Software Testing Questions

Impact Analysis is used in software testing to define all the risks associated with any kind of changes in a product being tested.

Impact Analysis is nothing but analyzing the impact of changes in the deployed product or application. It gives the information about the areas of the system that may be affected due to the change in the particular section or features of the application.

Why Impact Analysis is done :

1. It is done to understand the possible outcome of implementing the change. Inducing too much functionality into a product can reduce the overall performance of the product.

2. To identify all the files, documents and models that might have to be modified if team decides to implement the change in product

3. To estimate the effort needed behind implementing the change

4. To identify the task required to implement the change

5. It will list the dependencies on a specific element

The impact is analyzed on Requirements, Design & Architecture, impact on Test and impact on schedule.

Sequential is the simplest file structure

Full binary tree loses its nature when operations of insertions and deletions are done. For incomplete binary trees, extra storage is required and overhead of NULL node checking takes place. So complete binary tree is the better one since the property of complete binary tree is maintained even after operations like additions and deletions are done on it.

Structural Testing is the other name for White Box Techniques.

BackTracking is used for solving N-Queens problem

Data flow analysis studies the use of data on paths through the code.

Component Testing is also called as Module or Unit or Program testing. It is testing of all the components in an application separately.
