What is SAAS?

AAS stands for “Software as a Service.” The idea behind SaaS is that you don’t

purchase servers and application software and run them in-house. Instead, you

contract with a company with its own server farm, support staff, and software.

Your users then access those applications across the Internet.

What is SAAS Testing?

SaaS Testing refers to the set of testing methodology and processes used to ensure that applications built using the software as a service model of development, functions as designed. SaaS applications entail thorough testing for their integrity, different from that of on-premise applications. This involves testing of data security and privacy, business logic, data integration, performance, interface compatibility, Optimization of testing, and scalability, among others.

Worldwide Software-as-a-Service (SaaS) revenue is expected to reach USD 22.1 billion by 2015 as more companies invest in cloud technology, research firm Gartner said. This increasing demand for SaaS based applications for business is characterized primarily by the following factors:

  • Improved availability
  • Better reliability
  • Need for Quick deployment
  • Reduced internal system dependencies
  • Multi-tenancy
  • Pay-per-usage
  • Higher system accessibility
  • Resource scaling based on needsSo let’s have a look at what needs to be tested for SAAS Applications:
    • Security Testing: In order to avoid unauthorized access to the data and maintain the integrity of the data within a SaaS app, it is important to perform security testing.

    • Performance Testing: Performance is a key element to measure its effectiveness. The performance of the application should be intact from the number of requests comes from the users. Performance testing will ensure that the SaaS application performs efficiently irrespective of the traffic load.

    • Interoperability Testing: Any SaaS application should work seamlessly in all the different platforms and environments and interoperability testing helps you evaluate it.

    • Load and Stress Testing: These methods would help you identify the stability of a specific system or entity. This kind of testing involves testing the application beyond its operational capacity in order to see how it reacts and give results. It is crucial that you conduct load and stress testing to simulate real-life scenarios within a SAAS application.

      Core Components of SAAS Testing:

      • Application
      • Infra structure
      • Network

  • SAAS Upgrades
  • Domain and Business Knowledge
  • Interface Testing
  • Data Security
  • Integrating Enterprise Applications


Common challenges that obstruct SAAS-based application testing:

Although the challenges may differ a bit depending on the type of project, let’s see some common challenges that are experienced while SAAS application testing:

  1. Frequent upgrades and releases in a very short time period provide lesser time to check the validity and security of the applications
  2. Sometimes back-end components that are associated with the user interface of the application are left to be validated
  3. With different user behaviors at the same time, it becomes a very difficult task to take care of privacy and ensure no exchange of customer data
  4. We have discussed why performance testing is required for the SaaS application, but the major concern and challenge in this regard is to identify the most accessed areas and to test them with a large number of users from different locations
  5. At the time of integration and migration of the SaaS applications, it becomes very difficult to maintain the privacy and integrity of the test data
  6. Whenever a new release is made, SaaS testers need to test all the licensing factors including usage, the number of users and functionality of the application
  7. No standardization of the application.

Ways to overcome SAAS Application Testing Challenges

To overcome the above obstructions and enable end-to-end testing of a SAAS-based applications, companies can follow the below mentioned guidelines:

  • Automate scripts to tackle frequent update challenges
  • Based on the observation, determine the areas of the application that are accessed more often. This will help in better performance testing when there is a restriction in the time limit
  • For data security of the SAAS application, strong encryption is recommended at the time of integration.



SAAS applications definitely help non-software organizations to concentrate on their core business areas. It eliminates the effort required to develop, maintain and support software which is not their cup of tea. SaaS makes them to use their resources in a much productive form in their core business areas. A comprehensive testing is necessary so that subscribers can make use of all the benefits offered by SaaS. Organizations must also realize the demand for End-to-End testing on these types of applications. And most importantly organizations who opt for SAAS must realize that they need a testing team which contains not only testers but domain and business experts for carrying out tests with the right strategy.
