Aspects of the invention include mutating each neural network of a portion of a first array of neural networks, wherein each neural network of the first array of neural networks is configured to select a respective sequence of test cases for testing a computing infrastructure. Causing each neural network of a second array of neural networks to select a respective sequence of test cases for testing the computing infrastructure. Generating a child neural network by performing a crossover operation between a mutated neural network of the portion of the first array and a neural network of the second array of neural networks, the child neural network generating a new sequence of test cases for testing the computing infrastructure.

Reinforcement learning for testing suite generation

Method and apparatus for system testing. A code base is accessed. A first section of the code base that is explicitly covered by a first test case is identified. A second section of the code base is modified, where the second section is not explicitly covered by the first test case. The first test case is executed on the code base with the modification of the second section of the code base. Based on determining that the execution of the first test case fails, the second section of the code base is determined to be implicitly covered by the first test case.

Identification of related test cases and overlapping code under test

Modification-based multipathing code, includes receiving a modification to a portion of code of an application; modifying the application to include a portion of multipathing code comprising a first path corresponding to the portion of code reflecting the modification and a second path corresponding to the portion of code independent of the modification; and configuring the application to execute either the first path or the second path as a default execution path.

Modification-based multipathing code

A multipathing code package including multiple code sections is provided. The multipathing code package includes at least different first and second versions of a particular code section among the multiple code sections. Processing circuitry of a data processing system executes the multipathing code package. Execution of the multipathing code packages includes executing a first version of the particular code section. Based on detecting an occurrence of an execution failure in the first version of the particular code section, the processing circuitry rewinds execution and replays the particular code section through execution of the second version.

Resilient error handling through multipathing code

Multipathing code execution based on failure severity includes: detecting a corresponding error in each path of a plurality of paths of a portion of multipathing code of an application; identifying, from the plurality of paths, a path having a lowest error severity; and resuming execution of the application using the identified path.

Multipathing code execution based on failure severity background

One or more systems, devices, computer program products and/or computer-implemented methods provided herein relate to data drift detection in an edge device. A system can comprise a memory configured to store computer executable components; and a processor configured to execute the computer executable components stored in the memory, wherein the computer executable components can comprise a verification component that can verify accuracy of a first model and accuracy of a second model to detect data drift associated with an edge device that is deployed without network connectivity; a computation component that can compute at least a first ratio based on the accuracy of the first model and the accuracy of the second model; and an analysis component that can use the at least the first ratio to determine whether performance degradation of at least one of the first model or the second model is a function of the data drift.

Drift detection in edge devices via multi-algorithmic deltas

Aspects include receiving a notification that a value of a data element stored in a source storage location in a source format has been changed to an updated value. The change is replicated to a plurality of target storage locations. The replicating includes, for each of the plurality of target storage locations, determining a target format of the data element in the target storage location. The target format is one of a plurality of different formats, including the source format. Each of the different formats provide a different level of data protection for the data element. In response to determining that the target format is not the same as the source format, the updated value of the data element is converted into the target format, and the updated value of the data element is stored in the target format at the target storage location.

Distribution of user specific data elements in a replication environment

A described method includes receiving, by a database system, an instruction to change a first data element in a table in a database, which includes a first copy and a second copy of the table. A first entry is created in a first change-table. The first entry includes an updated value for a first data element. A second entry is created in a second change-table. Creating the second entry includes, changing the updated value into a ciphertext if the first data element is secured, and storing the ciphertext into the second entry. If the first data element is non-secured, the updated value is stored into the second entry as is. The second copy of the table is modified using the second change-table. The second copy of the table is used to respond to subsequent queries.

Secure data replication in distributed data storage environments

Techniques for an expertise score vector for software component management are described herein. An aspect includes determining a size and an amount of time corresponding to committed code contributed by a first developer to a first software component. Another aspect includes determining a time per unit of contribution based on the size and amount of time. Another aspect includes updating component mastery metrics corresponding to the first software component in an expertise score vector corresponding to the first developer based on the time per unit of contribution. Another aspect includes assigning the first developer to a developer tier based on the component mastery metrics. Another aspect includes assigning a work item corresponding to the first software component to the first developer based on the developer tier.

Software developer assignment utilizing contribution based mastery metrics

Aspects of the invention include receiving a notification that a first logical grouping of code segments of a software application is being changed. Comparing the first logical grouping to a second logical grouping of code segments from a change history of the software application, where the first logical grouping and the second logical grouping both relate to resolving a common software application issue, and where the first logical grouping and the second logical grouping include at least one common code segment. Identifying a first code segment of the first logical grouping that is different from a second code segment of the second logical grouping. Determining that given the at least one code segment is changed a probability that the second code segment has been changed is greater than an threshold value. Sending a notification based on the difference in the probabilities being greater than a threshold value.

Using false positives to detect incorrectly updated code segments

Aspects of the invention include receiving a new problem record. A corpus of existing problem records that were previously assigned to problem record owners and grouped into documents based on their assigned problem record owners is accessed. Each document in the corpus has an assigned problem record owner. A document in the corpus that is most similar to the new problem record is identified. The identifying includes comparing text in the new problem record to text in the documents. The new problem record is assigned to the problem record owner that is assigned to the identified document.

Assigning a new problem record based on a similarity to previous problem records

Aspects of the invention include receiving, by a processor, a request to copy a code from a source file and receiving, by the processor, a request to paste the code into a destination file. Aspects also include creating, by the processor based at least in part on the request to paste the code, an entry in a database, the entry having an identification of the source file, an identification of the destination file, a location of the code in the source file, and a location of the code in the destination file.
