Why are you not considering a TC for time before 9am on week day for staff ? If time between 0:00 and 8:59am is another partition

@stchannel1350 12 дней назад

ABC booking "staff weekday (any) 4am --- here it's a invalid partition. but under coverage

@melmelange1036 Месяц назад

Why don't you test if the the ground flour don't have a garden? There is nowhere said that the ground flour should have a garden. So for me there should be a fifth test with ground flour -> no garden.

@upekshasandamini7082 20 дней назад

I also considered another class for ground floor without a garden

@7Mushrooms7 13 дней назад

I'm confused too and answered 5 at first. In the solution it says 4.

@bisomenike9769 9 дней назад

yes, it should be there

@vaxutucuna 8 дней назад

@@bisomenike9769 it shouldn't be there, because according to the syllabus, in case of multiple sets of partitions we are using EACH CHOICE coverage. Eeach choice coverage requires test cases to execute each partition from each set of partitions at least once. Meaning that we tested NO GARDEN partition with first and second + floor test cases. so we don't need to test it with ground floor as well. remember this is to cover all values of the fields, not all combinations.

@3D0OM 2 месяца назад

for the second question you can just assume one condition is false and other being true for all minimum scenarios in an easier to understand way tc 1 - all scenarios true flight can be booked tc 2 - staff is false - flight cant be booked tc 3 - weekday is false - flight cant be booked tc4 - times are false - flight cant be booked

@mathewgeorge1247 3 месяца назад

For the Garden and Floor example, can't the answer be 6? What if there is an option to go for a ground floor apartment that has no Garden? The question only says that Garden is not possible for 1st and higher floors. It's doesn't say that all ground floor apartments should have a garden.

@Cullenium 3 месяца назад

I had similar reasoning, except I thought it was 5. Ground floor could have no garden, small, or large. First floor no garden. Second or higher floor no garden.

@mathewgeorge1247 3 месяца назад

True, 5. Not 6. Agree

@TMSQUARETECH 3 месяца назад

Okay. See the main context is are they asking for minimum or maximum. In case sof Minimum we test what is possible as per the scenario and another thing is each item to be tested at least what your saying is Maximum where I am trying the floor with each combination of garden type. So, when it comes to combinations we can try other impossible scenarios.

@iwGwendolyn 3 месяца назад

@AlexandruTanase11 3 месяца назад

@@TMSQUARETECH but do we get 100% coverage if we skip the ground/no garden option? On floor 1+ the option doesn't exist by implementation but it does for the ground floor

@Chantillian Месяц назад

So we just came from a tutorial where less than 1 (invalid), 1-15 (valid), and greater or equal 16 (invalid) are three partitions. Less than 1 isn't in the same partition as greater or equal to 16. So isn't it the same for 00:00-08:59 (can not book), 09:00-17:00 (can book), 17:01-23:59 (can not book) ? But there's no test case here in the range 00:00-08:00 (weekdays).

@upekshasandamini7082 20 дней назад

I got the same concern. I selected the answer as C, which includes 5 classes..

@vaxutucuna 8 дней назад

The flight ticket one confuses me. According to video we are making 4 test cases: STAFF / WEEKDAY / 9:00 - 17:00 STAFF / WEEKDAY / 17:01 - 23:59 STAFF / WEEDEND / 9:00 - 17:00 NON-STAFF / ANY / ANY But we are not testing 00:00 - 8:59 Anywhere. So I think there should be a 5th test case STAFF / WEEKDAY / 00:00 - 8:59. Am I mistaken? Please explain

@vaxutucuna 8 дней назад

OR alternatively, The test cases should be: STAFF / WEEKDAY / 9:00 - 17:00 STAFF / WEEKDAY / 17:01 - 23:59 STAFF / WEEDEND / 00:00 - 8:59* NON-STAFF / ANY / ANY in which case the answer "4 test cases" would make sense

Can you explain ? ISTQB 4.0 Sample Exam set C (#20 and #21 Questions)

@user-tf2vy9ek6x 3 месяца назад

For the flight booking application, I was coming up with the 5 test cases. Test 1 is valid because the time is between the definite range and test 2 is not because the mentioned time ' 7 PM' is after the specified timeline. I was wondering why did not we count an invalid test case of having booking time before 9 AM on the weekend? Can you please elaborate a bit here ? Thank you

@phoebebuffay5656 2 месяца назад

i suppose it's because we can't book on weekend at all, doesn't matter what time is. so the test case is checking in general the ability to book by staff the tickets in the working hours. and as there are no working hours on weekend, so there is no need in additional test case

@Sotyka94 2 месяца назад

The syllabus say that you can ignore combinations, and only have to test each options at least once. So for the second example, why not 3 test case? Tc1: staff, weekday, working hours. Tc2: staff, weekend, non working hours Tc3: non staff ?

@DiegoFernando-qw6lc 2 месяца назад

I solved the problem in the same way. I got frustrated. But I think the key is that only staff can book a fly. So in theory the system will not allow you to enter the rest of the information if you are not a staff member. It's the only logic that I found.

@balajiraod9877 2 месяца назад

Why Ground floor with No garden is not considered?

@sanketpatil7147 2 месяца назад

we need to find out "minimum" number of TCs

@naailahhassinabanunowrungn1851 Месяц назад

Even if the question says minimum number of test cases, shouldn't EP cater for the invalid cases too? Cause Equivalence Partitioning is also about valid/invalid partitions?

@7Mushrooms7 13 дней назад

I agree and that's what I thought at first to answer the question but I think they only take into account valid combinations because they say straight away that it's impossible to combine first or second floor with a garden. Therefor they're assuming that it's not possible to test invalid combinations. But he's I'd have tested too if that impossibility is true.

Is TEST 4 the same I do NON Staff - M/F - 9/5, correct?

@TMSQUARETECH 3 месяца назад

Yes

@tahakhan62 3 месяца назад
