What is System testing?When testers complete testing (The testers test the application in the test environments, meaning they test with the test data only, NOT with the real data), the application (software) has to be tested in the real environment. What it means is, since the testers test it in the test environment with the test data, we have to make sure that the application works well in the real environment with the real data. In test environment, some of the things cannot be simulated or tested. Al though the test environment is very similar to the production (real) environment, we need to make sure that we get a smooth delivery in the real system as well (As servers are different and database is different, things may not work as expected when the application is moved from test environment to production environment)

What is Load testing?It is a test to check the user’s response time for number of users using any one scenario (single business process) of the same application at the same time.
