Automated Testing

A Guide to Implementing Success-Driven Functional Automation Testing

Reading Time: 15 minutes

Everyone says that automated testing is expensive. Yet, at the same time, you can’t afford not to use it. You certainly should consider the costs involved. But more attention should go to what happens when your project is devoid of automation. So, today, we discuss its application in the most profit-driven area – functional automated testing.

What Is Functional Automation Testing?

Let’s avoid fancy term descriptions and focus on what’s important.

Functional testing means checking whether a product does what it should. For example, when a user clicks “Add to cart,” the app should include the selected item in the personal account. To check this functionality, you open the application, add a product to the cart, and see what happens. That’s how you’ll know whether this feature works.

Functional testing automation follows the same principle. But it uses tools and frameworks to streamline this process. Instead of performing the described action over and over again, you can just create a test script. After that, you’re free to run it whenever and however many times you need.

So, the entire repetition aspect is gone. This means that:

  • Your team isn’t burdened by mundane tasks.
  • Testing itself is much quicker.
  • The results are more accurate as the possibility of human error is gone.

From a technical POV, functional test automation does the same thing as manual checks.

  • Ensures the software aligns with business needs and functional specifications.
  • Confirms it behaves as expected under various conditions (normal and edge cases).
  • Validates end-to-end workflows to ensure all integrated components and processes function correctly together.

But if we’re talking team and business benefits, oh, the differences are astonishing.

Increased efficiency and speed:

  • Functional test automation tools execute checks faster than manual efforts
  • Continuous automated execution translates to faster feedback loops and issue identification.

Accuracy and reliability:

  • Scripts eliminate human errors, ensuring the same steps are performed every time.
  • Consistent results and standardized reports allow for better analysis and decision-making.

Enhanced test coverage:

  • Automation supports testing larger numbers of scenarios in less time.
  • It enables comprehensive functional test coverage across different configurations.

Faster time to market:

  • Reduced testing cycles save time in repeated runs.
  • Parallel test execution allows running multiple cases simultaneously in various environments.

Cost savings (surprise!):

  • Automation handles increased workloads without proportional cost increases.
  • Automated functional testing’s reusability also allows for better planning and reduced manual efforts.
  • Minimized manual labor and improved test reliability translate to long-term expense reduction.

With all that, it’s no wonder that QA functional testing is most often the first candidate for automation. These checks cover critical features and need regular validation. So, there’s no reason not to make functional tests faster and more precise. But, of course, there’s a “but.”

Manual Functional Testing vs Automation Testing

Automated testing strives to fully replace manual checks. And while companies rush after the benefits of automation, they forget about the unique values of manual QA. Even our god and savior, AI, can’t replace it (for now, at least).

So, we do encourage you to use automation for functional testing. But you should keep in mind that you should be careful with it. Because in the current IT era, automated and manual tests serve different purposes.

Let’s break this down.

Functional Manual Software Testing

Most often, manual functional checks are used for working with new or unstable features. You can’t apply automation to them yet. So, manual QA takes center stage here. It’s also the only way to uncover unexpected behaviors and cover extremely complex scenarios.

In these cases, manual QA offers the following perks:

  • It’s easier to adapt to changes or explore edge cases.
  • There’s no need for setup or scripting. You can start testing immediately without investing much.
  • Testing is more user-centric, allowing QA engineers to think and act like real users.

Yet, these advantages come at a price:

  • Executing the same tests repeatedly takes significant time and effort.
  • Mistakes can occur, especially with repetitive tasks.
  • Testing a large number of scenarios or configurations manually is challenging.

And that’s exactly why the use of manual QA should be rather limited. Yes, it gives you what automated testing never can. But it’s also slower and comparatively more error-prone.

Automated Functional Testing

You can use automation for a lot more. But it works best with repetitive checks, such as regression. You can also apply it for large-scale testing, like cross-browser testing. And use it in data-driven testing and CI/CD workflows to streamline development.

Overall, functional automation testing services have many values to offer:

  • It delivers the same results every time, avoiding human errors.
  • You can execute tests much faster and run many of them at once.
  • Automation also reduces costs for repeated testing during development cycles.
  • Plus, it allows your team to focus on other, more complex tasks.

Of course, automated testing isn’t perfect. It also has its drawbacks:

  • Requires time and expertise to write and maintain test scripts.
  • Cannot handle unexpected issues or exploratory testing.
  • Relies on specific tools, which might have limitations or require investment.
  • There’s always the risk of overusing automation. And that could open a huge can of mutated worms.

And that’s exactly why the use of automated QA should be limited (oh, deja vu). But really. Let’s take a look at functional automated UI testing. It could perfectly handle checking the functionality of buttons, links, and forms. Now, let’s step into a user’s shoes for a second.

  • What if they accidentally press “Pay” two times?
  • What if their device crashes while they’re completing an order form?
  • What if they’re using two devices to fulfill the same order?

It’s an anything-can-happen world. And unexpected scenarios are something automation isn’t capable of dealing with. The point is, functional testing needs manual and automation testing. This mix of the two approaches is the difference between a high-quality and an alright project.

How to Use Automated Functional Testing

Automated functional testing services are incredibly versatile. You can apply them in tiny doses or overhaul every one of your processes. But there are some restrictions. They don’t curb automation’s effectiveness but help you avoid resource wasting and quality drops.

For example, some functional testing services can be automated only slightly. Let’s consider exploratory tests. They rely on human creativity and intuition to find odd mistakes (or features) in a product. Yet, some aspects of such randomized discovery can be automated. For instance, you can use AI tools to suggest exploration vectors, generate data, or simulate user interactions.

So, you’re automating a human-driven area to ease a QA engineer’s work, not replace it. The point is that you shouldn’t automate for the sake of automation. It should be applied only where it creates specific benefits. And yes, in some cases, functional automation testing can become a genuine hindrance.

Consider localization testing. You can automate language translation, switching, and text truncation and overlaps. But if we’re talking content appropriateness or cultural sensitivity, that’s a job for manual QA.

Overall, you’re free to automate whatever you want. Yet, you should really consider whether automation in this or that case is beneficial to your project.

From our experience, we can highlight precise characteristics that make scenarios ideal candidates for automation:

Characteristic Description Example
Repetitive or high-frequency execution Scenarios executed repeatedly during development cycles. Regression testing for login functionality after every code update.
High accuracy and precision requirements Scenarios requiring exact validation of specific outputs. Verifying tax or discount calculations in an e-commerce checkout process.
Data-intensive scenarios Tests needing validation against large or varied datasets. Testing form submissions with 100+ combinations of input data.
Predictable and rule-based behavior Scenarios with clear workflows and expected outcomes. Validating mandatory fields and character limits in a user registration form.
Stable functionalities Features unlikely to change frequently, ensuring long-term automation viability. Checking that navigation menu links lead to the correct pages.
Critical business workflows Core application functionalities that must work flawlessly. Testing an order placement workflow from cart to payment and confirmation.
Regression-prone areas Features or modules where bugs often occur after updates. Verifying role-based access control after implementing new features.
Time-consuming manual tests Scenarios involving detailed actions that are labor-intensive manually. Validating multi-step workflows, like onboarding or checkout processes.
Cross-environment functional validation Functional tests needing validation across different environments. Ensuring the “Add to cart” button works on desktop and mobile browsers.

Automated Functional Testing in Agile

Continuing with the theme of using automation correctly, we should mention its role in Agile. For most projects, automated functional testing is certainly optional. But for Agile, it’s mandatory. It’s the practice that enables fast and flexible development.

  • OScripts run right after a code change. And developers immediately know if something is broken.
  • Automated tests are built into the CI/CD pipeline. So, code is tested constantly as it’s being developed. In other words, there are system disruptions.
  • As new features are added, automation makes sure that older parts of the software still work as expected. Hence, it upkeeps product stability.
  • Automation removes the need for repetitive manual tests. And your team can focus on more complex tasks. Simply put, the development speeds up without compromising quality.
  • Automated tests are created before the code and are based on acceptance criteria. They become a shared resource that everyone on the team can use. Developers, QA engineers, and product owners can rely on them to make sure the software meets its goals.

In standard projects, automation can be introduced whenever you want. And you can apply it to any degree you wish – in bits or as a complete overhaul. Automated functional testing in Agile, however, needs to begin simultaneously with the project. Without it, the entire process would fall apart.

  • Introduce automation early. As soon as development begins, consider which tests can be automated.
  • Make sure the scripts align with user stories and acceptance criteria.
  • Integrate automated tests into your CI/CD pipeline to ensure that tests are run automatically whenever new code is committed.
  • Ensure that developers run tests as part of their daily workflow, not as a separate phase.
  • Don’t overcomplicate tests or create too many of them. Targeted and organized scripts will be easier to maintain.
  • Regularly review and update tests to reflect changes in features, user stories, and code.
  • Encourage all agents and stakeholders to collaborate to identify valuable automation areas.
  • Track the success of automation by monitoring metrics like test coverage, pass/fail rates, and time saved.
  • Use this data to make informed decisions about how to improve the automation process.

Overall, if you’re working on an Agile project, functional automation testing isn’t something to consider. It’s something to implement right away.

Implementation Tips & Best Practices for Automated Functional Testing

Now, let’s chat about practices that advance your automated testing no matter the project. Over the years of working with diverse niches and products, our QA engineers have gathered real-world insights. So, the following tips are battle-tested.

  • Set clear goals for your tests, focusing on critical scenarios that matter most. Make sure the goals are measurable (e.g., ensure core functionality works) so you can track success.
  • Choose a functional test automation framework with reusable components, easy configuration, and version control. This will make your tests easier to maintain and scale.
  • Design tests to be small and independent from one another. Ensure they handle errors well and use separate data for each test to avoid conflicts.
  • Generate smart test data that reflects real-world usage. Manage different states for tests and make sure data is cleaned up afterward. Be mindful of security, too.
  • Provide clear, real-time test results. Track trends over time and analyze test failures to spot patterns. Summarize key results for decision-makers to quickly understand test progress.
  • Automate your tests to run as part of the build process. This helps you get quick feedback on code quality and keeps the development process smooth.
  • Regularly review your test code and update documentation. Manage technical debt by optimizing tests and fixing any performance issues that arise.
  • Automation should complement manual testing, not replace it. Manual testing is still needed for exploring new features or complex scenarios that can’t easily be automated.

Most importantly, remember that high-quality functional automation testing needs high-quality skills. So, we’d say that your priority should be assembling or hiring a team that can set up, support, and maintain automated tests consistently.

Choosing Automated Functional Testing Software

Functional test automation tools will be at the core of your strategy and success. And you should take their selection carefully. When choosing your helper software, the priority shouldn’t be good reviews or popularity. Instead, we recommend focusing on the following:

  1. The features of the tool and whether they’re able to cover your needs.
  2. The user-friendliness and learnability of the tool to make sure your team doesn’t suffer when working with it or takes extra time to figure it out.
  3. The ability of the tool to integrate and coexist with your existing workflows.
  4. The scalability and adaptability of the tool when your project changes or grows.

These four aspects should be at the core of your selection process. But, of course, you definitely should read up on the software’s reviews. And you might want to evaluate the community behind it. It could be a simple and quick way to troubleshoot any potential issues.

Functional Test Automation Frameworks

First, you’ll have to choose your framework. It’s basically a manual that tells you how to best apply your automation:

  • How to write and perform tests.
  • The input values you’ll be using.
  • The tools it supports.
  • The tracking and reporting features you can rely on.

Overall, functional test automation frameworks provide you with guidelines and resources. And you can pick one that best suits your project.

  • Data-driven frameworks separate data from test logic. With them, you can write one script and feed it different data instead of writing a new case for every input.
  • Keyword-driven frameworks let you write test cases without needing programming skills. The test script reads action keywords and performs the corresponding operation. For example, instead of writing an entire script, you can select the action you want a tool to perform, like “Click”. The program will recognize the marker and automatically act on it.
  • Behavior-driven development frameworks focus on cross-team collaboration. They prioritize writing scripts in simple, natural language everyone can understand. The point of such frameworks is to give everyone the opportunity to participate in quality-related procedures.
  • Hybrid frameworks combine elements from two or more other testing frameworks. It offers a great deal of flexibility. It also lets you quickly adapt to project changes.

Regarding the last framework, it seems to be the obvious choice. It includes all the good stuff from other frameworks. But you should remember that exactly because of that it’s also more difficult to work with. Plus, every project is unique. And sometimes, such an amalgamation of qualities is redundant.

So, center on what a framework can do for your product specifically. Don’t get lost in what it does overall.

Automated Functional Testing Tools

Now, we’ll take a look at a few tools. They are not arranged in any particular way. These are just some options our team worked with and thinks can be useful. So, treat this list as an opportunity to window shop. Review what functional test automation tools can offer and what to expect from them.
