Shifting Left: The Top 5 Reasons to Test APIs and Components Early

Editor's Notes

• #3: Today’s applications continue to add more and more interfaces: Web/Mobile/APIs, Microservices/IoT They’re also incorporating new technologies like: WebSocket/HTTP/2 You need to be able to test whatever technologies your developers are sending along, and doing so without compromising your ability to deliver faster applications regularly Neotys has a proven track record of delivering the support of new technologies, first For example, NeoLoad was first to support HTTP/2, and WebSocket
• #4: Since API tests don't rely on a GUI, they can be created very early in the development process; this is low-hanging fruit that can be gotten out of the way early Determine the absolute maximum throughput of your API to set an upper bound of the performance that you’ll be able to achieve Find out how slow the APIs or any other web service respond under heavy load, while it’s still inexpensive to make any optimizations needed Pinpoint changes that are likely to influence the performance behavior of the component or API During certain Agile practices like continuous builds, the amount of time it takes to receive feedback from a GUI regression suite of tests when new code is checked in is too long. In those cases, getting started with testing earlier is better.
• #5: NeoLoad is designed to accelerate performance engineering processes across QA, Dev and Ops. NeoLoad is an Enterprise Performance Testing Platform enabling teams to share test assets and collaborate in real time on test results Collaboration speeds up testing for QA Reuse/share test assets and best practices Share test results Collaboration speeds up performance engineering processes Devs and Ops can see test results so they can fix performance issues as they are identified Devs can see in real time the result of performance tests so they do not have to wait until a test is completed to identify a performance issue NeoLoad delivers actionable insights not usable only by experts, but accessible to anyone involved in application performance NeoLoad is a Performance Engineering Platform that makes it easy and fast to access all load testing features Mobile testing fully integrated Cloud load injectors available in seconds Share license across teams to use the platform at its full capacity So, you can streamline your performance engineering practice, and optimize the collaboration between those who test and fix performance bottlenecks, to speed up your software delivery process
• #6: At Neotys, we only support load testing, and this is why we are able to provide the best available solution. We design our software to fit load testing into your Agile/DevOps processes, enabling seamless integration with your toolchain NeoLoad provides off the shelf integrations with the leading DevOps, test and APM solutions Continuous Integration Test automation Trend analysis Docker NeoLoad load generators are available as Docker containers, which makes it easy for organizations who rely on Docker, to deploy LGs when needed for testing; to remove them when the test is complete Other Testing Tools (Selenium, Tricentis, Perfecto, etc.) Script design automation: Re-use function test script/convert into load tests Script Maintenance: When an application changes, automatic update of scripts imported from Selenium End user experience: Combine server-side metrics (from NeoLoad) with end user metrics (Selenium, Perfecto etc.) with the application under load APM During load and performance testing of web applications, it is essential to collect metrics on the application components and application servers to effectively pinpoint/ understand performance issue cause(s). Combining information obtained from performance testing in NeoLoad with in-depth metrics from an application performance management tool, can help accelerate the identification of root cause in highly-complex applications NeoLoad starts a load test, tagging the requests initiated by NeoLoad virtual users so the APM tool can monitor this group independently. NeoLoad integrates with the following APM tools: Dynatrace, CA APM, AppDynamics, NewRelic And NeoLoad provides an API to… Customize NeoLoad virtual users behavior Pilot other tools (e.g. launch a functional test) Let NeoLoad be piloted by other tools (e.g. CI) Receive and send test data (e.g. receive end user experience metrics from Selenium, or send load test data to Tableau)
• #7: At Neotys, we believe that Speed and Quality can be achieved by “Testing Continuously” We design NeoLoad as a performance testing platform to empower you to test at every stage of the software development cycle in a continuous manner Test early and often. Identify performance bottlenecks early in the sprint, so they can be fixed rapidly – a far cheaper proposition than having to discover later during test or even production Run full system-wide testing to ensure your application’s reliability and speed under load. If a performance issue is detected, quickly provide a deep diagnosis to helps solve the problem faster Continuously collaborate on performance testing to support the performance engineering approach Key benefits of using Continuous Performance Testing include: Finding and Resolve Issues Earlier – Issues can be found at an earlier stage in the SDLC, then fixed quicker and at lower cost Faster Release Cycles – The automation built into leading-edge performance testing platforms save a huge amount of time. With this approach, testing becomes just another part of the build – not a manual step performed as an afterthought Deploy with confidence & lower risk – Improved code quality since everything is KNOW to perform as designed – under real-world loads
• #9: Introduction Ushahidi Architecture Full docker Adding photo to the post may increase the time to post event and overload the server (I/O, memory and CPU) DEVOPS Toolchain used in the team used many diffferent tools: GIT MAVEN SONAR DOCKER YSLOW SELENIUM AWS ECS (Docker over AWS) NEOLOAD NEOSENSE NTS NL WEB
• #10: So what you just saw was a live example of how a team uses the capabilities of our Continuous Performance Validation solution to get key benefits: With performance validation at every stage of the app dev lifecycle, you get faster performing applications. Leveraging automation and asset reuse make design and execution faster so that you have a quicker time to market for new features. Sharing results and user paths means that everyone is in the loop and speaking the same language when it comes to app performance.
• #11: Automation is 1 pllar of DEVOPS methodology Neotys API allows to be fully automated at each step Sample Design API could be illustrated by our Selenium integration Runtime API could be used to adapt hte load from a third party tool (Add user, remove users) Result API to retrive result from a third party tool without human interaction Ant and command line are still possible to offer a minimum level of integartion Deplouyment Wizard in NeoLoad to accelerate the testing process by addidng automation in the process (Framework parameter serach, redesign)

• #14: To summarize this presentation, NeoLoad provides the 3 main benefits By providing hyper accurate testing you can be confident your application will provide the best user experience, and that you can optimize your application infrastructure Because NeoLoad is faster, you can fit performance testing in Agile and support the organization wide effort to release faster Because NeoLoad provides confidence in performance testing and fits with time constraints of agile, Performance Engineers become digital performance confidence partners (and not a bottleneck)
