2How U Do The Back End Testing In QTP?

Ans: First of all we have to know what back end is testing. Back end testing is nothing but checking the correctness of the Database.
With QTP we can write a script which going to connect the
Backend I mean a database of our inquiry then we can set it on the Datatable where we can compare the backend data with
The real one and determine If there is any inconsistency and so on so forth.

3How To Do Testing For Performance Related Issues?

Ans: Testing can be done whether indexes have been created on particular table or not,as indexes are used to increase the performance.

4What Are Pros Of Back End Testing?

Ans:
PROS:

1. The back end is no longer a “black box”
to testers. Many bugs can be effectively found and fixed in the early development stage. Take Forecast LRS as an example; the number of bugs in a back
end was more than 30% of total number of bugs in the project.
2. When back end bugs are fixed, the system quality is dramatically increased.

5How To Do Functional Testing in Backend?

Ans: A back end structure is divided into number of tests
Based on application functionality. The tests focus input and output conditions but not structure or implementation.

6How To Do Boundary Testing In Backend?

Ans: To check the boundary conditions of columns.

7How To Do Stress Testing In Backend?

Ans: Testing database under heavy loads.
e.g.: testing the table which has large number of records
Used by number of users at the same time.

8How Are Integration Tests Done In SQL Server?

Ans: Integration tests should be performed after the above component testing is done. It should call stored procedures intensively to select, update, insert and delete records in different tables and different sequences.

The main purpose is to see any conflicts and incompatibility.

  • Conflicts between schema and triggers
  • Conflicts between stored procedures and schema
  • Conflicts between stored procedures and triggers

9What Is Benchmark Testing?

Ans: When a system does not have data problems or user interface bugs, system performance will get much attention. The bad system performance can be found in benchmark testing.

Four issues must be included:

  • System level performance
  • Major functionality (Pick up most-likely-used functions/features)
  • Timing and statistics (Minimal time, maximal time and average time)
  • Access volume (A large number of machines and sessions must be involved.)

Ans: here are several phases in back end testing. The first step is to acquire design specifications for an SQL server. The second step is test specification design. The next step is to implement the tests in this design with SQL code. The test sp...  read more
