Software Testing and why are there separate organizations to do that

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.

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.


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.
