Term
|
Definition
| specific data set for testing a program |
|
|
Term
| Consider a program that calculates the distance of a prowling lion from the center of Lynchburg, VA and determines whether or not the lion is prowling outside of Lynchburg's periphery. If d is the lion's distance from the town's center in miles, what is a test case representing a lion 45 miles from the town's center? |

|
Term
| How is static testing different from dynamic testing? (besides the obvious) |
|
Definition
| it is difficult and expensive, and does not guarantee that your program will be correct. However, it can work well for small programs |

Term
| unit testing procedures process |
|
Definition
| unit test's driver provides input data under the test, and reports the test result. Stubs emulate the units that the UUT calls. |
|
|
Term
|
Definition
| Test cases are generated within the input domain's extremes. Focuses on testing data on boundaries, and on each side of the boundaries |
|
|
Term
Consider a program that finds nay-saying lions' distances from the center of Lynchburg, VA.
Lynchburg's periphery is approximately 25 miles from the town's center. If we assume that the lions must always remain within 3 miles of the periphery, and must not stray from city limits, a lion less than 47 miles or more than 50 miles from the town's center is not prowling the periphery.
If we test lions with distances of 46, 48, 49, and 51 miles from the town's center, what is this an example of? |

Term
Consider a program that finds nay-saying lions' distances from the center of Lynchburg, VA.
Lynchburg's periphery is approximately 25 miles from the town's center. If we assume that the lions must always remain within 3 miles of the periphery, and must not stray from city limits, a lion less than 47 miles or more than 50 miles from the town's center is not prowling the periphery.
We divide the data into the following partitions:
1. Invalid: <0 miles (Lions with a negative distance)
2. Invalid: >0 & < 47 miles (Lions inside Lynchburg, but not on the periphery)
3. Valid: >47 & <50 miles (Lions prowling the periphery)
4. Invalid: >50 & <12,450 miles (Lions outside city limits)
5. Invalid: >12,450 (Maximum possible distance on Earth's surface)
If we test distances of -10, 10, 49, 60, and 13,000, what is this an example of? |

Term
| equivalence partitioning testing |
|
Definition
| black-box technique that divides a software unit's input data into equivalent data partitions, then derives test cases from those partitions |
|
|
Term
| How is equivalence partitioning testing different from boundary test? |
|
Definition
| It does not focus specifically on boundaries, it is applicable to a wider range of data, you can use it when testing each possible value is too time-consuming |
|
|
Term
|
Definition
| combinatorial technique that involves testing every pair of software input parameters |
|
|
Term
Consider a program that takes for input parameters, l, i, o, and n, representing the status of four different lions. Each parameter can have one of two values: 1 (prowling the periphery) or 0 (not prowling the periphery).
In this example, there will be 24 pairs (l0, i0), ..., (o1, n1).
A test case (l1, i1, o0, n0) captures six of these pairs.
