What is Test ........?

 1. What is Test Bed?
An execution environment configured for testing. May consist of specific hardware, OS, network topology, configuration of the product under test, other application or system software, etc. The Test Plan for a project should enumerated the test beds(s) to be used.

2. What is Test Case?
A Test Case will consist of information such as requirements testing, test steps, verification steps, prerequisites, outputs, test environment, etc. A set of inputs, execution preconditions, and expected outcomes developed for a particular objective, such as to exercise a particular program path or to verify compliance with a specific requirement. Testing methodology associated with Agile Programming in which every chunk of code is covered by unit tests, which must all pass all the time, in an effort to eliminate unit-level and regression bugs during development. Practitioners of TDD write a lot of tests, i.e. an equal number of lines of test code to the size of the production code.

3. What is Test Driver?
A program or test tool used to execute a tests. Also known as a Test Harness.

4. What is Test Environment?
The hardware and software environment in which tests will be run, and any other software with which the software under test interacts when under test including stubs and test drivers.

5. What is Test First Design?
Test-first design is one of the mandatory practices of Extreme Programming (XP).It requires that programmers do not write any production code until they have first written a unit test.

6. What is Test Harness?
A program or test tool used to execute a tests. Also known as a Test Driver.

7. What is Test Plan?
A document describing the scope, approach, resources, and schedule of intended testing activities. It identifies test items, the features to be tested, the testing tasks, who will do each task, and any risks requiring contingency planning.

8. What is Test Procedure?
A document providing detailed instructions for the execution of one or more test cases.

9. What is Test Script?
Commonly used to refer to the instructions for a particular test that will be carried out by an automated test tool.

10. What is Test Specification?
A document specifying the test approach for a software feature or combination or features and the inputs, predicted results and execution conditions for the associated tests.

11. What is Test Suite?
A collection of tests used to validate the behavior of a product. The scope of a Test Suite varies from organization to organization. There may be several Test Suites for a particular product for example. In most cases however a Test Suite is a high level concept, grouping together hundreds or thousands of tests related by what they are intended to test.

12. What is Test Tools?
Computer programs used in the testing of a system, a component of the system,or its documentation.

Bug life cycle


What is defect ?
Defect indicate difference between expected and actual behavior


Life cycle:



1. New: When the bug is posted for the first time, its state will be “NEW”. This means that the bug is not yet approved.


2. Open: After a tester has posted a bug, the lead of the tester approves that the bug is genuine and he changes the state as “OPEN”.


3. Assign: Once the lead changes the state as “OPEN”, he assigns the bug to corresponding developer or developer team. The state of the bug now is changed to “ASSIGN”.


4. Test: Once the developer fixes the bug, he has to assign the bug to the testing team for next round of testing. Before he releases the software with bug fixed, he changes the state of bug to “TEST”. It specifies that the bug has been fixed and is released to testing team.


5. Deferred: The bug, changed to deferred state means the bug is expected to be fixed in next releases. The reasons for changing the bug to this state have many factors. Some of them are priority of the bug may be low, lack of time for the release or the bug may not have major effect on the software.


6. Rejected: If the developer feels that the bug is not genuine, he rejects the bug. Then the state of the bug is changed to “REJECTED”.


7. Duplicate: If the bug is repeated twice or the two bugs mention the same concept of the bug, then one bug status is changed to “DUPLICATE”.


8. Verified: Once the bug is fixed and the status is changed to “TEST”, the tester tests the bug. If the bug is not present in the software, he approves that the bug is fixed and changes the status to “VERIFIED”.


9. Reopened: If the bug still exists even after the bug is fixed by the developer, the tester changes the status to “REOPENED”. The bug traverses the life cycle once again.


10. Closed: Once the bug is fixed, it is tested by the tester. If the tester feels that the bug no longer exists in the software, he changes the status of the bug to “CLOSED”. This state means that the bug is fixed, tested and approved

What Are The Software Development Models


 This are the most used software development model 
Spiral Model
Water Fall Model
Agile Model


Spiral Model:
Spiral Model
      Spiral model proposed by Boehm in 1988 it’s mainly. Divided into 4 phase
1) Plan 
2) Design 
3) Prototype 
4) testing. 
In this model software in series of incremental realized. If we
process through iteration one or more complete version  then
engineering products are visible. It is useful when user/developer
are not cleared about the 

 solution to developed and needs evaluator approach.

Water Fall  Model:
It is also called as linear or sequential model which process through Requirement phase then Design,
Implementation, Verification, Maintenance.
This is very first software development model .It is called waterfall because it develop systematically one
phase after another in downward fashion like waterfall
1.      Requirement: In requirement we have to collect requirement from customer what exactly he want
2.      Design: If first phase get successfully approved then more elaborate technically and basic design planned 
3.      Implementation: In this phase the source code of the program is written.
4.      Verification: Testing and Integration is done in this phase to check whether its match system requirement or not
5.      Maintenance: Maintenance and management is needed to ensure that the system will continue to perform as desired.
Waterfall Model
Agile Model :

Agile model aims to develop and implement quickly in close cooperation with customer in a adaptive way, so that it is possible to react to changes set by changing business environment and at a same time maintain effectiveness and efficiency






What Is Test Plan / Test Case / Scenerio



What Is Test Plan?
Test Plan Defines purpose, scope, approach, resource, responsibility of testing activities like
What is Test Id, Introduction, Scope and limitation, Test Objective, Assumption, Risk, feature to be tested/Not to be Tested, Roles and Responsibility, Time, Test environment.

What is Test Case?
Test case is a set of input and output .Here we pass the set of input and observe the output and system behavior that its match user requirement or not.

What Test Scenario?
Test scenario is a high level definition .Here one can write one or mare test cases or in simple word set of test cases is call test Scenario.
