Understanding Software Testing as a Service over Cloud in Detail

Introduction to Cloud Computing

Cloud computing is an on-demand or pay-as-per-use availability of hardware and software resources. Cloud computing can be considered as a small shared pool that is made up of two words. Cloud: is a vast space to store data, and computing: is the use of computers.

Cloud Computing Models

SaaS(Software-as-a-Service):

These are on-demand applications. We do not own these services but can use them as per our needs against some amount. 

Example: Google mail and Google Drive 

PaaS(Platform-as-a-Service):

It provides a working environment for users to develop applications. With PaaS, users have the flexibility to take advantage of development and deployment tools without installing them on the premises.

Example: force.com.

IaaS(Infrastructure-as-a-Service):

This includes PaaS and SaaS services and some additional cloud services. With an add-on, the user is provided with the underlying operating system, servers, security, and networking for developing applications under this service.

Examples: Microsoft Azure and Amazon web services

Types of Clouds:

There are mainly 4 types of clouds:

Public:

This Cloud is given by third parties cloud service providers and is available to everyone.

Example: Microsoft Azure

Private:

In the Private Cloud, the cloud service providers are enterprise-specific. Data held in the private Cloud can only be shared among specific departments within the organization.

Example: Oracle’s Private Cloud Appliance

Hybrid:

These combine public and private clouds, also known as heterogeneous clouds.

Example: Ensono and DataCore Software

Community:

Cloud service providers can provide services to similar types of companies.

Example: Media industry and Healthcare industry

Software Testing as a Service over Cloud

Cloud testing is a process of testing resources using third-party service providers. Generally, software testing over clouds is carried out through the following steps:

• Creating different scenarios for the user

• Design the test case as per the requirement

• Select the cloud services provider

• Create Infrastructure

• Apply testing to the application

• Tracking goals and observations

• Delivery of the module

Types of Software Testing as a Service over Cloud

Functional:

In this SaaS testing, features of the applications are tested concerning software requirements and the end users’ expectations. This testing includes integration testing, acceptance, and system testing.

Security:

This testing is performed by third-party auditors, which protects cloud infrastructure from loopholes and vulnerabilities that might arise from data breaches.

Performance:

This testing ensures the entire system’s stability in terms of workload and traffic. Performance tests incorporate speed checks, robustness, and application size.

Native:

This testing helps create and amplify and optimize existing cloud applications and gives ways to develop new ones. Cloud-native SaaS testing helps reduce cost, faster release, enhance scalability, and make it easy to manage.

Endurance:

As the name implies, endurance testing tests the application’s robustness and strength with loads. This Testing helps find memory leaks and sustainability regarding application response time.

Latency:

Latency is simply the delay between the requests and responses. This delay should be as less as possible. Latency testing helps the user find the points responsible for increasing uncertainty.
