and when the two rules have different condition items or the two rules have the same condition item and the judgment results of the condition items are different, reselecting the two rules until each two rules in the rest rules have different condition items or each two rules have the same condition item and the judgment results of the condition items are different or only one rule is left, filling the rest rules into the part corresponding to the action item in the process judgment table.
5. The method of converting a test decision list for an automotive controller into test cases of claim 1, further comprising: before the step 1, condition items, action items and rules in the initial decision table are identified.
6. The method according to claim 1, wherein in step 4, the rule can no longer be merged means that each two rules have different condition items, or each two rules have the same condition item, and the determination results of the condition items are different.
7. A system for converting a test decision list for an automotive controller into test cases, the system comprising:
a memory storing computer-executable instructions;
a processor executing computer executable instructions in the memory to perform the steps of:
step 1: extracting a rule with an action item in an initial judgment table of the automobile controller aiming at the action item;
step 2: acquiring the number of rules with the action items, comparing the number with a number threshold, and filling the rules into a part corresponding to the action items in a process judgment table or filling the combined rules into a part corresponding to the action items in the process judgment table based on a comparison result;
and step 3: repeating the step 1-2 for each action item in the initial judgment table to obtain a corresponding process judgment table;
and 4, step 4: taking the process judgment table as the initial judgment table, emptying the process judgment table, and repeatedly executing the steps 1-3 until the rules can not be combined again, so as to obtain the process judgment tables corresponding to all action items in the initial judgment table;
and 5: and taking the process judgment table generated in the step 4 as a final judgment table, and generating the test case based on the final judgment table.
8. The system for converting a test decision list for an automotive controller into test cases of claim 7, wherein the quantity threshold comprises a first quantity threshold equal to 1 and a second quantity threshold equal to 2;
and when the number is equal to the first number threshold, filling the rule into a part corresponding to the action item in the process judgment table.
9. The system according to claim 7, wherein when the number is equal to the second number threshold, the condition item of each rule is identified, and when each rule has the same condition item and only one of the condition items has different determination results, each rule is merged based on the same condition item, and the merged rule is filled into the part corresponding to the action item in the process decision table;
and when each rule has different condition items or each rule has the same condition item and the judgment results of the condition items are different, filling each rule into the part corresponding to the action item in the process judgment table.
10. The system for converting a test decision list for an automotive controller into test cases of claim 7, wherein when the number is greater than the second number threshold, performing the steps of:
step 201: two rules are selected;
step 202: identifying condition items of the two rules, merging the two rules based on the same condition item when the two rules have the same condition item and only one of the condition items has different judgment results, and filling the merged rule into a part corresponding to the action item in the process judgment table;
and when the two rules have different condition items or the two rules have the same condition item and the judgment results of the condition items are different, reselecting the two rules until each two rules in the rest rules have different condition items or each two rules have the same condition item and the judgment results of the condition items are different or only one rule is left, and filling the rest rules into the part corresponding to the action item in the process judgment table.
