Functional Testing Interview Questions

FRD stands for functional Requirement Document. The first type of testing you would do when the FRD is ready and approved is STATIC TESTING. This involves studying the work documents like the Requirem...

What is FRD here ???

Smoke testing is a shallow and wide approach whereby all areas of the application without getting into too deep, is tested.

A sanity test is a narrow regression test that focuses on one or a few areas of functionality. Sanity testing is usually narrow and deep.

Smoke testing-it is a bulid verification test.
only the essential functionalities will be checked.

Sanity testing-only sanity of code will be checked.
Particular code will be checked before it actually combined to existing system.

b) Ensuring that the system is acceptable to all users

I would say all above the reasons are correct. Testing should takes place at user end(Different environment)testing should meet end user specification.

Functional testing is nothing but testing the each and every component independently is known as functional testing.

Testing each and every component of the application with all possible values is called Functional Testing

Equivalence partitioning is a technique that divides the i/p domain of a program into classes of data from which test cases can be delivered. - For each piece of the specification, generate 1 or more ...

Avoiding redundancy in testing...some of the similar kinds of tests can be combined into one test scenario and handled.

Best ways to test during time crunch:

- Adhoc testing. FSD, BRD etc are available so life is easier.
- Scenario-based testing. Pick positive, common and negative scenarios and test UI, component functionality, etc while QA proceeds through a scenario.

functional testing: testing each and ever functionality in the application whether it is working properly or not giving valid information to the implication,and invalid information to the application,functionality is a black box testing.

Functional testing is a type of black box testing that bases its test cases on the specifications of the software component under test. Functions are tested by feeding them input and examining the output, and internal program structure is rarely considered (Not like in white-box testing)

I didn't understand structural testing means, in functional testing to check the application functionality not only individual , but also different part(Combination) of the application functionality t...

Functionality testing is testing for requirements. So now tell us wouldn't you like to check if the application adheres to the requirements that client desires as they are paying for the entire project?

Hi Black box testing which is otherwise termed as Specification based technique.Hence the major job of this technique is abiding the specification made for the project.This technique is handicapped w...

For testing;
Agile require more effort for regression testing and automation testing than Waterfall.

In Agile methodology we are repeating the cycle of develop and test.We started from FRD to do coding and then testing,small builds are coded and tested again if any new modifications are needed it ca...

I'm guessing you mean backward compatibility testing?? Given multiple version releases, an application created on a new version should still work with the older versions making it backwards compatibl...

Backward testing means testing the application backward means if you find any defect while testing the application find out the route cause of that defect by checking the testcases properly written o...

Hi krishna, I m explaining it with the functionality of the OK button for login. "test case ID number" : TC1 "test case name" : Login module for OK button "test objective"...

Enables or disables the users' ability to exit a script from the tray icon menu.

Seems to me a Break-In Function refers to setting a breakpoint in a particular function using an debugger in order for the program to halt when the breakpoint is reached. 

Assume the four fields are present in the application those areuser namepassword phone numbermail idIn this Password and Mail id both are required fields o complete the registration1. Press submit b...

Along with all these tests we also have to test for the next tab. After entering first field and when we press tab to go to next field exactly where it taking the control.

Question to ask from Interviewer: Is it a geyser or a simple water heater rod? TCs for water heater rod: Acceptance Test case: Verify if the water heater heats given amount of water in specified ...

Functional test cases tests the basic functionality of the product.For water heater we can have following test cases:1. Verify if it heats the water.2. Check if it satisfied the claims mentioned in sp...

Functional test cases can be mapped with functional requirement document with the help of Requirement traceability matrix (RTM).RTM is a document which shouws the mapping of test cases against require...

If the field accepts positive numeric values
1. Test for max length
2. Test for negative value
3. Test Boundatory values
4. Test Equivalance

If alpha numeric
1. Test for max length
2. Test for special char

One other possibility not mentioned above.On international web sites the character set may very well change, e.g. English in one region, Japanese in another.Test that only valid sequences are allowed,...

Min and Max length of Password is as per the functional spec/SRS. But ideally it is 6 to 18.Testing at boundary values is called Boundary Valuec Analysis. Testing has to be done for Values at 6, 6-1, ...

The minimum and maximum length of a password is defined in the application's business requirements or technical specifications.  It is generally 6 to 12 characters in length.  To test it...
