Abstract: Techniques for generating a test case involve: acquiring a first set of coding sequences representing a first set of test cases selected from a test case set for product testing. A test element in a test case of the test case set is coded based on the position of the test element in the element hierarchy of the test case set. The techniques further involve: generating a second set of coding sequences by performing a random variation related to at least one test element with respect to the first set of coding sequences; and generating a second set of test cases based on the second set of coding sequences. Accordingly, product testing and development may be automated, and the case set may change dynamically in a way that is adapted to product development while significantly reducing the overhead of designing and reviewing test cases throughout the product life cycle.

Abstract: Systems and methods are described for provisioning a desktop interface at a cloud service provider. An application service is introduced that selects a cloud service provider for provisioning a virtual machine (“VM”) that hosts the desktop interface. In an example, a user can request access to a virtual desktop from a client device. The application service can retrieve network latency data from multiple cloud service providers and select the provider with the lowest network latency for the client device. In some examples, the application service can select the cloud service provider on additional factors, such as the cost of provisioning the VM at each cloud service provider. The application service can provision the VM at the selected cloud service provider and facilitate access to the virtual desktop for the client device.
