In
the Software industry, testing is an extremely important process and an
integral part of the software development cycle. Software testing assesses the
functionality of a software application, aiming to find whether the developed
software has met the specified requirements or not. So, a software testing company usa performs the exact same function along
with the responsibility of identifying the weaknesses within the software so as
to ensure that the product is error-free, and has the best quality.
Many
software development companies, therefore, handle the testing task to the software
testing companies usa. Outsourcing of the software testing allows
companies to focus on their main functions and driving innovation. Meanwhile,
the testing service providers operate productively & efficiently, ensuring
high-grade quality and a positive trade outcome. It saves the time and capital
of the organization regardless of the project scope and frequency of testing
needs.
Now,
let's get to know what exactly is constituted by Software Testing and the
various terms and processes within this domain.
Types:
Manual Testing - This process of
testing the software is, to manually find the deficiencies. Here, a tester
should hold the perspective of an end-user and ensure that all the features are
working as per the requirement specification. In this process, the test cases
and the manually generated reports are significant in giving the result.
Automation Testing - Automation testing
tests the developed software using automation tools to trace the errors. In
this, the testers perform the test scripts and generate the test results
automatically with the help of tools. Some famous computerized testing tools
available are QTP/UFT, and Selenium.
Methods:
Static Testing – It is a testing
technique in which the software is tested without executing the code. It has
two segments as posted below:
1)
Review - Mainly, used to locate and kill errors or ambiguities in specific
documents such as requirements, test cases, design, etc.
2)
Static analysis - The program coded by the developers is analyzed (mostly by
tools) for skeletal defects.
Dynamic Testing - For performing
dynamic testing, the software should be compiled and executed. Then only, the
software can be analyzed on the basis of parameters such as memory usage,
response time, CPU usage, and overall performance. Also, this process involves
testing the software using input values and the output produced, is analyzed.
Testing Approaches:
White Box Testing - To examine the
program structure and derive test data from the program logic/code, this
testing technique is employed. This approach is also known as glass box
testing, open box testing, clear box testing, path driven testing or logic
driven testing or structural testing.
Black Box Testing - Black-box testing
is a method of testing the software, in which it examines how well the
application fulfills its purpose, based on the specifications. Its other name
is Specifications based testing.
Grey Box Testing -
Grey Box testing is a technique that tests the software with bounded
information about its actual functionality. So, Grey Box testers have
permission to refer to the detailed design documents along with the requirement
sheet.
