Automatic Test Case Generation: Complete Guide

Before the days of AI, QA used to be a lot different. Take test case creation, for example, you used to spend hours documenting steps manually with the risk of inevitable human mistakes. Fast forward to today, now test case creation can be reduced to minutes, even seconds with the power of AI automation. However, with the rise of AI and ML, new questions arise: how to ensure complete test coverage? Which tool is the best for automatic test case generation? This guide will break down the topic fully without dictating anything so you can make the best choices in your QA efforts.

What is automatic test case generation?

It is no surprise the rise of AI is also affecting the software testing process and your approach to it. According to Testfort, companies using AI in testing reported a 30% reduction in testing costs and a 25% increase in testing efficiency. Test case generation is a huge part of this transformation where you can streamline the process and have a huge cut in your manual efforts.Ā 

So what is automatic test case generation?

Automatic test case generation is the process of using software tools to automatically create test cases based on application requirements, code, or user behaviour. Instead of manually writing each test case, you can now use AI-powered tools to analyse the system and generate testing scenarios automatically, with much less effort.Ā 

A great example of these tools is aqua cloud. In the next section, we will break down the practical process for you.Ā 

How Does Automatic Test Case Generation Work?

As already mentioned, automatic test case generation makes your test planning process faster and more efficient. But what does the practical process look like?Ā 

We will take aqua cloud as our leading tool and explain it from using aquaā€™s perspective. Letā€™s break it down into simple steps so you can see how it can solve your testing challenges:

  1. Provide Your Input
    Start by giving your input requirement to create a test case. With aqua, you can use various formats, including user stories, free-form text, voice input, diagrams, or even screenshots. The options depend on the tool’s capabilities and your creativity.
  2. Give Additional Context
    Depending on the tool and its security measures, aqua may already be trained on your data. If not, you might need to provide extra context for any project-specific details that are crucial for generating accurate test cases.
  3. Set Additional Parameters
    Specify what you want from your test case: positive or negative scenarios, a single test case, or a set of test cases. Alternatively, you can let aqua decide the best approach for you.
  4. Generate Test Case(s)
    Now comes the exciting part. aqua automatically generates your test cases based on the input and context you’ve provided, creating a variety of scenarios for you to test. This happens in a few seconds and is 97% faster compared to the manual creation.
  5. Generate Test Data
    If needed, with aqua, you can also generate test data for the test cases, and again, in a few seconds. This step helps you simulate different conditions without the hassle of manual data entry.
  6. Validate the Output
    Review the generated test cases to ensure they align with your project goals. You can make adjustments, separate steps, or even re-run the generation process if necessary.
  7. Add It to Your Test Plan
    Once you’re satisfied with the test cases, you can easily add them to your test plan and prepare for execution.

Test case generation with AI

The key question is which tool to use to execute these steps effectively. While itā€™s theoretically possible to achieve this with tools like ChatGPT, doing so will raise security concerns and require extra context every time. Why take that risk when you have professional tools like aqua, the first framework that introduced revolutionary AI to the QA world?

With aquaā€™s AI capabilities, you can effortlessly create test cases, requirements, and test data in SECONDS, saving up to 97% of your time. And aqua makes all these happen without compromising data safety and your companyā€™s security policies. With 100% coverage in your testing processes, you eliminate the risk of missing critical scenarios. This 3-click transformation is not aquaā€™s only strength: you get a lot more. The AI Copilot assists you throughout your testing journey, with crucial guidance and insights. Native integration with Capture (1-click bug recording solution) ensures a cohesive workflow. Integrations with automation and project management frameworks like Jira, Azure DevOps, Unixshell, Powershell, etc will ensure smooth data flow across your entire testing lifecycle. Conclusion: youā€™re just a few clicks away from stepping into a completely new software testing world with new test case management software.

Challenges of Automatic Test Case Generation

While automatic generation offers many benefits in test case management, it comes with its own set of challenges. Letā€™s explore some common hurdles you might face:

  • Incomplete Requirements: If your systemā€™s requirements are unclear or incomplete, the generated test cases might miss critical scenarios. For example, if a feature for user authentication lacks details, the tool might not generate tests for edge cases like failed login attempts or password recovery. Now imagine how a solution like aqua cloud will be handy with its ability to create an entire requirement from a voice prompt or short text.
  • High Complexity: Complex systems can be difficult for the tool to understand fully. Imagine a banking application with numerous integrations and workflows. The tool might generate tests that miss critical interactions like transferring funds between different accounts.
  • Overlapping Test Cases: Sometimes, the tool generates overlapping test cases, leading to redundant tests. For instance, if your system has multiple login methods (email, social media, etc.), the tool might create separate tests for each, even when they share the same logic.
  • Lack of Context: Sometimes, automatic tools do not grasp the full context of user interactions. This can lead to scenarios that donā€™t reflect real-world usage. Testing a search feature without considering how users typically query data could be a practical example of this.
  • Data Freshness: Not all tools are created equal. Some tools may lack up-to-date information on the latest technologies and frameworks. For instance, if youā€™re working with a new JavaScript framework, a tool that hasnā€™t been updated may not recognise key features or best practices. This will lead to incomplete or ineffective test scenarios.
  • Maintenance Overhead: As your system evolves, youā€™ll need to keep the test cases updated. This can be challenging, especially if the tool doesnā€™t adapt well to changes. If you add new features, ensuring all related test cases are still valid can become a time-consuming task.

That is why you can not just rely on any tool that offers automation. You should be selective and choose the one that minimises the risk of facing the above-mentioned challenges (in other words, aqua cloud).Ā 

Ever wondered how much faster AI really is at generating test cases compared to manual testing? Pick a testing scenario below and watch our live race unfold – you’ll see exactly why AI can deliver 97% time savings and catch way more edge cases than traditional methods.

I have a friend solo developer, who's very good at using AI in his code. He doesn't just ask it for boilerplate code - he discusses with the AI the technologies and the architecture, and then asks it to generate actual, meaningful code - and, case in point, test cases. He doesn't just ask and do - it's a back-and-forth process he uses of giving it a task, then giving it feedback, asking it to improve, etc.
