What are the consequences of skipping Application Performance Testing?

 

implications-of-skipping-application-performancetesting

In the age of customers expecting instant gratification through digital devices and applications, businesses should not cut corners when it comes to delivering fast, responsive, and secure user experiences. Hence, in order to ensure that your organization’s software performs optimally and does not falter on parameters of speed, security, efficiency, scalability, responsiveness, and performance, it should be subjected to stringent application performance testing.

Types of performance testing

The criticality of performance testing in terms of assuring the stability, reliability, and scalability of an application is well established. The various types of performance testing underline its importance and relevance in ensuring customer satisfaction.

Stress testing: Here, an application is pushed beyond normal load conditions to check the components that fail first. In other words, it identifies the breaking point of the application.

Spike testing: Evaluates the capability of the application to handle a sudden increase in traffic volume.

Load testing: Evaluates the application’s performance under a high volume of traffic.

Volume testing: Evaluates the application’s ability to handle large data volumes and check its response time and behavior.

Scalability testing: Measure the application’s attributes like throughput, response time, transaction processing speed, network usage, and others.

Implications of skipping application performance testing

With customer satisfaction becoming the sole determinant in ensuring the success of any software application in the market, skipping performance testing can prove to be disastrous for business enterprises.

User dissatisfaction: Statistics suggest that users are unlikely to use an application and opt for its competitor if it fails to load within 3 seconds. Since the attention span of users is decreasing with each passing day, they want the application to load without buffering. It is only through a cogent performance testing approach that the application system can be maintained properly and any defects are fixed before being delivered to the end-user.

Fail to determine load threshold: Every software application should have a load threshold that shows the volume of traffic it can handle without facing issues like latency, downtime, or crashes. Performance testing helps in determining the load threshold the software can handle, and in its absence, measuring the application’s performance in terms of scalability, load capability, efficiency, and speed will not be possible. This can have serious implications for the business, especially during the days of high sales such as Black Friday, Christmas, New Year, and others.

If a sizeable number of users flock to your website or application on such days with the expectation of making sales but end up facing latency or downtime, the negative impression can drive away many existing and prospective customers. For example, thanks to the unpreparedness of eCommerce chains like Walmart or Costco to cater to the increased rush of online shoppers on Black Friday, Walmart ended up losing $9 million in just 150 minutes. Not to be outdone, Costco had to look at a staggering loss of $11 million due to its website crashing for more than 16 hours.

Losing brand reputation: Building a brand is important for a company to attract customers, and it often takes years to accomplish the same. However, one unfortunate moment of taking short cut or being unprepared can ruin the meticulously built brand reputation of a company. In the above-mentioned examples of Walmart and Costco, unsatisfied customers had flooded social media with scathing messages for these companies. As a result, these behemoths had to do with a lot of negative publicity and loss of brand equity. Such negative publicity can be the proverbial death knell for smaller companies as they will find it well-nigh impossible to crawl back.

Bottlenecks leading to poor quality: With users becoming more demanding regarding the quality of an application, the lack of pursuing a performance testing strategy can let the bottlenecks or glitches within the application remain undetected. These issues can cause the application to falter in terms of handling traffic, delivering accurate outcomes, speed, and efficiency. So, instead of addressing such issues beforehand and let customers enjoy superior experiences, the software can suffer from a series of inadequacies.

Instability: Your application must be robust and stable for the customers to use and derive a slew of benefits. If the right performance testing methodology is not used or skipped altogether the reliability, recoverability, and uptime of the application and its data can get compromised. In the DevOps scheme of development where continuous integration, testing, and delivery are the norms, skipping application performance testing can be detrimental for your business and reputation.

Conclusion

Quality assurance is the bedrock against which the performance of any software application is judged. Organizations should work towards creating a Centre of Excellence wherein testers can access advanced automation test tools and leverage them to strengthen the application’s performance. Further, to guarantee user satisfaction and delight, organizations should incorporate performance engineering in the SDLC. Skipping such an important part of quality assurance can have serious implications for the organization.

Discuss Test Orchestration and its Role in Achieving Optimal Quality of Software

Image
  In the DevOps approach of developing, testing, and delivering software applications, there is a need to accelerate testing within the constraints of budget and time. This entails automating the testing process as part of the testing strategy. In many cases, continuous test automation is often considered as a discrete step in the build pipeline rather than a sequence of steps. For any continuous testing strategy, all software applications need to pass through a series of tests before they pass muster in the crucible of quality. These may include unit testing, integration testing, functional testing, smoke testing, performance testing, security testing, and others. For DevOps QA testing, each of these tests should be subjected to automation to enhance quality, reduce test time, and improve the certainty of software behavior. However, merely automating the tests left, right, and center does not augur well when it comes to achieving an optimal quality level as well as minimizing the ...

How Customer Sentiment Analysis can Benefit Businesses

Image
  A customer may display varied emotions (positive or negative) while engaging with a brand. These emotions determine if the customer is likely to revisit the brand or junk it altogether. According to a McKinsey study, more than 85 percent of customers are likely to purchase from a brand again after having a positive customer experience. A negative customer experience, on the other hand, can reduce the number of customers by 70%. So, how do businesses know whether their customers are happy while engaging with their brand? Instead of merely depending on assumptions, the answer lies in analyzing customer sentiment. Customer sentiment analysis can let businesses know about the different emotions customers go through while dealing with a particular brand, product, or service. Customer experience insights can help brands offer more of the elements that make customers happy. Moreover, it can improve the customer satisfaction index, customer lifetime value, and customer loyalty, thereby ...

How QA Teams are Coping with the Pandemic

Image
  The COVID-19 pandemic has dealt a body blow to the global economy, with scores of businesses ending up on the losing side. As governments scrambled to contain the spread of the pandemic through massive and prolonged lockdowns, most sectors of the economy took a hit, leading to job cuts, revenue losses, and the shredding of reputations. The pandemic has destroyed the livelihoods of millions of business enterprises trying to come to terms with a hitherto unseen situation. The blow came as a double whammy for everyone as the world was coping with a prolonged recessionary trend in the pre-pandemic era. However, with signs of the pandemic fading in many parts of the world, albeit unevenly, global economic growth is expected to be 4.9 percent in 2022 (Source: imf.org). The economic rebound, though robust, is expected to be uneven across countries and sectors. So, on one hand, we have seen companies across domains going out of business. Many managed to sustain themselves and sail throug...
