Embodiment
Embodiments of the invention are described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning to end
Same or similar label represents same or similar element or the element with same or like function.Below with reference to attached
The embodiment of figure description is exemplary, it is intended to for explaining the present invention, and is not considered as limiting the invention.
Below with reference to the accompanying drawings describe the generation method of automatic test case in the automobile controller of the embodiment of the present invention and be
System.
Fig. 1 is the flow of the generation method of automatic test case in automobile controller according to an embodiment of the invention
Figure.
As shown in figure 1, the generation method of automatic test case comprises the following steps in the automobile controller：
S101, generate initial test case.
Wherein, initial test case includes assignment name corresponding to signal name and signal name.
Specifically, when writing initial test case, can directly using readability spoken and written languages writing signal name and its
Assignment name, ways of writing can be " signal names=assignment name ", such as gas pedal=step on suddenly, key=ON shelves, engine failure
=3 grades of failures, battery tension=12V etc., writing is simple and convenient, and readability.
S102, obtain the Substitution Rules sent between signal and measurement signal.
In an embodiment of the present invention, transmission signal refers to all signals for including signal name in initial test case,
Measurement signal refers to all signals for including signal name in the test case available for new software functional test, wherein, hair
Corresponding relation between the number of delivering letters and measurement signal be present.Substitution Rules include by signal name, assignment name, Map Names, Map Names it
Between the logical relation that is formed of correlation and evaluation mapping name.The Substitution Rules can be represented with form, such as can use table 1
Represent：
Table 1
As shown in table 1, the used spoken and written languages for expression signal name in the entitled initial test case of signal, i.e. table
Chinese name 1 in 1, can be gas pedal, key, engine failure etc..Some entitled signal specific name of assignment is all
Involved assignment name, assignment name can have any number of, i.e., assignment 1, assignment 2, assignment 3 in table 1 in initial test case
Three kinds of assignment names, can be oil step on suddenly, ON shelves, 3 grades of failures.Map Names must be the recognizable title of test software, and one is believed
Number name can correspond to multiple Map Names, there is 4 Map Names, i.e. Map Names 1, Map Names 2, Map Names 3, Map Names 4 in table 1.Reflect
The correlation penetrated between name have or and with two kinds expression, its effect is that multiple Map Names can be made to be provided simultaneously with some signal name
Effect, or with the synergy of multiple Map Names come the effect of equivalent signal name.Evaluation mapping name must be initial testing
The recognizable title of use-case, can be specific numerical value, or relational expression or certain curve, possibly even
Some complicated function, i.e., the mapping value 1 that is shown in table 1, mapping value 2 ..., mapping value 7.
S103, operation is replaced to initial test case according to Substitution Rules to generate final test case.
Wherein, initial test case is corresponding with the title and/or sequence number of final test case.
Specifically, as shown in Fig. 2 being replaced operation to initial test case according to Substitution Rules to generate final survey
Example on probation comprises the following steps：
S201, signal name to be replaced is determined, and signal name to be replaced is indexed in initial test case.
Wherein, signal name to be replaced can be the Chinese name 1 in table 1.
S202, judges whether the number of Map Names corresponding to signal name to be replaced is equal to 1.
S203, if so, signal name to be replaced in initial test case then is replaced with into Map Names, and assignment name is replaced with
Corresponding evaluation mapping name, to generate final test case.
Specifically, if the number in Map Names is equal to 1, as shown in table 1, there was only Map Names 1 in Map Names, then can be by
Literary fame 1 replaces with Map Names 1, and assignment name is replaced with into corresponding evaluation mapping name, i.e. " Chinese name 1=assignment 1, Chinese name 1=
Assignment 2, Chinese name 1=assignment 3 " will replace with：Map Names 1=mapping values 1, Map Names 1=mapping values 2, Map Names 1=mappings
Value 3.Terminate after the completion of replacement, the final test case of generation includes Map Names and its corresponding mapping assignment after replacing
Name.
S204, if it is not, then judging the correlation between multiple Map Names corresponding to signal name to be replaced.
S205, if it is multiple mapping it is entitled and relation, each signal name to be replaced in initial test case is replaced with
The set of all Map Names, and assignment name is replaced with into corresponding evaluation mapping name, to generate final test case.
For example, as shown in table 1, if the correlation between multiple Map Names is and the general of Chinese name 1=assignment 1
Replace with：Map Names 1=mapping values 1, Map Names 2=mapping values 4, Map Names 3=mapping values 6, Map Names 4=mapping values 7 this 4
Individual set；Chinese name 1=assignment 2 will replace with：Map Names 1=mapping values 2, Map Names 2=mapping values 5, Map Names 3=are assigned
Value 2, Map Names 4=assignment 2 this 4 set；Chinese name 1=assignment 3 will replace with, Map Names 1=mapping values 3, Map Names 2
=assignment 3, Map Names 3=assignment 3, Map Names 4=assignment 3 this 4 set.
S206, if multiple mappings it is entitled or relation, generate and spread out with Map Names quantity identical initial test cases
Raw file, and the signal name to be replaced in derivative file is replaced with into Map Names, and assignment name is replaced with into corresponding assignment and reflected
Name is penetrated, to obtain final test case.
For example, as shown in table 1, if the correlation between multiple Map Names be or, if can generate following 4 respectively
Derivative test case：
First derivative use-case, Chinese name 1=assignment 1 replace with：Map Names 1=mapping values 1, Chinese name 1=assignment 2 are replaced
It is changed to：Map Names 1=mapping values 2, Chinese name 1=assignment 3 replace with：Map Names 1=mapping values 3.
Second diffraction use-case, Chinese name 1=assignment 1 replace with：Map Names 2=mapping values 4, Chinese name 1=assignment 2 are replaced
It is changed to：Map Names 2=mapping values 5, Chinese name 1=assignment 3 replace with：Map Names 2=assignment 3.
3rd diffraction use-case, Chinese name 1=assignment 1 replace with：Map Names 3=mapping values 6, Chinese name 1=assignment 2 are replaced
It is changed to：Map Names 3=assignment 2, Chinese name 1=assignment 3 replace with：Map Names 3=assignment 3.
4th diffraction use-case, Chinese name 1=assignment 1 replace with：Map Names 4=mapping values 7, Chinese name 1=assignment 2 are replaced
It is changed to：Map Names 4=assignment 2, Chinese name 1=assignment 3 replace with：Map Names 4=assignment 3.
In an embodiment of the present invention, if between Map Names in initial test case corresponding to multiple signal names to be replaced
Correlation be or when, it is exhaustive derivative that multiple signal names to be replaced are carried out with permutation and combination.Using permutation and combination exhaustion side
Method is derived, and thinking is simple, and programming and debugging are convenient.
The generation method of automatic test case in the automobile controller of the embodiment of the present invention, believe according to sending signal and measuring
Substitution Rules between number are replaced operation to initial test case, generate final test case, improve test case
Readability, and test case can be reused.
