performance testing software checks the actual software to the specifications mentioned before it is being built. The most basic function is to serve as a diagnostic tool to spot problems in communication. Scott Barber, a well-known test expert, said that it is difficult to determine an exact definition for performance testing because it works differently in different situations and various other companies.
What performance testing software?
Typically, software performance testing conducted to validate and verify software quality metrics such as durability, reliability, scalability, etc.
This software will experience a variety of load conditions and the response and the output will be measured to determine various factors.
Typed performance testing software
However, each company uses different types of test performance depends on the testing environment. Here is a look at some of the popular performance testing:
1. Load Testing
One of the most basic types of performance testing, load testing inspection method software load increases until the threshold is reached. Increased load means an increase in the number of simultaneous users, transactions, and the behavior of the software under test situation.
The main purpose of testing is to observe the response time to ensure that the software can withstand a load at any given time, which is why it is also called Volume Testing.
2. Stress Testing
stress testing is another common method of performance testing that check the stability of the software when the hardware including the CPU, disk space, and memory is not stable. This is a negative test where the software is loaded with a large number of concurrent users that can not be handled by the software.
This is the kind of non-functional testing because it tests the non-functional aspects of a website or application, which is done under controlled circumstances so as to capture the scenario definite and fix them.
This particular brand of testing using tools like sharpers stimulator of traffic and speed.
4. Durability Testing
In the endurance test, the software is tested with a fixed amount of load for a long period of time to observe the behavior of the system. For example, if the software is designed to work well for four hours, endurance is to be tested for a double time, which is eight hours.
Types of performance testing is used to check whether there is any system failure or memory leaks. durability testing is often referred to as the soak test.
5. Spike Testing
This test is done for longer periods of time to work anticipated. Any behavior that is not known tapped and improved upon.
6. Smoke Testing
In the smoke testing, the software is run on a very small load, which is much less than usual can handle. If the test produces smoke, then the software has errors in his writing.
This is one simple test that is used and usually the verification tests are performed before the software is launched or a larger test run.
As simple as it sounds, capacity tests is one in which the software is tested to handle the load required at any given time. When you know how many users the software you can handle, you have a better visibility of future events which may limit the application or website. This is a confirmation test to avoid problems in the future, especially when you want to increase the volume of data.
8. Component Testing
inspection of components function testing a specific part of the application or website. This simple but important aspects of the test, including file upload, a shopping cart, email functions, features graphics or search function.
9. Highlight Testing
In testing the top, you expose software by increasing the burden for small and peak time at the same time to analyze how the site or application will behave in real-life situations.
10. Scalability Testing
This kind of performance testing is usually performed during software development and prior to launch. In testing the scalability, you check how the site or application is a program that other software will be added to the server or to find a way to improve loading time. The main purpose of the test is to determine what tops the software will prevent more scaling.
Common problems observed during Performance Testing:
conducted performance tests to ensure the system is free of errors, so ready to be launched on the market. Let’s look at some common problems you may encounter during performance testing.
1. Poor Scalability
This system is not capable of handling the desired amount of load that delays the loading time leading to unexpected benefits that can affect memory, CPU usage, disk usage, network configuration, and operating systems.
2. bottlenecking
This problem occurs when the data stream is stopped or interrupted due to the site or application is not capable enough to handle the load.
3. Not enough Hardware Resources
This means that there is a shortage of hardware that generates a lack of memory and CPU is not doing well.
4. Software Configuration Problems
This is a minor problem that occurs when the configuration settings are set lower than the system can handle. All you have to do is customize the software configuration settings, and it will work fine.
Here are Some of the Best Practice Software Performance Testing:
1. Run the performance tests as early as possible in the development process, so you can do a small test that success rather than one that will have many problems.
2. You have to remember that the test performance is not only for the whole system, but can also be used to test each piece.
3. You have to do some tests on one part to ensure that the test results are consistent.
4. Make sure you always involving IT developers and testers in the process so that all-around process and you do not need to continue between the two departments.
5. Before the test, make sure that you are in need of internal/external or a combination of both are required.
6. The design of a high-level plan before exam
7. Develop a script for a proof-of-concept for the application under test
8. Configuring the router configuration, database test set, the network is quiet, the test environment, etc.
9. Prior to the actual test dry run tests to check the script is correct or not
Software performance testing process
1. Identify the Test environment identification- physical test environment, the equipment needed, and objectives that need to be achieved.
2. Identify the performance acceptance criteria — Characteristics such as response time, throughput, and the intended use of resources and constraints
3. Plan and design tests- Prepare test environment, select the desired tool, designing strategies, etc.
4. Configuring the test environment — Prepare the necessary resources to carry out the test
5. Carry out the test design — Developing the design according to the design of test
6. Run the test — Run, the monitor, validate and collect the tests and the test data
7. Analyse the results of tests, create reports, and retest — Consolidation of test data and analyse it. If tuning is required to do that and go for a re-test.
Conclusion
Software Performance testing is a key process that can determine the success of your software. If you want to know how your application can perform in the real world talk to us!
