20180004641
The present invention relates to the testing of software, and more specifically, to a method, system and computer program product that implement aspects of workload and operational profiling, coupled with business analytics, thereby resulting in improvements in the testing of customer software.
In the field of software testing, as in many other technical fields, improvements are constantly being sought, primarily for cost and accuracy reasons. A fundamental goal of software testing in theory is to identify all of the problems in a customer's software program before the program is released for use by the customer. However, in reality this is far from the case as typically a software program is released to the customer having some number of problems that were unidentified during the software development and testing process.
A relatively more proactive approach to improving software testing is sought that employs traditional methods of understanding characteristics of clients' environments, augmented with a process of data mining empirical systems data. Such client environment and workload profiling analysis may result in software test improvements based on characteristics comparisons between the client and the test environments.
According to one or more embodiments of the present invention, a computer-implemented method includes preloading, by a processor, into a database data related to workloads and workload data, data related to analysis points, and customer data. The method also includes determining, by the processor, whether to modify a workload model, to run a workload or to perform one of post processing analytics or run time analytics. The method further includes performing, by the processor, one of post processing analytics or run time analytics of the data preloaded into the database.
According to another embodiment of the present invention, a system includes a processor in communication with one or more types of memory, the processor configured to preload into a database data related to workloads and workload data, data related to analysis points, and customer data. The processor is also configured to determine whether to modify a workload model, to run a workload or to perform one of post processing analytics or run time analytics. The processor is further configured to perform one of post processing analytics or run time analytics of the data preloaded into the database.
According to yet another embodiment of the present invention, a computer program product includes a non-transitory storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for performing a method that includes preloading, by a processor, into a database data related to workloads and workload data, data related to analysis points, and customer data. The method also includes determining, by the processor, whether to modify a workload model, to run a workload or to perform one of post processing analytics or run time analytics. The method further includes performing, by the processor, one of post processing analytics or run time analytics of the data preloaded into the database.
Additional features and advantages are realized through the techniques of the present invention. Other embodiments and aspects of the invention are described in detail herein and are considered a part of the claimed invention. For a better understanding of the invention with the advantages and the features, refer to the description and to the drawings.
The subject matter which is regarded as the invention is particularly pointed out and distinctly claimed in the claims at the conclusion of the specification. The forgoing and other features, and advantages of the invention are apparent from the following detailed description taken in conjunction with the accompanying drawings in which:
It is understood in advance that although this disclosure includes a detailed description on cloud computing, implementation of the teachings recited herein are not limited to a cloud computing environment. Rather, embodiments of the present invention are capable of being implemented in conjunction with any other type of computing environment now known or later developed.
Cloud computing is a model of service delivery for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g. networks, network bandwidth, servers, processing, memory, storage, applications, virtual machines, and services) that can be rapidly provisioned and released with minimal management effort or interaction with a provider of the service. This cloud model may include at least five characteristics, at least three service models, and at least four deployment models.
Characteristics are as follows:
On-demand self-service: a cloud consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with the service's provider.
Broad network access: capabilities are available over a network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops, and PDAs).
Resource pooling: the provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to demand. There is a sense of location independence in that the consumer generally has no control or knowledge over the exact location of the provided resources but may be able to specify location at a higher level of abstraction (e.g., country, state, or datacenter).
Rapid elasticity: capabilities can be rapidly and elastically provisioned, in some cases automatically, to quickly scale out and rapidly released to quickly scale in. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be purchased in any quantity at any time.
Measured service: cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). Resource usage can be monitored, controlled, and reported providing transparency for both the provider and consumer of the utilized service.
Service Models are as follows:
Software as a Service (SaaS): the capability provided to the consumer is to use the provider's applications running on a cloud infrastructure. The applications are accessible from various client devices through a thin client interface such as a web browser (e.g., web-based e-mail). The consumer does not manage or control the underlying cloud infrastructure including network, servers, operating systems, storage, or even individual application capabilities, with the possible exception of limited user-specific application configuration settings.
Platform as a Service (PaaS): the capability provided to the consumer is to deploy onto the cloud infrastructure consumer-created or acquired applications created using programming languages and tools supported by the provider. The consumer does not manage or control the underlying cloud infrastructure including networks, servers, operating systems, or storage, but has control over the deployed applications and possibly application hosting environment configurations.
Infrastructure as a Service (IaaS): the capability provided to the consumer is to provision processing, storage, networks, and other fundamental computing resources where the consumer is able to deploy and run arbitrary software, which can include operating systems and applications. The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications, and possibly limited control of select networking components (e.g., host firewalls).
Deployment Models are as follows:
Private cloud: the cloud infrastructure is operated solely for an organization. It may be managed by the organization or a third party and may exist on-premises or off-premises.
Community cloud: the cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be managed by the organizations or a third party and may exist on-premises or off-premises.
Public cloud: the cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services.
Hybrid cloud: the cloud infrastructure is a composition of two or more clouds (private, community, or public) that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load-balancing between clouds).
A cloud computing environment is service oriented with a focus on statelessness, low coupling, modularity, and semantic interoperability. At the heart of cloud computing is an infrastructure comprising a network of interconnected nodes.

In exemplary embodiments, the processing system 100 includes a graphics processing unit 130. Graphics processing unit 130 is a specialized electronic circuit designed to manipulate and alter memory to accelerate the creation of images in a frame buffer intended for output to a display. In general, graphics processing unit 130 is very efficient at manipulating computer graphics and image processing, and has a highly parallel structure that makes it more effective than general-purpose CPUs for algorithms where processing of large blocks of data is done in parallel.
Thus, as configured in
In accordance with one or more embodiments of the present invention, methods, systems, and computer program products are disclosed for utilizing various data to determine the effectiveness of a software testing procedure in accordance with one or more embodiments of the present invention.
One or more embodiments of the present invention allow an organization to better allocate its software test resources to provide for relative maximum productivity and value. Multiple system level test teams within an organization often run the same workload for a given software component, many times in the same configuration or model. Some test teams run these workloads frequently and others run them infrequently. Some test teams are relatively focused and diligent and run the workloads at high stress levels, while other test teams run the workloads at much lower stress levels and without much focus. As a result, some of the test teams are relatively more productive at finding defects in the software than others. Yet, it is almost always true that an organization's test resources are limited and risks must be assessed and taken.
Further, it is not at all uncommon to run tests and workloads that are not productive. Even with the best intentions, without empirical data to either confirm or deny the value of a test to the business, it is difficult to fund and manage a large test operation and know that the investment funds are used to get the best possible results. In the testing of customer software, results mean finding defects that the customer is likely to encounter, not just defects that can be found. Accordingly, embodiments of the present invention provide a method for determining, from a test investment perspective, how an organization can better spend its limited test dollars to yield the highest overall productivity and best return on its investment.
In addition, one or more embodiments of the present invention utilize undisputable facts, or workload run facts and problem discovery facts, to better ensure that accurate and factual information is used to determine an organization's investment in the software testing process. This is advantageous because systems level tests typically require expensive test system resources and highly skilled personnel.
Further, one or more embodiments of the present invention utilize a body of available customer data, test workload execution run facts data, and defect tracking data together with big data analytics to assist in a better understanding of the confirmation or denial of value of an organization's testing procedures. Not only may defect effectiveness be used as a criterion, but also workload variance is a relatively good measure of test effectiveness.

In exemplary embodiments, the functional features of the method 200 of
After a starting operation in block 204, blocks 208, 212 and 216 operate to store workloads and workload data in the database 304. The workload run facts database schema groups test run time data around a run facts ID. The run facts ID ties all of the preloaded schema data 208 with the run time workload and systems feedback data 232, 236 that makes up the big data portion of the data store in the database 304.
The preloaded data 208, 212, 216 includes data detailing the eligible test bed environments, the systems in the environments, specific testers in the environments, workload metadata including components under test and models, the analysis point groups and their analysis points containers of data points, the system configs or setup data, etc.
Once the data has been preloaded in the operations 208, 212, 216, the method 200 executes a decision operation in a block 220 which chooses from a model path that modifies the workload model in the block 224, a control path 228, 232 and 236 that runs a workload and collects and stores workload and systems runfacts therefrom, or a path 240 that allows for one of post processing analytics or run time analytics of the data using analytics tools. After the post processing or run time operation 240, the method 200 may then end in the block 244.
The run time data stored in the database 304 may include, for example, the workload controls, workload feedback, system feedback, system alerts, system errors, and workload errors. The run time data along with the preloaded data make up the body of runfacts that can be analyzed in the block 240 by post processing or run time analyzing the data using analytic tools such as, for example, analytic, modeling, cognitive, and reporting products to perform the analysis. The analysis performed in the operation 240 includes tying in all of the data down to the tester who ran the test and that tester's history to score multiple aspects of the runfacts such as, test to customer cluster proximity, test to customer activity intersection, most defect removing and productive workloads, environments, systems, testers, etc.
The post processing or run time analysis data includes the runfacts data store stored in the database 304 and test's defect tracking data store records 320 as stored in the database 308. Using both sets of data together in the near real time (i.e., run time) analysis or in the post processing analysis allows multidimensional analytics to be applied to help an organization understand the value of its tests, workloads, environments, testers, etc., to the organization.
In addition, once the workload run facts have been collected for multiple test teams and the various test environments, the aforementioned analytic, modeling, cognitive, and reporting products may be used in the block 240 to generate business analytics reports. These reports can be used to guide informed test business decisions about which test teams, which of their multiple test environments, and which workload models are most productive at finding defects. The workload configuration or model, the workload feedback, and the system feedback run facts can be correlated with problem discovery data to indicate test workload configuration or model, and test team and their multiple test environments effectiveness. This allows for grading of test efforts and their individual test environments regarding workload run participation and success or productivity based on 30, 60, 90, and greater than 90 day categories. Also, grading may be performed using a release by release scope. This grading information can be used along with problem discovery for each test team such as integration test and system test. Then within the overall scope of the test teams and their various test beds such as System Test's IST, DFSMS test, Combat, general SVT or Integration Test's, IT, Service Test, etc. use the analysis data to provide a correlation of workload run facts with problem discovery. Provide a grade from 0 to 100 to indicate the value of the test teams' participation in certain testing to determine the business value. This information may be used, for example, to invest in productive tests and divest in the tests that are not productive.
One or more embodiments of the present invention also provide the capability to add variability to workloads. This solves the problem of running the same workload, the same way, over and over again in multiple test teams in their various test environments. If the only variant of the repeated test runs with the same configuration is when new or modified code is dropped into the test, then once the code is available for test, running the same workload configuration or model over and over again and expecting is different result does not instill great confidence with regard to problem discovery.
Instead, one or more embodiments of the present invention involve test collecting workload run facts each time a workload is exercised in any of the available test environments. These workload run facts include the workload configuration or model information, workload feedback data, and system feedback data. The workload feedback data includes information such as the transaction mix or workload model, number of simulated users, the transaction rate, the failure rates per transaction, and the number and distribution of errors and failures. The system feedback data includes the empirical systems data that shows how the target component is being exercised with regard to functional activity as well as levels of load and stress. The empirical system data is comprised of performance and accounting data that is readily available in the system (e.g., Z) operating environment.
In addition, one or more embodiments of the present invention utilize a workload portal concept to develop test tooling. As a component of a workload portal, a DB2 database 304 may be created that is compatible with the analytics tool requirements. In this database 340, workload run facts data 312 is stored that includes the workload configuration model information. This includes the transaction or thread type mix and distribution of the transactions or threads. The workload model can be thought of as a mixer of sorts. If a workload has two transactions or threads, transaction A and transaction B, one can run the workload with an equal distribution for the two transactions. Thus, as the workload simulation runs, the transactions are executed with an equal distribution. Over the workload run each transaction may, for example, be run 100 times each. However, if the distribution were modeled or mixed to run transaction A with a distribution of one and transaction B with a distribution of five, then transaction B would be run five times for every time transaction A were run.
The model or mix can be stored in the DB2 304 as part of the workload run facts data. This model or mix is one part of the input to the analytics operation 240 and may, on its own, be used to create a useful analysis to determine workload model to defect discovery correlation. Additionally, if one includes workload feedback in the form of number of simulated users, transaction rate, total errors, and error distribution, then one can provide additional input into the analytics so that there is also an understanding of specific workload run time characteristics that correlate to productive defect discovery.
Additionally, the system feedback can also be used as input to the analytics 240 to enable understanding of which system pressure points correlate to productive defect discovery. All of the aforementioned workload run facts help to build an historical record of all testing for the given workload and target component(s).
In other embodiments, this historical data may be used in a similar approach to determine the best test team and test environment to trust with critical situation tests and recreate where time to resolution is a major business concern.
One or more embodiments of the present invention provide a solution that includes methods, systems and computer program products for a traditional processing environment or a cloud computing environment based set of exploitable services that make up a test workload execution diary that includes customer data contrasting and comparison. All information needed for analysis is brought together in a test control and data collection model called workload portal. The workload portal is a link between the test operator, the test system, and the test data. The services include workload modeling so that variation for workloads can be accomplished, system configuration so that workload and system setup can be varied, workload control to increase load, alter the execution model, provide visual workload feedback such as rates and errors, visual system feedback with customer data convergence visualization, system alerts for out of convergence issues, and all while making a diary of the workload run.
