Lightning can occur between opposite charges within the thunderstorm cloud (intra-cloud lightning) or between opposite charges in the cloud and on the ground (cloud-to-ground lightning). Lightning is one of the oldest observed natural phenomena on earth.
SYSTEM TESTING Fundamentals. DEFINITION. System Testing is a level of the software testing where a complete and integrated software is tested. The purpose of this test is to evaluate the systemâs compliance with the specified requirements. Definition by ISTQB. 1  system testing: The process of testing an integrated system to verify that it meets specified.
In the context of software systems and software engineering, system integration testing (SIT) is a testing process that exercises a software system's coexistence with others.With multiple integrated systems, assuming that each have already passed system testing, SIT proceeds to test their required interactions.here is not that much to do with the application layer when we perform a system integration testing. 1. Mark all the fields from business requirement documents which should be visible in the UI. 2. Create a data map from database fields to application fields and check whether necessary fields are visible in UI.
