Guide to Successful AI/ML System Testing

With the development of artificial intelligence and machine learning (AI/ML) based systems in recent years, our interaction with smart appliances such as smart speakers, self-driving automobiles, and so on has increased. And the invasion grows rapidly with each passing year. According to Markets & Markets, the worldwide AI market will grow from USD 58.3 billion in 2021 to USD 309.6 billion by 2026, representing a 39.7 percent effective CAGR during the forecast period.

Artificial intelligence and machine learning algorithms have become more widely used technology in high-stake industries like healthcare, finance, and automobile manufacturing. As a result, the implementation of AI/ML has sporadically grown in these industry-specific applications.

How does Artificial Intelligence Benefit Software Testing?


AI has roots everywhere, which is why it is critical to test these AI/ML-driven apps in order to achieve higher operational efficiency, product iteration, and data security. It is crucial to focus on the problems, critical areas, and significant factors involved in effectively secured testing of AI/ML-based systems.

Critical Areas to Consider While Testing AI-based Systems

Data is the new code for AI-based systems. As a result, in order to have an effective operating system, these solutions must be validated for any changes in input data. This is somehow comparable to the traditional testing approach, in which any modifications to the code result in testing the improved code.

There are a few things to take into account when reviewing AI-based solutions:

Curation of semi-automated training data sets: The semi-automated tailored training data sets incorporate the input data and desired output data. Annotating data sources and features, which is a critical component for migration and deletion, requires static data dependency analysis.

Developing the test data sets: To verify the efficacy of trained models, test data sets are rationally designed to test all potential permutations and combinations. The model is refined throughout training as the number of observations and data variety grows.

Developing test suites for system validation: System validation test suites are generated using the test data sets and algorithms. For instance, in a test case, an AI/ML implemented healthcare system designed to predict a patient outcome based on clinical information should also include patient demography, medical therapy, risk profiling of patient’s disease as well as other required data for the test case.

Reporting the test results: Since ML-based algorithm validation produces range-based precision (confidence ratings) rather than anticipated benefits, test results must be expressed statistically. Testers must define and specify assurance criteria within a relevant interval for each iteration.

Challenges Involved while Testing AI & ML Systems

Proper Training Data: It is estimated that almost 80 percent of scientists’ time goes on creating training datasets for ML models. As these systems highly depend upon labeled data.

Hard to Determine: AI and machine learning systems frequently exhibit disparate actions in response to the same information. They are more likely non-deterministic.

Bias: The training data are often distributed from a single source which can lead to bias.

Ability to Explain: When it comes to extracting certain attributes, the challenge level is enormous. Finding out what led a system to incorrectly detect a picture of a coupe as a sedan, for example, may be impossible.

Continuous Testing: Once a traditional system is tested and validated, it doesn’t require further testing unless a modification has been done to the system. Whereas, the AI/ML-based system, on the other hand, constantly learn, adapt, and train with the new inputs.

Key Aspects of AI & ML System Testing

Curation and Validation of Data

The performance of an AI system is determined by the richness of training data, which includes factors such as bias and variety. Understanding diverse accents are difficult for car navigation systems and phone voice assistants. Like the accent of a Japanese person and an Australian individual can be completely different and difficult to interpret by an AI/ML system. This means that data training is essential for AI systems to get accurate input.

Extensive Performance and Security Testing

QA for AI systems, like any other software platform, causes extensive performance and security testing, along with regulatory compliance testing. Without adequate AI testing, unique security issues such as chatbot manipulation and utilizing speech recordings to mislead voice recognition software are becoming a widespread practice.

Performing Algorithm Testing

Algorithms are the core of an AI system that can process huge chunks of data and provide great insight. The key benefits of this method are model validation, learnability (a great example would be e-commerce sites like Amazon), algorithm efficiency, and real-world sensor detection.

A reliable AI testing approach should thoroughly investigate model validation, efficient learnability, and algorithm efficacy. Any errors in the algorithm may have far-reaching consequences in the future.

Smart Systems Integration Testing

When testing artificial intelligence systems, it is important to keep in mind that AI computers are designed to connect to other systems and solve problems in a much bigger context. During AI testing, a full assessment of the AI system, including its many connection points, is required for seamless, functioning integrations.


When deploying an AI/ML model into production, the number of factors that must be examined vary dramatically from standard software testing approaches. AI/ML-based systems must be updated on a regular basis in order to focus on the data that is fed into the system and the predictive outcomes that are generated.

As more and more businesses start implementing AI in their systems and applications, the testing approaches and procedures will automatically evolve and will ultimately reach the stage of maturity and standardization of traditional testing models.
