Cloud Testing

The testing of scalability, reliability and performance of online apps in cloud is known as cloud testing. As compared to old testing environment, cloud testing provides users flexibility, pay-per-usage pricing as well as minimized time to the market. In-built collaboration tools permit geographically disseminated development teams that want to work within the cloud testing setting round-the-clock.

In cloud testing, testers can scale the application assignments to millions of synchronized users in order to search the issues in the performance prior app goes public.

Different Kinds of Cloud Testing:

Cloud testing is categorized in four categories:

1. Whole Cloud Testing - In this, cloud is witnessed as complete entity and the one based on features testing. SaaS and Cloud vendors, and end users are interested in whole cloud testing.

2. Testing in the Cloud - In this testing, every internal feature is checked. It can only be done by cloud vendors.

3. Testing across Cloud - It is done on various cloud types, such as public, private as well as hybrid clouds.

4. SaaS Cloud Testing - SaaS cloud testing is done on basis of application needs. 

It focuses on components like -

- Network - Protocols, various network bandwidths as well as data transfer through networks are covered. 
- Application - It includes functions' testing, data security, end-on business workflows as well as browser compatibility.
- Infrastructure - It includes backups, recovery test, storage policies and secure connection. Infra has to be authenticated for regulatory agreements.

Other Cloud Testing includes:

- Availability
- Performance
- Security
- Multi-tenancy
- Scalability
- Live Upgrade Testing


1. Data Privacy and SecurityCloud apps have multi-tenant nature, so data theft risk is something that always remain. Witnessing this, cloud users are given data safety assurance by service providers.

2. Short Notice PeriodCloud service provider offer one or two weeks' notice period to customers regarding upgrades.  It might be an issue when manually authorize changes in SaaS application.

3. Authorizing Interface CompatibilitySaaS (cloud) subscribers have to make sure that users can select interface version which they want to work for.

4. Data MigrationThis service from a cloud service provider to other is a big challenge for providers having database schemas. Data migration needs plenty of effort in order to understand data fields and how they are mapped in SaaS app.
