A test models is used to describe the sequence of activities that make a Systems Development Life Cycle (SDLC). SDLC is used to describe activities of both development and maintenance work in Software Testing. Software testers can use various test models such as waterfall, iterative and agile styles while performing software testing. A brief description of various test modals is as follows:
A. Waterfall style modal Testing
The Waterfall Model approach is most basic life cycle model and is divided into following phases:
- Requirement Gathering & Analysis phase
- Software Design
- Implementation and Testing
- Maintenance
Software testing using waterfall style is a linear process like software development using the waterfall model. Waterfall testing is occasionally appropriate for situations where it is reasonable to hope that software would work, for example applying a patch to a production application.
B. Iterative style modal Testing
Iterative testing is similar to iterative development in the way that many of the test iterations happen to coincide with development releases. Testing iterations differ from development iterations in that there can be iterations prior to the first software build, and there can be multiple test iterations during a single software build. Due to many variants, Iterative software testing is extremely common in software testing companies. Iterative testing generally works well on following projects:
- where software is being developed in pre-planned, predictable increments
- where the software is being developed and released in such rapid or unpredictable cycles that it is counter productive for testers to plan around scheduled releases.
C. Agile style modal Testing
In QA testing companies, Agile style testing more or less eliminates the element of pre-determined flow from the test cycle. For example, while analyzing the results of a test, the tester may realize that test was flawed and move directly back to planning and designing tests. In a waterfall or iterative flow, that test redesign would wait until after the current results were reported and preparations were being made for the next test iteration. For example, within an iterative test approach, a tester could be encouraged to enter a period of agile testing side-by-side with a developer, while tracking down and resolving defects in a particular feature.

How software testing differ from program testing?
A test strategy is a framework that defines the testing methodology of the software development cycle. This includes the testing objective, approaches of testing new functions, types of testing to be performed, total time and resources essential for the project, and the testing environment.In any software testing company, the test strategy describes the test level to be achieved at different levels of testing i.e. unit testing, integration testing, and system testing. For every stage of development design, a corresponding test strategy should be generated to test the new feature sets.Software Testing Technique is nothing but required testing approach to be followed during testing.Testing techniques are as follows:-Static TestingWhite Box TestingBlack Box TestingGrey Box TestingAs software testing is involved in every stage of software life cycle. But, the testing performed at each level of software development is different and has different goals. They can be defined as:Static Testing: Testing of an application without execution on the computer or without executing them through values.White Box Testing: Testing is done on code.Black Box Testing: Testing is done to check the behavior of the application according to customer's requirements.Grey Box Testing: Combination of Black box and white box is called Grey box testing.
Is there really career in software testing?
Yes there is. In a world where a huge amount of software is being created, there is a big need for people to test it. So software testing is an area where is there is a lot of employment that can be a career for people.
How the wrong software process model will affect the software failure?
When you create a software you create a model or psuedocode then a flowchart for the preocess which can be called as Process Model then execution of the Software. If you have made the model correclty minimal issue wil be found during beta testing and perhaps common issue and every problem are possible to fix since you know where in the process model causes the problem. Process model can really affect the software if we did not implement and go throurh a series of testing.
What are the key differences between validation testing goals and acceptance testing goals?
In validation testing, the test team seeks to ensure that each software function or performance characteristic conforms to its specification. In acceptance testing, the test team needs to ensure that the software works correctly for the intended user in his or her normal work environment.
Smoke testing vs sanity testing?
Smoke testing will be conducted to ensure whether the most crucial functions of a software work, but not bothering with finer details. A Sanity test is used to determine a small section of the application is still working after a minor change. Smoke Testing: Smoke testing is nothing but to test the functionality of the software once build is done. Sanity testing: Sanity testing is nothing but to test the existing behaviour of an application, environment check up before starts execution.
Who offers software testing certifications?
ASTQB (American Software Testing Qualification Board) offers a test that can qualify someone to test software. There is also a software testing qualification called the ISQTB.
Software testing differs from software quality assurance?
Absolutely both are different platforms. Software Testing is the process to test the software/application fix without any bugs. Software Quality assurance is all about the delivering the right product to the end user.
Training in software testing?
Software testing training is a part of IT training. There are two way to test a software:automatic testingmanual testingThere are various methodologies use to test a software - white box testing, Black box testing, grey box testing.
What is document version in software testing?
Software testing is a cyclical process in which you: plan a test execute it identify bugs fix them test again During this process is you change the application or software you update the testing plan. This you have versions for the testing plan so that you can see what did the previous test check.
What is the structure of a software test plan?
The structure of a software test plan : The testing process requirement traceability tested items testing schedule test recording procedures hardware and software requirements constraints Mahda Noura
What is difference between sdlc and stlc in software testing?
Software Development Life Cycle involves the complete Verification and Validation of a Process or a Project. Whereas Software Testing Life Cycle involves only Validation. Software Development Life Cycle involves business requirement specifications,Analysis,Design,Software requirement specifications,Development Process(Coding and Application development),Testing Process(Preparation of Test Plan,Preparation of Test cases,Testing,Bug reporting,Test Logs & Test Reports),Implementation and Maintainence . Whereas Software Testing Life Cycle involves Preparation of Test Plan,Preparation of Test cases,Testing,Bug reporting,Test Logs & Test Reports.
What is AUT in software testing?
Application Under Test
Can you show some examples of paper presentation on software testing and software testing tools?
There are many white papers available on software testing. Some examples include approaches on test planning, increasing test team motivation and evaluating software testing tools. These particular white papers can be found as www.SoftwareTesting.net
Which software testing used for test the internal logic?
White box testing or glass box testing.
What is called unit testing in software engineering?
Unit testing is to test all the possible logic paths within a software function.
What is mean by Manual testing in software testing?
That part of software testing that requires operator input, analysis, or evaluation. Manual testing requires a tester to perform manual test operations on the test software without the help of Test automation. In other words manual testing is the one in which a person has do it himself / personally check whether everything is right or not with certain inputs to machine
W model and v model in software testing and quality assurance?
In software just tested quality assurance - get out of here.
