In the past several years, we have heard most engineers from various projects complaining about tests’ stability and reliability. But are they so unstable and unreliable? UI automation testing is indeed very hard, and creatures that could be full of different wholesalers. Nevertheless, our hands make automation instead of an old unstable country road.
Top UI Automation Practices
This article will aggregate and define the top 15 best practices for creating a solid and maintainable UI automation testing framework. You will also discover some handy examples of these principles.
Do not rely only on UI automation testing
One of the main best practices we should consider is not relying on UI automation on loan to stop. It really should be confident that our whole UI automation suite will always catch up to 90% of existing bugs on our release. It would help if we still remember that the high-level test will surely be the third different shield for catching all the remaining issues that were not seen on the first two levels.
Consider using a BDD framework
BDD is a procedure that helps teams understand each other. Creating strong outside and inside through collaboration. Writing about tests with BDD will also help us develop specifications that can help our team understand the difficulties and requirements much better. It also means that along with our tests, we are creating better test documentation, and it will ensure that with don’t waste other team members’ time and our own time because they are not required to explain and help with such test if they are unclear.
Always use test design patterns and principles
A design pattern is a reusable solution for a simple problem in software design. We can say that each print is a particular example of a specific solution for a particular problem regardless of the programming language or the criterion. We have design principles in implementing design patterns. These principles provide us with the guidelines and rules required for constructing well built and maintainable software. While these practices apply to specific issues, design principles apply regardless of context.
Never use Thread.sleep() unless there are specific test requirements
Thread sleep of web application depends upon network speed, machine capabilities on the current loan application servers. We cannot always predict how much time it will take to load the specific page or web element due to all these factors. That is the reason sometimes we might want to add a timeout and pause script execution for at least a certain amount of time.
Two not run all tests across all target browsers
This rule’s main idea is that running all tests against all target browsers is redundant and unnecessary. To clearly understand what we will achieve by having our difficulty across different browsers, the main goal is to perform browser compatibility to verify that the application works correctly on all supported browsers.
Separate our tests from our test automation framework
For making our framework maintainable about its structure. By structure in the way, we organize our code. The basic principles are very simple. We should separate our tests from our test automation framework functionality for the finish in different words; each class in the test section should represent a test site. At the same time, each function of such courses should be a test.
Make our UI testing framework portable
You should not store test automation files on our local machine. If we have test automation files required for the execution of the test should be attached to the framework will stop if they are relatively small we can store them under the control version along with the frame of itself and stop if they are big then we can use external storage like Amazon S3 or any other cloud storage.
Name tests wisely
The best name should be very clear and provide a self-descriptive idea about what exact functionality is being tested by using this test. Firstly we are required to understand what each test verified, even the year test. We should always help our team members and make all our tests clear for them.
Use of assertions If required to make a list of related sites on the same web page
Assertions are designed to make the test fail if a statement failed. Originally affirmations work created for the unit test. It is a very good practice since each unit test would make only one specific assertion.
Take a screenshot for failure investigation
This practice will help us save a lot of time while investigating the reasons for a test failure. We can implement a mechanism that will make a browser screenshot in case a test failed.
Need test simpler instead of adding comments
The test should always be very clear and simple to read. If we feel we are required to leave a comment to understand what is done in this line, then we must take a step back and think again about what we are doing wrong.
Follow the green tests run policy
The application already has a list of bugs prioritize slower, and the team is not working to fix these issues in the upcoming future. In this case, most UI testing engineers ignore these tests as they lead them inside the runner-up finish off with many red tests at the end of the test execution.
The utilization of data-driven tests instead of repeated tests
Data-driven tests are remarkably useful when we need to test the same workflow by using different types of data.
All tests should be independent
Dependencies are going to make our tests hard for reading and maintaining. We will get into some trouble during parallel automation because we cannot guarantee our tests’ order during similar testing.
Setup detail automation test reporting
UI automation reporting is remarkably important for optimizing our work as a QA automation engineer. You should not spend more than 10 to 20% of our time the refined test results from different test executions.
