Second, determine the question
1 , the effective defect equivalence classes may capture program, invalid equivalence class can not capture defects. ( × )
2 , the program asks if the value is a finite value interval, and can be divided into an invalid equivalence class (outside the range) of a valid equivalence class (range). ( × )
3 , using the boundary value test method, only two boundary values takes to complete boundary testing. ( × )
4 , FIG cause considered various combinations between program input and output. ( √ )
5 , decision table is a cause and effect diagram method evolved. ( × )

B , or
C , required
D , the only
2 , the following options, which one is bound by the relationship between cause and effect diagram output. ( C)
A , different
B , or
C , forced
D , requirements
3 , the following options, which one is not the key factor orthogonal experiment method. ( D )
A , index
B , Factor
C , Factor state
D , orthogonal
Fourth, the short answer questions
1 , please describe briefly the principle of equivalence partitioning method.
( 1 ) If the program requires the input value is a value interval, the input data may be divided into an effective equivalence class and two invalid equivalence class equivalence class for the specified effective value interval, two invalidation price categories are equal to both sides of a finite interval
( 2 cases) If a program requires the input value is a "must be true", the input data may be divided into a valid and an invalid equivalence class equivalence class
( 3 ) If the program requires the input data is a set of possible values; or require input values must meet a certain condition, you can input data into a valid and an invalid equivalence class equivalence class
( 4 ) if in one equivalence class, each of the input data processing mode in the program is not the same, the equivalence class should be divided into smaller equivalence classes, and to establish equivalence table
2, please describe briefly the conditions of the merger rules decision table entry.
If the operation condition items and a key generated by another condition is the same, and even a value for each row corresponds to only one condition items are different, it can be combined.
3, please briefly orthogonal design test design steps.
- Extraction factor, factor state table configured
- Weighting filter, simplifying factor state table
- Construction of orthogonal design test cases
