Embodiment 1
According to embodiments of the present invention, provide the device embodiment of a kind of test case appraisal procedure, it should be noted that, can perform in the computer system of such as one group of computer executable instructions in the step shown in the schema of accompanying drawing, and, although show logical order in flow charts, but in some cases, it is possible to be different from the step shown or described by the execution of order herein.
Fig. 1 is the schema of a kind of optional test case detection method according to embodiments of the present invention, and as shown in Figure 1, the method comprises the steps:
Step S102, it is determined that the function to be measured of automobile controller;
Step S104, the expected test result that statistics produces after using the function to be measured of testing case automobile controller and actual test result;
Step S106, according to actual test result to the level of coverage of expected test result, assessment test case is to the coverage of the function to be measured of automobile controller.
In fact, for the automobile controller that is specified, it can have multiple function, also, the function to be measured of automobile controller can by multiple, at this, it is possible to specify a kind of as current function to be measured. For example, it is assumed that certain automobile controller has the function of the motor rotating speed in control shelves position, motor rotating speed and specified gear, now, it is possible to specify the function (hereinafter referred to as shelves position controlling functions) of control shelves position is as current function to be measured.
Assume that the automobile installing above-mentioned automobile controller has 5 shelves positions, it is respectively 0,1,2,3,4, when using testing case above-mentioned shelves position controlling functions, the expected test result of 0,1,2,3,4 totally 5 shelves positions should be produced in theory, consequently, it is desirable to the theoretical test result of 0,1,2,3,4 is all added up in expected test result. And when adding up the actual test result of 0,1,2,3,4, it is necessary to opening above-mentioned test case, test 0,1,2,3,4 grade of position of above-mentioned automobile controller, the actual test value now recorded is exactly the actual test result of 0,1,2,3,4.
Wherein, when actual test value comprises the actual test result of 0,1,2,3,4 totally 5 shelves positions, show that the coverage of the function current to be measured of automobile controller is 100% by this test case, namely cover completely; Otherwise, show this test case can not cover completely the function current to be measured of automobile controller.
Pass through above-described embodiment, the expected test result of test case, the statistics of actual test result can be realized, and whether test case covers the assessment of the test result likely occurred of function to be measured, reach detection test case to the object of the coverage of whole test demand, thus achieve whether detection test case exists repeated test or test leakage to prevent causing the technique effect reducing test efficiency and waste testing cost.
Can selection of land, according to actual test result to the level of coverage of expected test result, the coverage of the function to be measured of automobile controller is comprised by assessment test case:

S12, the expected test result produced after using the function to be measured of testing case automobile controller according to data type statistics.
Each item function to be measured has the functional attributes of oneself, and like this, although data volume is uncertain in test result, but its data type is certain, such as, be this data type can be the one in following type: enumerate type, numeric type, boolean's amount type. Specifically, when the shelves position controlling functions that function to be measured is automobile controller, it is contemplated that the data type of test result for enumerating type, e.g., aforesaid 0,1,2,3,4 etc.; When the motor rotating speed controlling functions that function to be measured is automobile controller, the data type of expected test result is numeric type, as, under nominal situation, if motor rotating speed is 800-4000, then [800-4000] is normal numerical range, now all data scope can be divided into three sections, be respectively [minimum value-800), [800-4000], (4000-maximum value]. Test result data it should be noted that, for numeric type test result, it is assumed that expected results scope comprises three sections, as long as then can fall into these three sections of data areas respectively and namely shows that test case can cover all demands of current test function completely. In addition, for boolean's type test result, it is contemplated that the set of test result be 0,1}.
Pass through the embodiment of the present invention, it is possible to according to the functional attributes of function to be measured, the expected test result that flexible geo-statistic produces after using the function to be measured of testing case automobile controller.
Can selection of land, according to data type statistics use testing case automobile controller function to be measured after produce expected test result comprise:
S14, when data type is single data type, the single expected test result that statistics produces after using the function to be measured of testing case automobile controller; Or
S16, when data type is for combination data type, the combination expected test result that first statistics produces after using the function to be measured of testing case automobile controller, wherein, combining expected test result is obtain by all single expected test result combination that all single data type forming combination data type is corresponding.
For the test result of single data type, the general only corresponding data of each test result, such as, for the test result of shelves position controlling functions, in test result set, the corresponding data of each test result, such as 0 or 1 or 2 or 3 or 4 etc.; For the test result of combination data type, each test result generally can corresponding multiple data, such as, for the test result of shelves position motor rotating speed controlling functions, in test result set, corresponding two data of each test result, as, 1 grade and 800, wherein, 1 grade and 800 is exactly combine expected test result, and it is that the test result of the test result by shelves position controlling functions and motor rotating speed controlling functions combines. Combine expected test result set then to obtain by all single expected test result combination that all single data type forming combination data type is corresponding. Like this, under reasonable operating mode, so that it may to add up the set of the combinations of values of the test result likely occurred.
Pass through the embodiment of the present invention, it is possible to according to the data results feature of test result, the expected test result that flexible geo-statistic produces after using the function to be measured of testing case automobile controller.
