5 Key Consideration Of Cloud Testing

2019-11-26 by Claire Mackerras

Cloud applications - What comes to your mind first when you heard about the cloud applications? Well, non-technical people think that cloud applications are just a little advanced to traditional web applications. In fact, cloud applications that are developed on the cloud or those applications that are designed for the cloud are entirely different from the traditional web applications.


If we talk about the advantages of cloud applications, they are not only cost-effective but also rich in terms of accessibility and scalability. Most importantly, these applications are developed by keeping modern technologies in mind, such as CSS3, HTML5, jQuery, and JavaScript.


Furthermore, cloud applications must consist of features like Multi-Tenancy, highly configurable, secure, and fault-tolerant. All these features significantly contribute to the growth of the business. By reading the above-mentioned features and functionalities of cloud applications, I hope now you can understand that testing cloud applications are entirely different from testing traditional web applications.


If we talk about the process of cloud testing, it includes the verification of applications with data business workflows, compliance, network/application security, performance, scalability, and compatibility to develop robust applications. Different from progressive web app testing, cloud testing remains moderately steady in terms of versioning, server installation, and multi-platform testing. The critical focus of cloud testing includes several factors, such as security, SLA adherence, deployment, access, and more.


Today in this post, I will suggest five key considerations that software testers cannot ignore while testing cloud applications.


Performance Testing

Do you know that cloud applications run on shared hardware on which testers have no control? In this scenario, performance testing and scalability of the applications become a head honcho. Sometimes, running load tests of the applications and shared resources can impact the performance of the app so, it is very crucial to evaluate the performance of the apps during testing.


Furthermore, software testers also need to evaluate response times, latency, response codes, errors, deviations, and some other isolate issues so that an increasing number of users cannot affect the overall performance of the application. Also, they need to pay attention to the number of concurrent users accessing the application from different geo-locations.



Security Testing

As we have mentioned earlier, that cloud applications run on shared hardware and resources so, software testers need to pay attention to the security parameters of testing to make sure data integrity and security. Moreover, software testers also need to execute security testing in terms of SQL injections, testing cookies, cross-site scripting, and multi-tenant isolation.


Apart from this, they also need to approach accessibility concerns by doing multi-privilege tests and access control tests to make sure that one's tenant's data is safe and confidential. Most importantly, software testers should not forget network testing to manage access, sensitive data flow, and encryption.


Third-Party Dependencies

The next crucial thing that testers need to focus on is to test third-party dependencies. Most of the time, testers need to use external API's and services to implement such kind of functionalities. Thus, software testers need to test and monitor these external API's to make sure that the app is functioning well.



When testers operate in internal infrastructure, several quantities contribute to the app configuration. The app configuration depends upon factors like bare metal, versions of operating systems, software versions, and COTS software. Apart from this, there are some cases where the app works differently.



Along with the understanding of details of a recognized infrastructure, the app connectivity needs validation. Conversely, Enterprise software solutions can be hosted across alternate cloud providers. Moreover, the connectivity and integration demand to be validated not only for the sake of data integrity and completeness but also for resilience and performance.



By reading the considerations mentioned above, I hope you can understand the importance of a software tester and what things you need to keep in mind when it comes to cloud testing. However, software testing is a vast field, but still, these considerations will help you with the best results.
