When this step becomes ingrained in organizational behavior, developers can code for performance at the beginning of development cycles.Īs a first step, we recommend that QA teams have sufficient detail specified in their performance SLAs to support automated smoke testing. The goal for performance testers is to generate key parameters specified up front. SLAs can address all sorts of website metrics. The metrics of performance an SLA should address That way, developers will take performance into account as they develop the application, rather than approaching it as an afterthought. When testers specify SLA items during the application design process, they can turn them into requirements that are included on the Agile task board. Though they are not hard-and-fast contracts, SLAs determine desired performance benchmarks. For example, an SLA may state that all pages should load within 2 seconds or that the first page of search results be displayed within 4 seconds. From a testing perspective, the SLA details a measurable requirement that can be tested and marked as “pass” or “fail,” and usually relates to system availability and response time. SLAs will vary by organization, but every one of them will describe a specific benchmark or standard that the application must meet. Performance testers should think of their SLAs regarding performance parameters because it’s an implicit contract made with end users. Testing teams can factor performance and load testing into their continuous integration (CI) process by focusing on performance SLAs. The agreement allows the client to build its business and brand, knowing that the desired level of service will be executed according to operational specifications. For example, a large company that outsources its help desk operations may require all incoming customer support emails to undergo a triage that triggers a receipt confirmation email response within one hour. An SLA defines the level of service the service provider must deliver on to ensure a satisfactory customer experience, including the various attributes depicting how the service will be delivered and the different thresholds that define performance. What is a performance SLA?Ī service level agreement (SLA) is a contract between a service provider (be it in-house or an external service firm) and the client. To ensure success in their testing endeavors, QA teams and performance testers are increasingly relying on SLAs, including them on their Agile task boards. In these environments, testers must keep up with the speed of development while also meeting heightened expectations of quality. All these pressures commingle to create more Agile testing environments where testers often own the entire, end-to-end testing process, including automated, unit, regression, and load and performance testing. As a result, development teams are creating more code at a faster pace - code that needs to be thoroughly tested at an accelerated pace. To cope with these competitive pressures, many organizations have implemented DevOps and Agile and Agile-like development methodologies. For brands to survive in this ever-evolving and competitive marketplace, they need to balance created code speed and quality with that of the code they release. In today’s app economy where organizations must prioritize both revenue attainment and the customer experience, late-stage testing is no longer a sustainable strategy. In a DevOps world, late-stage testing is not sustainable Delaying a performance test for the “final sprint” as a pre-release task treats application testing like a waterfall development step, and assumes all cost and risk associated. This post discusses how to make load testing a regular “early and often” exercise via SLA elevation to the Agile task board. Furthermore, any delay in releasing a new feature or a new app can directly impact revenue, competitive position, brand, and adoption.Įven in organizations running an Agile development process, the performance test may not be conducted in a genuinely Agile way. Addressing problems after the fact is time-consuming and expensive. These code changes can impact other parts of the application, resulting in breaks. Whenever testers identify issues, developers must modify the long-finalized code to fix them. This approach creates a classic problem: late-stage testing. In fact, in many organizations, the performance test is frequently the last step - almost an afterthought –- conducted right before the application goes into production. Instead, they undertake performance and load testing after the application is complete, at the point where functional testing is applied. When it comes to application testing, many project managers and test leads do not routinely conduct performance and load testing early in the development lifecycle.
