Cloud Testing

What is Cloud Testing?
Cloud testing is the process of using the cloud computing resources of a third-party service provider to test software applications. This can refer to the testing of cloud resources, such as architecture or cloud-native software as a service (SaaS) offerings, or using cloud tools as a part of quality assurance (QA)strategy. Cloud testing (also termed cloud-based testing) is used to assess web applications (or websites) for scalability, performance, security, and reliability.
As the name indicates, this form of testing is performed on a third-party cloud computing environment that houses the required infrastructure to perform tests. The various types of cloud testing processes allow you to test software and hardware without the usual constraints of a limited budget, geographical issues, multiple test cases, costs running high per test, etc. Cloud testing can be valuable to organizations in a number of ways.
For organizations testing cloud resources, this can ensure optimal performance, availability and security of data, and minimize downtime of the associated infrastructure or platform.

Cloud Test Use Case:-

  • To understand the concept better, let us consider an example of this cloud testing tutorial.
  • Your team has worked hard on the feature development of a web application (or website).
  • Still, your organization has limited (and non-scalable) infrastructure as far as cross browser testing is concerned. Should you release the product by testing only on the most popular web browsers?
  • Definitely not as you have cloud-based testing to your rescue. With a cloud-based cross-browser testing platform, testing can be performed remotely and securely on numerous combinations of browsers, devices, and platforms (or operating systems).
  • Keep the worries about the infrastructure’s scalability on the back burner as you do not own the infrastructure☺.
  • The result is improved test coverage, faster TAT (Turn Around Time), and much-better product quality.

Types of Cloud Testing :-
While Cloud testing in broad terms refers to testing applications through cloud computing resources, there are three main types of cloud testing that vary by purpose:
Testing of cloud resources:-
The cloud’s architecture and other resources are assessed for performance and proper functioning. This involves testing a provider’s platform as a service (PaaS) or infrastructure as a service (IaaS). Common tests may assess scalability, disaster recovery (DR), and data privacy and security.

Testing of cloud-native software :-
QA testing of SaaS products that reside in the cloud.

Testing of software with cloud-based tools:-
Using cloud-based tools and resources for QA testing.

Benefits of Cloud Testing:-
Here are some of the primary benefits associated with cloud testing:-
1. Cost-effectiveness- Cloud testing is more cost-efficient than traditional testing, as customers only pay for what they use.
2. Availability and collaboration- Resources can be accessed from any device with a network connection. QA testing efforts are not limited by physical location. This, along with built-in collaboration tools, can make it easier for testing teams to collaborate in real time.
3. Scalability- Compute resources can be scaled up or down, according to testing demands.
4. Faster testing- Cloud testing is faster than traditional testing, as it circumvents the need for many IT management tasks. This can lead to faster time to market.
5. Customization- A variety of testing environments can often be simulated.
6. Simplified disaster recovery- DR efforts for data backup and recovery are less intensive than traditional methods.

Example of Cloud Testing:-
Cloud test environments can be used to perform a broad range of functional and nonfunctional tests for customers. Here are some examples of software tests often conducted in cloud environments:-
Functional Testing –
Includes smoke testing, sanity testing, white box testing, black box testing, integration testing, user acceptance testing and unit testing.

System Testing –
Tests application features to ensure they are functioning properly.

Interoperability testing –
Checks that application performance is maintained across changes made to its infrastructure.

Stress Testing –
Determines the ability of applications to function under peak workloads while staying effective and stable.

Load Testing –
Measures the application’s response to simulated user traffic loads. Latency testing. Tests the latency time between actions and responses within an application.

Performance Testing –
Tests the performance of an application under specific workloads and is used to determine thresholds, bottlenecks and other limitations in application performance.

Availability testing –
Ensures an application stays available with minimal outages when the cloud provider makes changes to the infrastructure.

Multi-tenancy testing –
Examines if performance is maintained with additional users or tenants accessing the application concurrently.

Security testing –
Tests for security vulnerabilities in the data and code in the application.

Disaster recovery testing –
Ensures cloud downtime and other contingency scenarios will not lead to irreparable damages, such as data loss.

Browser performance testing –
Tests application performance across different web browsers.

Compatibility Testing –
Tests application performance across different operating systems (OSes).
