The rule of a Test Driven Development is to prepare test cases before writing the actual code. Which means you are actually be writing code for the tests before you write code for the application.

Explain what is the difference between Regression testing and Retesting?

Retesting is carried out to check the defects fixes, while regression testing is performed to check whether the defect fix have any impact on other functionality.

 Set appropriate bug priority

Explain what are test driver and test stub and why it is required?

The stub is called from the software component to be tested, it is used in top down approach
 The driver calls a component to be tested, it is used in bottom up approach
 It is required when we need to test the interface between modules X and Y and we have developed only module X. So we cannot just test module X but if there is any dummy module we can use that dummy module to test module X
 Now module B cannot receive or send data from module A directly, so in these case we have to transmit data from one module to another module by some external features. This external feature is referred as Driver

What is Ad Hoc testing?

It is a testing phase where the tester tries to break the system by randomly trying the system’s functionality. It can include negative testing as well.

What is configuration management?

It is a process to control and document any changes made during the life of a project. Release control, Change control and Revision control are the important aspects of configuration management.

What is thread testing?

A thread testing is a top-down testing, where the progressive integration of components follows the implementation of subsets of the requirements, as opposed to the integration of components by successively lower levels.

What is validation and verification in software testing?

In verification, all the key aspects of software developments are taken in concern like code, specifications, requirements and document plans. Verification is done on the basis of four things list of issues, checklist, walkthroughs and inspection meetings. Following verification, validation is done, it involves actual testing, and all the verification aspects are checked thoroughly in validation.

What are the five common solutions for software developments problems?

Setting up the requirements criteria, the requirements of a software should be complete, clear and agreed by all
 The next thing is the realistic schedule like time for planning , designing, testing, fixing bugs and re-testing
 Adequate testing, start the testing immediately after one or more modules development.
 Use rapid prototype during design phase so that it can be easy for customers to find what to expect Use of group communication tools

Explain stress testing, load testing and volume testing?

Load Testing: Testing an application under heavy but expected load is known as Load Testing. Here, the load refers to the large volume of users, messages, requests, data, etc.
 Stress Testing: When the load placed on the system is raised or accelerated beyond the normal range then it is known as Stress Testing.
 Volume Testing: The process of checking the system, whether the system can handle the required amounts of data, user requests, etc. is known as Volume Testing.

What is Agile testing and what is the importance of Agile testing?

Agile testing is software testing, which involves the testing of the software from the customer point of view. The importance of this testing is that, unlike normal testing process, this testing does not wait for development team to complete the coding first and then doing testing. The coding and testing both goes simultaneously. It requires continuous customer interaction.
 It works on SDLC ( Systems Development Life Cycle) methodologies, it means that the task is divided into different segments and compiled at the end of the task.

Explain the steps for Bug Cycle?

Once the bug is identified by the tester, it is assigned to the development manager in open status
 If the bug is a valid defect the development team will fix it and if it is not a valid defect, the defect will be ignored and marked as rejected
 The next step will be to check whether it is in scope, if it is happen so that, the bug is not the part of the current release then the defects are postponed
 If the defect or bug is raised earlier then the tester will assigned a DUPLICATE status
 When bug is assigned to developer to fix, it will be given a IN-PROGRESS status
 Once the defect is repaired, the status will changed to FIXED at the end the tester will give CLOSED status if it passes the final test.
