Nothing is more crucial than software testing when it comes to creating a strong software QA
strategy. The issue is that software testing covers such a large domain. One can feel overwhelmed
with so many phrases and keywords, forms of testing, and tools.
What is UI testing?
UI testing is described as “the process of ensuring that an application’s user interface not only works
as expected but also enables users to get the most out of it.” Among other things, you can use UI
testing to:
·       Verify that user input is processed appropriately, including whether or not there is any validation
against incorrect input
·       Check sure the app’s user interface isn’t startling or confusing;
·       Ensure that there are no spelling errors, capitalization discrepancies, or even debugging warnings that
have found their way into production;
·       Check for readability and legibility issues, such as font size and color.
UI tests are beneficial because, with them, you can test your whole application. It is inexpensive, and
your employees are freed from monotonous and error-prone tasks, and they are free to do more
creative and perhaps more productive work, eliminating the opportunity labor that manual testing
requires. UI test automation has a lower error margin than manual testing and provides a level of
consistency and repeatability that would be unheard of in manual testing. The collection of UI
automated tests may efficiently serve as a regression testing suite, informing the team when errors
resurface. Because the user interface is the layer of the program with which the user interacts
directly, UI test automation is an important tool for providing a positive user experience.
Some best practices to follow for enhancing the speed and stability of automated UI tests:
UI automation is quickly becoming a standard practice. It’s no longer a mysterious
instrument that no one understands how to use. People, on the other hand, still struggle to
make optimal use of it.  There are a few basic difficulties that you may address and resolve
to make UI automation more efficient and maintenance-free. Follow the below mentioned
best practices to improve the efficiency of the automated UI tests:

  1. Make use of the APIs 
    APIs are the skeleton structure for most apps/web in the present day. You can use APIs to
    manage data generation, data cleanup, and test prerequisites. This would result in improved
    test data management and fewer test data upkeep. In addition to this, you can create a test
    suite using API units for creating test data and avoid including them in functional tests
    unless it is a need for your tests. You can also separate CRUD, and comprehensive functional
    test suites should be maintained. (Be sure to address the requirements’ UI automation
    validation.)
     
  2. Use test design principles and patterns
    In software design, a design pattern is a reusable solution to a common problem. 
    Irrespective of the programming language or paradigm, we could say that each pattern is a
    specific example of a specific solution for a specific issue. We have design principles to go
    along with design patterns. Design principles are guidelines or standards that must be
    followed while creating well-built and reliable software. While patterns are useful for
    particular problems, design principles are useful in any situation.
  3. Never run all the tests across all the target browsers
    The basic notion behind this rule is that performing all tests on all target browsers cabe be
    pointless. You should have a very clear understanding of what you want to accomplish by
    running the tests in various browsers. The primary aim of this operation is to do browser
    compatibility testing, ensuring that the application runs properly on all supported browsers.
    But, to be sure, should you perform all tests in all browsers? Obviously not. A restricted test
    suite may be used to do browser compatibility testing, which includes tests that interact
    with all web components and go through all of the core processes at least once.
  4. Separate tests from automation framework
    You must consider the structure of your framework if you want it to be maintained.
    Structure means the way you arrange your code. The essential ideas are straightforward:
    you should explicitly isolate your tests from the functionality of your test automation
    framework. In other words, each test site should be represented by a class in the tests
    section, and each function of such a class should be a test.
  5. Wisely name your tests
    The titles of the tests should provide a self-descriptive concept of which specific feature is
    being evaluated and therefore, they must be clear. This should be done so that even a year
    after writing the test, you must instantly comprehend what each test validates.
    Furthermore, you should constantly assist your teammates and make all of your testing
    clear to them. Furthermore, if any of the tests fail during the execution of the tests, you
    should be able to figure out which feature was damaged just by looking at the test name. It
    is not worth your effort to double-check what the test truly accomplishes.
  6. For failure investigation keep a record like screenshots
    When researching the causes of a test failure, taking a screenshot is a recommended
    practice and will save you a lot of time. You may create a mechanism that will take a
    snapshot of the browser whenever a test fails. If you don’t have this method yet, or if you’re
    just getting started with your UI test automation, keep this vital advice in mind. The
    implementation of screenshot generation for failed stages may differ depending on the tool
    you use or don’t use. You can use platforms  which have a built-in method for creating
    screenshots.  Furthermore, you can opt for a test automation framework that enables you
    to save screenshots of all test stages for free, so you don’t have to worry about its
    implementation.
  7. Use a BDD framework
    BDD is a software development process that entails implementing software according to its
    behavior. It can be used for a variety of testing scenarios, including component testing, unit
    tests, integration testing, and many more. User Interface testing is one of the most common
    areas where BDD may be used successfully. For a variety of reasons, BDD is suggested for UI
    Automation.To begin with, BDD is a technique that aids in team understanding and
    cooperation both outside and within the team. By using BDD to write your tests, you can
    also develop specs that will assist your team better understand the tests and requirements.
    This implies that, in addition to developing your tests, you’re also documenting them. This
    guarantees that you do not waste the time of other team members as well as your own,
    since you do not need to explain or assist with such tests if they are confusing. Second, BDD
    will help you to get an understanding of these tests by the business side (e.g., testers and
    project managers). This adds to the value of testing since they can offer suggestions based
    on the advantages to the company. Lastly, BDD normally requires you to adhere to a rigid
    code organization structure, which helps you avoid duplicating code. This is accomplished by
    using different components known as steps or actions as the test’s building elements.
  8. Test automation frameworks should be portable 
    First and foremost, do not save test automation files locally! Test automation files should be
    added to the framework if they are necessary for test execution. If they’re small, you may
    save them with the framework in the control version. If they’re large, you may save them to
    any cloud storage service. Then, if the files aren’t already there, develop a method that
    uploads them to the correct places during the initial test runs.
  9. Do not use Thread.sleep()
    Irrespective of the complexity of your online application, this is one of the most important
    rules that you must follow. Your test thread is blocked for an exact amount of seconds by
    sleep or precise timeout (better known as Thread.sleep() method and analogs). In other
    words, it allows you to suspend your testing.  Many variables influence the behavior of
    online applications, including  system capabilities, network speed, and the present load on
    the application servers. Because of all of these variables, it’s impossible to anticipate how
    long a page or web element will take to load. As a result, adding a timeout and pausing
    script check execution for at least a specific length of time is occasionally necessary.
    UI test automation is stable and your developers and testers are the ones who are solely
    responsible for the stability of your UI test automation framework. True, robust, and
    dependable UI automation is time-consuming, but it’s also a pleasant experience. You have
    to make a decision at the start of your framework development: will you employ a tool to
    assist you achieve your objective and solve your problems, or will you construct software
    that you will have to deal with on a regular basis? You can use platforms like LambdaTest
    that can perform automated tests on a secure, reliable and scalable automation cloud and
    run these tests on 3000+ browsers and devices. You should end up with a solid and robust
    UI automation if you follow these above-mentioned best practices. Although not all of the
    recommendations will apply to your project, they should provide you additional possibilities
    for your future implementation.
