AI-Code Creates More Testing Work: Adapting to Increased Demand |

AI-Generated Code and Software Testing: What SAP and QA Professionals Need to Know in 2026

Artificial Intelligence (AI) is changing how software is developed, tested, and maintained. AI-powered coding assistants can generate code, suggest improvements, explain complex logic, and help developers complete repetitive programming tasks more efficiently.

However, generating code faster does not automatically mean delivering better software. AI-generated code still needs to be reviewed, tested, secured, and validated against business requirements.

For SAP developers, software testers, Quality Assurance (QA) engineers, and IT professionals, understanding this relationship is becoming an important part of modern software development.

In this guide, we explore how AI-generated code works, why it creates new testing requirements, which tools and techniques QA professionals can use, and how SAP specialists can prepare for AI-assisted development.

What Is AI-Generated Code?

AI-generated code is source code produced with the assistance of artificial intelligence systems. These systems use trained models to interpret instructions, recognize programming patterns, and generate code based on a developer’s requirements.

Instead of writing every line manually, developers can describe a task in natural language and ask an AI coding assistant to produce an initial implementation.

For example, a developer might request a function that validates user input, processes a data structure, or retrieves information from an API. The AI tool can suggest a possible implementation that the developer then reviews and adapts.

How AI Code Generation Works

AI-assisted coding typically follows a series of steps:

1. Understand the requirement: The developer explains the desired functionality in a prompt.

2. Generate code: The AI system proposes code based on the instructions and available context.

3. Review the output: The developer checks syntax, logic, dependencies, and alignment with the requirement.

4. Test the implementation: Automated and manual tests help identify defects and unexpected behaviour.

5. Refine and maintain: The developer corrects issues, improves the implementation, and documents important decisions.

This workflow can accelerate development, but human review remains essential. AI-generated code may contain logical errors, insecure patterns, incorrect assumptions, or dependencies that are unsuitable for the project.

Who Can Benefit From AI-Generated Code?

AI-assisted development can be useful for several IT roles.

• SAP ABAP developers: Generate code suggestions, explore unfamiliar logic, and create initial implementations for review.

• Software developers: Build prototypes, write boilerplate code, and investigate programming problems.

• QA engineers: Generate test ideas, draft test scripts, and identify potential edge cases.

• Automation testers: Develop and maintain automated testing scripts with appropriate review.

• Solution architects: Evaluate implementation approaches and explore technical alternatives.

• IT support professionals: Understand code, troubleshoot errors, and document technical processes.

The benefits depend on the quality of the instructions, the tool being used, the available context, and the professional’s ability to validate the results.

How AI-Generated Code Is Changing Software Testing

Traditional software development already requires testing throughout the development lifecycle. AI-generated code adds another consideration: developers may produce more code in less time, increasing the amount of output that needs to be reviewed and validated.

This does not mean every AI-generated change automatically increases testing effort. The impact depends on the size of the changes, the complexity of the application, the quality of existing tests, and the effectiveness of the development workflow.

Why QA Teams May Face More Testing Work

AI coding assistants can help developers create features and modifications quickly. However, each change may introduce new risks.

QA teams may need to verify whether the code meets requirements, works with existing functionality, handles unusual inputs, and avoids security or performance problems.

For example, an AI assistant might generate a function that works for normal inputs but fails when the input is empty or incorrectly formatted. A basic demonstration may not reveal this issue, but a well-designed test suite can.

The additional work can include:

• Reviewing AI-generated code changes.

• Creating tests for normal and exceptional conditions.

• Checking integration with existing systems.

• Running regression tests.

• Validating access controls and data handling.

• Investigating defects and reproducing failures.

The key challenge is not simply the quantity of code. It is ensuring that every change meets the required quality standards.

Why Human Review Still Matters

AI-generated code should not be accepted without appropriate validation.

A coding assistant may misunderstand a business requirement, use an unsuitable programming pattern, or generate code that appears correct but behaves incorrectly under specific conditions.

Human reviewers should verify:

• Whether the implementation satisfies the original requirement.

• Whether the code follows project standards.

• Whether error handling is appropriate.

• Whether sensitive information is protected.

• Whether the solution introduces unnecessary complexity.

• Whether tests cover important edge cases.

AI can assist with development and review, but accountability for approving and deploying code must remain with the responsible team.

Essential Testing Strategies for AI-Generated Code

A structured testing approach helps teams identify defects before software reaches production.

1. Unit Testing

Unit testing checks individual functions, methods, or components in isolation.

For AI-generated code, unit tests can verify expected outputs, boundary conditions, invalid inputs, and error handling.

For example, if AI generates a function that calculates a discount, testers should check normal discounts, zero values, invalid inputs, and maximum permitted limits.

2. Integration Testing

Integration testing checks whether different components work correctly together.

AI-generated code may interact with databases, APIs, authentication systems, or existing business applications. Integration tests help identify issues that cannot be detected by testing individual components alone.

For SAP applications, this may involve checking data exchange between an ABAP service, an OData endpoint, and a consuming application.

3. Regression Testing

Regression testing verifies that new code changes have not broken existing functionality.

This is especially important when AI tools generate code modifications across several files or suggest changes to established business logic.

Automated regression suites can help teams repeat important checks after each change.

4. Security Testing

AI-generated code can introduce security weaknesses if it uses unsafe input handling, inappropriate permissions, or insecure data access patterns.

Security testing should include checks for input validation, authorization, sensitive information exposure, and relevant application vulnerabilities.

For web applications, teams may use security testing tools alongside code reviews and dependency scanning. SAP environments also require appropriate authorization reviews and checks against the organization’s security standards.

5. Performance Testing

A function may produce the correct result but still perform poorly when processing large amounts of data or serving many users.

Performance testing helps evaluate response times, resource consumption, and behaviour under load.

This is particularly relevant for enterprise applications that process large datasets or support business-critical operations.

AI-Generated Code Testing Tools and Technologies

Different tools support different stages of the software testing lifecycle. The right choice depends on the application, programming language, technical environment, and testing objective.

Selenium

Selenium is widely used for browser automation. QA engineers can use it to automate web application interactions, validate user journeys, and repeat regression tests.

It can be useful when AI-generated code changes the behaviour of a web interface.

Appium

Appium supports automated testing of mobile applications across supported platforms.

It can help QA teams verify navigation, user interactions, and mobile application behaviour after software changes.

Cypress

Cypress supports automated testing for web applications. It is useful for checking application behaviour in browser-based workflows and integrating tests into development pipelines.

Katalon Studio

Katalon Studio provides capabilities for automated testing across supported application types. Teams can use it to create, execute, and maintain tests based on their project requirements.

OWASP ZAP

OWASP ZAP is a security testing tool that can help identify certain web application vulnerabilities. It should be used as part of a broader security testing process rather than as a guarantee that an application is secure.

Important: No single testing tool can verify every aspect of AI-generated code. Teams should combine appropriate automated tests, manual review, security checks, and business-level validation.

AI-Generated Code in SAP: ABAP, S/4HANA, BTP, and Fiori

SAP professionals can apply AI-assisted development principles to enterprise applications, but they must also understand SAP architecture, business processes, development standards, and system-specific constraints.

AI-generated code should be evaluated within the context of the SAP environment where it will run.

SAP ABAP Development

ABAP developers can explore AI assistance for understanding existing code, generating initial code structures, explaining errors, and creating test ideas.

However, generated ABAP must be checked for correct syntax, data handling, performance, authorization requirements, and compatibility with the target SAP system.

Developers working with the ABAP RESTful Application Programming Model (RAP) should also validate service behaviour, entity definitions, business logic, and applicable transactional requirements.

SAP S/4HANA

SAP S/4HANA implementations often involve interconnected business processes and large volumes of business data.

When AI assists with development in an S/4HANA environment, teams should validate business rules, data consistency, integration points, and the impact on existing processes.

Testing should reflect actual business scenarios rather than focusing only on whether the generated code executes successfully.

SAP Business Technology Platform (BTP)

SAP BTP supports the development and integration of enterprise applications and services.

AI-assisted development in a BTP environment may involve APIs, cloud services, application logic, and integrations. Teams should verify authentication, authorization, configuration, error handling, and service compatibility.

SAP Fiori Applications

SAP Fiori applications provide user interfaces for SAP business processes. Changes to application logic or interfaces should be tested for navigation, usability, data validation, accessibility, and correct interaction with backend services.

Browser automation may be useful for selected user journeys, while backend tests and integration tests verify other aspects of the application.

SAP Security and Authorizations

Security is especially important in enterprise environments because applications may handle financial, employee, customer, and operational data.

AI-generated code must be reviewed to ensure that it respects authorization checks, avoids exposing sensitive data, and follows applicable security policies.

Organizations should also ensure that developers use approved AI tools and do not submit confidential source code or business information to unauthorized services.

Common Mistakes to Avoid When Using AI for Coding and Testing

AI tools can be useful, but poor implementation practices can create avoidable problems.

Accepting Generated Code Without Reviewing It

Generated code may contain errors or incorrect assumptions. Developers should review the output and validate it with appropriate tests before merging or deploying it.

Depending Only on Automated Tests

Automated tests are valuable, but they may not cover every business requirement, security risk, or usability issue.

Combine automation with manual exploratory testing, code reviews, and requirement-based validation where appropriate.

Ignoring Edge Cases

Testing only normal scenarios can leave important defects undetected.

Include invalid inputs, empty values, boundary conditions, permission failures, network errors, and other scenarios relevant to the application.

Using AI Without Clear Requirements

Vague prompts often produce incomplete or unsuitable code.

Provide clear requirements, relevant technical context, expected outputs, constraints, and examples when using an AI coding assistant.

Overlooking Security and Confidentiality

Do not assume that AI-generated code is secure. Follow organizational policies for source code, credentials, personal data, and the use of external AI services.

Choosing Tools Without Considering the Project

A tool that works well for browser automation may not be suitable for testing backend business logic. Select tools according to the application architecture and the specific quality risks being addressed.

How to Build Practical Experience With AI-Generated Code Testing

Practical experience helps IT professionals understand how generated code behaves beyond simple demonstrations.

A beginner-friendly learning plan can include the following steps.

Step 1: Learn programming fundamentals. Understand variables, conditions, loops, functions, data structures, and error handling in the language relevant to your role.

Step 2: Practise manual testing. Write test cases, define expected results, execute tests, and document defects.

Step 3: Use AI to generate a small function. Choose a simple task, such as validating an email format or calculating a total.

Step 4: Review and test the output. Check the generated code and test valid inputs, invalid inputs, and edge cases.

Step 5: Automate the tests. Use an appropriate testing framework to execute the checks repeatedly.

Step 6: Explore a realistic project. For web development, this might be a form or API. For SAP professionals, it could involve an appropriate development or training environment.

Step 7: Document your work. Record the requirements, generated code, test cases, defects found, corrections made, and final results.

This approach creates practical evidence of problem-solving ability and helps learners explain their technical decisions during interviews.
