What is Performance Testing?

Performance Testing is a type of software testing that measures the speed, reaction time, steadiness, dependability, versatility, and asset use of a software application under a specific outstanding burden. This is not tied in with discovering programming bugs or imperfections. The principal reason for performance testing is to check and wipe out the performance bottlenecks in the software application.

Performance testing will decide if the product meets speed, adaptability, and steadiness prerequisites under anticipated tasks. Mostly this testing characterizes how rapidly the Application reacts to clients’ or user requests.

Types of Performance Testing

To see how the product will perform on clients’ frameworks, there various sorts of execution tests that can be applied during programming testing. This is non-practical testing, which is intended to decide the preparation of a framework. There are different types of Performance Testing which are as follows:

  1. Load Testing
  2. Stress Testing
  3. Endurance Testing
  4. Spike Testing
  5. Volume Testing
  6. Scalability Testing

Load testing

Load testing estimates framework execution as the outstanding task at hand increments. That outstanding task at hand could mean simultaneous clients or transactions. The framework is observed to gauge reaction time and framework fortitude as the remaining burden increments. That outstanding task at hand falls within the boundaries of typical working conditions.

Stress testing

Dissimilar to stack testing, stress testing — otherwise called exhaustion testing — is intended to quantify framework execution outside of the boundaries of ordinary working conditions. The product is given more clients or exchanges that can be taken care of. The objective of stress testing is to quantify product soundness. When does programming fall flat, and how does the product recuperate from disappointment?

Spike testing

Spike testing is a kind of stress testing that assesses programming execution when outstanding tasks at hand are considerably expanded rapidly and consistently. The outstanding burden is past ordinary desires for short measures of time.

Endurance Testing

Endurance testing — otherwise called drench testing — is an assessment of how programming performs with an ordinary remaining burden throughout an all-encompassing measure of time. The objective of perseverance testing is to check for framework issues, for example, memory spills. (A memory spill happens when a framework neglects to deliver disposed-of memory. The memory hole can weaken framework execution or cause it to come up short.)

Scalability testing

Scalability testing is utilized to decide whether programming is successfully dealing with expanding the remaining tasks at hand. This can be dictated step by step adding to the client burden or information volume while observing framework execution. Additionally, the outstanding task at hand may remain at a similar level while assets, for example, CPUs and memory are changed.

Volume testing

Volume testing decides how productively programming performs with enormous, extended measures of information. It is otherwise called flood testing because the test floods the framework with information.

Performance Testing Process:

The approach embraced for performance testing can differ generally yet the goal for performance tests continues as before. It can help show that your software system meets certain pre-characterized execution models. Or on the other hand, it can help analyze the exhibition of two programming frameworks. It can likewise help recognize portions of your software that corrupt its exhibition. We cannot do Performance testing manually because of the following reason:

  • We need a lot of assets, and it turned into a costlier methodology.
  • The precision can’t keep up when we track response time physically.

The Performance testing process will be completed in the following steps:

  1. Identify the testing environment.
  2. Identify the performance acceptance criteria.
  3. Plan & design performance tests.
  4. Configuring the test environment.
  5. Implement a test design.
  6. Run the tests.
  7. Analyze, report, and retest.

performance testing process

Identify testing environment: This stage requires good knowledge of the physical test environment, production environment, and what testing tools are available. It is important to have a brief detail of the hardware, software, and network configurations utilized during testing before you start the testing cycle. It will assist analyzers with making more proficient tests.

Identify the Performance Acceptance Criteria: In this, we need to identify the performance scenarios based on the factors described below:

Most Common Scenario: In this, we consider the most commonly used scenarios. For example, in Gmail Application, we will check the performance of login, inbox, send items, compose mail, and logout.

Most critical Scenario: Critical scenarios mean routinely utilized and significant cases like Gmail application login, form, inbox, and logout.

Plan & Design Performance Tests: Decide how usage is probably going to fluctuate among end clients and distinguish key situations to test for all possible use cases. Recognize performance test situations that consider client changeability, test data, and target measurements.

Configuring the test environment: At this stage, we arrange a test environment before execution. we will install all the possible tools in the test engineer machine and access the test server. We also organize other resources.

Implement test design: At this stage, we will develop the performance test according to our design.

Run the tests: At this stage, we execute the test scripts, monitor and capture the data generated.

Analyze, report, and retest: At this stage, we will examine the data of the test result whether it meets the response time or not. After that, we will recognize the bottleneck (bug or execution issue) and run the performance tests again considering similar boundaries and various boundaries.

Why do we need Performance Testing?

Prior to going live on the lookout, the product framework should be tried against Speed, Stability, and adaptability under an assortment of burden conditions. On the off chance that the framework goes live without doing execution testing may cause the issues like running the framework moderately while at the same time getting to the framework by a few clients, helpless ease of use which is liable to pick up the awful standing and it influences the objective of the normal deal straightforwardly. Execution testing includes a scope of various tests, which empower the investigation of different parts of the framework. The Performance testing is advised about what necessities to fix prior to going live (fundamentally the issues are looked at under the assortment of burden conditions).
