Test Automation Best Practices and Tips for QA Managers

In the earlier days of software test automation, I was working with two teams at Simform. Both the teams were trying their best to set up and implement the test cases as meticulously as planned. But I realized that one of the groups was following a set of practices that led them to use minimal time and effort with more accurate results. 

The reason behind the performing team was, they knew that relying heavily on one practice will not work, such as record and playback. They went into the details of gauging the exact requirement and avoided unforeseen complexities that non-performing team did not bother to look into.

Later on, we realized that it was these practices that set them apart and made them a distinct team in our organization. We documented their practices and paved our way for the other QA engineers to learn and be the best.

Today, I am sharing a part of it with you all so you can start test automation and make the most out of it.

Let’s begin!

#1. Establishing Test Automation Architecture

Establishing test automation architecture requires thorough planning and estimating capabilities. You need to closely monitor the journey with a detailed roadmap from start to finish. However, if you are new to the concept of integrating test automation in your applications, here’s my two cents: Patience is key!

To bring about substantial results with this approach, I recommend you to evaluate the testing methods implemented to your applications before you focus on long-term goals – Return on Investment (ROI). This approach streamlines distinct features in your agile methodology, making the exercise insightful.

To begin with, let’s find out the significance of executing test automation in your organization.

Every organization wants to convert its 2-hour long cross-browser testing in just 2 minutes, and of course, we want to stay in the competition and deliver high-quality software products within the given deadlines. Besides, you don’t want to lose clients because of testing loopholes.

To shorten this process, here are some key aspects to consider while carrying out test automation:

  • Exploratory Testing: Users are not likely to follow a predefined pattern while using software; their paths are undetermined and critical for which the human thought process is required to understand and test. So this technique is not advisable to automate. QA experts at Simform perform exploratory testing manually rather than automating it. 
  • User Experience: How can we expect a machine or a program to feel like us? Humans are most subjected to emotions and expressions. You need a human to test the usability of your software because it is all about how they feel about your application.
  • App Accessibility: Features in an app need to be discoverable and understandable to ensure users make the most of it. Allowing test automation to check such rates is not realistic. Humans are prone to experience and feel the difficulties in locating features all through the application. 
  • Dynamic Content: With test automation, it can be challenging to understand the state of the content at the time of the test run. It can be anything based on a user’s preferences, i.e., PDF document, text doc, and more. Consider dynamic content testing while bifurcating automated testing. 

#2. QA Best Practices

Each test is distinct in terms of results. Tests with predictable results are useful to automate, while those with random output are kept for manual testing. Experienced software quality engineers understand the consequence of planning test cases and setting priorities. 

To curate the best user experience, you need to understand a user’s behavior closely. 

As said by Alexander Andelkovic, Senior Agile Testing Lead at King, “people usually don’t go back to play a level that they’ve already passed so getting it right the first time is better for the player experience.” – source

He further explains that they developed a bot – created with an advanced neural network – to perform as real players and optimize the feedback loop. With testing automation, they were able to test new releases with a bot, accelerating the feedback circuit. Earlier, with the manual approach, it was challenging to develop the next level, depending on the users’ method for the previous levels.

We all use test automation to save time and achieve deliverables faster. All it demands is proper prioritization, planning an automated test plan, and understanding of the tech stack. For instance, giving high priority to repetitive test cases and regression tests can save you a considerable amount of time.

Another such example is continuous testing, Leo Laskin, Test Automation Advisor at Saucelabs suggests: 

“Don’t ever stop testing. Having tests run on every commit is going to provide significantly higher confidence in your software.” (source)

You can also tell your QA team to get habituated with the best practices in test automation by determining the type of test cases and referring to automated test cases examples. For example, the QA team may sometimes fall short by giving inappropriate tests to the automation. 

Such as the flaky tests. The possible outcomes of the tests are not determined in this format. They are more about under deterministic situations.

These test cases are unnecessary since developers would not know the result of the test. And automating them would make a perfect set of results ensuite. So the priority of such test cases is not at the top of the automation test cases.

#3. Continuous Integration & Test Automation

Creating the zero bugs environment is a bliss! And this is possible through continuous integration.

The earlier you detect, the earlier you get cured. 

You get significant benefits by integrating test automation in the CI environment. Developers can get faster feedback every time they update versions/make changes and can improve their code quality.

Try to draw your developers’ attention by showing them results and see the difference! 

The Co-founder of Agile Testing Fellowship, Janet Gregory, quoted:

“People always say “code and then test,” I prefer “test and then code.”

Continuous integration in itself is very good at smoothing the communication and says goodbye to long waiting times for code to be deployed. Test automation is the cherry on the top when you have CI. It gives the fastest feedback to the developers about quality, functional errors, dependability of features, and more.

It also reduces the efforts required for large merges and last minute conflicts that turn out to be bad customer experience for the clients. It enhances the overall experience of software development and keeps builds ‘bug-free’.

Major Takeaway: Do you know what’s a common thing between Google, ThoughtWorks, Microsoft, and Mozilla? Test automation accounts for more than 50 percent of their total testing efforts. 

#4. Designing the Test Case

Designing the test cases is predominant with test automation. When built from the end-user perspective, a test case is always winning and the most accurate. It focuses more on features than the implementation.

It includes everything starting from a user’s most attended paths to rarely visited. Anyone from your QA team with a knack of knowing risk factors and how they affect end-users can design an appropriate test case.

As quoted in the below tweet:

Designing test cases include factors like test environment management, following the right order of testing modules, and setting the proper time limit for UI elements to appear in the testing automation software.

#5. UI Resistant Automated Tests

During the early days of test automation, we faced significant changes in our test automation plans. It was due to changes in the user interface when the software is in the early stages of development.

It frustrated many of our team members. And hence, we decided to find a solution so that these changes do not affect our test results, i.e., variation in the test results going forward with future versions of the application because of the changes in UI.

To overcome this problem, you have to reverse engineer the process of how automated software identifies the objects. In general, they recognize the objects by location coordinates.

If you can give the permanent unique names to controls, the automated testing software finds it easy to run the tests successfully. And it does not require changing names every time you run the tests.

So yes, this is among the top-notch test automation best practices to test automation for us, and you shouldn’t miss trying!

#6. Regression Test Best Practices

Regression test best practices

Any testing methodology is incomplete without regression tests, and it outlines the picture of how your development efforts are progressing. When you perform test automation in your organization, you must ensure arranging the regression in higher precedence because prioritization plays a crucial role when you organize the process as a whole. 

As said by Federico Toledo in the below quote, implement an optimization that cures the bottleneck. 

“Any optimization that is not about the bottleneck is an illusion of improvement” – Federico Toledo, COO, AbstractaUS.

Regression test is primarily divided into three parts:

  • Smoke tests

Ensures the basic functionality of modules once the new build is ready after the application under test. So the testers should learn to prioritize the double-checking of basic functions to ensure smooth deploy.

  • Sanity tests

If you are establishing test automation at your workplace, your tests must include checking the critical functions of the application because this is where the end-user may struggle, provided the tests are not well-prioritized.

  • Building a sequence of successful test cases 

The best way to do regression is, craft a test case that uncovers most defects and includes a successful test case in your regression test suite, too. You should follow such automated regression testing best practices that teach maintainable tests.

Creating more independent test cases is the key to reduce complex maintenance and is easier to understand for anyone. You can still reuse the code by creating a separate module instead of copy-pasting the test code. We, at Simform, have experienced several tried and tested methods to justify the best regression test practice and techniques.   

#7. Operational Know-how

Before you decide to get test automation at your workplace, you should know the operational know-how well because this is where most of the firms lack.

It includes hiring experienced QA engineers who have the required skills that can get the maximized outcome in less time.

Also, do not just rush for the best-automated testing software in the market. Understand how your project requirements in the usual scenario have been so far? Which test automation framework will you need to configure?

Linde Group converted its challenges into success stories with test automation best practices, here’s how:

Linde Group decided to bring in the digital transformation and adopted it to test automation by all means. Earlier, they were dealing with the legacy software testing system and tools, and by not automating the system, it was difficult for them to handle 100+ applications with frequent updates, and testing along with the SAP software updates. 

They hired test automation experts, who successfully converted challenges into success stories. 

Here’s what Linde’s Head of Service and Security Management, Andreas Aigner, has to say about Test Automation: 

“We couldn’t just speed up our existing QA approach—we had to fundamentally change it. To satisfy expectations of increased application coverage with greater speed but lower costs, we had to simplify testing dramatically. We partnered with Tricentis to establish a new testing approach that enabled everyone from developers to business users to automate testing for everything from SAP, Salesforce, to mobile apps.” – Source

Choose the automated software that possesses the key functionalities of your application. Also, the same applies for the QA team to write scripts that don’t break easily while running the tests. 

#8. Identify Slow & Failing Tests

You should identify the tests that continuously fail or take time. Find solutions to recognize and resolve such assignments that lag and don’t deliver faster results.

Let me share my experience with several projects I have been working at Simform.

In spite of parallelizing the selenium tests, we used to find them slow and couldn’t bear such longer waiting time cumulatively.

What our learning practices made us do?

We added a timer to our test runs that highlighted tests which notably ran slow. We accumulated reports of active tests and other logs from the framework and refactored activities for these tests. Gradually, we started seeing the success. You can also begin learning selenium test automation best practices by referring to this blog.

#9. Automation of Test Cases: Do It Right!

To best organize a team for an organization, you need to run the math that executes the best management with minimal resources. 

The same applies to test automation management. Implement test automation in a way that requires minimal maintenance while producing excellent outcomes. 

  • Document your test case well. A well-written test case is more likely to be well-executed with no test failures. Once you practice documenting a test case, it is more likely that your team has expertise in automating the tests. 
  • No to complicated and flaky tests. Allow your test case to check the single function and deliver the result. You can always break the test cases into two. 
  • Parallel execution is the key to quality software development. You need to parallelize the automated test cases that require no interdependencies. For example, a test case result of a transaction page should not wait or depend on the previous test case, i.e., items in the cart. A strictly followed modular approach creates a win-win situation for test automation and SDLC.
  • You can always group your test cases. Who doesn’t want to reuse the test code? Reusability is best utilized when you know how to arrange the test cases by their functionalities. Specific test automation tools allow us to store user code methods for reusability. It not only spares the additional hours but also enhances the software quality by allowing partial regression tests of the shared functional area.

  • Put the application through tests under stable servers and network connections. Avoid unexpected failures and elements that eat time. Mock servers are the answer to such failure reporting elements.

There are, of course, endless parameters and practices that can help you achieve expertise in test automation. The strategies above, however, are tried and tested to create a base for perfection in automating test architecture. 

Conclusion

I have seen organizations struggling to get their peak on adopting new approaches. They depend on individual resources, which results in an unbalanced environment. Although, it can be challenging to find the AUT meta in a standard scenario in the earlier stages of test automation. However, the flow may not go as planned.

The good news is – these focused strategies and practical insights can come handy when you integrate testing automation in your project lifecycle.
