There are multiple use cases on the application of GenAI
capabilities in the field of software testing. On this article I have focused on very
important use case of improving test coverage using GenAI.
§ Can
GenAI be used to understand a software requirements/User Story?
§ Can
GenAI be used to generate test cases for the given requirement?
§ Can
GenAI improve the test coverage?
For this study, I have used ChatGPT 3.5 as GenAI
platform. I tested this platform by providing a simple User story and prompting
ChatGPT to understand the requirement and generate test cases.
Steps
performed:
1.
Prompted ChatGPT to act like/play the role of a
Software Test Engineer (user prompt 1)
2.
Prompted ChatGPT to list the various points we
need to consider while understanding / analysing a given requirement (user prompt 2)
3.
Prompted ChatCPT to generate test cases based on
a sample user story (user prompt 3)
4.
Gave the same user Story and again asked to
generate test cases to see how it can improve generated test cases over
previous results (user prompt 4)
5.
Prompted ChatGPT to consolidate the previous
results and give me the final list of test cases (user
prompt 5)
Key
findings:
§
GenAI has wide range of use cases when
prompted to act like a Software Test Engineer (Requirement understanding, Test
planning, Test Case Design, Test Execution…etc.,) [Refer
the below response for user prompt 1].
§
GenAI has ability to perform detailed
analysis of a given software requirement. The areas listed by ChatGPT shows
in-depth and extensive understanding/analysis covering various aspects (acceptance
criteria, user roles, dependencies, functional requirements, non-functional requirements,
business rules, data requirements, error handling, performance exceptions,
security, integration points, scalability, regulatory/compliance requirements…etc.,)
[Refer the below response for user prompt 2].
§
GenAI can generate detailed test cases and
improve its results over previous results generations. [Refer the below response for user prompt 3 & 4].
§
GenAI has ability to think out-of-box
scenarios even when the requirement is ambiguous and with unclear acceptance
criteria (Note: sample user story provided to ChatGPT is very simple
requirement but has unclear acceptance criteria and missing explicit
conditions)
§
Final generations of test cases for the given
requirement shows improved test coverage (covering all positive/intended
flows, negative/alternative flows, exceptions). [Refer
the below response for user prompt 5].
§
I have tested this same example with few experienced
test engineers in my team and surprisingly found testers were not able to think
100% of the test cases generated by ChatGPT. The main reason for this is due to ChatGPT’s well-structured
thoughtful requirement analysis and ability to learn & improve over
previous results.
§
I strongly believe GenAI can play key role in helping
test engineers to generate test cases in quick time with extensive test
coverage.
Note: I have used very simple
prompts for simplicity of this study and ChatGPT has ability to provide improved
accurate results based on the good user prompts (clear context, specific
details, reference to previous results, clear expectations)

Response: Sure, I can provide information and guidance on
how a software test engineer typically approaches their job: 1.
Understanding Requirements: As a software
test engineer, one of the first steps is to thoroughly understand the
software requirements and specifications. This involves collaborating with
product managers, developers, and other stakeholders to ensure a clear
understanding of what the software is supposed to do. 2.
Test Planning: Create a detailed test plan that outlines the
scope, objectives, test cases, and testing strategies for the project. This
plan serves as a roadmap for the testing process. 3.
Test Case Design: Design test cases based on the requirements. Test
cases should cover different scenarios, including normal and edge cases, to
ensure comprehensive testing. 4.
Test Environment Setup: Prepare the necessary test
environments, including hardware, software, and data, to replicate the
production environment as closely as possible. 5.
Test Execution: Execute test cases according to the test plan.
This involves interacting with the software, entering test data, and
observing the system's behavior. Automated testing tools may be used to
streamline this process. 6.
Defect Identification: When issues or defects are
found, document them clearly. Provide detailed information, including steps
to reproduce the issue, expected vs. actual results, and any relevant logs or
error messages. 7.
Regression Testing: After defects are fixed, perform regression
testing to ensure that the changes do not introduce new issues and that the
existing functionality still works as expected. 8.
Performance Testing: Conduct performance testing to assess the
software's scalability, responsiveness, and resource utilization under
various load conditions. 9.
Security Testing: Assess the software's security by identifying
vulnerabilities and weaknesses, such as SQL injection, cross-site scripting
(XSS), and authentication issues. 10.
Test Reporting: Generate test reports that summarize the testing
activities, including the number of test cases executed, defects found, and
the overall quality of the software. 11.
Collaboration: Maintain open communication with the development
team to address issues promptly and ensure a smooth testing process. 12.
Continuous Learning: Stay updated with the latest testing techniques,
tools, and industry trends to improve testing processes and effectiveness. 13.
Automation: Explore opportunities for test automation to
increase testing efficiency and repeatability, especially for regression
testing. 14.
Adaptability: Be flexible and adaptable, as software
development methodologies, project requirements, and technologies may change
over time. 15.
Quality Assurance: Ultimately, the goal is to ensure the software
meets high-quality standards and is ready for release to users. Remember that the role of a software test engineer
is crucial in delivering a reliable and bug-free software product to
end-users. Effective testing helps identify and resolve issues early in the
development cycle, saving time and resources in the long run. |

Response: Certainly, analyzing the requirements of a given
user story is a critical step in software development. Here are various
points to consider during this analysis: 1.
User Story Description: Understand the user story's
title and narrative description to get a high-level overview of what the user
wants. 2.
Acceptance Criteria: Review the acceptance criteria, which outline the
specific conditions that must be met for the user story to be considered
complete. These criteria provide detailed requirements. 3.
Functional Requirements: Identify the functional
requirements, which describe what the system or feature should do. Look for
actions, operations, or behaviors that need to be implemented. 4.
Non-Functional Requirements: Consider
non-functional requirements, such as performance, security, usability,
scalability, and reliability. These criteria define how the system should
perform rather than what it should do. 5.
Dependencies: Check if there are any dependencies on other user
stories, features, or components that need to be considered when implementing
this user story. 6.
Business Rules: Understand any business rules or logic that apply
to the user story. These rules may dictate specific workflows, calculations,
or data validations. 7.
Data Requirements: Determine what data the user story interacts
with, whether it involves creating, updating, or retrieving data. Understand
the data sources and data structures involved. 8.
User Roles: Identify the user roles or personas involved in
the user story. Understand how each user role interacts with the system and
what their specific needs are. 9.
User Interface (UI) Considerations: If applicable,
analyze the UI requirements. Look for design elements, layout, and user
interactions needed to fulfill the user story. 10.
Error Handling: Consider how the system should handle errors or
exceptions. Define error messages, recovery processes, and error logging
requirements. 11.
Performance Expectations: Determine any performance
expectations, such as response times, load handling, and resource
utilization. Ensure that the system meets performance requirements. 12.
Security Requirements: Assess security
considerations, including user authentication, data encryption, access
control, and protection against common vulnerabilities. 13.
Integration Points: Identify any external systems, APIs, or services
that the user story needs to interact with. Specify how data will be
exchanged and any integration requirements. 14.
Scalability and Extensibility: Consider whether
the feature needs to scale to accommodate future growth or if it should be
easily extensible to add new functionality later. 15.
Regulatory and Compliance Requirements: Determine if
there are any legal or regulatory requirements that the system must adhere
to, such as GDPR, HIPAA, or industry-specific standards. 16.
User Experience (UX) Guidelines: If applicable,
follow UX guidelines and best practices to ensure that the user story aligns
with a consistent and user-friendly design. 17.
Testing Scenarios: Think about various test scenarios that can be
derived from the requirements to ensure comprehensive testing. Consider both
positive and negative test cases. 18.

that may not be covered in the acceptance criteria but could impact the
user's experience. 19.
Performance Metrics: Define specific performance metrics and key
performance indicators (KPIs) that will be used to measure the success of the
user story. 20.
Feedback Mechanisms: Determine how user feedback will be collected and
incorporated into the user story's implementation and future iterations. 21.
Documentation Requirements: Specify any
documentation that needs to be created, such as user manuals, technical
documentation, or training materials. 22.
Constraints: Consider any constraints or limitations, such as
budget, timeline, or technology stack, that may impact the implementation of
the user story. 23.
Priority: Understand the priority of the user story within
the overall project or product backlog. 24.
Acceptance Test Plan: Develop an acceptance test
plan that outlines the steps and criteria for validating that the user story
meets its requirements. 25.
