20.red,green,yellow.........

These are three bulbs. When a
person works for 4hours the red bulb glows, when he works for 6 hours the green
bulb glows and when he works for 8 hours the yellow bulb glows.





What test cases could you write for the above
scenario?

[Spoorthi]

Tell me something about your project.

describe abt ur project wat u've mentioned in ur resume







What is Integration testing?

Integration perfom by the developer.We integrate diffrent units
& then functionality is tested.This type of testing is especially
relevent to client/server and distributed systems.

[Spoorthi]

What is Regression Testing?

Regresion testing:-Regresion means small change,in regresion
testing the application is tested for the changes made.changes can be
testing the fixed bug.Testing the application the addition or
modification of any features in application.





What is the difference between Retesting and regression
testing?

Ans:-re testing after fixes or modifications of the s\w or its
environament.it can be difficult to determine how much re testing
needed,especially near the end of development cycle.Automated testing
tools can be especially useful for this type of testing.Resting the
application once the bug is fixed so that it doen't lead to other bug.



Regresion testing:-Regresion means small change,in regresion testing
the application is tested for the changes made.changes can be testing
the fixed bug.Testing the application the addition or modification of
any features in application.

7.What is the difference between system testing and integration testing?



Ans:-System testing is black box type testing that is based on overall
requirements specifications;covers all combined parts of a system,like
s\w,h\w,doccument,&tested for the major functionality.



Integration perfom by the developer.We integrate diffrent units &
then functionality is tested.This type of testing is especially
relevent to client/server and distributed systems.





8.What is the difference between Black box testing and White Box testing?



Ans:-Black box testing not based on knowledge of internal design or code.Tests are based on requirements and functionality.



White box testing based on knowledge of the internal logic of an
application's code.Tests are based on coverage of code
statements,branches,paths,conditions.

What is Unit Testing?


Unit Testing is a testing technique in which smaller units of code are tested to validate whether they are in compliance with the requirements provided. The successful code units are then shipped for integration with other code modules. Unit Testing is generally performed by the individualswriting the code.

[satyasri2test]

What is Integration Testing?


Integration testing is a technique of integrating the code units from differentfeatures to produce a single moduleand then testing theintegrated moduletocheck whether there are any inconsistencies existamong the codeunits due to the data and/or the control flows.

10.Is functional testing a type of Black box or White box
testing?

Functional testing is a king of blackbox testing. In both cases we don't bother how the program flow is going. We observe only whether the desired functionality is present or not and whether the outout is predictable or not.

What is Load testing and Stress testing?


Since I don't have a live experience with either, I am redirecting the question to the following URL

What is smoke testing?


The initial testing effort that is performed at the earliest stages of product development to determine if theproduct is performing as expected. This testing is also known as Sanity Testing.Edited by: satyasri2test

[satyasri2test]

What is Verification and Validation?


Verification: It is a process of reviewing and evaluating the documents, designs, plans and code through inspection meetings, code walkthroughs, checklists, etc.


Validation: It is a testing method in which the product is tested to see if itis developed according to the documented requirements and performs the functionality as intended. This usually takes place after Verification is completed.

What is smoke testing?


The initial testing effort that is performed at the earliest stages of product development to determine if theproduct is performing as expected. This testing is also known as Sanity Testing.

Your definition of smoke testing is correct. But, as per my understanding, it can't be called as Sanity testing. We can perform Santiy Testing in any phase of the testing. And especially after every major patching is been done.

If we take banking system as an example, checking whether deposit and withdrawel is working fine or not is sanity testing. And you will check this after any big patch has went in and verify nothing major has broken which is very serious issue. It can be done at any phase of testing. Also in this case, we will enter all the valid data in the fields. But, in smoke testing it need not be the case.

Thanks,
Krishna

Hi Krishna,


Thanks for correcting me with an apt example.
