A benchmark is a statistic or a point of comparison against which software products or services can be evaluated to assess quality measures in performance testing. A benchmark, to put it another way, is a set of criteria used to evaluate the quality of a software product or service. Benchmarking can be used to assess the quality of a software product or service.
For example, in order to be labeled a premier league player, a football player must meet certain criteria. The benchmark could be determined by, among other things, the number of goals scored in the preceding five seasons, ball possession in the first half, or the number of games played in the local league.
Benchmark Testing is a method of determining a repeatable set of quantifiable results that can be used to compare products and services. Benchmark testing findings are used to compare current and future software releases to their corresponding benchmarks.
A benchmark must be able to be replicated. For example, if reaction times vary too much with each iteration of a load test, system performance should be benchmarked. The response time must be constant under all load conditions.
It is necessary for a benchmark to be quantifiable. The user experience, for example, cannot be measured in numbers, but the amount of time a user spends on a webpage as a result of strong UI can.
Benchmark testing is a word that refers to both software and hardware testing, and it is regarded as one of the most significant responsibilities in the corporate sector.
We will explore benchmarking for a client-server application, or in other words, a web application, in this article
Benchmarking is possible for the following services −
The following points illustrate the significance of benchmark testing in the Software Development Life Cycle (SDLC). The benchmark software testing technique benefits a team of professional and knowledgeable testers in a variety of ways.
An application's performance qualities are evaluated. The performance should be constant, according to the organization's standards.
After the system has been changed, the consequences of the performance characteristics are examined.
Benchmark testing can be used to monitor a 'Database Manager's reaction under various scenarios.
It is possible to monitor the response time, concurrent users, and the website's persistent availability. It guarantees that the website adheres to the company's standards and best practices.
The application's performance meets the set SLAs (service level agreement).
To see how quickly transactions increase as more users are added.
Deadlock handling scenarios can be assessed in order to avoid deadlock issues.
The utility performance of a system can be evaluated. Data loading using multiple approaches.
After a new release, the impact, behavior, and attributes of an application.
Benchmark The tests are repeatable since they are conducted under the same settings each time. The outcomes of these exams are legally compared.
Performance testing aids in the improvement of the application's performance as well as functionality.
The most important aspect of the benchmark testing procedure is the test plan. The benchmark test plan is divided into the following steps −
Workload scalability and invocation
For benchmarking, Measurements should be collected and stored
Define the required time span and the endpoint of a test procedure.
Prepare an eventual plan in case a new test case fails.
Decide who has the authority to call the end process to a halt.
There are four phases involved in Benchmark Testing −
Planning Phase It is the first and most crucial stage. This phase receives special attention to guarantee that planning is error-free and that the other phases are both effective and efficient. This phase involves all of the relevant parties. The requirements and standards are identified and then prioritized. The benchmark criteria have been established.
Application Phase In the Application phase, the data obtained during the Planning phase is examined. To avoid error and hence increase quality, root cause analysis (RCA) is performed. The test procedure has objectives.
Integration Phase This phase serves as a link between the first two phases of planning analysis and the third phase, action. The outcomes or outcomes from the previous two rounds are communicated with anyone who is interested (Project Managers, Leads, stakeholders, etc.). The test procedure has objectives.
Action Phase This phase ensures that all of the improved actions, standards, and rule sets have been taken into account and successfully applied. The action plan is being created in preparation for implementation. The actions that were determined in the preceding steps are put into action and monitored. Mechanisms are being built to review the measures taken on a regular basis to ensure that the performance and benefits are maintained.
The initial data must be evaluated and updated for new users.
Ascertains that all software components are performing exactly as expected.
A precisely constructed application that can withstand and withstand all of the challenges of real-world use.
Software developers and testers may launch their apps with confidence. They are confident in the applications that have been released.
The effectiveness and performance of the recently released product are excellent.
Benchmark Testing Frameworks aid in the completion of some basic performance testing tasks.
These fundamental responsibilities include −
The most commonly used benchmark testing frameworks are Benchmark Framework 2.0 and TechEmpower.
Let's have a look at what TechEmpower has to offer. We'll take a quick look at its most important features −
It's a free and open-source framework for benchmarking.
It is necessary to set up the benchmarking environment correctly.
Benchmark Mode for comparing outcomes and Verify Mode for individuals who aren't experts are the two basic modes.
There are various files that are necessary, each of which is unique and may differ from system to system.
It includes a 'Benchmark Config File,' which defines a benchmark program's collection of test instructions and information.
The Object-Relational Mapper (ORM) is used to test databases, JSON Serialization, and other things.
When it comes to benchmark testing, consistency and control are very important.
To design test criteria and test data, you must first understand the system architecture.
Examine the initial static data and make changes based on feedback from a variety of consumers.
Wherever possible, look for 'Reset' functionality and establish a per-second transaction rate (this specifically deals with users transactions against a database)
Separate the system pieces based on their functions.
Every system has its own architecture and design, which must be taken into account when completing tasks. Testing for benchmarks
Different systems have varying degrees of complexity, necessitating different testing methodologies.
Benchmark testing has three primary components. They rare −
Workload Specifications: Identifying the type and frequency of requests to be sent to the test system.
Metrics Specifications: Decide which element will be measured, for example; the rate of download
Measurement specifications − figuring out how to measure the supplied elements in order to come up with appropriate values The following facts must be considered in order to conduct successful benchmark testing.
Ensure that all software components are in good functioning order.
The operating system and related drivers must function correctly.
Before conducting a benchmark, clear the system of prefetch and temporary files.
Check for operating system upgrades and real-world configurations by closing all background processes and programs.
Broken Links − When a link is clicked on a webpage, it results in an error or an empty page. This gives the appearance that the website is unprofessional, and it also results in a bad rating in search engine results. These broken links are recorded, which aids in re-directing or excluding them.
HTML Validation − This is necessary to ensure the website's compatibility. When a website becomes life, it should follow some coding guidelines in terms of HTML or XHTML usage, Cascading Style Sheets (CSS), layout definitions, and so on. HTML 5 introduces multimedia and graphical content syntactic enhancements. The main goal is to develop the language so that it can support the newest multimedia and other new features while also being easily accessible by humans and computers.
SQL − Benchmarking Considerations −
SQL queries (algorithmic complexity, I/O reduction, and determining if a correlated sub-query or a Left join is faster).
SQL server (batch requests per second, SQL compilations per second, SQL recompilations per second, maximum workers, idle workers, deadlocks)
CPU Benchmark − Benchmarking CPU clock speed, per-cycle registry calls, performed instructions, and disc architecture.
Configuration of Hardware (Domain Networks and Standalone PCs) − The CPU cooler, CPU socket, computer system cooling, etc. Processor, co-processor, scalable parallel processor, motherboard, chipset, memory, CPU cooler, CPU socket, etc.
Implementation − The application's benchmarks are determined by factors like robustness, efficiency, security, changeability, transferability, technical size, functional size, and so on.
Networks − A benchmark is set for any network (Ethernet, dial-up modems, ADSL, cable modems, LAN or WAN, or any wireless network, such as Wi-Fi). The KPIs (Key Performance Indicators) for voice and data are used to determine which elements should be included when benchmarking networks. Accessibility, retention, coverage, quality, application throughput, latency, session events, and other KPIs are among them.
Firewalls − The firewalls are rated based on the following criteria − Anti-spoofing filter (blocking specific IP addresses) deny or allow traffic, log traffic for analysis, intrusion detection, latest attack signatures, downloaded content digital signatures are verified before download, email, and links in emails, URL verification and filtering, accurate authorizations, and so on.
Benchmark Testing provides a repeatable set of quantifiable results on a system's performance in Software Engineering.
It's useful for testing load situations and determining system behavior in the face of a DDoS attack.
Workload specifications, metric specifications, and measurement specifications are all important parts of benchmarking.
Benchmark testing is done quickly and efficiently using a variety of tools and frameworks.
Mobile devices might benefit from benchmark testing as well.
