Common Performance Testing Errors

Common Performance Testing Errors

The development chain has several stages, and performance testing that includes load testing / stress testing is amongst the last of the pre-production stages. Some testers /developers could thus feel the urge to rush the results, to start testing in order to launch at the earliest. This could prove to be a costly error since performance testing requires time and patience, given that it is a highly complex process. Inadequate and inaccurate planning, scenarios that do not imitate real production environment and unrealistic load testing could lead to a disastrous launch, loss of time, money and the invaluable resources that went into the testing process. In order to ensure a top quality product and error free testing, it is necessary for testers to remain aware of the common performance testing errors.

Undefined goalsLoad testing becomes guesswork without measurable and clearly defined testing goals. In order to accurately align with business goals and requirements, the objectives for load testing must be defined before running tests. The testing goals, as mentioned should have relevance to the needs stated by the client.

No Realistic Test Environment

Without investing time and effort into building an environment that mirrors the actual production setting, load testing could throw up inaccurate results. There are innumerable components in a real production setting, which run intermittently such as databases, servers, tools, integrations, hardware, and many more – and without a realistic setting, all the efforts could prove futile.

Performance Testing Errors

Incorrect Time of TestingIt is a grave mistake to run performance testing at the end of the development cycle – it should be a part of the functional testing cycle. In most cases, the continuous integration system would have automated tests within, and hence it is possible run automated performance testing before the entire application becomes available.

Skimping to Rush Results While building load testing scenarios, most testers are tempted to compromise on time and quality. This can prove disastrous and throw up skewed load testing results. Even in the face of constraints – time, budget, and other resources, it is essential to ensure a thorough job of testing. If it requires an X number of users to test the system, it would be hazardous to use a lower number. Data randomization is another common error, which lesser skilled and less experienced testers and developers usually make.

Beginning with a Large LoadWhile load testing is meant to mimic the number of users in a realistic environment, highly skilled testers will avoid starting the tests with a final load in mind. Isolating bugs and errors becomes impossible with a large load, and testers must instead create a testing environment which grows gradually, allowing detailed monitoring for bugs at every stage.

Overlooking System ErrorsThe main focus of load testing is response time and performance measurement. It is necessary for testers to pick up and pay attention to errors such as incorrect data and strange ‘behavior’ of the system, even with good response times. This would help to identify the load related weaknesses in the system.

Forgetting to Document Test ResultsRunning and re-running load testing will not be accurate without comparing the results from each run. While it may seem laborious to track changes in each of the test runs, documenting the issues, settings of test environments and system under test, the objectives of each setting, and the results and inferences of each test run, is absolutely critical for top quality software. A good QA company with top class team will ensure that results are meticulously and accurately documented.

In Conclusion:

Any process is bound to have errors, and in the performance testing process too errors are commonplace. In addition, avoiding these mistakes may not guarantee a glitch free user experience each time, but understanding them and going the extra mile to rid the system of bugs will give your business the extra edge required to remain competitive.

Is there a Right time for Performance Testing?

Is there a Right time for Performance Testing?

In a world dominated by automated systems, digital interfaces, software products, and software-driven services, the business case for performance testing of software applications has never been stronger. Performance testing is a “type of software testing that ensures software applications will perform well under their expected workload.” Firms ensure end-users have the benefit of enjoying a lag-free application experience. Conducting performance testing prior to the public launch of an application prides the assurance that users can execute myriad computing tasks minus any delay, lag, or irritation.

A lackadaisical approach to performance testing may lead to the release of software products that run slow when multiple users log in simultaneously. The lack of automation and the associated performance testing also means that a software package will offer inconsistent performance across different computer operating systems. In addition, poor usability will impact the market reputation and commercial performance of a new software product.

We have listed some of the benefits that accrue from the disciplined use of performance testing services.

Certain software testing companies undertake to test an application on a variety of benchmarks, thereby allowing end-users to experience smooth performance. Typically, performance testing is executed to appraise the response time, processing speed, data transfer rate, reliability, throughput, scalability, and the optimal use of available resources by a software application. In addition, the elimination of performance bottlenecks remains one of the primary goals of modern performance testing suites and procedures.

The use of software testing allows software developers to detect and remove performance bottlenecks inside a suite of software. The deployment of competent performance testing services also helps software developers and architects to identify the locations of performance issues that may cause an application to fail. In addition, performance testing services help verify whether a system actually meets the specifications specified by the software manufacturer.

Is there a Right time for Performance Testing

Load testing remains crucial because it ensures the sustained performance of mission-critical applications. For instance, space satellite programs or life-saving medical equipment must operate on 100% certainty assured by the performance testing services of a performance testing company. A comprehensive performance testing regime assures stakeholders that the software applications will operate in the long term without any deviations.

Modern software testing companies perform a variety of load testing services for their customers and clients. Load testing is one of the services that checks the ability of a software application to perform under specified benchmarks of work load. The extensive use of load testing services ensures the detection and removal of performance bottlenecks inside a computer program. Similarly, endurance testing allows testers to assess whether a software application can continue to process preset workloads over an extended time frame.

Stress testing imposes extreme workloads on a software application in a bid to assess traffic or data processing capabilities. Software testing companies undertake such tests to identify the breaking point of a software application. The QA Services also include spike testing which examines a software package’s reaction to sudden workloads imposed by multiple users. Modern software testing services also include volume testing and scalability testing which check various limits and abilities built into a software package.

Conclusion

A variety of performance testing tools is available in commercial markets in modern times. Software developers and testers can pick automated testing tools to gain assessments that check a software package against a host of parameters. The widespread use of such services ensures a first class experience for every native of the digital age.

Best reasons to Invest in Performance Testing

Best reasons to Invest in Performance Testing

Performance testing is a type of testing executes to determine the performance of the software system like its response time, stability & scalability. A system might be working well with a select number of users when a couple of thousands of users use the system in a peak traffic session, there might be some issues that can adversely impact the software, causing inconvenience and an unpleasant user experience.

Invest in Performance Testing

In the rapidly advancing technology, there is no place or demand for applications that do not gratify the user expectations and hence enterprises cannot go by the adage “slow and steady wins the race” when it comes to their technology. Performance testing provides solutions to problems such as inefficient and slow applications, especially when used simultaneously by several users and when there seem to be inconsistencies across the different operating systems.

Invest in Performance Testing because it is Critical

Improves Response Timings Performance Testing builds and improves the speed of an application. A slow and inefficient system will never attract vast audiences. In fact, a poor system will serve to alienate viewers and restrict their usage of the application or website – which would not bode well for business. Performance testing checks the speed and improves performance, thus ensuring that the application works smoothly even under stress conditions.

Upgrades Scalability Performance Testing enhances the application’s ability to handle the increasing pressure by users without performance degradation. Enhancing scalability will help a system / application to handle future growth and the necessary requirements that would come with it. As competition grows within digital space, performance testing proves indispensable to strengthen applications to support future upgrades and modifications necessary for scalability of the application.

Enhances Stability It is crucial to identify the working of an application not only in its initial stage but during its entire ‘life’ and under stress conditions. The application must be stable and provide results with consistency to the audience irrespective of any changes in its features. Performance testing and the experts in the is realm can ensure improved and sustained stability of an application.

Improve Functionality of Application Performance Testing strengthens the functionality of application under real-world conditions by various experiments on the system, such as:

Load Testing – Testing the ability and response time of the system by exerting ‘load’ – this would determine the behaviour of the application when accessed simultaneoulsy by multiple. This test ascertains the maximum amount of load an application can withstand.

Stress Testing – This testing examines the potential of the system to withstand or overcome adverse conditions, while verifying its stability and reliability. The test evaluates how the system works under intense load conditions.

For Websites Supporting Direct Customer Interaction-Performance testing is a vital element for websites of companies that have a direct interaction with customers such as e-commerce, banking, and others. Companies are known to incur huge losses in the event of a website malfunction / crash. Even if the functionality is adequate, without proper and seamless performance and navigation, it is unlikely that users will stay – abandonment rates are high for such sites. Site and page loading speed are amongst the most critical factors for business websites, and if not considered and optimized accordingly, there is usually a significant negative impact on the bottomline of a business.

Eliminate bottlenecks and Improve Quality-Bottlenecks refer to both an overloaded network and where one component is unable to keep pace with the rest of the system, thus slowing overall performance. The purpose of performance testing is to find bugs or defects, and to provide solutions to eliminate them. With the fast pace of the world today, users want and expect a reliable and fast application. Performance testing ensures that applications perform optimally and are of a high standard. Testing ensures that all bottlenecks are identified and removed before they pose as a risk in terms of cost and the image of a company.

In Conclusion

The success of businesses depend largely on the websites and applications they create, and performance testing ensures that these methods remain seamlessly functional. An expert and professionally run outsourced QA company would not only help your company with framing testing objectives in line with the business goals, but would know exactly which technologies, software testing tools, and infrastructure would work best.

Performance Testing of E-commerce Applications

Performance Testing of E-commerce Applications

Key Factors to Keep in Mind

We all have shopping apps on your phones and enjoy the convenience of adding items to the virtual cart, making purchases as and when we want. We also like receiving updates about sale events, the launch of new products etc. Hence a well-designed e-commerce app is a must for any online store. No shopping portal can afford not to invest in load testing and performance testing of that app to ensure that it offers users an easy to use, glitch-free and fast experience.

An app load testing company will ensure that e-commerce applications do what they are supposed to: offering the most positive user experience possible.

Checking all objectives Performance testing has to examine every aspect of the app: its search functions, add to cart function, payment gateways and so on. If there is a blog section or a shopping guide segment, software testing services would have to check whether these pages are easily accessible and whether they point back to the sale page easily.

Load testing Traffic can slow down an app and cause people to leave their transaction incomplete. Hence, the behaviour of the app under heavy traffic is something that a QA company would have to examine closely. Performance testing by simulating situations with thousands of simultaneous users, would be necessary to gauge whether an app will perform well during, say, a sale event or a festive promotion.

Optimization for all devices Not only will testers examine how the app performs on various devices old and new, they also have to check compatibility with different operating systems. It is a good idea to examine the target demographic of the app and to identify the type and grade of device that demographic is likely to favour. A software testing company will examine why and when runtime error messages crop up, whether pages are displaying correctly and completely, the navigation speed, the readability and font size as well as other issues such as dead hyperlinks etc.

Cloud based testingToday, an important aspect of a positive shopping app experience is seamless performance on the cloud. For instance, users want to be able to add items to their cart on the go from their mobile app, but may prefer to complete their transaction on their desktop device. This is something for testers to examine. Cloud based testing is important because it can quickly simulate multiple users and provides scalability. Therefore, this type of testing now forms an important part of the entire performance testing process.

Geographical aspects to keep in mindQA services providers have to perform comprehensive tests that take into account the physical location of devices. Data services may be variable in terms of availability, speed and reliability. Various networks and the strength or weakness of the signal can hamper the shopping experience depending upon where the user is located. The app should be able to perform well under all of those conditions; regardless of where the user is. This is one of the reasons why businesses prefer QA outsourcing for testing their e-commerce app rather than performing in house checks.

Load testing of an e-commerce app will also examine the app’s vulnerability to attacks and fault tolerance. Testing will also shed light on possible backup failures, content analysis, personalisation capability, language support and display, order and payment processing and order tracking features. In other words, the performance testing process will examine all aspects of the app to ensure that end users have the most positive experience possible and businesses are able to maximise sales.

Performance Testing – An Overview

Performance Testing – An Overview

With practically all aspects of business now becoming digitised, there is a significant reliance on software programs, applications and systems. The streamlining and efficiency of business operations today rely heavily on smooth, seamless and glitch free performance of the software that they use. This makes load testing and performance testing vitally important processes for any business now.

Companies that are conscientious about quality assurance practices now choose QA outsourcing to ensure that they save time, resources and man hours that they would otherwise fritter away because of inadequately tested or unstable software.

What is performance testing?

When a load testing company is called upon to do this type of testing, what exactly does this mean? Here, the software testing company will examine the system’s ability to bear added workload during busier times and ability to handle multiplicity of transactions vis-à-vis response time, system stability, speed and scalability. Stress or fatigue testing is another part of the load testing process. It examines what happens when the system is put under the stress of work overload outside the usual parameters of usual working conditions. The point of failure and ability to recover from a crash are other aspects that testers will check.

A QA company will undertake spike testing and endurance testing to see how the system holds up when there is a sudden and large surge in workload as well as when the system is kept operational for extended periods of time. Testers will also look for any memory leaks that could impair performance. Scalability and volume testing are other testing modalities that companies offering QA services use for comprehensive testing.

Importance of performance testing

Load testing and testing various aspects of software for performance is vital for a number of reasons. It helps to identify bottlenecks and vulnerabilities in the system, which in turn will help prevent breakdowns and crashes while keeping the system safe from attack. Testers will identify performance problems or flaws that could cause the software to lag or malfunction and will also ensure that the system meets specifications. Hence a load testing service provider can help to streamline operations and reduce downtime; which can have the positive end result of reducing waste in terms of productivity, time and money.

The quality of the app here could literally mean the difference between a sale made or a sale lost. A slow, glitch or clumsily designed app could confuse or irritate a user, causing them to abandon their cart; turning to another online store with a better, faster, more attractive app! If, as an online retailer, you are wondering whether software testing is worth your while, consider some of these statistics: if it takes more than about three seconds for a website to load, over half of the customers – as many as 57% – will leave the website.

A delay of even one second, a glitch, or an unresponsive app lowers conversion rates. People simply don’t have the time and patience to wait for slow or heavy app that is clunky when moving between the different pages of a website. Customers today have so many other options that you want to ensure that you offer your customers a positive enough experience to make them want to stay with you!

Performance Testing Overview

From the foregoing, the vital role that performance and load testing play in the working of a business – in terms of both operations and profitability; becomes obvious. Engaging the services of a qualified QA company with an experienced, top notch team can be something that pays for itself in the long term – which is why do connect with us now.

Application Performance Testing – Planning & Execution

Application Performance Testing – Planning & Execution

When a person downloads or buys an application of any sort, the most important expectation that they have from it is that the app should perform well. It is be fast, easy to use and should efficiently do what it is supposed to. It other words it has to perform to expectations. Hence, performance testing and load testing are such important parts of a QA company’s job. We look at how a load testing company would typically plan for and test apps for businesses.

Planning and strategy for performance testing

A software testing company will usually build a whole test strategy and identify the kinds of tests that will help perfect an app. Testers would keep user expectations and component interactions in mind to prepare a detailed test strategy. Scalability and app capacity are aspects testers will examine, so that overall software and hardware costs can be reduced. In order to resolve production issues, testers will also verify that the given app adequately meets performance requirements. Load testing is carried out to analyse system reaction to all sorts of user loads, both current as well as anticipating any changed usage requirements of the future. Discussions with the technical team members, developers and other stakeholders may be necessary to these current and future requirements so that end users enjoy the best possible experience.

One of the main aims of performance testing is to identify performance bottlenecks by examining the module as a whole as well as by testing individual components. The test structure will depend upon business requirements and projected real load scenarios while also conforming to HTTP standards.

Application Performance Testing

Load testing will examine the app’s capacity and ability to manage the stress of concurrent users. It will try and minimise downtime and increase return on investment, while ensuring that the app enjoys a smooth rollout.

How a QA company carries out performance testing

QA services providers also bring a wealth of earlier experiences to the testing table. They will continue to carry out testing under consistent conditions to accurately identify the reasons behind issues that crop up. Continuous observation helps create a customised filtering system that helps testers get to the root of the problem. Since meeting deadlines for rollout is an important aspect of the testing process, software testing services will also implement baseline tests to try and quickly identify most major flaws in the system. This is a time saving device which a load testing company will often employ in order to save time and resources that would be expended in conducting full load tests.

Another aspect of performance testing is to factor in think-time. This is the time lag that will general occur when the end user is switching from one to another section of the app, or when they open their browser to cross check details such as pricing or specs, or when they pause to get their credit card or other payment details.

Application performance and load testing is an important process with far-reaching consequences. Hence, it makes sense to entrust the job to QA outsourcing rather than to handle it in-house. Connect with us to know why we are the go-to QA Company.
