All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the process of compiling the cases, values of various input items are often involved, and different values have different case expectations. During testing, values of all input items of a certain function page are combined together to form a testing case containing a certain 'value combination'.
In practical applications, the inventors have found that the value combination can be achieved by the following steps. In particular, the method comprises the following steps of,
assuming that a certain function page has n input items, each input item has a plurality of forward values and a plurality of backward values, for all the input items, the following operations are performed:
first, four pools, namely a demand pool, a forward combination pool, a case step pool and a case pool, need to be defined.
1. And listing all forward values of the input items as a requirement and bringing the requirement into a requirement pool.
2. And acquiring forward values of all the input items, and taking the values of all the input items as Cartesian products to acquire all possible combination conditions to form a forward combination pool.
3. And traversing the cases in the case pool, and recording the quantity of the requirements in the existing requirement pool covered by each case.

5. And repeating the steps 3 and 4 until the number of the values in the demand pool is 0, and assuming that m forward combination cases are generated in the step.
6. And generating a negative combined case according to the positive combined case.
In order that those skilled in the art will be able to clearly understand this implementation, an example will now be described.
Assuming that a page has 5 entries I1, I2, I3, I4, I5, the following table:
TABLE 1
| Input item | Forward value of | Reverse dereferencing |
| I1 | T11、T12、T13 | F11、F12、F13 |
| I2 | T21 | |
| I3 | T31、T32 | F31 |
| I4 | T41、T42、T43 | |
| I5 | T51 | F51 |
1. And listing all forward values of the input items as a requirement and bringing the requirement into a requirement pool.

4. Selecting the combination case with the largest covering requirement quantity, taking out the combination case from the combination pool, putting the combination case into the case step pool, and taking out the requirement covered by the case from the requirement pool.
We select [ serial number 1 ] in the forward combination pool, and then there are 2-12 cases remaining in the forward combination pool, one case is added in the case step pool, and 5 requirements are reduced in the requirement pool, as shown in the following table.

TABLE 16
TABLE 17
At this time, the number of results in the requirement pool is 0, we have selected the descriptions of 3 forward combination cases at this time, step 5 ends, and step 6 begins to be executed, so as to obtain all combination results.
Although the above findings can achieve the result of value combination, the inventors found that the following technical problems still exist:
1. step 2, all the input items need to be fully combined, and the generated case combination number is the product of forward values of all the input items according to a multiplication principle; when the number of page entries is large, the product value rises exponentially, and a lot of time is consumed for both writing and generating by using a computer program.
2. Step 3 needs to count the number of coverage requirements based on step 2, and also needs to consume a lot of time when there are many cases generated in step 2.
3. Step 5 needs to repeat steps 3 and 4, and under the condition of more input items and values, step 3 needs to be executed to count the number of coverage requirements again every time of repetition, which still causes a great deal of time consumption.
4. The method has higher complexity, needs a certain algorithm and permutation and combination basis for operators, has higher difficulty in the hands, is not beneficial to case generation of a large-scale system with more input item and value combination, and if the method is realized in a computer program, the time and space complexity is exponential O (m ^ n).
In order to solve the technical problems of complex operation, long time consumption and difficulty in starting by technicians, the inventor finds that if the forward combinations can be expanded from zero forward combinations to a plurality of final forward combinations, the time and operation for obtaining the plurality of final forward combinations from all the forward combinations in a multi-screening mode due to determination of all the forward combinations can be reduced, thereby simplifying the operation process and saving the operation time.
Specifically, after each input item is obtained, the maximum number of the forward value numbers of each input item is obtained, the input items with the forward value numbers smaller than the maximum number are screened out and determined as target input items, then forward value filling operation is performed on the target input items until the forward value number of the target input items is the maximum number, combination operation is performed on the forward value numbers of the input items to obtain a plurality of forward value combination results the number of which is the same as that of the maximum number, then reverse value combination results are determined based on the plurality of forward value combination results and the reverse value of each input item, and test cases are generated according to the plurality of forward value combination results and the reverse value combination results. That is, the test case can be generated by this embodiment, and on this basis, when performing value combination operation, only the operations of screening the maximum number of forward values, performing forward value filling operation on a target input item, and performing forward value combination operation on the input item are performed, so as to obtain a plurality of forward value combination results having the same number as the maximum number, and then determining a reverse value combination result based on the plurality of forward value combination results and the reverse values of the input items, and each step is simple in operation, so that time required for generating value combination can be shortened, and efficiency is improved.
On the basis of the above content, an embodiment of the present invention provides a method for generating a test case, and with reference to fig. 1, the method may include:
and S11, acquiring each input item.
In practical application, referring to table 18, the input item includes at least one forward value, for example, input item I1 has three forward values of T11, T12, and T13, and input item I2 has T21 a forward value, and in addition, the input item may include at least one backward value, or may not include a backward value, for example, input item I1 has three values of F11, F12, and F13, but I2 does not have a backward value.

Specifically, the number of forward values of each input item is determined, and then the maximum number is selected, referring to table 18, in table 18, the maximum number of forward values is 3, that is, max is 3.
And after the maximum number is determined, screening out the input items of which the number of forward values is less than the maximum number, such as 3, and determining the input items as target input items. In the present embodiment, the target entries are I2, I3, and I5.
And S13, performing forward value filling operation on the target input items until the number of forward values of the target input items is the maximum number.
In practical application, forward value filling operation is performed on the target input items, so as to ensure that the number of forward values included in each input item is the same.
More specifically, in this embodiment, in specific implementation, the following may be implemented:
filling at least one target forward value into the target input item until the number of the forward values of the target input item is the maximum number; the target forward value comprises a last forward value in the forward values included in the target entry.
Referring to table 19, the entries with forward values less than 3 are filled, the filling entry is the last value until 3 entries are filled, and the following table is shown after filling (bold font is filled):

| Input item | Forward value of | Reverse dereferencing |

| I5 | T51、T51、T51 | F51 |
And S14, performing combination operation on the forward dereferencing of each input item to obtain a plurality of forward dereferencing combination results with the same number as the maximum number.
In practical application, forward values corresponding to the same serial number in each input item can be combined to obtain a plurality of forward value combination results.
Specifically, referring to table 19, the input item I1 has three forward values T11, T12, and T13, which correspond to sequence numbers of 1, 2, and 3, respectively, the input item I2 has three forward values T21, T21, and T21, which correspond to sequence numbers of 1, 2, and 3 … …, the input item I5 has three forward values T51, T51, and T51, which correspond to sequence numbers of 1, 2, and 3, respectively.
In this embodiment, forward values corresponding to the same serial number in each of the input entries are combined, that is, a first forward value in the input entries I1, I2, I3, I4, and I5 is combined, a second forward value in the input entries I1, I2, I3, I4, and I5 is combined, and a third forward value in the input entries I1, I2, I3, I4, and I5 is combined, so that a plurality of forward value combination results can be obtained. In this embodiment, a first forward value of the input items I1, I2, I3, I4, and I5 is combined, a second forward value of the input items I1, I2, I3, I4, and I5 is combined, and a third forward value of the input items I1, I2, I3, I4, and I5 is also referred to as a vertical alignment value, and referring to table 20, finally, 3 forward value combination results are generated, and the combination results are shown in the following table:

And S15, determining a reverse-value combination result based on the forward-value combination results and the reverse values of the input items.
In practical application, the reverse-valued combination result is obtained according to the forward-valued combination result, and specifically, referring to fig. 2, the determining process of the reverse-valued combination result may include:
and S21, selecting one forward-direction value combination result from the multiple forward-direction value combination results, and determining the forward-direction value combination result as a target forward-direction value combination result.
In practical application, one forward-direction value combination result can be randomly selected from the plurality of forward-direction value combination results, and the forward-direction value combination result is determined as a target forward-direction value combination result.
For example, in the generated forward value combination results, a combination x is selected optionally, and the value of each input item is recorded, where case T11T 21T 31T 41T 51 with sequence number 1 is selected.
And S22, acquiring the reverse value of each input item.
In this embodiment, the total reverse-value-taking number of all the entries of the function page is 5(F11, F12, F13, F31, and F51).
And S23, for each reverse value, replacing the target data in the target forward value combination result with the reverse value to obtain a reverse value combination result, wherein the target data is the forward value in the same input item with the reverse value.
Specifically, for each reverse value V of each input item, V is used to replace the forward value of the corresponding input item in x, and then 5 reverse case combinations can be generated, as shown in the following table. In addition, the bold part in table 21 is a value after replacement.

| 7 | T11 T21 F31 T41 T51 | |
| 8 | T11 T21 T31 T41 F51 |
Judging whether the expected result is reverse expectation or forward expectation according to whether the value combination of each row has reverse value, and filling the expected result of each row; in this example, the combination of values in three cases, 1, 2, and 3, does not contain the [ reverse value ], so the expected result is the [ forward expected ], and five cases, 4, 5, 6, 7, and 8 contain the [ reverse value ], so the expected result is the [ reverse expected ], as shown in the following table:
watch 24
