Professional Functional Testing Interview Questions & Answers:

1. What is the min and Max length of password?

Testing application with some boundary values

i.e

Before the value

Beyound the Value

there are three types of inputs for an module

i.e

Entering the values before the current and correct value

accurate input value

beyound the value

2. Tell me have you found any difference while testing a flash file and HTML file? If yes what are they?

Flash:

-> Extensions: .Swf or .fla
-> It's used to develop advertise ments, animations, web page components
-> Content/component is dynamic

HTML:

-> Extensions: .HTML
-> It's used to develop the web pages
-> Content/component is static
-> Flash files can be integrade into web pages

3. Tell me how many possibilities are there to test a text field? What are they?

If my understanding is right. You can test the below conditions, which are BVA.
(If assumed the max length is 10)
1. Leave the field blank.(0)-If the requirement says the field is mandatory then this test should fail. If not should allow to leave it blank.
2. Enter any text with length max-1(9)
3. Enter any text with maximum length(10)
4. Enter any text with length max+1(11)

In Most cases ECP is not defined. But if its defined for example the requirement is A-Z,a-z and 0-9 are the only valid set.
Then you can test the below conditons:
1.It should give an error when a spl character is entered.
Depending on the priority of the the requirement. You can test different conditions like.a) having a spl char at start
b) having a spl char at the end. and etc.

4. Tell me how will you check for a selected list box value using Selenium?

5. Write the Functional Test Case clearly for the water Heater?

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 specification document like: electricity consumption, works on 3-Phase or 1-Phase current, maximum capacity of water it can heat, risk factors and protection factors (from current).
3. The weight of the geyser.

6. Tell me how the Functional Test Cases could be mapped?

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 requirements. So if we want on to trace a test case to a requirement, we can see the mapping in RTM document.

7. Suppose I have three text fields, one should accept a string as input,
second text box should accept a float as input and
the third text box is for output.
the output should be an integer. what are the possible test cases we can write for the above functionality?

1.verify that the first field is accepting string.
2.verify that the first field is not accepting any thing other than a text(numbers(purely numbers with out any string data type) null characters, special characters)
3.verify that the second field is accepting float values.
4. verify that the second field is not acepting any thig other than float.
5.verify the output when the above conditions are met, o not.

8. Suppose a Page/Form has 4 Mandatory fields to be entered before you Submit.
How many no. of test cases are required to verify this?And What are they?

Well, in this case we can have the following scenarios

Five test cases:
1. Enter the data in all the mandatory fields and summit, shouldnt issue any error message
2. Enter data in any two mandatory fields and summit, should issue an error message
3. Dont enter in any of the fields should issue an error message
4. If the fields accept only number, enter numbersin the fields and submit, should not issue an error message, try to enter only in two fields should issue an error message, and enter alphabets in two fields and number in other two fields it should issue an error meaage
5. If the fields doesnt accept special characters, then enter the charatcers and submit it.

9. Explain what are the modules and sub modules manually tested in Retail banking project?

There are 3 modules in Retail banks 1. Admin, 2.Banker 3.Customer. I wanted to know, commonly what are the change requirement occurs in these modules(in a already working bank)? Also, provide few test scenarios the respective change requirement?

10. Tell me are both Bakward Testing & Regression Testing one and the same? If Not, What is the difference between them?

Back end testing means testing database. testing the inputs properly saved at back end or not.make sure whatever we input data at front end it properly saved at backend. Where as regression testing means repeatedly testing the application to make sure application should reach as per the requirement specification.
