A method and apparatus for upgrading libraries in a source code program by evaluating libraries in the source code program for predetermined selection criteria specifying library performance limitations to identify at least a first library which does not meet the plurality of predetermined selection criteria and then identifying a first alternative library that is suitable for substitution for the first library so that the source code program may be automatically modified to replace the first library with the first alternative library, thereby generating a modified source code program having an upgraded library functionality.

According to certain aspects of the disclosure, non-transitory computer readable media, systems and methods are disclosed for creating and executing test scenarios for automated testing of web pages. A computer system, for example, may perform operations including: recording one or more actions performed by a user on a web page, the one or more actions resulting in a web page element being displayed in the web browser application, recording an identifier of the web page element, in response to detecting a user input indicating a selection of the web page element, and recording a characteristic of the web page element; and generating, by the testing extension, a test scenario specifying a testable outcome resulting from the one or more actions, the testable outcome being an occurrence of an element having the identifier and the characteristic.

Mutation testing can indicate whether mutants of a software application, created by intentionally altering source code of the software application, are successfully “killed” by test cases executed against the mutants. Mutation testing can be performed via parallel threads by, within each parallel thread, modifying individual source code class files and recompiling the modified class files to generate and test mutants. Individual mutation test results produced within each of the parallel threads can be aggregated to generate an aggregated test result report that indicates overall testing metrics associated with the mutation testing across the parallel threads.

A method and apparatus for testing a map service are provided. The method may include: determining a to-be-screened service request based on a service request of an electronic map recorded in advance at a preset sampling frequency; screening the to-be-screened service request by using a static rule, to obtain a first valid service request set; screening the to-be-screened service request by using a dynamic test step, to obtain a second valid service request set; and testing a service of the electronic map based on the first valid service request set and the second valid service request set.

Technologies are described for ranking test cases related to changes in a software code base using at least a portion of a call graph that is generated from the software code base. The at least a portion of the call graph comprises method nodes corresponding to methods in the software code base. The method nodes represent control flow relationships between the methods in the software code base. The at least a portion of the call graph also comprises test case nodes. Each test case node is connected to one or more method nodes corresponding to coverage of the one or more method nodes by the test case node. Using the at least a portion of the call graph, the test case nodes are automatically ranked. Ranking of the test case nodes is performed by evaluating various criteria associated with the at least a portion of the call graph.

A system and method for determining a relative importance of a selected test in a plurality of tests, comprising a computational device for receiving one or more characteristics relating to an importance of the code, an importance of each of the plurality of tests, or both; and for determining the relative importance of the selected test according to said characteristics.

Methods, systems, and computer program products for path-coverage directed black box application programming interface (API) testing are provided herein. A computer-implemented method includes determining constraints based on inputs and corresponding outputs of an API in a production environment; generating initial test inputs based at least in part on the constraints; creating a program dependency graph based on trace sequences and request-response data obtained in response to providing the initial test inputs to an endpoint of the API; enhancing the program dependency graph by generating additional test inputs directed to one or more paths of the dependency graph; identifying, based on the enhanced program dependency graph, at least a portion of the API that is not covered by an existing test suite; and using the enhanced program dependency graph to generate new test cases for the test suite based on the identifying.

There is provided a regression test method, an electronic device and a storage medium, and relates to the field of artificial intelligence, such as artificial intelligence chips, cloud computing, intelligent voices, or the like. The method includes: when execution of any regression test is completed, determining a to-be-adjusted test case from test cases according to a current test result; and adjusting a randomization weight corresponding to a data range randomized by the to-be-adjusted test case in a current test.

Techniques for automated generation of inputs for testing microservice-based applications. In one example, a computer-implemented method includes: traversing, by a system operatively coupled to a processor, a user interface of a microservices-based application by performing actions on user interface elements of the user interface; and generating, by the system, an aggregated log of user interface event sequences and application program interface call sets based on the traversing. The computer-implemented method also includes: determining, by the system, respective user interface event sequences that invoke the application program interface call sets; and generating, by the system, respective test inputs based on the respective user interface event sequences that invoke the application program interface call sets.
