2.      Agile Methodology

3.      Scrum Framework

4.      Comparison of Waterfall model with Agile Methodology

5.      Comparison of V Model with Agile Methodology

Quality: Delivering Bug Free Application within the timeline and within the budget

How to Deliver Quality Software?

1.      Explain differences between Alpha Testing and Beta Testing?

Ans:  1. these types of testing comes under UAT Testing

Alpha Testing: Testing of a software product by the customer at development environment for acceptance criteria

Beta Testing: Testing of a software product by the customer at customer environment for acceptance criteria

Note: Client/End users in Alpha and Beta Testing

Explain differences between White box Testing and Black Box Testing?

Ans: Testing Methodologies

Definition:

1.      Test application by knowing internal logic/programming logic is called as white box Test methodology

2.       Developers/Testers with programming knowledge can do Unit Test/Integration Test by using white box Testing methodology

3.      White box Testing will be performed with different Techniques

1.      Statement coverage: Executing each statement in the program to test that statement output is correct or not

2.      Conditional coverage: Executing different  conditional statements

3.      Branch coverage: Executing each loop

4.      Memory leakage: Test program execution speed

Ex: Eliminate various which are not required/Optimize usage of multiple if conditions

Note: White box Testing can be also called as “Glass box Testing” or “Clear Box Testing”

Black box Testing:

Black box testing is a strategy/Methodology in which testing is based solely on the requirements and specifications. Unlike its complement, white box testing, black box testing requires no knowledge of the internal paths, structure, or implementation of the software under test (SUT).

The general black box testing process is:

·         The requirements or specifications are analyzed.

·         Valid inputs are chosen based on the specification to determine that the SUT processes them correctly. Invalid inputs must also be chosen to verify that the SUT detects them and handles them properly.

·         Expected outputs for those inputs are determined.

·         Tests are constructed with the selected inputs.

·         The tests are run.

·         Actual outputs are compared with the expected outputs.

·         A determination is made as to the proper functioning of the SUT

Black Box Testing Techniques:

1.      Equivalence Partitioning

2.       Boundary Value Analysis

3.      Decision Table

4.      Error Guessing

5.      Use case Testing

What are the Benefits of White box Testing and Black box Testing?
