The levels of software testing involve the different methodologies, which can be used while we are performing the software testing.
In software testing, we have four different levels of testing, which are as discussed below:

• 
  Unit Testing
  
• 
  Integration Testing
  
• 
  System Testing
  
• 
  Acceptance Testing
  

Unit testing is the first level of software testing, which is used to test if software modules are satisfying the given requirement or not.
The first level of testing involves analyzing each unit or an individual component of the software application.


The second level of software testing is the integration testing. The integration testing process comes after unit testing.
It is mainly used to test the data flow from one module or component to other modules.


The third level of software testing is system testing, which is used to test the software's functional and non-functional requirements.
It is end-to-end testing where the testing environment is parallel to the production environment. In the third level of software testing, we will test the application as a whole system.


The last and fourth level of software testing is acceptance testing, which is used to evaluate whether a specification or the requirements are met as per its delivery.
The software has passed through three testing levels (Unit Testing, Integration Testing, System Testing). Some minor errors can still be identified when the end-user uses the system in the actual scenario.

In formal testing, the degree of thoroughness and formality of test cases depend upon the requirements of the project. Formal testing follows a systematic process called Software Testing Life Cycle (STLC).
There are multiple steps taken in formal testing:

• 
  Requirement Analysis.
  
• 
  Planning about tests.
  
• 
  Documentation of Test Cases.
  
• 
  Setting up the Test Environment.
  
• 
  Execution of Tests.
  
• 
  Closure of Tests.
  

There are two ways for testing software. One is the traditional manual testing way and the other one is the automated testing way. We can use traditional manual testing for both formal testing of the software and informal testing of the software. However, the automated testing method is only suitable for formal testing of software because of the defining set of rules.

• 
  Manual Testing: It is done with a person’s help, by clicking and interacting with the software using proper tools. The process is prone to error since it requires someone to set up an environment and perform the tests themselves. Since the testers are human it is prone to human error as the tester might make spelling mistakes or maybe skip the steps described in the test script.
  
• 
  Automated Testing: It is done with the help of machines that runs a test script that is already written for it in advance. These tests can differ in complexity. Automated testing is much more robust and reliable than manual testing but the quality of tests depends upon how the test scripts were written for the machine.
