An efficient state-machine-based pattern matching technique processes tokens in an input queue and identifies patterns in the sequence of tokens that match one or more predetermined input patterns without backtracking. Tokens can include data or no data and a time component. The tokens can be a stream of data generated by a sensor, which transforms a physical property into a digital quantity. The pattern matching technique processes the input queue in a single direction, and does not examine any previously examined token. In an implementation, specific patterns to be matched are specified using a state machine, where the state machine is specified in a state table and operates using a state stack.

A debugger executes on a computer system to receive a first debugging command from a client, where the first debugging command sets a first instruction in the reactive application to suspend execution of the reactive application, and where during execution of the reactive application the first instruction is triggered which suspends execution of the reactive application. Responsive to the execution of the reactive application being suspended, a system clock of the reactive application is replaced with a substitute clock and the substitute clock is paused. The debugger then receives a second debugging command, where the second debugging command triggers a second instruction in the reactive application to continue execution of the reactive application. Responsive to the execution of the reactive application being continued, clocking of the substitute clock is continued.

A selection of a plurality of graphical user interface (GUI) components of a GUI is received. The selection is received so that the GUI can be tested. Attributes of the selection of GUI components are determined. Using the attributes, a default procedure for testing the GUI is determined. The default procedure includes a first set of input values for GUI components of the plurality of GUI components. The default procedure includes a first sequence in which the first set of input values are provided. Modifications to the default procedure are received. Using the modifications, a final procedure with a second set of input values provided in a sequence is generated. The GUI is tested with the final procedure. Testing the GUI includes providing the second set of input values to respective GUI components in the second sequence.

A computer-implemented method, computer program product, and system is provided for determining test case efficiency. In an implementation, a method may include determining each code unit executed by a test case in a test suite including a plurality of test cases, wherein a product-under-test includes a plurality of code units. The method may also include determining an execution time for the test case. The method may further include calculating an efficiency rating of the test case based upon, at least in part, a number of code units executed by the test case and the execution time for the test case.

Systems and methods for debugging tenant code for a multi-tenant system. A tenant code debugger may be installed on a user computing device, and connected to the multi-tenant system over a stateful connection. When an interested event occurs, the multi-tenant system may route execution to the user computing device for local debugging. A proxy may be used for the communications between the tenant code debugger and the multi-tenant system. When interaction with the multi-tenant system is needed, a request may be sent to the multi-tenant system which may interpret the request, execute to fulfill the request, and send the result back to the tenant code debugger, so that execution of the tenant code can be continued in the user computing device. The tenant code is uploaded to the multi-tenant system after debugging.

Replicating on a test server a production load of a production server. The production load can be created on the production server by processing client requests received from clients. While the client requests are processed, in real time, the production load can be replicated to generate a replicated production load that represents the client requests and defines state information representing unique states formed between the production server and the respective clients. In real time, the replicated production load can be communicated in order to replicate the production load on the test server.

A developer analytic module executing on an integrated development environment provides location tracing of a software development toolkit and automatic updates of the SDK. The developer analytic module further provides a user interface that enables a developer to select one or more functional modules to be included in a SDK to be installed at the developer's IDE.

A method for agile software development comprises receiving by a VM a command by a first version of a software component running on a first virtual machine, wherein the command may be executed by the software component, passing the command to a hypervisor along with an output file including a functionality identifier corresponding to the command and identifiers for versions of the software component to which the command is applicable, and transferring the command to a second VM for an execution of the functionality if the identifier of the second version of the software component was included in the output file. Additionally, the method may include sending a freeze command by the hypervisor to the second virtual machine if the identifier of the second version of the software component is not included in the output file.

This disclosure relates generally to systems integration testing (SIT), and more particularly to dynamic java message service emulator. In one embodiment, non-transitory computer-readable medium storing computer-executable trend analysis instructions is provided. The instructions may include instantiating, via one or more hardware processors, a dynamic enterprise java bean. The instructions may also include receiving, via the one or more hardware processors, a request at the dynamic enterprise java bean. The instruction may include generating, via the one or more hardware processors, a query for business rules based on the request. Additionally, the instructions may include configuring, via the one or more hardware processors, the dynamic enterprise java bean using the business rules. The instructions may further include processing, via the one or more hardware processors, the request using the configured dynamic enterprise java bean to generate a response.

An analysis and visualization depicts how an application is leveraging computer processor cores in time. The analysis and visualization enables a developer to readily identify the degree of concurrency exploited by an application at runtime. Information regarding processes or threads running on the processor cores over time is received, analyzed, and presented to indicate portions of processor cores that are used by the application, idle, or used by other processes in the system. The analysis and visualization can help a developer understand contention for processor resources, confirm the degree of concurrency, or identify serial regions of execution that might provide opportunities for exploiting parallelism.
