Cloud Testing Interview Questions and Answers

Here are 20 commonly asked Cloud Testing interview questions and answers to prepare you for your interview:

1. What is cloud testing?

Cloud testing is a type of testing that is performed on applications or services that are hosted on a cloud computing platform. This can include testing of the cloud platform itself, as well as the application or service that is running on it. Cloud testing can be used to test the performance, scalability, and security of an application or service.

2. How do you perform Cloud Testing using AWS?

Cloud testing is a process of testing applications and services on a cloud computing platform. This type of testing is often used to simulate real-world user traffic and load on a system to see how it performs.

To perform cloud testing using AWS, you can use the AWS CloudFormation service to create and manage a cloud testing environment. CloudFormation allows you to provision AWS resources in a template, which can then be used to launch a cloud testing environment. Once your environment is up and running, you can use the AWS Elastic Load Balancing service to distribute traffic to your application across multiple Amazon EC2 instances. You can also use the Amazon CloudWatch service to monitor your application and system performance in real-time.

3. Can you explain the difference between functional tests and non-functional tests when performed on a cloud platform?

Functional tests are tests that check the functionality of a system, while non-functional tests are tests that check the performance of a system. When performed on a cloud platform, functional tests would check things like whether the system can connect to the cloud, whether the system can access the data it needs, and whether the system can perform the tasks it is supposed to perform. Non-functional tests would check things like the system’s response time, its scalability, and its ability to handle a high volume of traffic.

4. What are some of the popular cloud platforms for running automated tests?

There are a number of popular cloud platforms that can be used for running automated tests, including Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP). Each of these platforms offers a variety of services that can be used for testing, including virtual machines, storage, and networking.

5. What types of tests can be run through a cloud platform?

Cloud testing platforms provide a variety of services that can be used to test applications, including functional testing, load testing, performance testing, security testing, and compatibility testing.

6. How does cloud testing differ from regular software testing in terms of skills, tools, and techniques used?

Cloud testing generally requires a different set of skills than regular software testing, as it often involves testing in a distributed environment. In terms of tools and techniques, cloud testing may make use of virtualization and automation to a greater extent than regular software testing, in order to manage the increased complexity of the testing environment.

7. What are the benefits of using cloud platforms to run automated tests?

There are several benefits to using cloud platforms to run automated tests, including:

1. Increased flexibility – With cloud testing, you can easily scale up or down your testing infrastructure as needed, without having to make a large upfront investment.

2. Reduced costs – Cloud testing can be more cost-effective than traditional on-premise testing, since you only pay for the resources you use.

3. Increased speed and efficiency – Cloud testing can help you get your products to market faster, since you can quickly provision the resources you need and don’t have to wait for new hardware to be delivered and installed.

4. Improved collaboration – Cloud testing platforms make it easy for distributed teams to work together on testing projects, since everyone can access the same resources and data.

8. What are some of the main challenges faced while performing cloud testing?

One of the main challenges faced while performing cloud testing is the lack of visibility into the cloud environment. This can make it difficult to identify potential issues and to determine the root cause of problems. Another challenge is the lack of control over the cloud environment, which can make it difficult to replicate test conditions and to reproduce issues.

9. What’s your opinion regarding the security of sensitive data stored on a cloud platform?

There is no doubt that storing sensitive data on a cloud platform comes with certain risks. However, I believe that these risks can be mitigated through proper security measures. For example, data should be encrypted both in transit and at rest, and access to the data should be strictly controlled. With the right precautions in place, I believe that cloud storage can be a secure option for sensitive data.

10. Is it possible to automate UI tests using a cloud platform? If yes, then how?

Yes, it is possible to automate UI tests using a cloud platform. This can be done by using a cloud-based testing tool, such as Sauce Labs or BrowserStack. These tools allow you to run your tests on a variety of different browsers and devices, all from the cloud. This can be a great way to save time and money on testing, as you do not need to set up and maintain your own testing infrastructure.

11. What are the different deployment models for cloud computing?

The three most common deployment models for cloud computing are public, private, and hybrid. Public clouds are owned and operated by a third-party service provider, and they make their resources available to the general public. Private clouds are owned and operated by a single organization, and they are not made available to the general public. Hybrid clouds are a combination of public and private clouds, and they allow for data and applications to be moved between the two as needed.

12. Do you think that cloud testing will replace traditional software testing? Why or why not?

While cloud testing has a lot of potential, I don’t think it will replace traditional software testing anytime soon. There are still a lot of companies and organizations who are hesitant to move their data and applications to the cloud. Additionally, cloud testing can be expensive and may not be feasible for all budgets.

13. What is the most suitable way of integrating automated test scripts with build jobs on CI servers like Jenkins?

There are a few different ways that you can integrate automated test scripts with build jobs on CI servers like Jenkins. One way is to simply have the test scripts run as part of the build process. Another way is to have the test scripts run in a separate process, but to have the results of the tests automatically reported back to the CI server.

14. What are the differences between public, private, and hybrid clouds?

Public clouds are owned and operated by a third-party service provider, which makes them available to anyone who wants to use them. Private clouds are owned and operated by a single organization, and are not made available to the general public. Hybrid clouds are a combination of public and private clouds, which are connected to each other and can share data and applications.

15. What is your understanding of Infrastructure as a Service (IaaS)?

Infrastructure as a Service is a cloud computing model in which a third-party provider delivers computer infrastructure—typically a platform virtualization environment—as a service. This can include anything from bare-metal servers and storage to complete virtualized networks. Customers can access this infrastructure via the Internet, and they only pay for the resources they use.

16. What are some of the key features provided by IaaS platforms?

IaaS platforms provide a variety of features that can be useful for cloud testing, including the ability to quickly provision and scale virtual resources, pay-as-you-go pricing, and support for a variety of popular programming languages and frameworks.

17. What are some ways to secure an application deployed on a cloud platform?

One way to secure an application deployed on a cloud platform is to use a Virtual Private Network (VPN). A VPN can encrypt communications between the application and the users, making it more difficult for someone to intercept and read the data. Another way to secure an application is to use a firewall to control traffic to and from the application.

18. Which approach is better – building one’s own automation framework or using a third party tool like Selenium Grid?

It depends on the situation. If you have the time and resources to build your own automation framework, then that can be a great option. However, if you are short on time or resources, then using a third party tool like Selenium Grid can be a better option.

19. Is there any risk of vendor lock-in when choosing a particular cloud service provider?

There is always some risk of vendor lock-in when choosing any type of service provider, but this is especially true for cloud service providers. It can be difficult to switch providers once you’re locked in, so it’s important to do your research and choose a provider that you’re confident you’ll be happy with long-term.

20. What are the primary reasons behind the growing popularity of cloud based services?

The primary reasons for the growing popularity of cloud-based services are the flexibility, scalability, and cost-effectiveness that they offer. With cloud-based services, businesses can pay for only the resources that they need, when they need them, and can scale up or down as their needs change. This flexibility and scalability can save businesses a lot of money, as they don’t have to invest in infrastructure that they may not need in the future.
