We know that inward unit of measurement Testing a unmarried program, unmarried function, unmarried module is tested as well as afterwards that a integration testing is comes where We Testers attempt the integration betwixt several modules as well as nosotros require to ensure that at that topographic point is proper information transmission as well as proper communication happening betwixt the modules. And afterwards integration testing nosotros performs System Testing.
When whole Software is ready as well as integrated together as well as thus nosotros require to perform the System Testing on the software as well as ensure that everything is working equally per the requirements. Here non solely the functional requirement is tested but besides the non-functional requirements are tested. System testing is carried out past times the testing squad as well as to attempt the non-functional requirement testing a specialized testing squad is needed. For representative to perform a functioning testing as well as thus functioning testers are needed. Same amongst safety testing, to perform a safety testing a safety testers are needed.
Understand i thing, inward organisation testing nosotros create non perform all the functional testing types. We solely perform functionality Testing, Regression Testing, Retesting as well as smoke as well as sanity testing, don’t teach confused amongst the diagram. And inward representative of non-functional testing, nosotros ever non require to perform all these shown testing types, it’s totally depends on the clients requirement, but similar a eCommerce site it is needed to perform a functioning testing on it, because when at that topographic point is a exceptional offering or whatever sell is going on eCommerce site as well as thus a heavy traffic is expected. as well as other types of non-functional testing similar safety testing is require to live conducted on Banking software, because inward banking application information of user should live secured, information loss from banking application tin drive a huge coin loss thus it is needed to perform a safety testing on banking application.
First pace of organisation testing is making a Test innovation for the organisation testing. Here all the planning is done similar resources, roles as well as responsibleness of every testing squad mates, as well as thus type of testing that is require to live performed (both functional as well as non-functional), scheduling the attempt activeness etc. all things require to live planned.
Once System attempt innovation is ready as well as thus 2nd pace is to write the attempt cases, dissimilar v-model nosotros don’t write the attempt cases parallel to the evolution phase. Test cases is written against the requirement as well as if whatever functionality is hard to empathize as well as thus the tester may approach the developer, trouble organisation analyst or the managing director or fifty-fifty customer also, to teach the answer of all the queries. Once the Test cases writing piece of job is done as well as thus it’s fourth dimension to execute them against the Software. Here tester require to write the attempt cases for each as well as every requirement. Here nosotros are going to attempt whole software non a item component similar unit of measurement or integration testing. And if at that topographic point is a reach of automation testing as well as thus that the attempt script is created equally per the scenarios as well as requirements. After writing the attempt cases to all attempt cases are executed against the software. The bugs constitute during testing of whole software are reported to developer. After põrnikas fixing sanity, retesting as well as regression testing is done.
There are besides attempt cases written for the non-functional requirement besides .for example, for eCommerce site suppose at that topographic point is i requirement tell software should able to handgrip 5000 concurrent user simultaneously for 1 hour. So to evaluate this requirement testers require to perform different functioning testing type example: Load Testing : hither the software is subjected a 5000 concurrent user for an 1 hour, as well as inward Endurance Testing : the Software is subjected to the 5000 concurrent user but the fourth dimension is extended cast 1 lx minutes to server lx minutes fifty-fifty whole day. And inward Stress Testing : hither the principal aim is to interruption the system, tester increment the user boundary from 5000 to 7-8000 fifty-fifty till the interruption betoken as well as fourth dimension is besides increased inward this functioning testing type as well as lastly Volume Testing : when the database is closed to amount or convey lot of information as well as thus that powerfulness behave upon the organisation as well as it brand dull downward the organisation thus that is besides require to attempt how organisation performs nether the heavy data. With the similar means the safety as well as other non-functional types of testing is conducted past times the specialized Testers. Based on the scope.
Main Points :
- System Testing is performs afterwards the integration testing.
- System Testing is performed on fully integrated Software.
- In System Testing Functional as well as Non-functional both the facial expression is tested.
- To perform non-functional testing a Specialized Testers are requires.
