In today’s era, the software testing trend is changing, as we can see the dominance of automation testing in the software development process. Most organizations are choosing cloud-based automation testing processes to make their software testing efficient and time-saving with more accuracy and improved software quality. You must write some effective automated test scripts to perform automation testing more accurately and efficiently. 

Test scripts are line-by-line descriptions that contain information about system functions that must be performed to verify an application or system under test. The test document should outline each step with the expected results. This automated script enables the tester to scan each level of various devices systematically. The test script should contain the entries to be included and the expected results. In this article, you will see how you can write effective automated test scripts for the automated testing process.

What are Automation Testing and Automation Test Scripts?

Automation testing is a software testing concept software developers and the QA team widely use. This testing is done to improve various factors of the software application. These factors are software features, functionalities, reliability, etc. You can perform automation testing using either physical devices or tools. Some cloud-based tools and technologies are more efficient for automation testing. 

For instance, manual regression tests, which verify that nothing breaks whenever a developer submits a pull request, can require considerable teams to put in dozens of hours of laborious effort. Instead, you may automate this effort by linking your product with your preferred testing suite using an API. Automated testing focuses on executing the test cases quickly to make the software seamless and user-friendly. Now, coming to the automation test scripts. Automation test scripts are defined as the testing scripts that are written using automated tools to perform software testing by the developer and QA teams. The automated test scripts programmatically perform the setup and validation independently.

Best Practices for Writing Effective Automated Test Scripts

Now, let us see some of the best practices the QA team should follow to write effective test scripts for automation testing.

Establishing a Test Automation Architecture

In today’s time, when there is much competition in software organizations, you can see the importance of automation testing in the software development process. But before implementing the test automation, it is very important to understand the test automation architecture. What methods will you use for writing tests for the automation testing process, etc? 

Apart from these, establishing the automation testing architecture for writing effective tests helps to make a clear roadmap to complete the testing and make your software application ready to use in the given time. Finishing your work in the provided time also helps to make your impression among your stakeholders. Establishing a baseline is one of the most critical aspects of writing practical tests for test automation. A baseline is a set of minimum criteria your tests must meet to succeed. These various criteria are code coverage, performance, functional accuracy, etc.

Without a baseline, the software testers and developers find it difficult to choose the tasks of each test case. And if the test cases are not performing according to expectations, the testing time increases, and it’s a waste of time. All these are the reasons you should always establish a test automation architecture for writing tests for automation testing.

Identify the Test Matrix

Making a test matrix is making a list of various web browsers, types of devices, operating systems, and their versions for which you will perform automation testing. Because not all your applications may be compatible with all web browsers and device configurations. There are many reasons behind it, and one of them is that it has many functions and CSS properties. But we make our software application, website, and web application more compatible by writing practical tests for automation testing. 

Performing the test automation by planning the test matrix helps write practical tests, ultimately making your software application productive and effective. So, to write practical tests for automation testing, we need to build a matrix list to decide which software application is essential for that particular device, configurations, etc. 

Create Tests that are Resistant to UI Changes

When writing tests for automation testing, it is essential to create practical tests resistant to user interface (UI). It means creating the tests for automation testing that can be used to test the software application efficiency, performance, and user interaction basis. This is very essential, especially in the initial stage of software development. Because in the early stage of software development, the software’s user interface is liable to change frequently.

One of the best ways to write effective tests for automation testing that are resistant to UI is to use the concept of reverse engineering. This concept is basically about how the objects. In general terms, it recognizes the objects based on the UI factors such as location and coordinates. 

In this case, the success rate of test cases gets reduced. But this can be avoided by some practices. You can provide the controls and nomenclature for the objects. It becomes much easier for automated software testing to run tests successfully without changing names every time. This is a very effective way to write tests resistant to UI and helps create practical tests for automation testing.

Choosing Appropriate Test Automation Tools

A test automation tool is a software management tool software developers use to write practical tests and execute automation testing. So many tools are available to perform automation testing on the cloud. Also, these tools help the developers to manage and report automated tests. The test management tools can also be integrated with various other software tools like VCS (Version Control System), defect tracking, and CI/CD systems. Using these additional tools helps to keep up with the latest trends and write effective tests for your automation testing.

Using the appropriate tools for writing tests also helps to speed up the test automation process. These software management tools offer various features, such as a customizable dashboard, multiple types of widgets, real-time metrics, interactive reports, graphical representation, etc.  

Some key points should be considered while choosing the right test automation tools to write tests. These points are like the application’s technological stack, the team’s experience, and your budget. Selenium, Appium, and LambdaTest are a few well-liked automation testing tools. Selecting the appropriate automation tools demands careful thought. Let us see these points briefly one by one.

  • Technological Stack: The technological stack of your application significantly impacts the tools you choose. While some automation systems are better suited for desktop software or mobile apps, others specialize in web applications. There can be no compromise on compatibility with your tech stack.
  • Team Expertise: Consider the knowledge and experience of your testing team. It might go more smoothly if they are familiar with a particular automation tool. On the other hand, consider the learning curve if they must start from scratch.
  • Budget: Many automation technologies range from open-source solutions like Selenium to for-profit solutions like LambdaTest. Naturally, your pick will be influenced by your budget. Remember that purchasing a dependable tool can frequently result in long-term cost savings.

LambdaTest is an AI-powered test orchestration and execution platform that lets you run manual and automated tests at scale with over 3000+ real devices, browsers, and OS combinations.

Identify Slow and Failing Tests

As a software developer and testing professional, the worst nightmare is when your tests get slow or sometimes fail. As we know, automation testing is an essential part of the whole software development process. Because it improves our software application and increases end-user user experience. There is a need to write effective tests to perform efficient automation testing.  

However, not all tests are created equal. Some tests may be faster, others are slower, and some are more likely to find bugs. When the testing team performs automation testing for errors and bugs, the team needs to identify slow or failing tests to consider both the speed of the test and the likelihood of the test finding errors.

A slower test, which takes much time to find errors or bugs, is not worth it compared to tests that find bugs easily and quickly. So, the team should consider both factors while writing the tests for automation testing to write effective tests.

Using Data-Driven Tests

Data-driven tests can be used to write effective automated test scripts. These automated tests use data that is read from a file and included in the test. There are various sources from which you can read the data. These sources are databases, Excel files, CSV files, JSON files, etc. Data-driven tests have various benefits when it comes to automating testing, such as:

  • Simpler maintenance: You can set the input and output values in a data file to execute the same scenario with different values. Every test coverage will be automatically iterated through the test.
  • Easier understanding: When you use data-driven tests for automation testing, all input and output values are displayed in a single location. So, it is easier for non-technical people to understand what scenarios your automated tests test.

Conclusion

To perform an automation testing process, it is a must to write effective test scripts. This helps to make your testing process productive. The testing team and developers should follow various practices that you have seen in this article. Hope you got an idea of how to write effective automated test scripts for automation testing.
