9 Automated Testing Certification Mistakes to Prevent Tutorial

If you work in software development, you are aware that creating products that are competitive calls for consistent testing.

But how can you avoid frequent pitfalls in automation testing?

Without testing, it's likely that your software won't perform as it should and that you'll have trouble finding users who will pay for it.

Finding flaws or problems purely through manual testing might take a lot of time and effort. Additionally, it is a time-consuming and costly process.

You may create higher-quality software in less time and at less expense by automating the tedious testing processes.

Additionally, Automation Testing Course enables you to test more code more quickly and accurately. The execution of manual tests that cannot be automated frees up QA resources due to automation. Automated unit tests can also serve as a safety net for developers who need to refactor code rapidly and confidently before releasing it to production.

But be careful—many inexperienced testers and developers fall victim to the same frequent mistakes in automation testing.

All testing methodologies, including unit testing, integration testing, and end-to-end testing, have these traps.

Avoid slow tests and long execution durations

Your programme will progressively become more sophisticated as it is being developed. However, testing becomes more challenging the more advanced the software is.

Everyone feels the pain of an automation framework with tests that take weeks to write and months to run. Both testers and developers don't want to waste their time writing more tests or waiting around for results interminably.

The lead time for testing will be greatly shortened if you focus on testing simple or repetitive aspects. Additionally, it will free up employees for more exploratory testing or tests that need manual attention.

A breach between developers and testers can be avoided entirely by avoiding sluggish tests.

2. Make sure your tests are understandable and straightforward

Making your code as simple to read as possible is a great idea because most people spend far more time reading source code than they do generating it.

It won't ever read like Hemingway, but it doesn't mean that someone other than you can't understand it.

The Golden Rule of testing, according to Yoni Goldberg, is that one must be able to comprehend the purpose of the test right away.

Your team colleagues will congratulate you and you will feel great about making your tests readable.

You won't wonder, "What was I doing?" when you reread those tests a year from now. or "What even was the purpose of this test?"

It goes without saying that you cannot use a test if you do not comprehend its purpose. What use is a test to you or your team if you can't use it?

A test that you struggle to understand is worthless.

Debugging is likewise a nightmare with unreadable code.

3. Avoid overusing abstraction

Try to keep your testing straightforward. Limit your use of abstraction.

Keep in mind that automated tests are NOT real-world code.

Don't misinterpret this in any manner.

Of course, testing should be treated the same as production code, but there are some patterns and standards that are crucial for production code but inappropriate for test code.

The Don't Repeat Yourself (DRY) philosophy exhorts testers to do everything possible to avoid repetition.

However, if you use the DRY concept too heavily, your tests will be more difficult to read and comprehend.

Therefore, while utilising this approach in automation code may be a good idea in production code, you should reconsider. Instead, perhaps duplicate parts of the description to make the test's goal more obvious. Test readability always takes precedence over the DRY concept.

4. Whenever you can, isolate your tests.

When you run numerous tests but don't alter anything between them, your value is inconsistent.

You're asking for trouble if your current test depends on a previous test that was successful. Any subsequent tests that are conducted are likely to fail or yield inaccurate findings if the previous test failed or the data was corrupted.

Your tests will be more valuable if you isolate them since isolated tests will produce accurate and consistent results.

Ramona claimed that she always resets her application to a fresh installation before testing. She can then guarantee that all tests are insulated from outside influences and use the same data.

The data she requires for the test is created in the second phase by the user through an API call. The order of the tests is irrelevant, and they can all be done individually.

5. Give mission-critical elements testing priority.

Prioritizing which tests are most crucial will help because there are only so many hours in a day and so much testing that can be done during those hours.

Testing various components in a different order will lessen the likelihood that a crucial component will fail.

There are a few considerations you should ask yourself before choosing which aspect to test first:

How probable is it that this user will make a mistake?

Which areas cannot tolerate mistakes?

An region is not high on the list of testing candidates if it is unlikely to have an error and is not mission-critical.

On the other hand, places like user registration or checkout cannot afford any mistakes.

In regions of great importance, thorough testing is essential.

6. Follow a defined testing structure

Your tests will remain neat and consistent if you have a clear testing structure.

Regardless of the programming language you choose, the AAA testing pattern is a simple and effective structure to follow to assure acceptable code quality.

There should be three phases to each test:

1) Arrange - Begin by outlining the prerequisites for your scenario. After that, think about the many variables and ask yourself what is necessary to make sure your test is successful. Next, you should group your jobs into logical sequences.

2) Execute the testing in accordance with the stages you outlined for yourself.

3. Assert - After testing, state the outcome of your findings.

You can keep your automation testing on the right path by implementing the AAA pattern.

7. Avoid basing tests on selectors that might change.

Writing tests based on elements like CSS selectors that can change in the future can lead to failed tests.

This could then result in a perplexing situation where your test failed without a problem and you were left trying to figure out why.

Naturally, your test is out of date; there isn't a bug to be detected.

Focus on selections that are less likely to change, such as data attributes. It's doubtful that your engineers will alter those very soon.

This tip comes with a bonus suggestion: don't test implementation specifics!

You risk getting false positives and false negatives while testing implementation details.

When you restructure the application, the test can fail, giving you a false negative. Alternatively, even if you damage the application code, the test can still pass, giving you a false positive.

8. Avoid using set wait times.

Fixed waiting periods during exams are a bad concept for a number of reasons.

A test can fail if it runs faster than the website needs to respond. If you wait too long, your test will be slow and wasteful. If you wait too little, your test may fail if your app takes too long to load.

Instead, attempt to wait for UI changes like your users would. It can entail holding off until a loading spinner disappears, an animation is finished, or all of the text has loaded completely.

9. Avoid using placeholder names like "foobars"

Consider a coworker of yours reviewing a test you authored six months ago. Think about what must be going through her mind when she reads "foobar" from her perspective.

What does the exam do, she might inquire? What does foobar mean in this context? Is it a thing? A client's name? Something important or totally unimportant?

Using placeholder names like foobar can make it more difficult for people to comprehend your test.

Use names or placeholders linked to actual products instead. Anyone who reads your test will then understand what it is for.

Conclusion

An Automation Test is faster and more clear-cut, without extensive human errors. However, Test Automation is not necessarily a substitute for Manual Testing. Each of the approaches has its own set of pros and cons. If the software being developed, happens to be too large and complex; Automation Testing Training is often the first choice; while there are certain kinds of test cases wherein conducting an Automation Test would be futile. Business Testers, Software Development Engineer in Test (SDET) and Software Developers, happen to be the prime users of Test Automation.
