In order to make sure that the real software product meets the expectations of its users as well as to make sure that the product is free of errors, Software Testing is a process. As part of this process, software/system components are analyzed using either manual or automated tools in order to evaluate one or more properties of interest in software/system components. Testing of software consists of identifying errors, gaps, or missing requirements in contrast to the actual requirements in order to detect errors, gaps, or missing requirements.
As the name implies, software testing is the process of verifying and validating whether a software or application is bug-free, whether it meets the technical requirements as specified by its design and development, and whether it meets the user requirements as effectively and efficiently as possible by addressing all the exceptions and boundary cases that may arise.
There are a variety of reasons why software testing is conducted, not only for the purpose of identifying faults in the existing software but also for the purpose of finding ways to improve the software in terms of efficiency, accuracy, and usability. A software program or application is primarily evaluated based on its specifications, functionality, and performance, which in turn is used to identify its shortcomings.
It is possible to divide the process of software testing into two steps:
1. Verification: An implementation test refers to a set of tasks designed to ensure that the software implements a particular function correctly.
2. Validation: Software traceability refers to ensuring that the software built is in accordance with customer requirements.
Verification: What is the right way to build the product?
Validation: What is the best product we can build?
Is there a difference between different types of software testing?
There are two types of software testing
1. Manual Testing: Software should be tested manually, without being automated or scripted. This type of test involves the tester acting as an end user and identifying any unexpected behavior or bug in the software. Manual testing has different stages, such as unit testing, integration testing, system testing, and user acceptance testing.
The purpose of test plans, test cases, and test scenarios is to ensure that the testing of software is as thorough as possible. As part of manual testing, testers explore the software to identify errors.
2. Automation Testing: An automation tester writes scripts and uses another software to test the product using automation testing, also known as Test Automation. This process automates a manual process. Test scenarios previously performed manually in manual testing are re-run using automation testing quickly and repeatedly.
Automated testing also includes load, performance, and stress testing for applications in addition to regression testing. Compared to manual testing, it will increase test coverage, improve accuracy, and save you time and money.

How can you test software using different Software Testing Techniques?
There are two major categories of software testing techniques
1. Black Box Testing: A black-box test is conducted at the software interface without concern for the internal logical structure of the software and without access to the source code.
2. White-Box Testing: White-box testing is a technique of testing in which the tester is aware of the internal workings of the product, has access to its source code, and ensures that all internal operations conform to specifications.
In software testing, what are the different levels?
There are four major levels of software level testing:
1. Unit Testing: Individual components or units of a software/system are tested as part of the software testing process. In this test, each unit of the software is validated to ensure it performs as intended.
2. Integration Testing: A stage in the software testing process where individual units are combined and tested together. A fault in the integration between units is exposed by this level of testing.
3. System Testing: A level of software testing that involves testing an integrated system or software as a whole. This test evaluates whether the system meets the specifications.
4. Acceptance Testing: In software testing, acceptance testing is used to determine if a system is acceptable. During this test, the system is evaluated for compliance with business requirements and whether it is suitable for delivery.
