What is COMPATIBILITY TESTING?

Testing to ensure compatibility of an application or Web site with different browsers, OSs, and hardware platforms. Compatibility testing can be performed manually or can be driven by an automated functional or regression test suite.

How to explain difference between v&v give the example

Have you ever prepared an "Egg Omelette"! I am assuming that you have prepared. So how will you prepare an "Egg Omelette"? You will try to get all the ingredients required for making an "Egg Omelette" like - eggs, oil, salt, onion, and the other ingredients if any! Then what will you do? You will "verify" the ingredients and see if they are of good enough "quality" and in proper "quantity". Won't you? Here you are doing Verification.

Now let me assume that you have prepared "Egg Omelette". Now will you directly serve it to your guests? Or you would like to "taste" it to see if it has been prepared well? A good cook will choose to taste the dish before serving it to guests. This is comparable to Validation.

Difference between Smoke testing or Sanity testing

Sanity Testing:
Sanity testing is used to test in intial check up is made on the build after recieving from developer.
Sanity Testing:When a major bug is filed in a build,developers will fix that particular bug alone and releases a new build ,testing the new build to check the particular issue is fixed and fixture has not caused any impact on other functionality,is known as "Sanity Testing"

Smoke Testing
In this we test that application is able for the further testing or not. We just check the capability of the application for testing.
We can check following things in this:
i)Build is properly installed on the system( because sometimes application crash during installation of the application).
ii)Installed application properly connected with the database and network.
iii)All the module are display and working fine.

Boundary value testing

is a technique to find whether the application is accepting the expected range of values and rejecting the values which falls out of range.
Ex. A user ID text box has to accept alphabet characters ( a-z ) with length of 4 to 10 characters.
BVA is done like this, max value:10 pass; max-1: 9 pass;
max+1=11 fail ;min=4 pass;min+1=5 pass;min-1=3 fail;
Like wise we check the corner values and come out with a conclusion whether the application is accepting correct range of values.

Difference between RTM and TRM

RTM (Requirment Tracebility Matrix): means mapping between requirements and testcases to check whether all testcases are covered or not


TRM (Test Responsibility Matrix): meanswhich type oftesting technique has to be chosen to corresponding usecase

Difference between use case and test case

USE CASE:is a functional and system requirement of how a user uses the system being designed to perform a task.it provdes a powerful communication between customer,developer and tester...


TEST CASE:test cases r written on the basis of use case documents..that describes an input action or event and expected response to determine if a feature of an application is working correctly

Relationship between SDLC or STLC

Stage 1: When Contract is signed or Organization got a project from the customer, by refering to SOW(Statement of Work) or Requirements the "UAT(User Acceptance Test) Plan is preparedand the same under goes reviews(Verification).

Stage 2. (Requirement Gathering):- Once requirement gathering or study is over the "SRS(Software Requirement Specification)" is prepared and it's reviewed(Verfication) and once SRS is finalised STP(Software Test Plan) is prepared and the same under goes reviews(Verification).

Stage 3. (High Level Design):- Taking SRS as input, HLDD (High Level Design Document) is prepared and same under goes Reviews(Verification) . Once HLDD is ready, refering the same ITP(Integration Test Plan) is prepared and the same under goes reviews(Verification).

Stage 4. (Low Level Design) :- Taking HLDD as input LLDD(Low level Design Document) is preparedand same under goes Reviews(Verification) .Once HLDD is ready, refering the same UTP(Unit Test Plan) is prepared and the same under goes reviews(Verification).

Stage 5. Coding(Impelementation):- Taking LLDD (Low level Design Document) coding will done and coding also under goes reviews(Verification).
This is all about Verification Part , Now on wards the Validation or Actual Testing starts

Stage 6. Unit Test :-Once coding of unit(s) is done , unit testing(Validation)w will be carried out by refering to the test cases (present in UTP).

Stage 7. Integration Test :- once all the units get tested, Integration testing (Validation)will be carried by refering to test cases (present in ITP).
