the needs of the business and user testing. Black box
testing has also earned the reputation as Opaque Box testing, Functional
testing, and Behavior testing.
Some of the methodologies, involved in black box testing include:
Equivalence partitioning
It is a notable black box testing process which is known to divide
the acceptable inputs domain into different data classes, from which different
test cases are created. Such kind of invalid and valid states for different
input conditions are referred to as Equivalence Class.
Boundary Value Analysis
Every software tester is aware that there are chances of higher
errors across different boundaries, instead of the input domain center for
testing. Owing to this, Boundary Value Analysis contributes to being an
indispensable part of the Black Box Testing technique. Here, the preparation of
different test cases is done, following different guidelines of the testing
technology.
Orthogonal Array testing
It is another prominent software testing system which involves the
testing of pair-wise interaction. Such kind of software testing allows the
design of small test cases tests which offer the maximum coverage of tests. By
following this technique, software testing is capable of categorizing the
faulty logic, which is present in a program, without travelling through the
specifically designed code. This software testing provides the prerequisite
means for the creation of high test coverage for the validation and validating
the software test domain.
To perform such kind of testing, the software tester should have knowledge
about the functional requirements of the software. It is possible to identify
the gaps present between the customer specification and system specification.
In such kind of software testing, the tester and developer work independently.
White-box testing
White box testing is the software testing strategy in which the
software tester needs to have amazing knowledge, about various internal
workings of the software. To conduct such kind of testing, the tester should
perform an examination of the program structure, following the program logic.
White Box testing has earned a reputation as Open Box texting, Clear
Box Testing, Structural Testing, and Glass Box Testing as it imparts a
complementary function to the previous type of testing. Few of the techniques
which are included in White box testing include:
Basis path testing
It is believed to be a kind of white box testing methodology which
comes with the objective of providing the procedural design's logical
complexity measure. Such kind of software testing functions as the guide to
define the execution path's set. This technique ensures that the program's
statement is tested for once at least.
Control structure testing
It is another kind of white box technique in which the focal point
is the control structures, located in the software program. It widens the
testing coverage and brings an improvement in the quality of the testing
technique. Few of the crucial techniques, which are beneficial for control
structure testing, include data flow testing, condition testing, loop testing,
to name a few.
The ultimate objective of condition testing includes the exercise of
different logical conditions, which are present within the program module. This
technique includes the testing of every condition. In addition, it assures that
the entire software testing program does not comprise of bugs and errors.
The data flow testing methodology includes the choice of test path,
according to the variable use and definitions location. Loop testing happens to
be a crucial white box testing methodology which primarily involves the
verification of loop construction. In this kind of software technology,
primarily four different kinds of loops are defined, which include the
unstructured, nested, concatenated, simple and unstructured loops.
Other software testing
techniques
Here the assessment of software quality is performed, following
various quality factors. Various kinds of software testing are meant for the
validation of the software for more quality factors. Few of the different kinds
of software testing techniques include:
Ad Hoc Testing
Software testers adopt this kind of software testing without
pointing to the test case or document. The software testers who are equipped
with the extensive knowledge on the product conduct such kind of testing for
finding different bugs and errors.
GUI testing
This kind of technique is useful in assuring the application's look
and feel. It is also beneficial in verifying and validating the component's
functionality.
Smoke testing
Smoke testing involves a broad and shallow testing approach in which
the tester performs testing of the different areas of the specific software
without deep involving.
Load testing
The primary objective of such kind of testing is determining the
software behavior under overloaded and normal conditions. Certain automated
testing tools are used for the development of artificial loads for finding
various performance problems.
Sanity testing
It is regarded as a deep and narrow technique of software testing,
which includes testing of different areas of the app for determining if the
mobile application works properly, after a change.
Summary
Other software testing techniques are beta testing, alpha testing,
stress testing, performance testing, system testing. It is essential to conduct
software testing at different phases of software development. As you opt for
either of the software as mentioned above testing techniques, you can find the
different bugs and errors, which are predominant in the software testing cycle.
It helps in saving an ample amount of time and money and making software
testing project a grand success.
