Performance Testing vs Load Testing

More advanced tests may perform a series of steps on the website, such as clicking on key elements, buttons and fields and navigating through the site. One major consideration we mentioned earlier is if you are measuring client-side activity, or more specifically, Web 2.0 technologies. It is very important when it comes time for simulating user actions, like navigating, button clicks, entering date within forms, etc. If this is the case, the tool you choose should replicate this as close as possible using real browsers, because that is what your users are using. Geographic location plays a huge part of the customer experience, and if disregarded, will negatively affect the user experience. The LoadView solution provides users with the option to choose from over 40 load injector servers from around the world.

  • However, manual load testing will likely not return as valuable data as automated load testing that can gather and aggregate all the metrics for the system.
  • One thing to remember about JMeter is that it operates at the protocol-level only.
  • These queries can significantly slow down the application, negatively impacting user experience.
  • Load testing can be carried out in an environment that stimulates the production environment or in the production environment itself under defined settings.

It gives insight into performance issues and bottlenecks in a test environment, so your users don’t have to suffer through them in real life. Load testing goals may include a wide range of metrics such as the expected response time, the number of users each activity will support, what should happen in peak time, the number of many mobile users supported, etc. This process helps identify the point where the application behaves abnormally or deviates from the expected behavior.

Stress testing

With advanced analytics, teams using BlazeMeter can validate their app performance at every software delivery stage. For example, determine your acceptable response time or non-acceptable error rate. These KPIs should be derived based on product requirements and business needs. If you’re running these tests continuously, you can use baseline tests to enforce these SLAs. Scalability tests measure how an application can scale certain performance test attributes up or down. When running a scalability test based on a factor like the number of user requests, testers can determine the performance of an application when the user requests scale up or down.

For example, the piece of software under test is designed to serve X users (because it is an internal product of an enterprise and there are no more employees), so it does not make sense to conduct testing under a higher load. Therefore, it is sufficient to check if the performance is good enough and matches non-functional requirements or service level agreements. The performance testing life cycle describes the process of arriving at one or more of a series of tests that should be performed for measuring metrics of an application over time. Load testing should be performed before any major event that could potentially bring large amounts of simultaneous traffic to a website. Ideally, a test should be performed in a production environment during off-peak hours, before a public release of any new code, or website or web app updates.

When should you load test?

A load testing platform needs to evolve with the changing demands of our rapidly moving digital reality. At LoadView, our sole focus is on our clients’ successful load testing, on-demand and on budget. Load testing can be done manually by simply having many real users active in a system at once. However, manual load testing will likely not return as valuable data as automated load testing that can gather and aggregate all the metrics for the system. Additionally, when you consider the cost and time of the individuals needed to carry out manual testing, the opportunity cost may be far greater than simly using a cloud-based load testing solution like LoadView.

To simplify the process, you can record the scenarios and then edit them for accuracy. Run performance tests when you want to check your website and app performance, which may extend to testing servers, databases, networks, etc. If you follow the waterfall methodology, test at least once before you release a new version of your application. Load testing is the process of checking the behavior of the system under test under the anticipated load.

It tells how accurately the load testing is working under different test cases. It is usually carried out after the preparation of load test scripts/cases. Here, load means that when N-number of users using the application simultaneously or sending the request to the server at a time. It is recommended that if you expect your application to be scalable and to serve multiple applications, you must consider load testing.

If the system successfully responds to all requests within the required time, the system has successfully passed a capacity test. Load testing in Java can also refer to several different types of tests, as Java can natively run in many different environments on Java virtual machines. The EveryStep Web Recorder is a free web-based scripting tool that records every step of a web transaction and replays the script using a real browser.

Shift-Left Testing and LoadView

Response times, quality, and availability are critical factors that should be assessed before pushing applications into production. That is the whole point when load testing or API monitoring your website and applications. As stated before, the more you can ensure your site and applications perform well, the more likely customers will revisit a site or re-enter an application.
