An organization is conducting a performance test of a public application. The following actions have already been completed:
• The baseline performance has been established
• A load test has passed.
• A benchmark report has been generated
Which of the following needs to be done to conclude the performance test?
After establishing baseline performance, passing a load test, and generating a benchmark report, the next step in a performance test is to verify the application's behavior under unexpected volumes of requests. This step, known as stress testing, ensures that the application can handle extreme conditions and sudden spikes in traffic without performance degradation. This is crucial for assessing the scalability and robustness of the application.
Load testing models expected usage. A stress test to determine stability would probably be a good thing to do.
Performance testing is a quality assurance test to determine a system or application’s functionality under a given workload. For cloud services, this information is useful for determining scalability settings. For example, scaling can be done via scale-up (more resources, such as memory, given to a VM) or scale-out (more VMs deployed). Applications may respond better to one or the other of these scaling practices. Regression tests are rerun on applications to ensure that any new changes did not break existing functionality. Otherwise, the application has fallen back, or “regressed,” to an earlier stage of functionality.
Functional testing is a quality assurance test that evaluates whether a system or application meets its specifications—does it do what it’s supposed to do? Usability testing is accomplished by end-users and provides direct feedback on the interface, features, and practical use. Usability testing helps ensure the application or server meets requirements and will actually be useful upon release.
Based on the information provided, option A, "Verify the application works well under an unexpected volume of requests," is the most appropriate next step to conclude the performance test. Here's why: Baseline Performance: The baseline performance has been established, which means you have a point of reference for the application's expected performance under normal conditions. Load Test Passed: The load test has already been successfully completed. This typically involves testing the application under expected levels of load. Benchmark Report: You have generated a benchmark report, which can be used to compare the application's performance against specific criteria.
Given this context, the next logical step is to ensure that the application can handle unexpected volume or spikes in requests. This is crucial because real-world scenarios often involve traffic spikes or surges that go beyond what's considered "normal" load. Testing the application's scalability and its ability to handle unexpected load is an essential part of performance testing. Options B and C, while important, are typically part of security and resilience testing, which are separate from performance testing. Option D, conducting tests with end-users and collecting feedback, is more aligned with user acceptance testing (UAT) and may not be the immediate next step in concluding performance testing.
A. Verify the application works well under an unexpected volume of requests. Explanation: Unexpected Volume Testing: After establishing a baseline, passing a load test, and generating a benchmark report, the final step in a performance test typically involves stress testing. This means verifying how well the application handles unexpected or peak volumes of requests to ensure it can maintain performance under extreme conditions
A. Verify the application works well under an unexpected volume of requests. This step is crucial to ensure that the application can handle unexpected spikes in user traffic without degradation in performance or availability. It validates the scalability and resilience of the application under varying load conditions. Explanation: While the load test passed, it might have been conducted under controlled conditions. Verifying the application's performance under unexpected volumes of requests helps uncover potential bottlenecks or weaknesses. This step aligns with the goal of performance testing, which is to assess the application's responsiveness, stability, and scalability under different workload conditions. It provides valuable insights into how the application behaves under stress, enabling the identification of performance degradation or failure points.
