Continuous Load Testing: Reinventing Load Testing for Devops Continuous Load Testing: Reinventing Load Testing for DevOps tricentis.com Executive Overview Transformational initiatives such as Agile and DevOps are compelling software development teams to change their approach to load testing. This new approach involves extending beyond late-cycle load testing by performance testing specialists and empowering developers and testers to perform early, continuous load testing. Flood IO is built to enable load testing for DevOps, helping DevTest teams gain performance feedback rapidly and continuously. In addition to supporting industry-leading load testing tools, Flood integrates with Tricentis Tosca—allowing users to perform load testing with the same scriptless tests they use for functional testing. For DevOps, Load Testing Shifts Left Over 91% of organizations already have Agile or DevOps initiatives or plan to adopt them within the immediate future. As part of the process transformation required to adopt these more iterative and rapid methods of delivering software, organizations need to reassess ALL practices associated with software development and test—including load and performance testing. Traditionally, load testing has been deferred until the late phases of waterfall release cycles. Specialized performance testers applied legacy load testing tools to validate application performance prior to release. Why is this no longer sufficient? • With teams moving to more componentized applications (including cloud-native apps, microservices, etc.), an application involves many highly-distributed components—and a performance issue in any of them could have a ripple effect across the entire application • Now that new functionality is being released weekly, daily, or hourly, each team needs instant insight into whether their incremental changes negatively impact performance • The later you start load testing, the more difficult, time-consuming, and costly it is to expose, debug, and resolve performance problems In-depth load testing by performance testing specialists remains critical—but it doesn’t provide the level of fast, on-demand load testing that’s critical for Agile and DevOps. Developers and testers need a way to expose critical performance issues before new functionality progresses through the delivery pipeline. To achieve this, they must be able to easily: • Create load tests that provide fast feedback on the functionality they’re evolving 1 • Execute and scale those load tests as needed—without the exorbitant costs and efforts traditionally required to establish, configure, and maintain a performance test lab This is exactly where Flood IO excels. Flood IO: Load Testing for Modern Software Development Flood is a cloud-based load testing platform that helps teams see how their applications respond to globally-distributed load. By reducing the complexity traditionally associated with load testing, it extends load testing to developers and testers. Teams can start load testing their application components as they’re evolving them and continuously monitor performance impacts by integrating load testing into their CI/CD pipelines. Flood takes test plans from open source tools such as JMeter, Gatling, and Selenium and distributes them across readily available servers in the cloud. It also allows users to “flood” any HTTP endpoint on-the-fly. Teams can start load testing new functionality as soon as it’s developed. A developer or tester can instantly generate millions of globally-distributed requests per second from his or her local machine—without dealing with the hassles of requesting, configuring, or managing performance resources on-prem or in the cloud. 2 Thanks to Flood’s powerful scaling, the same core set of load tests can be leveraged to meet different performance testing demands throughout the delivery process. Load can instantly be scaled up or down, making it simple for any team member or automated process to generate the exact load needed for a particular goal or phase. Flood covers all load testing needs—from interactive developer performance tuning with real-time results, to automated CI-driven Continuous Load Testing under a typical load, to nightly testing under a heavier load, to comparing major feature updates versus previous performance benchmarks. The Flood API enables seamless integration into CI tools and a best-of-breed DevOps toolchain. Flood simplifies the following challenges associated with load testing: • Provisioning of load test infrastructure on demand • Distribution and execution of load tests at scale • Collection and aggregation of distributed results • Visualization and analysis of results in real time A New Era of Load Testing: Load Testing with Tricentis Tosca In addition to supporting traditional “protocol-level” level approaches to load testing (e.g., with JMeter and Gatling), Flood helps testers load test at the browser level. Without diving into technical details, there are two primary advantages of testing at this level. First, tests deliver more consistent results and are more resistant to change. Second, tests assess the application at the business (and user) level, which makes them more realistic. Until now, the main challenges with load testing at the browser level have been: • The level of work required to create effective browser-level tests • The level of resources required to run browser-level tests at scale The barriers to testing at this level have been removed now that Tricentis Tosca functional tests can be used for load testing with the cloud. Tricentis Tosca tests are not only simple to create, but also stable and easy to maintain. This makes them perfect candidates for the Continuous Load Testing that’s become critical for today’s DevTest teams. 3 For a concrete idea of how this plays out, consider this scenario: 1. Teams start off with load testing smoke tests—using their functional tests to assess how well “happy paths” through the application (also known as straight throughs) respond to a relatively light load. 2. As the application progresses through the pipeline, they extend these load testing efforts to include more test scenarios and larger loads. The varying degrees of load can be generated on-demand without any infrastructure hassles (Flood handles all the setup, configuration, and reporting). This way, the team can instantly generate load when they need it—without the costs and resources associated with traditional performance test lab. As with all Flood load tests, these tests can be seamlessly integrated into any CI ecosystem to enable Continuous Load Testing. 4 Wrap Up To conclude, we wanted to leave you with an idea of what’s so special about Flood. But we won’t bore you with details about the scalability of our shared nothing architecture, the advantage of our test-friendly pricing, our commitment to being a tool-agnostic solution, and so on. Instead, we’ll let a few of our customers explain why they’ve made Flood an integral part of their software delivery process. “Previously, we had very specialized tools for load and performance testing that were quite expensive and very richly featured, but completely disconnected from our everyday development tools. The main outcome of this was that we ended up with a couple of engineers who were quite good at load & performance testing with our enterprise tools while the majority of engineers found the barriers too great. With Flood, we have moved to an approach which is far more inclusive and utilizes many of the tools our engineers are working with on a daily basis.” - REA (Digital Advertising) “Rally Health began the new year with a bang. On January 1, we added more than 350 new organizations as clients, which meant that we suddenly had 5 million new users eligible to register. Add that to our current users, and it’s a bit like trying to expand your airplane in midair. With Flood load testing, it was smooth sailing — despite this massive influx of new users, our engineers report that we set up all these clients with no errors whatsoever, which surpassed even our most optimistic predictions.” - Rally Health “Flood helped us get started with load/stress testing quickly and without hassle. We are able to produce massive load tests with ease. We can easily test and monitor the resilience of all our applications and tune our instance sizes and auto scaling groups accordingly.” - Online ticket marketplace 5 Reinvent load testing for DevOps Start a free trial of Flood or get first access to Tricentis Tosca Flood About Tricentis Tricentis, the Continuous Testing Company, specializes in market leading agile software testing tools for enterprises.

    SAP S/4HANA Migration Guide Key Steps for Faster, Safer SAP Updates Tricentis | SAP S/4HANA Migration Guide | 1 SAP customers face a major challenge when migrating their businesses to S/4HANA. While upgrading to S/4HANA promises many benefits, it is not without risk. Not only will the migration impact SAP applications, but also the customizations and connected technologies (UIs, APIs, mobile, databases, third-party applications, etc.) that collectively run your business. Poorly planned migrations can lead to cost overruns, system downtimes, security lapses, and other serious business consequences. And the migration is only the beginning. With S/4HANA, SAP is promising more frequent SAP updates than ever before. To prepare for these updates, organizations need to be confident that their development, testing, and training processes can handle the speed and scope required to implement these updates safely, without risk to the business. Whether your migration approach is a new implementation (greenfield approach) or system conversion (brownfield or bluefield approach), this guide will show you how to gain certainty in your roadmap to S/4HANA and avoid false starts and unexpected costs along the way. In this guide, we’ll cover the 4 crucial steps to a successful S/4HANA migration: 1. Get a custom S/4HANA migration assessment to identify the technical and business risks involved. 2. Identify the testing needed to address those risks. 3. Optimize your test suite for resilient, risk-based testing. 4. Use a continuous testing platform to automate and accelerate ongoing testing. 1.

The purpose of this research was to come up with a method on how the performance and functionality of the REST APIs could be meas- ured and tested within Profit Software. The research consisted of two parts. First, I searched to find an existing software ca- pable of being used for testing REST APIs. After selecting the tool that would be used to create the performance tests, a local test environment was set up that allowed us to estimate the capability of the software and the method of testing itself. The local envi- ronment consisted of the same components and software that could be used also in the already existing test environments within the company. This way moving the tests from the local environment into the actual test environment went smoothly. With the help of this research we were able to detect issues with the functionality of some APIs, when they were under load. We were able to fix these issues in the imple- mentation during the development phase and after changing the implementation we could verify that the APIs functioned correctly by using these same tests.

These bottlenecks include finding and setting up test environments, test configurations, and test results implementation. These issues are not industry specific. They can be experienced in manufacturing, service businesses, and governments alike. They can be reduced by having a thorough understanding and a disciplined, mature implementation of Continuous Testing and related recommended engineering practices. The best place to start addressing these challenges is having a good understanding of what Continuous Testing is. Marc Hornbeek, the author of Engineering DevOps, describes it as: “A quality assessment strategy in which most tests are automated and integrated as a core and essential part of DevOps. Continuous Testing is much more than simply ‘automating tests.’” In this whitepaper, we’ll address the best practices you can adopt for implementing Continuous Quality and Testing on the AWS Cloud environment in the context of the DevOps model.

  • Modernizing SAP Testing in the Energy Industry
    Modernizing SAP Testing in the Energy Industry Tricentis | Modernizing Software Testing in the Energy Industry | 1 Despite the growing emphasis on digital transformation, the average test automation rate remains a dismal 18% overall— and 6% for energy companies, who are commonly working with complex systems including SAP and custom applications. This means that each time the SAP infrastructure or business processes change, enterprises rely on internal business users or dedicated manual testers to click through each critical business process and note whether the expected results are achieved at every step. As you can imagine, this is an incredibly slow and costly process: • Completing a single test cycle commonly takes weeks or even months • Testing is routinely cited as the #1 bottleneck to delivery speed • Testing consumes 30-40% of the average IT budget Now , energy companies are increasingly turning to SAP innovations such as SAP S/4HANA and SAP Cloud to optimize production, extend business processes to capitalize on new opportunities, and accelerate innovation across the value chain. As a result, the pace of change and the complexity of what needs to be tested are constantly increasing dramatically. This presents a number of challenges from a testing perspective: • Automated tests architected for previous generations of SAP platforms must be rebuilt. • Existing testing processes don’t suit the new faster (and more fragmented) release cycles, with different components evolving at different speeds. • Within the SAP ecosystem, testing must address SaaS cloud solutions such as SAP SuccessFactors, SAP Ariba, SAP Fieldglass, and SAP Hybris. • Reinvented business processes commonly extend beyond the SAP ecosystem, including APIs, mobile, mainframes, and so on—but legacy testing approaches often do not.
