Imagine you are constructing a castle in the sky, before letting people into the castle, you would comb through the entire castle to make sure everything is in order. For that, allow me to introduce SaaS testing as something that can be spoken of as dragons that search the whole area of the castle you want to make safe, resistant, and pleasing to any person who is going to visit it.

In other words, SaaS testing means your software is near its optimal condition before you release it to the public. They are about hitting buttons, typing words, and just pointing to see if there is something that will fail. As much as anyone would desire to have a perfect castle, ready to host everyone, SaaS app testing makes sure that the software is perfect before their audience sees it. 

What is SaaS Testing?

The SaaS (Software as a Service) model is rapidly becoming one of the most used methods of application delivery, providing unprecedented flexibility for both small and large enterprises. SaaS platforms play a significant role in this by providing a variety of cloud-based services while also maintaining software quality through various validation processes. Such testing eliminates risks and ensures that the SaaS application is secure, stable, and works appropriately under several conditions.

In a survey, it has been revealed that 85% of organizations use at least one SaaS application, and 75% of them face downtime or failure in the SaaS applications at least once a month.

However, due to the current complex and advanced evolution of web applications, the main focus is on the quality of SaaS-based application testing. The goal of this article will be to identify the limitations of SaaS testing, and the types of testing approached while SaaS software testing. We will also look at the pros of manual and automated testing for SaaS businesses, and how to ensure SaaS software stability to meet the changing business requirements.

  • They allow the developers to evaluate the SaaS application’s ability to handle increased loads and numerous concurrent users.
  • Make sure that there is the capacity to support many users and traffic in the SaaS application.
  • Get rid of application bottlenecks and prepare the application for further scalability as soon as possible.
  • Gatling’s GUI can be used effectively to create and execute load tests effortlessly.
  • It is important to have automated performance testing since it will help in the delivery of consistent and dependable results.

SaaS Testing Approach for Every SaaS Company

Companies focusing on the SaaS segment implement a SaaS testing strategy specific to their needs; this way, problems can be predicted and prevented before they cause significant disruption to customers and decreased quality of developed applications.

Unit testing and Integration testing

This means that unit testing and integration testing are critical for instance for ascertaining the correctness of individual units of code and how well they integrate in the larger framework. This form refers to the process whereby sub-systems are first developed and then combined with a view of testing their coherent recognition.

UI Testing and Functional Testing

Usability testing is done in conjunction with functional testing in order to be certain that the gestures sense and look as they should. This is done by inputting test data and then verifying results obtained from the user interface and individual features or controls.

API Testing and Performance Testing

Both API test and performance tests are applied to ascertain the functionality and to make sure that the APIs are expandable. This type of strategy aims at conducting load and stress testing of APIs in an effort to ascertain their capability to cope with high traffic and loads normally experienced at a particular time.

Security & Vulnerability Testing

Security and vulnerability testing or sometimes referred to as Penetration testing is important in the safeguarding of SaaS applications. This is done through checks for exposure and risk to the overall security of the applications.

As a SaaS application, it is crucial to implement robust security strategies to protect sensitive data and prevent unauthorized access. Learn how SaaS security testing strategies, help you to secure your SaaS application.

Aspects of SaaS testing strategy

Key areas to be addressed in the SaaS testing strategy should include test data management, and automated testing since these will address functional, performance, and security. Secondly, the strategy should include testing for the ability to scale the application and its reliability, because the point of the application is to be easily accessible to the general public.

Aspects of SaaS testing strategy

Understanding Requirements

First, lay down the specifications of the SaaS application which would include; its features, its performance, security, and compliance standards. For the comprehensive strategy, we need to follow this step:

  1. Collaborate with stakeholders
  2. Review product documentation
  3. Conduct interviews
  4. Analyze user stories
  5. Identify testing scope and boundaries
  6. Prioritize testing
  7. Review and refine requirements

Following requirements should considered in SaaS testing:

  • Performance requirements: Test the product's performance, including response time, throughput, and resource utilization.
  • Security requirements: Test the product's security features, including authentication, authorization, and data encryption.
  • Compliance requirements: Test the product's compliance with industry regulations, standards, and best practices.

Creating Test Cases

Generate full-grown operational scenarios for each noted case based on input data, outcome, as well as acceptance factors. It helps to include both the test that you expect to pass and the test you expect to fail in order to verify the expected behavior and possible errors.

Here’s an example of a test case:

Test Cases Examples
Test Case ID TC001
Test Case Description Verify that the login functionality correctly authenticates users with valid credentials.
Preconditions The user has not logged in before.
Input Data Valid username and password.
Expected Outcome The user is successfully logged in and redirected to the dashboard.
Acceptance Criteria The login functionality correctly authenticates users with valid credentials.

Test Steps:

  1. Open the login page
  2. Enter a valid username and password
  3. Click the login button
  4. Verify that the user is redirected to the dashboard

Expected Results: The user is successfully logged in and redirected to the dashboard.

Test Data: Valid username and password.

Test Environment: Desktop browser with internet connection.

Test Case Priority: High

Selecting Testing Tools

In choosing the testing tools and frameworks for a SaaS application, one should consider the technology stack, the testing type, tool complexity and cost, interoperation and extensibility, and support.
