ABOUT SOFTWARE TESTING
Software testing is the primary process of verifying and
validating the software program or the product. It is also an
investigation which is conducted to offer stakeholders with
required information about service test or the product quality. It
has a view that the software allows you to check out the
software implementation by understanding and appreciate it.
On the other side, usually, the test techniques majorly include
the program to execute and find the errors to check out
whether the product is ready to use or not.
QUALITY TESTING
It includes activities that ensure the identification
of bugs/error/defects in a software.
Focuses on actual testing.
Product-oriented activities.
It is a preventive process.
Testing is the subset of Quality Control.
QUALITY ASSURANCE
QA includes activities that ensure the implementation of
processes, procedures and standards in context to verification
of developed software and intended requirements.
Focuses on processes and procedures rather than conducting
actual testing on the system.
Process-oriented activities.
Preventive activities.
It is a subset of Software Test Life Cycle (STLC).
QUALITY CONTROL
It includes activities that ensure the verification of a
developed software with respect to documented (or not
in some cases) requirements.
Focuses on actual testing by executing the software
with an aim to identify bug/defect through
implementation of procedures and process.
Product-oriented activities.
It is a corrective process.
QC can be considered as the subset of Quality
Assurance.
ISO STANDARDS Many organizations around the globe develop and implement different standards to improve the quality needs of their software. This chapter briefly describes some of the widely used standards related to Quality Assurance and Testing.
ISO/IEC 9126 ISO/IEC 9241-11 ISO/IEC 25000:2005 ISO/IEC 12119
ISO/IEC 9126 This standard deals with the following aspects to determine the quality of a software application:Quality model,External metrics,Internal metrics,Quality in use metrics
quality attributes for any software such as: Functionality,Reliability,Usability,Efficiency, Maintainability,Portability
ISO/IEC 9241-11 Part 11 of this standard deals with the extent to which a product can be used by specified users to achieve specified goals with Effectiveness, Efficiency and Satisfaction in a specified context of use.
This standard proposed a framework that
describes the usability components and the
relationship between them.
the usability is considered in terms of user
performance and satisfaction.
ISO/IEC 25000:2005
ISO/IEC 25000:2005 is commonly known as the standard that provides the guidelines for Software Quality Requirements and Evaluation (SQuaRE). ISO-25000 replaces the two old ISO standards, i.e. ISO-9126 and ISO-14598.
ISO/IEC 12119 This standard deals with software packages delivered to the client. It does not focus or deal with the clients’ production process.
The main contents are related to the following items:
Set of requirements for software packages. Instructions for testing a delivered software package against the specified requirements.
TYPES OF TESTING
The testing has the different types of testing which are
mainly used to test software.They are
Manual Testing
Automation Testing
MANUAL TESTING
Manual testing includes the testing of software
manually which means without using any of the
automated script or the tool. In this manual testing
type, the tester will take over the testing to check out
whether there is an identity of any unexpected errors
or behavior occurs.
AUTOMATION TESTING
Test Automation, whereas on the other side tester
which will help to write the scripts and it uses the
other software which is use to test the product. Thus
the process involves the manual process of its
automation. It also helps to re-run the performance to
look for scenarios which are performed quickly,
manually and the repeatedly.
METHODS The software methods are used for the testing software purposes.
There are different methods that can be used for software testing.:
Black-Box TestingWhite-Box Testing Grey-Box Testing
BLACK-BOX TESTING
The internal workings of an application need not be known.
Also known as closed-box testing, data-driven testing, or functional testing.Performed by end-users and also by testers and developers. Not suited for algorithm testing. Testing is based on external expectations - Internal behavior of the application is unknown. This can only be done by trial-and-error method.
WHITE-BOX TESTING
Tester has full knowledge of the internal workings of the application.
Also known as clear-box testing, structural testing, or code-based testing. Normally done by testers and developers. The most exhaustive and time-consuming type of testing. Suited for algorithm testing. Data domains and internal boundaries can be better tested.
GREY-BOX TESTING
The tester has limited knowledge of the internal workings of the application.
Also known as translucent testing, as the tester has limited knowledge of the insides of the application. Performed by end-users and also by testers and developers. Partly time-consuming and exhaustive. Not suited for algorithm testing. Data domains and internal boundaries can be tested, if known.
LEVELS
The online software testing course has two different level testing. The level of testing which mainly includes the different method that is used during the software testing. The two main levels are,
Functional Testing Non-functional Testing
FUNCTIONAL TESTING
Functional Testing is the type of black box
testing which is based on the software
specifications to be tested.
Thus the application is tested by the results and
the inputs according to the functionality.
Functional testing of the software is placed on
the integrated system to correct the system’s
observance with requirements.
NON-FUNCTIONAL TESTING
Non-Functional Testing is based on testing the
application from its attributes.specifications to
be tested.
It mainly involves the software testing from the
given requirements as well.
DOCUMENTATION
The software Testing documentation is an IEEE standard specifies the set of documents for the primary use in different defined stages of system testing and software testing. There are different types of documents are
Test Plan Test Scenario Test Case Traceability Matrix
TEST PLAN
A Test Plan includes the following:
Introduction to the Test Plan document Assumptions while testing the application List of test cases included in testing the application List of features to be tested What sort of approach to use while testing the software List of deliverables that need to be tested The resources allocated for testing the application Any risks involved during the testing process A schedule of tasks and milestones to be achieved
TEST SCENARIO
It is a one line statement that notifies what
area in the application will be tested.
Test scenarios are used to ensure that all
process flows are tested from end to end.
A particular area of an application can have as
little as one test scenario to a few hundred
scenarios depending on the magnitude and
complexity of the application.
TEST CASE Test cases involve a set of steps, conditions, and inputs that can be used while performing testing tasks. components are always available and included in every test case:
Test case ID Product module Product version Revision history Purpose Assumptions Pre-conditions Steps Expected outcome Actual outcome Post-conditions
TRACEABILITY MATRIX
Traceability Matrix (also known as Requirement Traceability Matrix - RTM) is atable that is used to trace the requirements during the Software Development Life Cycle. The main goals for this matrix are:
Make sure the software is developed as per
the mentioned requirements.
Helps in finding the root cause of any bug.
Helps in tracing the developed documents
during different phases of SDLC.
ESTIMATION TECHNIQUES
The testing has the estimation which is mainly required
one of the important things in SDLC.
Based on the correct estimation it will help the
software testing process with the perfect coverage.
Functional point analysis is based on the analysis of
user requirements of software with the various
categories like outputs, inquiries, inputs, Internal files,
External files.
Test point analysis is used with estimation process for
acceptance testing or black box.Software testing online
courses explain clear concepts of testing.
