Cloud Testing Guide: Needs, Examples, Tools, and Benefits

The IT industry has been increasingly migrating to the cloud. You can view “the cloud” as computing services — including servers, storage, databases, networking, software, and analytics — over the Internet. Cloud is even being put to use in quality assurance (QA). One way to look at the cloud is to imagine running a factory that requires electricity. In a traditional setting, akin to traditional on-premises IT infrastructure, you might decide to build and maintain your own power plant. This approach ensures you have direct control over your power supply, but it’s costly, requires a lot of space, and you have to manage everything yourself, from installation to maintenance and upgrades.Instead of building your own power plant, you can connect your factory to the public electricity grid. In this analogy, this grid is managed by a utility company – a cloud provider. This comparison illustrates why many businesses are moving towards the cloud – it allows them to focus on their core activities without the complexities of managing IT infrastructure.

What is cloud testing?

Cloud testing is a software testing methodology where applications are tested within a cloud computing environment. In simpler terms, it means leveraging the power of cloud resources to test software more effectively.

Types of cloud applications tested

Cloud testing is applicable to any software application deployed in a cloud environment. Considering the deployment models, here’s a breakdown of the common types of applications cloud testing is used for:

  • SaaS (Software as a Service): These are web-based applications accessed through a subscription. Cloud testing is crucial for SaaS applications to ensure functionality, performance, scalability, and security across various user devices, browsers, and internet connections.
  • PaaS (Platform as a Service): These platforms provide tools and services for developers to build applications. Cloud testing helps ensure the PaaS platform itself functions correctly, offering developers a reliable environment to create and deploy their applications.
  • IaaS (Infrastructure as a Service): This provides virtual machines, storage, and networking resources. Cloud testing validates the core functionalities and performance of the IaaS infrastructure to ensure it meets the needs of applications deployed on it.

Why is cloud testing needed?

As more organizations move their applications and services to cloud environments, the limitations of traditional software testing, which is done on physical devices and in-house servers, have become prominent. Through cloud testing, you can avail yourself of many benefits that are otherwise hard to achieve.

  • More comprehensive test coverage: Imagine testing your software on hundreds of different devices, browsers, and operating systems. With cloud testing, you can access a vast pool of virtual machines, simulating real-world user environments for more comprehensive testing. This ensures your software functions properly for a wider range of users. Read: What is Test Coverage?
  • Scalability and cost-effectiveness: Testing complex software often requires significant computing resources. Setting up and maintaining an in-house testing lab with all the necessary hardware and software can be expensive. Cloud testing eliminates this need. You can easily scale testing resources up or down based on project demands, paying only for what you use. Learn about test scalability.
  • Faster time-to-market: Cloud testing tools often automate repetitive tasks, allowing you to run tests faster. Additionally, parallel testing, that is, running tests on multiple virtual machines simultaneously, is much easier in the cloud, significantly accelerating the testing process. This translates to quicker software releases. Know more about parallel testing.
  • Improved collaboration and accessibility: Cloud-based testing environments are accessible from anywhere with an internet connection. This enables geographically dispersed teams to collaborate on testing efforts more effectively. Additionally, remote testers can easily access the testing infrastructure.
  • Realistic performance testing: Cloud environments provide the ability to simulate real-world user loads and network conditions. This helps identify performance bottlenecks and ensure your software can handle peak traffic without crashing.
  • Security focus: Cloud testing platforms often offer built-in security testing tools, allowing you to identify vulnerabilities in your software early in the development process. This helps mitigate security risks before they impact real users.

Types of cloud testing

Testing cloud-based applications is quite similar to testing other applications. The methods are more or less the same; the tools available to do them will vary. The common forms of testing that are used in this process are:

  • Performance testing: This type of testing evaluates how an application performs under various load conditions. It includes:
    • Load testing: Simulates a specific number of users concurrently accessing the application to identify bottlenecks and ensure it can handle expected traffic.
    • Stress testing: Pushes the application beyond its normal capacity to determine its breaking point and identify potential failures under extreme load.
    • Scalability testing: Assesses how well the application scales up or down based on user demand.
  • Security testing: Focuses on identifying vulnerabilities in the application that could be exploited by attackers. This may involve simulating hacking attempts and penetration testing.
  • Functional testing: Verifies if the application’s functionalities behave as per the requirements. This can involve manual testing or automated test scripts. Read: Functional Testing Types.
  • Compatibility testing: Ensures the application functions correctly across different devices, operating systems, and browsers. Cloud testing provides access to a vast pool of virtual machines to simulate various environments. Read: Cross-Device Testing: Strategies and Tools.
  • Non-functional testing: Evaluates attributes of the application beyond core functionalities, such as usability, accessibility, and reliability.
  • Usability testing: Assesses how easy and intuitive the application is to use for target users. Cloud testing tools can help record user sessions and gather feedback.
  • Disaster recovery testing: Simulates a disaster scenario (e.g., hardware failure) to verify if the application and data can be recovered quickly and efficiently.
  • Browser compatibility testing: Specifically focuses on ensuring the application functions seamlessly across different web browsers and versions. Read: Cross-browser Testing.
  • Mobile testing: Tests mobile applications on a variety of real or simulated devices with different operating systems and configurations. Read: Mobile Testing: Where Should You Start?

Real-world examples of cloud testing

Most applications and websites today are cloud-based, meaning that cloud testing is being used. To help you understand better, here are some real-world examples. 

  • Cloud testing in e-commerce website
    Let’s look at load testing. An e-commerce website anticipates a surge in traffic during holiday sales. Cloud testing can simulate thousands of virtual users concurrently adding items to carts and checking out to ensure the website can handle the increased load without crashing.
  • Cloud testing in a mobile banking app
    Security is of utmost importance in finance and banking. Most banks have mobile apps these days. A mobile banking app needs robust security measures to protect user data. Cloud testing utilizes security testing tools to identify potential vulnerabilities like injection attacks or data breaches before the app is released to the public.
  • Cloud testing in a social media platform
    Let’s say a new feature is being added to a social media platform that allows users to create and share videos. Cloud testing, in this case, will involve automated tests that verify users can upload, edit, and share videos successfully across different devices and browsers.
  • Cloud testing in enterprise software
    A new enterprise software application needs to be compatible with various operating systems used within the company. Cloud testing provides access to virtual machines with different OS versions to ensure the software functions correctly on all target platforms.
