Performance testing is critical in the development cycle of any software application, especially when considering future iterations and updated releases. At every step of the agile process, performance testing needs to be a priority for both developers and testers. Therefore, it’s very important to understand how to properly integrate such testing in an agile workflow.
What sorts of issues are commonly faced during Performance Testing?
Given the constant pressure of deadlines in our era of smartphones and rapid technological obsolescence, there’ll be a number of issues to deal with. The essence of this kind of testing is the emulation of real world behavior and the subsequent evaluation of how the application responds. In both new and legacy systems, accurate modeling of user behavior is a major obstacle in the development process. It’s also fairly difficult to rely on data generated in limited test environments, when predicting app performance in more multi-layered, complicated, and dynamic scenarios.
The need for Agility
The market demands higher quality apps in ever shortening time periods, so organizations are sufficiently motivated to adopt the Agile methodology in their app development process. In a waterfall model, performance testing tends to be conducted at the very end of the life cycle, but when it comes to the agile process, the exact opposite takes place; performance testing is implemented right at the beginning, in the earliest stages of the app design. This makes perfect sense – the design itself determines the function and potential robustness of the app, so integrating performance testing from the outset ensures that app quality and behavior is assessed and verified from start to finish. Analysis, design, coding, and testing all take place simultaneously.
Putting Agile and Performance Testing together
To ensure maximum efficiency in an agile scenario, identifying and resolving performance issues needs to be done at the level of your base code, to keep the rest of your pipeline free of any bottlenecks. So there are three stages to go through:
- Optimization: Tests are implemented to get rid of issues at the base code level
- Component testing: Resolves bugs at the level of app components
- App flow testing: Isolation and testing of crucial app flows determine UX consistency at difference load levels
Different Testing Models
Primarily, there are three models of iterative performance testing in agile environments:
- On Demand: This is the general starting point for organizations that want to fuse performance testing with agile processes. To put it briefly, developers need to be fully responsible for testing and tuning at all levels, under the supervision of a dedicated tester who takes care of performance evaluation.
- On Retainer: In this model, a tester is assigned to every app development project, who is not wholly committed to each task, but is on standby whenever developers require deeper technical assistance or bug resolution.
- Full immersion: This model is for companies that are serious about the delivery of quality apps, and that has now dedicated themselves to perfecting their performance testing. Testers are designated full time to monitor and verify each stage of development, and also to manage and orchestrate all the performance testing activities from beginning to end.
A Summary of Performance Testing Benefits in Agile Processes
It should be clear enough now that performance testing in your Agile environment has a number of benefits:
- Code optimization at the start of the project streamlines workflow in later phases
- App rejection risk is reduced due to stronger code and lower likelihood of memory leaks
- The duration for tuning and retesting is cut down significantly
- Higher chance of meeting product release dates
- Elimination of bugs in later phases
- Reuse of performance scripts allows you to save a lot of effort during the entire performance testing cycle
