Cloud Testing — The Future of Software Testing

Cloud testing is a method of software testing that renders various cloud computing services such as software, hardware, and other computing devices.

Cloud testing is a software testing using cloud computing, which means using resources found in the cloud. Resources may be any hardware, software, and infrastructure necessary to carry out the tests. Easy access to the cloud environment helps organizations approach software testing as an easily scalable, on-demand service. Over the last decades, traditional software testing incurs a high cost to simulate user activity from multiple locations. Most applications were running on client/server architecture, and data was tightly coupled with applications in client/server architecture.

Then the World Wide Web came along with N-tier application architecture where developers could create flexible and reusable applications. By segregating an application into tiers, developers acquired the option of modifying or adding a specific layer, instead of reworking the entire application. Technology innovation has further provided web access to people on the go via laptops and mobile devices.

Cloud-Testing Life Cycle

cloud testing lifecycle

The cloud-testing life cycle includes the following activities. Test Manager/Project manager/Test leader plays the role of Test admin. Test admin creates the test scenarios and designs test cases. Based on the scenarios and test cases, automated test script will be generated either by test admin or professional tester. Once a cloud service provider is available to test admin, he creates the user to give access to testers. 

Cloud-service provider set-up the infrastructure. Test users/Testers use the credentials to log in to the portal and can use all the assets available. The Cloud testing process starts here. Testers perform the testing. After completion of the process, cloud testing providers deliver the result.

Testing firewalls and load balancers involve the expenditure on hardware, software, and maintenance. In the case of applications where the rate of increase in some users is unpredictable or there is variation in deployment environment depending on client requirements, cloud testing is more effective.

Software testing has also undergone a long-drawn evolution cycle. From ad-hoc practices within different business units, it gradually evolved into a centralized Managed Test Center approach. However, the testing paradigm has changed and there are major challenges that need to be overcome, such as infrastructure availability, complexity, and increasing costs. Traditional application testing has its limitations as well, like latency, performance, concurrency, planning, and extremely expensive execution costs.

As technology innovation continues to make software available on various platforms and devices, software quality assurance has also caught up with the latest digital trends with its innovation. Cloud testing is a game-changer and surpasses the challenges faced with traditional testing. Setting up the cloud testing service is very straight forward for any organization: develop user scenarios, design test cases, select cloud services provider, set up infrastructure, leverage cloud servers, start testing, monitor testing goals and deliver results.

Types of Testing Supported  

  • Stress: Stress Test is used to determine the ability of the application to maintain a certain level of effectiveness beyond breaking point. Any application needs to work even under excessive stress and maintain stability. assures this by creating peak loads using simulators. But the cost of creating such scenarios is enormous. Instead of investing capital in building on-premises testing environments, cloud testing offers an affordable and scalable alternative.
  • Load: Load testing of an application involves the creation of heavy user traffic and measuring its response. There is also a need to tune the performance of any application to meet certain standards. Many tools are available for this purpose.
  • Performance: Testing performance under a particular workload is necessary. By using cloud testing, it is easy to create such an environment and vary the nature of traffic on-demand. This effectively reduces cost and time by simulating thousands of geographically targeted users.
  • Functional: Functional testing of both internet and non-internet applications can be performed using cloud testing. The process of verification against specifications or system requirements is carried out in the cloud instead of on-site software testing.
  • Compatibility: Using a cloud environment, instances of different operating systems can be created on-demand, making compatibility testing effortless.
  • Browser performance: Testing in various versions of browsers can be performed in the cloud.
  • Latency: Cloud testing is utilized to measure the latency between the action and the corresponding response for any application after deploying it on the cloud.
  • Strong points of cloud-based software testing:
  • The testing environment is dynamic and readily available. The on-demand nature of cloud-based testing is a big draw for organizations that need fast turnaround time and do not mind self-service. Most cloud testing applications work using a subscription model, so any user with a browser can register and start testing immediately.
  • The services are secure and affordable. Testing can be performed in either public, private or hybrid clouds. The public cloud is the most cost-efficient choice, and an acceptable level of security is maintained. For a mix of cost-effectiveness and top-tier security, many organizations opt for testing in a hybrid cloud.
  • Elastic scalability. Cloud-based testing allows you to ramp up and ramp down as your needs change or your project goals shift.
  • It allows for simple disaster recovery. In the cloud, recovery of any assets is quick and easy, not laborious or complex.
  • Cost-effective on the whole. Working via the cloud lowers costs associated with server maintenance and engineer labor.

Software Testing Futures for 2020

The field of software testing is undergoing continuous evolution. With the ongoing developments in technology, software testing experts have come up with the latest trends for the software testing industry.

In the field of software testing, the year 2020 will witness a shift from performance testing to performance engineering. Performance engineering will focus on important elements like configuration quality, convenience, practicality of use, and customer value to provide enhanced customer experiences.

Cloud testing is under constant evolution and is continuously bringing in new opportunities and challenges. Moving to a test to the cloud is more cost-effective for any organization as long as it does not include sensitive data and there is minimal impact on the organization’s business activities. Some may have the opinion that small business units will harness public clouds, while large enterprises will leverage private clouds for their cloud-based testing services. Whether the company is large or small though, the road to cloud-based testing is paved with its own set of challenges.

Some Cloud Computing Statistics That You Should Know

1. Cloud By 2015, end-user spending on cloud services could be more than $180 billion.

2. There is an estimated 1 Exabyte of data stored in the cloud.

3. Cisco forecasts that global data center traffic will triple from 2.6 zettabytes in 2012 to 7.7 zettabytes annually in 2017, representing a 25 percent CAGR

4. 59% of all new spending on cloud computing services originates from North American enterprises, a trend projected to accelerate through 2016.
