Top Six Delusions of Load Testing in an Agile Environment
Today, agile development methodology is seen as a quick and highly suited approach for various kinds of environments. Some of the practices that prove agile development is really fast are mentioned below.
- Everything is planned in sprints
- Efficiency is improved by measuring the team’s velocity
- A daily stand up meeting of 10-15 minutes help in coordination
- Integration is continuous
However, there is a propensity of putting performance testing at the end of the development process, as the developers hesitate to improve efficiency while the code is being written. Moreover, there are various misconceptions regarding performance testing in an agile methodology. But, you can try taking initiatives to put performance testing into your agile process. Some of them are discussed below.
- Performance testing can’t fit into agile
Performance testing is seen as a venture to push the entire environment to its end point. However, performance testing is much easier to fit into agile methodologies. Performance testing can be performed on individual modules just like functionality testing. In addition, you can try fitting performance testing into general Dev-Test-Ops cycle by developing a suite to test scenarios and critical transactions.
- Performance tests aren’t quick
This holds true in cases where it is required to operate the entire production environment, especially while performing complex stress test. However, you can segment the activities and try targeting the areas that require performance testing. In addition, you can think about performance SLAs upfront and include them in your specification process. This would allow you to automate the majority of the testing.
- Performance always comes after Functionality
There is a common belief that the earlier you detect a bug the faster it gets fixed at a much lower cost. This has driven many testers to code and create test cases alongside it. The same goes with performance testing, where a huge impact on the business could be due to poorly written lines of code. However, the issue can be traced while it is being written. You can test performance before your application’s functionality with back-end-interfaces like SOAP or Web Services.
- You can’t measure performance while the code is being developed
The complexity of the code increases as it gets built, changing the performance characteristics more frequently. However, performance testing could help the developers to know the code behavior early, if designed initially in the process. This would allow you to control the performance affecting parameters in the process.
- Load testing is the responsibility of an individual
Conventional ways of performance testing have been known to be an individual task. However, with modern agile practices everyone plays a vital role in ensuring the quality of a software application. For example, developers are also expected to come up with their own test cases. So, like functional testing, performance testing also involves the entire team.
- Load testing is more manual
There is always a manual aspect of testing, be it functional or performance. User experience plays the key role while testing, as it boosts your confidence to deliver the code. Moreover, there are many ways to automate performance testing. Considering it too manual is not justified in any way.
