[@arunasavyasachi5617]

Thank you so much for explaining the istqb topics. It's really helpful in preparing for ISTQB exam

[@rplanting24]

Hello sir, thanks for your efforts in training so many students like me. Can you please explain the below decision table question? 1. A company's employees are paid bonuses if they work more than a year in the company and achieve a target which is individually agreed before. These facts can be shown in a decision table below: Test id T1 T2 T3 T4 Condition 1 Employment for more than Yes No No Yes 1 year? Condition 2 Agreed target? No No Yes Yes Condition 3 Achieved target? No No Yes Yes Action Bonus Payment No No No Yes Which of the following test cases represents a situation that can happen in real life, and is missing in the above decision table? a) Condition1 = NO, Condition2 = YES, Condition3 = NO, Action= NO b) Condition1 = YES, Condition2 = YES, Condition3 = NO, Action= YES c) Condition1 = NO, Condition2 = NO, Condition3 = YES, Action= NO d) Condition1 = YES, Condition2 = NO, Condition3 = YES, Action= NO

[@abhishekkumar7823]

I think answer is B.

[@tatianasergeeva8462]

@@abhishekkumar7823 I believe B is incorrect because a target isn't achieved, so bonus isn't paid after all due to the company's policy. It's rather A which looks much more logical and possible.

[@abhishekkumar7823]

@@tatianasergeeva8462 I got you, you're right.

[@100janyam]

looks like b is the only wrong answer, and all others are possible

[@abhijitpatange68]

Neeraj thanks for helping us to prepare for istqb, I am not clear with second example @06:09 of video since class A has age lesser than 21 years but the option fall in 23 years which is incorrect.

[@TMSQUARETECH]

Hi Abhijit, If you get your query right here is the response. In Rule 1 the conditions given are not met by any options below. Whereas, in option 2 we find the age group is between 21-29, Insurance class cab be either A or B premium is 90 and excess amount is 2500. Thus option A is the right answer. I hope this clears your doubt. Feel free to let me know in more details if required.

[@abhijitpatange68]

Thanks Neeraj now I got it, was confused with Rules and options.

[@owadiary]

just wanna say thank you for uploading all these materials. really helping me studying for final :D

[@TMSQUARETECH]

You’re always welcome.

[@owadiary]

Update: I got an A for this subject 😁

[@TMSQUARETECH]

@@owadiaryCongratulations on the achievement. All the best for your future endeavors.

[@amudhagunasekar8372]

I didn't understand the first problem? Will you able to give more explanation???

[@SalmanShaikh-eh8py]

I am not clear with first example regarding Citibank and Upgrade. Why it is not Option A rather than D ?

[@TMSQUARETECH]

Hi Salman, If you see there, in the first scenario it is mentioned as citibank card member and holding a silver room, now these two conditions are fulfilled by Rule 1. The action for rule 1 is to offer upgrade to gold luxury whereas option A says don't offer any upgrade. Moreover, scenario B say Non Citibank Member with platinum room which is Rule 4 and the action is Don't offer any upgrade in this case. Thus the final answer is D. Hope that goes in line with your understanding.

[@wanderingbob]

You need to consider members A & B in your answer. I think I see your logic, as you are only considering member B as the question looks like it is only addressing B...

[@erikwilliams1562]

I was really lost too. There was no actual question so I had no idea what I was looking at or supposed to do

[@MW2proification]

How exactly can you turn a pseudocode into a combination based table, especially for when it comes to answering a question for an exam with limited time window?

[@TMSQUARETECH]

It seems we are trying to club two different techniques which is not included in the syllabus as well as not possible in reality. In case you are considering IF as a criteria to create a table then there will be just 2 test TRUE or FALSE

[@MW2proification]

@@TMSQUARETECH thanks, I guess I was trying to get across how many test cases in a table, it is from one of the sample exam questions on the istqb site. I just don’t want to be caught off guard by any out of the ordinary questions when i study for the exam on the syllabus and your helpful videos relentlessly.

[@Localplacesfromlocalpeople]

Do we get questions on state transition testing and decision table tasting tech in exams?

[@TMSQUARETECH]

Yes for sure!!

[@dimplesingla4220]

Hi Neeraj, Can you please help me below question. You have been given the following conditions and results from those condition combinations. Given this information, using the decision table technique, what is the minimum number of test cases you would need to test these conditions? Conditions: Valid cash Valid credit card Valid debit card Valid pin Bank accepts Valid Selection Item in Stock Results: Reject Cash Reject Card Error Message Return Cash Refund Card Sell Item a. 7 b. 13 c. 15 d. 18

[@TMSQUARETECH]

I can't see the table here so I may not be able to answer this question

[@eveakospokua]

Can somebody help with this one: Consider the following decision table for the portion of an online airline reservation system that allows frequent flyers to redeem points for reward travel: * Suppose that there are two equivalence partitions fo the condition where Account/password okay is not true, one where the account is invalid and another where the account is valid but the password is invalid. Suppose that there is only one equivalence partition corresponding to the condition where Account/password okay is true, where both the account and password are valid. If you want to design tests to cover the equivalence partitions for Account/password okay and also for this portion of the decision table, what is the minimum number of tests required? b) 3 c) 4 a) 2 d) 9 ?

[@eveakospokua]

It says the answer is c - 4. But I am confused about why they have 'Account/password okay ' combined. I think they should be separated. Condition 1 - Account Okay; Condition 2: Password okay, as either of them could be false or true. If both are true and the other condition (Sufficient points) is true, then the action should be Y and Y.

[@yashdeshpande8488]

They are separate, they just said it to confuse you. Make a table having two rows Account and Password and according to the conditions give fill the columns. As the first condition says Invalid account/password that means both are False , second condition says Account is invalid so it means Account is False and password is True(Valdi- which is not given but you have to insert it by understanding it) and third says Account is valid but Password is invalid so it means that Account will have True and Password will have False and finally Both Account/Password are Valid so that's True for both. So your table will look something like this. ACC. F F T T PASS F T F T Since you have to check 4 times with 4 different scenarios so 4 test case. Hence the option C:4. P.S. Correct me if I'm wrong.

[@tatianasergeeva8462]

Couldn't it be rather smth like this for the complete test set? ACC. Y Y Y N PASS Y N Y x PTS Y x N x ____________________ HIST Y N Y N RWD Y N N N * where x = doesn't matter Also 4 tests in total, combining all the equivalent conditions and covering all the possible outcomes.

[@yinmyoesint3973]

For the last example , how many testcases we will get? Sir

[@TMSQUARETECH]

4

[@mesut993]

thank you your detailed explanation.

[@TMSQUARETECH]

You are welcome!

[@milindshirsat525]

very useful information , thank you sir !

[@TMSQUARETECH]

Glad it was helpful!

[@yagneshapandya8540]

Your material of videos is very helpful sir, but only one thing just you write greater than sign (>) wrong, in all tables "

[@TMSQUARETECH]

No offence But just to clarify How would you read this expression x >= 9 and 9

[@sandeepsuresh4506]

Thank you for your detailed explanation. Could you please help me to solve this question ?

[@hossamebrahim3681]

Answer C 4 test cases

[@heshammostafa6770]

I didnt understand the answer of the last question,Is it A because A is the closest one to the right answer ??

[@TMSQUARETECH]

Yea if you take each options and apply on the table only Option A matches the informations provided. All other options have anomalies with respect to data. Pls try this and it will give you confirmation on right answer

[@MrTVx99]

Wow this is the easiest topic for me so far. I was struggling with definitions in first 3 chapters but seeing easy questions makes me happy

[@TMSQUARETECH]

Very Glad, that content was helpful and supporting. In case you find challenging any definitions please refer my other channel which is all about glossary - kzbin.info
