4.2.1 Equivalence Partitioning

Question 1

Equivalence Partitioning (EP) divides data into “ “ (equivalence partitions) based on the expectation that a… of a g… are to be “ “ in the same way by the t…

Answer 1

partitions
all the elements
given partition
processed
test object.

Question 2

Technique theory is that if a … that tests one value from an … detects a defect … should be detected by … that test any …
from the …

So, one test for … is “ “.

Answer 2

test case
equivalence partition
this defect
test cases
other value
same partition.

each partition
sufficient.

Question 3

Equivalence partitions can be identified for any data element related to the test object including:
- in…
- ou…
- conf…
- inter…
- time-r…
- interf…

Answer 3

• inputs
• outputs
• configuration items
• internal values
• related values
• interface parameters

Question 4

The partitions may be:
- “c…“ or “ “
- “o…“ or “ “
- “f…“ or “ “

The partitions must not “ “ and must be n…

Answer 4

• continuous
  discrete
• ordered
  unordered
• finite
  infinite

overlap
non-empty sets.

Question 5

For simple test items, EP can be easy, but in practice understanding how the t… will treat d… is often “ “.

Partitioning should be …

Answer 5

test object
different values
complicated

done with care.

Question 6

A partitioning containing valid values is called …

A partitioning containing invalid values is called …

Answer 6

valid partitioning.

an invalid partitioning.

Question 7

Valid values may be interpreted as those that should be “ “ by the … or as those for which the “ “ defined their “ “.

Answer 7

processed
test object
specification
processing

Question 8

Invalid values may be interpreted as those that should be i… by the … or as those for which … is defined in the t…

Answer 8

ignored or rejected
test object
no processing
test object specification.

Question 9

In EP, the coverage items are the e…

Answer 9

equivalence partitions.

Question 10

To achieve 100% coverage with this test technique, test cases must exercise a… by covering each “ “ at least “ “.

Answer 10

all identified partitions (including invalid partitions)
partition
once

Question 11

Coverage is measured as the number of partitions exercised by at least one test case “ “ by the … of … and is expressed as a “ “.

Answer 11

divided
total number
identified partitions
percentage

Question 12

Many test items include m… (test items with more than one input parameter) which means that a … will cover “ “ from different sets of “ “.

Answer 12

multiple sets of partitions

test case
partitions
partitions

Question 13

The simplest coverage criterion is the case of multiple sets of partitions called …

Answer 13

Each Choice coverage.

Question 14

Each Choice coverage requires test cases to exercise each partition from each set o… at l…

Each Choice coverage doesn’t take into account c…

Answer 14

of partitions
least once.

combinations of partitions.
