1. Explain Alpha testing?

Alpha testing: is performed by the IN-House developers. After alpha testing the software is handed over to software QA team, for additional testing in an environment that is similar to the client environment.

2. Explain What is alpha and beta testing?

Alpha testing: is performed by the IN-House developers. After alpha testing the software is handed over to software QA team, for additional testing in an environment that is similar to the client environment.

Beta testing: It is performed by end user. So that they can make sure that the product is bug free or working as per the requirement. IN-house developers and software QA team perform alpha testing. The public, a few select prospective customers or the general public performs beta testing.

3. Do you know What is regression testing?

Regression Testing: When changes in the code of the software are made to fix the previous bug. Then testing needs to be perform to ensure that it will not generate a new bug in the application and it works as specified and that it has not negatively impacted any functionality that it offered previously. Regression Testing is important because of following reason:

That the application works even after the alteration in the code were made.
The original functionality continues to work as specified even after doing changes in the software application.
The alteration to the software application has not introduced any new bugs.

4. Do you know What is data driven testing?

Data Driven is an automation testing part in which test input or output values, these values are read from data files. It is performed when the values are changing by the time. The different data files may include data pools, csv files, Excel files. The data is then loaded into variables in recorded or manually coded scripts. For data driven testing we use Parameterzing and Regular expression Technique.

Ex: To evaluate login functionality, we use different user name and password combinations, variables are used to access different username and password. The list of username and password are stored in a data table or excel sheet.

5. What is Bug release?

Bug release: is when a build is handed to testing team with knowing that defect is present in the release. The priority and severity of bug is low. It is done when customer want the application on the time. Customer can tolerate the bug in the released then the delay in getting the application and the cost involved in removing that bug. These bugs are mentioned in the Release Notes handed to client for the future improvement chances.

6. What is Bug Leakage?

Bug Leakage: When customer or end user discovered a bug which can be detected by the testing team. Or when a bug is detected which can be detected in pervious build then this is called as Bug Leakage.

7. Explain bug leakage and bug release?

Bug Leakage: When customer or end user discovered a bug which can be detected by the testing team. Or when a bug is detected which can be detected in pervious build then this is called as Bug Leakage.

Bug release: is when a build is handed to testing team with knowing that defect is present in the release. The priority and severity of bug is low. It is done when customer want the application on the time. Customer can tolerate the bug in the released then the delay in getting the application and the cost involved in removing that bug. These bugs are mentioned in the Release Notes handed to client for the future improvement chances.

8. What is the basis for choosing the SDLC model for development of software?

The choice of SDLC depends on the various factors, how stable are the requirements:

When the requirements are very clearly know, documented and not subject to change then we can follow the waterfall model.
Most of the companies follow the V mode for the development because this model includes both verification and validation activities and testing is involved in earlier phase.
Iterative model can be used to build application where requirement changes after a period of times or application features or added on with smaller release. When the client is ready for the delivery of the product in parts or phases.

9. Why you choose automated testing over manual testing?

The reasons for choosing automation testing over manual testing are following:

1. Frequency of use of test case
2. Time Comparison (automated script run much faster than manual execution.)
3. Reusability of Automation Script
4. Adaptability of test case for automation.
5. Exploitation of automation tool.

10. What are the key challenges of software testing?

Following are some challenges of software testing

1. Application should be stable enough to be tested.
2. Testing always under time constraint
3. Understanding requirements, Domain knowledge and business user perspective understanding
4. Which tests to execute first?
5. Testing the Complete Application
6. Regression testing
7. Lack of skilled testers.
8. Changing requirements
9. Lack of resources, tools and training
