Testing a system after it has been coded, unit tested, and usually undergone intergration testing. Test cases are written from documentation (functional spec, business rules etc..) and then executed to confirm the software will meet requirments.
System testing is the type of testing to check the behavior of a complete and fully integrated software product based on the software requirements specification (SRS) document. Its a series of different tests whose sole purpose is to exercise the full computer based system. In SDLC, System Testing is perform as the first level of testing where the system is tested as a whole. In System Testing, we test the both Functional as well as Non Functional parameters of Software Testing. System testing involves testing of following: Testing the fully integrated applications including external peripherals in order to check how components interact with one another and with the system as a whole. This is also called End to End testing scenario. Verify thorough testing of every input in the application to check for desired outputs. Testing of the user's experience with the application. . That is a very basic description of what is involved in system testing. You need to build detailed test cases and test suites that test each aspect of the application as seen from the outside without looking at the actual source code. Every software testing company consider all these things while performing system testing.
Support testing typically refers to system testing, which evaluates the overall functionality and performance of a system in a controlled environment. This type of testing ensures that the system meets specified requirements and is capable of handling expected user loads and operational conditions. Additionally, it may involve user acceptance testing (UAT) to gather feedback from end-users on the system's usability and support. These tests help identify any issues that could affect the system's reliability and supportability.
Where the testing is done by the domain expert without the knowledge OS current System Requirement Specifications is know as adoch testing
The system testing phase should begin once the individual components of the software have been integrated and the system is in a stable state. This typically follows the completion of unit and integration testing, ensuring that all parts work together correctly. System testing aims to validate the overall functionality, performance, and compliance with requirements before the software is deployed. It's crucial to conduct this phase before moving to user acceptance testing (UAT).
At Lovely Professional University (LPU), the concepts of software testing and program testing are typically taught as part of the Computer Science Engineering (CSE) and Information Technology (IT) curricula. While the terms may seem similar, they represent different aspects of quality assurance and debugging in the software development lifecycle.Software testing is the broader process of evaluating and verifying that a software application or system behaves as expected. It involves checking whether the software meets the specified requirements and functions correctly in all scenarios. Program testing focuses on testing individual programs or code snippets in isolation to verify their correctness. It is typically a smaller, more specific part of the broader software testing process. Program testing is mostly concerned with ensuring that specific functions, modules, or individual code blocks work correctly. At LPU, the distinction between software testing and program testing lies in their scope and focus. Software testing is a broader concept that encompasses all types of testing for the entire system, including testing its performance, functionality, and integration. Program testing, on the other hand, is more focused on testing individual components or code blocks (like functions or methods) to ensure they work correctly before integration into the larger system. Both processes are critical for ensuring the quality and reliability of software, and students at LPU will likely learn about both in their CSE or IT courses, using modern tools and techniques to test software effectively.
Validation testing is to test software if it meets its stated requirements. System testing is the testing of Software and Hardware together and to find out they both can work together to be successful application.

System testing has classifications like functional and non functional testing. Hence the functional testing is a part of system testing. System testing allows the testers to test the typical end product. Every single module, interface and every minute detail are needed to be tested in system testing. Functional testing is aimed at testing the functionalities of the product being tested. These functionalities include volume, stress, load, security, scalability, performance etc. Hardware and software is not concerned with functional testing. Functional testing involves testing of functional requirements as per the specification. On the other hand, system testing involves testing the system as a whole. This may involve testing of proper installation and uninstalling of the application. System testing tests for all internal and external components that make the system.

system testing
system testing is a kind of retesting where we can test whole system after integration. while regression testing is a process where we do the rerunning the test cases and check whether that re run doesnot affects the real environment.
These are the next testing levels after unit testing: 1 Integration testing 2 Component interface testing 3 System testing 4 Operational Acceptance testing
Module testing - (or unit testing) is testing a single module. Its just testing the tyre of a car. If all screws are tight, air pressure is fine. System Testing - System is tested as a whole. You may say that it is integration testing when last component is added. Just like if all tyres and everything else is attached in car, and then we test it. We test if all together is working fine or not.
System testing is a phase in software testing where the entire system is evaluated as a whole to ensure it meets specified requirements. It aims to identify defects or issues in the integrated software environment and validate its functionality, performance, and security. This testing type checks the interactions between various components and verifies that the system behaves as expected under different conditions. Ultimately, system testing ensures that the software product is ready for deployment and meets user needs.
Testing a specific part of a system or even a program. That would be called a component. So it is component testing.
Seriously? 20 million man hours of hard slog and testing,testing, testing.
