Fintech Test Automation with DevAssure | A Step by Step Guide
Software testing is an extremely important process that cannot be skipped for the deployment of fintech products. Since the major use cases revolve around financial transactions and computations, it is essential to ensure that the fintech product or any banking solution or banking application functions seamlessly. In this blog, the focus is around how DevAssure's Automation solution can help improve the quality of fintech and banking products.
What is FinTech testing?
Financial technology or FinTech, refers to the use of technology to provide financial products and services, like online banking, online lending platforms, digital payment system, robo-advisors, and cryptocurrency exchanges. FinTech testing is the process of validating these digital solutions, ensuring their security, reliability and functionality. In order to meet customer expectations and prevent customer churns, its important for testers in FinTech to focus on the accuracy and the functionality of the services being provided. The dynamic nature of FinTech presents unique challenges for quality assurance teams. With FinTech solutions it is important to perform repeated and rigorous tests and cover all possible scenarios during every release cycle.
One of the key challenges with testing FinTech applications is the ability to perform repetitive but essential tests, at a faster rate. Additionally, FinTech applications connect to multiple systems and platforms, and testing these different points of integrations manually is again a challenge and time consuming, thereby slowing down the release cycles. By automating such tasks, companies can identify issues in the development cycle, improve test coverage, and finally go to market faster with higher quality.
What is DevAssure?
DevAssure is one of the best test automation platforms available to automate the test cases in FinTech applications. It is a low code automation tool that enables teams to follow shift left testing, which ensures teams identify bugs early in the development cycle.
Key features in DevAssure for FinTech applications' Test Automation
DevAssure has many key features. Learn more here. In this blog the focus will be on 3 key features which were specifically designed for FinTech applications' Test Automation.
In-built library for complex computations
DevAssure offers a comprehensive set of built-in Maths functions, streamlining complex computations and empowering users to perform calculations effortlessly. This can be used when you would need to compute specific data based on a formula, and compare it against an API response, or validate the UI in the FinTech application.
CSV files read and write libraries
With DevAssure's Library for reading and writing csv files, thousands of data downloaded as CSV from the FinTech Application can be validated for accuracy. Since DevAssure is a low code automation tool, all of these data validations and data transformation validations can be automated within a few minutes.
Visual Regression Testing to validate Dashboards and charts rendered
Visual testing, also known as visual regression testing, focuses on verifying the visual aspects of a web application. It ensures that the UI's appearance remains consistent across different development stages and doesn't suffer unintended changes. DevAssure allows you to compare screenshots captured during test executions with baseline snapshots, highlighting any visual discrepancies. This is specifically useful when validating data visualizations in FinTech Applications.
Validate integration apis to third party services
DevAssure provides an extensive suite of built-in actions and libraries designed to query and validate network logs. This functionality enables seamless validation of external API calls made by the application under test, enhancing test accuracy and simplifying the process of network-related validations.
How it works - Explained with an example
Consider HDFC's home loan EMI calculator - https://www.hdfc.com/home-loan-emi-calculator.
The aim here is to validate the monthly interest value displayed on the page, based on the inputs for Principal, Tenure and Rate of Interest.
Step 1 - Record the flow and validation
Using DevAssure's recorder, the actions to select the values from the slider can be recorded.

Once the recording is done, repetitive actions if any can be extracted as functions, so that the same set of steps can be used across different test cases. This helps make the test automation modular and easy to maintain.

Step 2 - Create functions for calculating monthly interest
DevAssure has predefined libraries for various formula based computations while also providing the ability to format the output based on the application's needs.
Here are a list of the different predefined libraries for computations available within DevAssure -
First, let's create a function to calculate the monthly EMI
- As per the screenshot provided, all you have to do is add the formula
- Define the arguments for the variables provided in the formula along with the data type
- Provide the values for any of the optional fields (Absolute value to be returned, how many decimal points to be truncated in the output, upto how many decimal points should the output be rounded off to)
- For this function, we used the Math Formula and not the Math Formula with Formatting, because we will be creating another function to format the output, so that it can be used as a generic function for all the numerical data that needs to be validated.
The next step is to create a function to format the output based on the requirements
In this case the requirement is to truncate all the decimal points, show the separations between the digits based on IN locale and add a prefix to the output. Here's how you can do it with DevAssure, it's as simple as keying in a few values for the fields provided to format the number.
Similar functions could be created for various other computations as well.
Step 3 - Add an action to visually validate the pie chart
DevAssure requires a reference baseline snapshot corresponding to the test step for executing visual testing. On first execution, DevAssure will generate this baseline snapshot. Subsequent runs will compare against the reference.
