f you were to sit and imagine test cases, maybe the sheer thought of them just sounds formal and complicated… but what if we told you that test cases don't have to be the formal, rigid structures you might be imagining?

At its core, a test case is just a test instruction; a prompt, or an idea of something to check. It's one test out of many that needs to be performed as part of a testing process.

Let's take a fresh look at what test cases really are and how they can be used in a simplified way.

The simple truth about Test Cases

Traditionally, test cases have been seen as formal documents with specific structures.

But let's break free from that mindset for a moment. It doesn't have to be fancy or overly structured. What if a test case could be as simple as just a few words:

• "Check login with valid credentials"
• "Verify email sent on password reset"
• "Test checkout process with multiple items"

These could all be valid test cases. They're clear, concise, and get the job done. As long as your team understands what it means, it could count as a test case.

No lengthy documents required. No need to overcomplicate things.

Test Case structure: From straightforward to complex

The structure of a test case can vary widely, depending on your needs:

• Super Simple: A one-liner that captures the essence of what needs to be tested.
• Basic Structure: A title with some steps and expected outcomes.
• More Detailed: Title, description, preconditions, steps, expected outcomes, and perhaps some metadata like priority or who should perform the test.

You may look at your options and assume the “more detailed” approach is always best. We’d suggest thinking about what you need to test before going down the most structured path, just to make sure you aren’t creating more work for yourself.

Choosing the right structure for your team

So, how do you decide what structure to use? You don’t have to go down the most complex or difficult route. Here are a few things to consider first:

• Team Experience: If your testers are experienced and familiar with the product, they might need less detailed instructions.
• Project Complexity: More complex projects might require more detailed test cases.
• Maintenance: Remember, the more detailed your test cases, the more time-consuming they are to maintain. Ask yourself: when you have 100 test cases, how easy will they be to update?
• Tools: The tools you use can influence your structure. Test Case Management tools often encourage more structured formats, while other tools like spreadsheets or Testpad allow for more flexibility. If you’re just starting out, the simplest tool makes the best option.

Industry standard vs. Pragmatic approach

Many test case management tools and industry standards will push for highly structured test cases with numerous fields. While this can be useful in some contexts, it's not always necessary or even beneficial.

If in your process you’ve accumulated hundreds of test cases, you’re going to have to consider how easy those are to maintain. If each one is more words, and even more complicated, will that be sustainable to maintain in the long run?

A pragamtic approach would be to keep things as simple as possible, even as your project scales. Shorter, more concise test cases or test scripts are often easier to write, read, maintain, and use. They're especially effective when your testers are familiar with the product.

How to write Test Cases

When writing test cases, consider these points:

1. Keep it simple: Start with a list of things you want to remember to test.

2. Iterate: Refine your test cases based on your understanding of the process and the level of detail needed.

3. Consider your audience: If your testers know the product well, you probably don't need to spell out every single step.

4. Think about maintenance: The more words you use, the more you'll have to update later.

Understanding how to use Test Cases

Remember, test cases are just one part of the testing process. They're not about ensuring quality – that's a much bigger topic. Let's put test cases in their proper context:

• Information Gatherers: Test cases help you learn about your product's behavior under specific conditions.
• Decision Aids: The data from test cases informs project decisions and next steps.
• Living Documents: Good test cases evolve with your product.
• Communication Tools: They help convey expected software behavior to the team.
• Structured Exploration: Test cases provide a framework, but shouldn't replace exploratory testing.
• Automation Candidates: Some repetitive test cases might be good for automation.
• Context Dependent: How you write and use test cases should fit your team and project needs.

Remember, the goal isn't to have sheer volume or the most detailed test cases. It's to have the right ones that help you understand your software better and make informed decisions.

Wrapping up

Whether you're using manual testing or automated testing, whether you prefer detailed scripts or simple prompts, the key is to find an approach that works for your team and your project. Don't get bogged down in formalities or industry jargon. Focus on what helps you test effectively and efficiently.

Remember, a test case is just an instruction for testing. Keep it as simple as it can be while still being effective for your team, and you'll be on the right track.
