Software Testing Definition, Types, Methods

• Software Test Types
• Manual testing manual testing is the process of
  checking the software manually to find the
  defects. Tester should have the perspective of
  end users and ensure that all functions work as
  mentioned in the requirement document. The
  testers execute the test cases and generate the
  reports manually, without automation tools.
• Automation testing automation testing is the
  process of testing the software with an
  automation tool, to find the defects. Testers
  execute the test scripts and automatically
  generate the test results with automation tools.
  Some of the famous automation test tools for
  functional testing are QTP/UFT and selenium.

Test method 1. Static Test 2. Dynamic
Tests Static Tests it is also known as checking
in Software Tests. Verification is a static
method for verifying documents and
files. Verification is the process to ensure
that, whether we build the product correctly,
i.e., to verify the requirements that we have to
check whether we are developing the product
accordingly or not. Dynamic Tests it is also
known as validation in Software Tests. Validation
is a dynamic process for testing the real
product. Validation is the process of whether we
create the right product, ie validate the product
that we have developed is correct or
not. Activities that are involved in testing the
software application

Testing Approaches 1. White Box Test 2.
Black-Box Testing 3. Gray Box Testing
5
White Box Testing it is also called glass box,
Clear Box, structural Tests. White box Tests use
an internal perspective of the system and
programming skills to design test cases. This
check is usually carried out at unit
level. Black Box Testing it is also called
Behavioral / specification-based / Input-Output
Tests. Black Box Testing is a software test
method in which testers evaluate the
functionality of the tested software without
paying attention to the internal code
structure. Grey Box Testing Grey box is the
combination of White Box and Black Box
Testing. The tester working on this type of test
must have access to design documents. This helps
to create better test cases in this process.

Test Levels 1. Unit tests 2. Integration
tests 3. System tests 4. Acceptance
testing
7
Unit Testing Unit Tests are performed to verify
that the individual modules of the source code
are working properly. That is, test each unit of
the application separately by the developer in
the developer environment. It AKA module
examination or partial examination is
Integration Testing Integration Testing is the
process of testing connectivity or data transfer
between a pair of unit tested modules. It is AKA
IT-Tests or String Tests. It is divided in a
Top-down approach, Bottom-Up approach Sandwich
approach (combination of Top-Down and
Bottom-Up). System Testing (end to end test) it
is a black box test. The testing of the fully
integrated application, this will also test as an
end-to-end scenario. To ensure that the software
works in all intended target systems. Check
thorough examination of each input in the
application to check desired outputs. Testing the
user's experience with the application. Acceptanc
e Testing to receive customer logoff so that
software can be delivered and payments can be
received. Types of acceptance tests are Alpha,
Beta and Gamma Tests.

Types of Black Box Tests 1. Function tests
2. Non-Functional Testing

Functional tests in simple terms, what the
system actually does is functional tests. To
verify that each function of the software
application behaves as specified in the request
document. Test all functionalities by entering
them to verify whether the actual output matches
the expected output or not. It falls within the
range of black box Tests and the testers do not
have to worry about the source code of the
application. Non-functional Tests in simple
terms, how well the system performs is
non-functional tests. It refers to various
aspects of software such as performance, stress,
stress, scalability, security, compatibility
etc., emphasis is on improving the user
experience, how quickly the system responds to a
request. For more detailshttps//www.exltech.in/
