What is Endurance Testing in Software Testing?

Endurance Testing

Endurance testing is a non-functional method of software testing in which software is evaluated at heavy load for a prolonged duration to determine the performance of a software program under repeated use. The key goal of the durability test is to validate that the program can manage a high load for a prolonged period without degrading reaction time.

This method of research is carried out at the end of the output run time. Endurance testing is a time-consuming method that can take up to a year. External loads, such as Internet traffic or user behavior, can be used. This distinguishes endurance testing from load testing, which usually lasts a number of hours.

Endurance means ability, but Endurance Testing can also be referred to as Capacity Testing.

Endurance Testing Objectives

  • Endurance testing's main target is to detect if there's any loss of data or leakage in memory.
  • To see how the machine works in long-term use.
  • To verify that the device reaction time is the same or higher than at the beginning of the procedure after a longer period.
  • To ascertain the number of users and interactions that a given device can handle while meeting output targets.
  • To balance future pressures, we must first determine how many extra resources (such as processing space, disc capacity, memory utilization, or network bandwidth) will be required to serve users in the future.
  • Endurance monitoring is typically performed by either overburdening the machine or reducing specific system resources and comparing the results.
  • It is carried out to make sure that no glitches or memory leaks exist following what is perceived to be a comparatively "natural" use cycle.

What to look for during Endurance Testing

The following items are evaluated during Endurance Testing.

  • Test memory leakage: Checks are performed to determine if there is any leakage of memory in the program, which may result in the system or operating system collapsing.
  • Test connection closure between the layer of the system: If the connection between system layers is not successfully closed, any or all modules of the system can stall.
  • Test database connection close successfully: The device would fail if the database link is not successfully closed.
  • Test response time: The device is checked for system response time as the program becomes less effective as a result of repeated use.

Endurance Testing Procedure

The following is the fundamental testing strategy for Endurance Test−

  • Testing Environment: Recognize the hardware, software, and operating system necessary for endurance testing, as well as delegate tasks and responsibilities within the team. Until running the test, the atmosphere should be prepared. You must also estimate the size of a typical database and its annual rise. As a result, you must test how your application will react after a year, two years, or five years.
  • Developing the Test Plan Scenarios: Test Case preparation, reviews, and implementation should be designed based on the purpose of the research − manual, automated, or a combination of both. Stress checking, breakpoint testing, and so on can all be included in the evaluation program. The application's breaking point is determined by stress-testing the device.
  • Estimation of Test Time: Provide an estimate of how long it would take to conclude the testing process. The number of testers participating and the number of test phases needed should be considered.
  • Risk Analysis: Evaluating the risk and responding appropriately for the preventative measures. Classification of test cases based on the risk factor, as well as identification of the risks and problems that the tester may encounter during the endurance test.
    • Can the level of success stay stable over time?
    • Are there any other small questions that have yet to be discovered?
    • Is there any outside interference that hasn't been addressed?
  • Test Schedule: Establish the budget and deliverables under time constraints. Endurance testing involves applying a large yet normal load structure of interactions to the system/application over a long period of time.

Endurance Testing Example

Though stress testing pushes the tested device to its breaking point, endurance testing pushes the application to its breaking point over time. For example, as the program operates for a prolonged period of time, the most complicated problems − memory leakage, database server use, and unresponsive machine − occur. If you miss the stamina checks, the odds of finding those flaws before deployment are slim.

Tools for Endurance Testing

  • WebLOAD
  • LoadComplete
  • Apache JMeter
  • LoadRunner
  • Appvance
  • LoadUI
  • OpenSTA
  • Rational Performance Tester

The Benefits of Endurance Testing

  • It aids in deciding how much work the System Under Load will bear.
  • Offers customers with reliable data that they can use to verify or improve their infrastructure needs.
  • Recognizes performance issues that may arise when a machine has been operating at a high level for an extended period of time.
  • Usual problems are found in smaller tailored efficiency checks, ensuring that apps remain usable even when subjected to a high load in a limited period of time.
  • The stamina test is also used to determine whether or not there is any output loss over a prolonged time of execution.

Endurance Testing's Drawbacks

  • It is always difficult to determine how much tension is appropriate to add.
  • Endurance testing can lead to the device and/or network failures, which can cause serious damage if the Test Environment is not separated.
  • Overstressing the machine will result in permanent data loss or corruption.
  • After the burden is eliminated, resource utilization remains very high.
  • Any components of the program fail to react.
  • The end-user notices uninitialized anomalies.


  • Endurance testing is a branch of load testing in software engineering.
  • Endurance monitoring is a time-consuming method that can take up to a year.
  • Verification checks are performed to confirm −
    • Memory leakage during testing
    • Time required to complete a test
    • Test the database relation, and so on.
