Introduction

Imagine you’re developing a mobile app that must work seamlessly across different devices, networks, and scenarios. Now, imagine that app crashing because of unexpected input or a minor glitch. Sounds like a nightmare, doesn’t it? That’s where Robustness Testing comes into play. Robustness testing ensures that software can handle unexpected inputs or conditions without failing, making it a cornerstone of modern software quality assurance.

If you aspire to excel in the field of software testing, enrolling in a QA software testing course like those offered at H2K Infosys can provide the comprehensive training needed to master robustness testing and other essential QA techniques.

What is Robustness testing?

Software has many features that are to be tested under system testing. Hence there are many different types of system testing. It is a huge list with more than 100 different types of testing that can be listed. Robustness testing is a quality assurance testing methodology to test the robustness of the software application. Here the testing is done by giving the invalid inputs. Robustness testing is usually done to test the exceptional handling.

Why is Robustness Testing Important?

  • Error Detection: Identifies vulnerabilities and bugs that might otherwise go unnoticed.
  • User Satisfaction: Ensures a seamless user experience by reducing crashes and unexpected behavior.
  • Regulatory Compliance: Meets industry standards, especially for critical applications like healthcare and finance.
  • Competitive Advantage: Builds trust with users, increasing your software’s marketability.

Example for robustness testing with invalid inputs:

For example, when testing is done for test cases, nominal values are fixed as two variables and change the third value of the variable. Lets say, we will fix the nominal values for X and Y and make the combinations for Z of each value. The nominal values for X and Y are 50 and 40 and we can compare these two values with the given values of Z as 79, 80, 89, 90, 99, 100 and 101. We will fix the nominal values for X and Z as 50, 60 and make the combination with these two values with the given values of Y as 19, 0, 21, 40, 59, 60, 61 and we will fix the value of Y and Z as 40 and 90 and make the combination with value of X as -1, 0, 1, 50, 99, 100, 101. And many test cases will be generated with different combinations.

Robustness testing scenarios:

There are certain scenarios that can cause the failure of software due to lack of robustness of software. The scenarios that can be tested are:

  • invalid inputs
  • interfaces with new software modules or external and independent software
  • changes in environment, sometimes can be a sudden change- hardware of software environment
  • external environment changes affecting the hardware system like magnetic fields, electric fields, pollution etc.

Key Concepts in Robustness Testing

1. Boundary Testing

Boundary testing involves checking the system’s behavior at the edge of input ranges. For example, if a field accepts integers from 1 to 100, boundary testing evaluates inputs like 0, 1, 100, and 101.

2. Fault Injection

Fault injection introduces errors into the system to observe its response. For instance, simulating a network disconnection to test a mobile app’s offline functionality.

3. Stress Testing

Stress testing examines the system’s performance under heavy loads. For example, simulating thousands of concurrent users on an e-commerce website.

4. Fuzz Testing

Fuzz testing uses random or invalid data to test the system’s response. This method is particularly useful for identifying security vulnerabilities.

5. Resilience Testing

Resilience testing ensures that the system can recover quickly from failures. For example, testing a database system’s ability to restore data after a sudden power outage.

Practical Applications of Robustness Testing

Real-World Example: E-Commerce Platforms

An online shopping platform must handle a variety of scenarios, such as:

  • Users entering invalid coupon codes.
  • High traffic during holiday sales.
  • Unexpected payment gateway errors.

Robustness testing ensures the platform doesn’t crash or compromise data integrity under these conditions.

Robustness Testing in Financial Software

Financial applications must be error-free and secure. For instance:

  • Handling incorrect transaction inputs.
  • Managing multiple simultaneous transactions.
  • Preventing data breaches during unexpected system failures.

Robustness Testing for IoT Devices

In the Internet of Things (IoT) ecosystem, robustness testing is vital for:

  • Ensuring reliable communication between devices.
  • Handling unexpected network disruptions.
  • Securing data transmitted between sensors and systems.

How to Perform Robustness Testing

Step 1: Define Test Scenarios

Identify scenarios that could lead to unexpected inputs or conditions.

Step 2: Create Test Cases

Develop detailed test cases for each scenario. For example:

  • Input invalid characters in text fields.
  • Simulate heavy user traffic.
  • Disconnect the system from the internet mid-transaction.

Step 3: Execute Tests

Run the tests in a controlled environment. Use tools like Selenium, JUnit, or Apache JMeter for automation and scalability.

Step 4: Analyze Results

Document system behavior, including errors, crashes, and performance metrics. Use this data to identify areas for improvement.

Step 5: Iterate and Improve

Refine the software based on test results and retest to ensure issues are resolved

Tools for Robustness Testing

  • Selenium: Automates browser-based testing.
  • Apache JMeter: Simulates heavy user loads for performance testing.
  • Postman: Tests APIs for unexpected inputs and responses.
  • Fuzzing Tools: Like AFL (American Fuzzy Lop) for injecting invalid data.
  • Chaos Monkey: Used for resilience testing by introducing random failures in production environments.
