What is Cloud Testing?
Cloud testing is defined as a Software Testing type that’s check Cloud Computing services. Cloud computing is an internet-based platform that renders various computing services like hardware, software and other computer related services remotely. There are three models of Cloud Computing.
- SaaS- Software as a service
- PaaS- Platform as a service
- IaaS- Infrastructure as a service
In the tutorial, we will learn-
- Type of Testing in Cloud
- How to do Cloud Testing
- Example Test cases for Cloud Testing
- Challenges in Cloud Testing
- Cloud Testing Vs Conventional Testing
The whole cloud testing is segmented into four main categories
- Testing of the whole cloud: The cloud is viewed as a whole entity and based on its features testing is carried out. Cloud and SaaS vendors, as well as end users, are interested in carrying out this type of testing
- Testing within a cloud: By checking each of its internal features, testing is carried out. Only cloud vendors can perform this type of testing
- Testing across cloud: Testing is carried out on different types of cloud-like private, public and hybrid clouds
- SaaS testing in cloud: Functional and non-functional testing is carried out on the basis of application requirements
Cloud testing focuses on the core components like
- Application: It covers testing of functions, end-to-end business workflows, data security, browser compatibility, etc.
- Network: It includes testing various network bandwidths, protocols and successful transfer of data through networks.
- Infrastructure: It covers disaster recovery test, backups, secure connection, and storage policies. The infrastructure needs to be validated for regulatory compliances
Other Testing types in Cloud includes
- Live upgrade testing
|Types of Cloud Testing|
||This type of testing is usually performed by cloud or SaaS vendors. The primary objective is to assure the quality of the provided service functions offered in a cloud or a SaaS program. Testing performed in this environment is integration, functional, security, unit, system function validation and Regression Testing as well as performance and scalability evaluation.|
||Online application vendors perform this testing that checks performance and Functional Testing of the cloud-based services. When applications are connected with legacy systems, the quality of the connectivity between the legacy system and under test application on a cloud is validated.|
||To check the quality of a cloud-based application across different clouds this type of testing is performed.|

Challenge#1: Data Security and Privacy
Cloud applications being a multi-tenant in nature, risk of data theft is always remain. As a cloud testing strategy, users should be given an assurance about the safety of their data by suppliers.
Challenge#2: Short notice period
Cloud provider give a short notice period of (1-2 weeks) to the existing customers about upgrades. This is a big problem when manually validating the changes to your SaaS application.
Challenge#3: Validating interface compatibility
With an upgrade in Cloud service provider, at times the external interface is also upgraded which is a challenge for some subscribers who are used to the older interface. Cloud(SaaS) subscribers need to ensure that the users can choose the interface version they wanted to work
Challenge#4: Data Migration
Data migration from one Cloud provider to another is a huge challenge as both providers may have different database schemas and it requires a lot of effort to understand the data fields, relationships and how are they mapped across SaaS application
Challenge#5: Enterprise Application Integration
Enterprise application integration requires data integration validation of both outbound and inbound data, from client network to SaaS application and vice versa. Data privacy calls for a thorough validation in order to ensure SaaS subscribers about security and privacy of data.
Challenge#6: Simulating live upgrade testing
Cloud testing's biggest challenge is to ensure that live upgrades do not impact the existing connected SaaS users
