Manual Testing Online Test

Adaface is developing a new database system called “Helen”. The tester at Adaface developed the following testcase for regression testing:

1. Open Helen
2. Open “Students” database
3. Enter data for “Sid”
4. Set checkpoint
5. Store “Sid” data in “Students” 
6. Restart Helen
7. Read “Sid” data from “Students”
8. Compare checkpoint with the contents

When the tester ran the testcase the first time, it worked as expected. Pick the correct statements:

A: When the test case is ran the second time, the data entry for “Sid” already exists in the database. 
B: When the test case is ran the second time, it performs exactly as it did the first time
C: The testcase is a good example for regression testing “Helen”
D: The testcase is not a good example for regression testing “Helen” since the system behaves differently when the testcase is ran the second time

Check the following decision table:

What are the expected actions for following testcases?

I: Joey's age is 22. He is a smoker residing in India

II: Jennifer's age is 62. She is a non-smoker not residing in India

A) I - Insure, 10% discount. II - Insure, no discount
B) I - Don't insure. II - Don't insure
C) I - Insure, no discount. II - Don't insure
D) I - Insure, no discount. II - Insure, 10% discount

Review the following incident report written QA team of LWB, Little White Book (an e-commerce app):

1. Place any items in the cart (Say “Nike FST Men”).
2. Place any other (different) item in the shopping cart (Say “Nike Air Max”).
3. Remove “Nike FST Men” from the shopping cart, but leave “Nike Air Max” in the cart.
4. Click on “Check out” button.
5. Expect the app to display the check out screen, instead ‘No items in the shopping cart. Click continue to go back to shopping.’ error message is shown as a popup.
6. Click “Continue”.
7. Expect the app to go to shopping screen to add/remove items from the cart. Instead the app crashes. 
8. The error in steps 5 and 7 occurred in every attempt of 5 attempts (1 2 3 4 and 6).

Which of the following information is missing from the incident report?

Review the following algorithm to calculate the final bill in a store:

Algorithm: 

1. Each purchase has three amounts - base, special and extra
2. On the base amount - If there is a discount offer going on in the store, the discount is applied 
3. There are no discounts on the special amount
4. On the extra amount - customer is offered 19% discount if accrued credits are equal to or more than 25 or 10% if the accrued credits are equal to or more than 13. If the accrued credits are lesser than 13, no discount on the extra amount is offered. In case there is a discount offer going on in the store, the discount on extra amount calculated based on credits cannot be lesser than the discount offer.

Here is the code written by the developers for this algorithm:

Here is the code the developers wrote to test the program when a customer has 13 credits and store offer is 0:

Pick the correct statements:

A: The code works correctly as expected without any defect
B: The program has unreachable code and generates faulty output when credits are ≥ 25
C: The testcase is written correctly and tests the test case as expected
D: The testcase need to be modified to account for imprecise rounding of floating numbers. Ex: (price == 12900.00) can be replaced with ((price - 12900.00) < 0.01)
E: The testcase need to be modified to account for imprecise rounding of floating numbers. Ex: (price == 12900.00) can be replaced with (abs(price - 12900.00) < 0.01)

Adaface testing team does data flow analysis on the programs written by the development team. The testing team follows the following marking schema for the variables in a program:

Variables of interest in a code (possible states):
- d: variable is assigned a value
- r: value of variable is read
- u: variable has no defined value

Variables of interest in a code (marking schema):
- ur: undefined value of a variable is read on a program path r
- du: variable is assigned a value that becomes undefined/ invalid without having been used in the meantime
- dd: variable receives a value for the second time and the first value had not been used

Review the following program and pick the correct marking of the variables:
