    Mutation testing
    - It is a structural testing technique, that uses the structure of the code to guide the testing process.

    - On higher level, it is the process of rewriting the source code in small ways so that the redundancies are removed from the source code.

    - These ambiguities may cause failures in the software and if not fixed they can easily pass through testing phase undetected.

    Unit testing
    - The smallest testable part of an application like functions, classes, procedures, interfaces is a unit.

    - This testing is a method by which individual units of source code are tested to determine if they are fit for use.

    - These tests are basically written and executed by software developers to make sure that code meets its design and requirements and behaves as expected.

    - The goal of this testing is to segregate each part of the program and test so that the individual parts are working correctly.

    - This means that for any function or procedure when a set of inputs are given then it should return the proper values.

    - The failures should be handled properly during the course of execution when any invalid input is given.

    Beta testing
    - This testing is also known as field testing.

    - They take place at customer’s site.

    - They send the system to users who install it and use it under real-world working conditions.

    - It is the second phase of software testing in which a sampling of the intended audience tries the product out.

    - Originally, the term alpha test meant the first phase of testing in a software development process.

    - First phase includes the unit testing, component testing, and system testing.

    - This testing can also be considered “pre-release testing.

    Stress testing
    - It is a software testing activity that determines the robustness of software by testing beyond the limits of normal operation.

    - It is particularly important for "mission critical" software, but is used for all types of software.

    - They commonly put a greater emphasis on robustness, availability, and error handling under a heavy load, than on what would be considered correct behavior under normal circumstances.
