as an example, step S2 includes:
s21, performing word segmentation processing on the test requirement information to obtain word segmentation results;
for example, for a sentence input by a user, using a custom dictionary and a stop word dictionary, stop words are removed from the sentence, and then word segmentation is performed by using a Chinese word segmentation tool. The custom dictionary contains test case names, script names and the like stored in the database server; and the stop words are words such as ' having ', ' and punctuation marks and the like in the sentences, which have no influence on the meaning of the sentences, and the word segmentation result can be a set formed by single words.
S22, inputting the word segmentation result into a pre-established intention classification model, and identifying the intention of a user;
the user intention comprises generating a required test script, executing a required interface test case or test script, and inquiring the interface test case or test script;
s23, extracting slot position information from the test requirement information;
the slot position information comprises a name slot and a number of slots, for example, 10 vehicle orders are given to me, wherein 10 is the number of slots, and the vehicle order is the name slot. The number slots can be obtained by part-of-speech recognition of the word segmentation result, and the name slots can be obtained by dictionary matching.
And step S24, generating a corresponding test instruction based on the user intention and the slot position information.

And taking the intention category corresponding to the word segmentation result as the output of the single-layer neural network model, and training the single-layer neural network model based on a plurality of groups of the word segmentation result and the corresponding intention category to obtain the intention classification model.
As one example, the intent classification model may be implemented with the Google open source tool Tensorflow, where the word embedding layer uses the Tensorflow's own mapping tool to map words into vector form; the convolution layer carries out convolution operation on the input vector and carries out feature extraction; the pooling layer extracts the output vector of the convolution layer again to obtain the most important vector; the output layer performs classification calculation by using a softmax classifier, calculates the probability of each category, and the category with the highest probability is the intention category of the current input sentence.
And step S3, calling a pre-stored interface test case and/or test script according to the test instruction to generate test data.
The interface test cases and test scripts stored in advance can be written and stored in the database by a tester, and the written interface test cases and test scripts can be directly imported and used, wherein the interface test cases comprise actual request heads, request bodies, request addresses, assertion contents, parameters required to be extracted in response to results and the like. The test script is used for processing the test case to develop a test.
