detailed description

Embodiments of the invention are described in detail below, examples of which are illustrated in the accompanying drawings in which the same Or similar reference numerals indicate the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the drawings are intended to be illustrative of the invention and are not to be construed as limiting.

A method and system for generating an automatic test case in an automotive controller according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

1 is a flow chart of a method of generating an automated test case in an automotive controller in accordance with one embodiment of the present invention.

As shown in FIG. 1, the method for generating an automatic test case in the vehicle controller includes the following steps:

S101. Generate an initial test case.

The initial test case includes a signal name and an assignment name corresponding to the signal name.

Specifically, when writing the initial test case, the signal name and its assignment name can be directly written in an easy-to-read language, and the writing mode can be “signal name=assignment name”, such as accelerator pedal=slam, key=ON file, Engine failure = level 3 fault, battery voltage = 12V, etc., writing is simple and convenient, and easy to read.

S102. Acquire an replacement rule between the transmission signal and the measurement signal.

In the embodiment of the present invention, the transmission signal refers to all signals including the signal name in the initial test case, and the measurement signal refers to all signals including the signal name in the test case applicable to a certain function test of the new software, wherein, the transmission signal There is a correspondence between the signal and the measurement signal. The replacement rule includes a logical relationship consisting of a signal name, an assignment name, a mapping name, a relationship between mapping names, and an assignment map name. The replacement rule can be expressed in a table, for example, it can be represented by Table 1:

Table 1

As shown in Table 1, the signal name is the language used to express the signal name used in the initial test case, that is, the Chinese name 1 in Table 1, which may be an accelerator pedal, a key, an engine failure, or the like. Assignment name is a specific signal name In all the initial test cases involved in the assignment name, the assignment name can have any number, that is, the assignment value 1, assignment 2, assignment 3 in Table 1, three assignment names, can be oil fierce Step on, ON file, level 3 failure. The mapping name must be a name recognizable by the test software. One signal name can correspond to multiple mapping names. There are four mapping names in Table 1, namely, mapping name 1, mapping name 2, mapping name 3, and mapping name 4. The relationship between mapping names has or is expressed in two ways, and its role is to make multiple mapping names simultaneously Have the role of a certain signal name, or use the joint action of multiple mapping names to equal the role of the signal name. The assignment map name must be a name that can be recognized by the initial test case. It can be a specific value, or a relational expression, or a curve, or even a complex function, that is, the map value shown in Table 1. 1. Map value 2, ..., map value 7.

S103. Perform an replacement operation on the initial test case according to the replacement rule to generate a final test case.

Wherein, the initial test case corresponds to the name and/or serial number of the final test case.

Specifically, as shown in FIG. 2, the replacement operation of the initial test case according to the replacement rule to generate the final test case includes the following steps:

S201: Determine a signal name to be replaced, and index the signal name to be replaced in the initial test case.

The signal name to be replaced may be the Chinese name 1 in Table 1.

S202. Determine whether the number of mapping names corresponding to the signal name to be replaced is equal to 1.

S203. If yes, replace the signal name to be replaced in the initial test case with a mapping name, and replace the assignment name with a corresponding assignment mapping name to generate a final test case.

Specifically, if the number of mapping names is equal to 1, as shown in Table 1, if only the mapping name is in the mapping name, the Chinese name 1 can be replaced with the mapping name 1, and the assignment name can be replaced with the corresponding assignment mapping name. That is, "Chinese name 1 = assignment 1, Chinese name 1 = assignment 2, Chinese name 1 = assignment 3" will be replaced by: mapping name 1 = mapping value 1, mapping name 1 = mapping value 2, mapping name 1 = mapping value 3 . After the replacement is completed, the generated final test case contains the replaced mapping name and its corresponding mapping assignment name.

S204. If no, determine a mutual relationship between the plurality of mapping names corresponding to the signal name to be replaced.

S205. If multiple mappings are named AND, replace each signal name to be replaced in the initial test case with a set of all mapping names, and replace the assignment name with the corresponding assignment mapping name to generate a final test case. .

For example, as shown in Table 1, if the relationship between multiple mapping names is AND, the Chinese name 1 = assignment 1 will be replaced by: mapping name 1 = mapping value 1, mapping name 2 = mapping value 4, mapping Name 3 = mapping value 6, mapping name 4 = mapping value 7 of the four sets; Chinese name 1 = assignment 2 will be replaced by: mapping name 1 = mapping value 2, mapping name 2 = mapping value 5, mapping name 3 = Assignment 2, mapping name 4 = assignment 2 of the four sets; Chinese name 1 = assignment 3 will be replaced by, mapping name 1 = mapping value 3, mapping name 2 = assignment 3, mapping name 3 = assignment 3, mapping name 4 = Assign 3 to the collection of 4 of these.

S206. If multiple mappings are named as a relationship, generate a derivative file of the initial test case with the same number of mapping names, replace the signal name to be replaced in the derived file with the mapping name, and replace the assignment name with the corresponding one. Assign a map name to get the final test case.

For example, as shown in Table 1, if the relationship between multiple mapping names is OR, the following four derivative test cases are generated:

The first derivative use, Chinese name 1 = assignment 1 is replaced by: map name 1 = map value 1, Chinese name 1 = assignment 2 replaced with: map name 1 = map value 2, Chinese name 1 = assignment 3 replaced with: map Name 1 = mapped value 3.

The second diffraction use case, Chinese name 1 = assignment 1 is replaced by: map name 2 = map value 4, Chinese name 1 = assignment 2 replaced with: map name 2 = map value 5, Chinese name 1 = assignment 3 replaced with: map Name 2 = assignment 3.

The third diffraction use case, Chinese name 1 = assignment 1 is replaced by: map name 3 = map value 6, Chinese name 1 = assignment 2 replaced with: map name 3 = assignment 2, Chinese name 1 = assignment 3 replaced with: map name 3 = Assignment 3.

The fourth diffraction use case, Chinese name 1 = assignment 1 is replaced by: map name 4 = map value 7, Chinese name 1 = assignment 2 replaced with: map name 4 = assignment 2, Chinese name 1 = assignment 3 replaced with: map name 4= Assignment 3.

In the embodiment of the present invention, if the relationship between the mapping names corresponding to the plurality of signal names to be replaced in the initial test case is all OR, the plurality of signal names to be replaced are arranged and combined exhaustively. Derived by the exhaustive method of permutation and combination, the idea is simple, and the programming and debugging are convenient.

The method for generating an automatic test case in an automobile controller according to an embodiment of the present invention replaces an initial test case according to a replacement rule between a transmission signal and a measurement signal to generate a final test case, thereby improving readability of the test case. And can make test cases reuse.

Replace the assignment name with the corresponding assignment map name to generate the final test case.

In the embodiment of the present invention, the processing module 33 is further configured to: when the number of mapping names corresponding to the signal name to be replaced is greater than 1, and the relationship between the plurality of mapping names is AND, each of the initial test cases is to be replaced. The signal name is replaced with a set of all mapping names, and the assignment name is replaced with the corresponding assignment map name to generate a final test case; and the number of mapping names corresponding to the signal name to be replaced is greater than 1, and multiple mapping names When the relationship is OR, the same number of initial names as the map name is generated. Start the test case's derived file, replace the signal name to be replaced in the derived file with the map name, and replace the assignment name with the corresponding assignment map name to get the final test case.
