The Importance of Test Automation in Software Projects

Test Automation Importance
What is Automation Testing?

Automation testing is testing a software application using another application/ Library/ Program to ensure it meets strict requirements. It tests for bugs, defects, and other issues that may arise with product development.

It involves an automation library/tool to execute a test suite and predefined actions on an Application Under Test. The testing library/tool compares actual outcomes with the expected result to generate detailed test reports. Test automation speeds up the overall testing process. It helps in the quick delivery along with the high-quality product. Test automation helps to increase the overall software development process efficiency and ensures robust software quality.

Types of Automation Testing:

Functional Test Automation

◦      UI Automation

  • Web App
  • Mobile App
  • Desktop App

◦      Security Test Automation

Automation Tools/Libraries:

1. UI Automation
 Tools/Libraries:

Selenium, Appium, EggPlant, UFT, Katalon Studio, Test Complete, Calabash. 

2. API Automation Tools/Libraries:

Jmeter, Postman, Postwomen, Soap UI, Fiddler, Rest-Assured, Uni-rest, HttpClient Library

3. Performance Test Automation Tools:

Benefits of Automation Testing:

The following are the benefits of Test Automation that make it an important aspect of Software Development.

1. Extensive Smoke Testing

It is recommended to perform regular and repetitive smoke testing to avoid breakdown or downtime. But performing regular and repetitive smoke testing through a manual process is expensive and time-consuming. To tackle this problem, we have to go for automated smoke testing. This includes the creation of automated test suites based on our smoke test scenarios; the same can be executed as per demand or requirement.

For example, in the current project, we have regular product releases with many builds generated by the dev team, making it tough to do the smoke testing for those builds. So we created an automated smoke suite and a Jenkin Job to trigger it.

2. Seamless Regression Testing

Automation testing plays an important role in regression testing because it is not feasible to test all the tests whenever a bug fix or a new feature gets implemented using manual testing.

So, in our project, we have created a regression (API/UI) test suite, which we trigger on a daily/Demand/Git branch merge basis using CI/CD pipeline.

3. Improved Accuracy

Human Beings are meant to make mistakes, so whenever we perform manual testing, we might miss bugs, document incorrect steps to reproduce the bug or miss a step, etc.

But automation testing has 100% accuracy as the steps to test the functionality/ features are always the same and repeatedly executed.

4. Thoroughness in testing

Automation testing is more like one-time creation and multiple time consumption/execution. It will help the automation tester focus/work more on scripting additional test cases, which eventually covers all the possible test paths for a test scenario.

So through automation, we cover all the possible ways/paths to test specific functionality.

5. Ease of reproduction bug

In manual testing, if the manual tester finds a bug in the application, he must recall every step required to reproduce the bug. So many times, it is tough to recall all the steps and reproduce the bug.

But with the help of reporting libraries like the Extent report, we get detailed information on test failure with detailed logs and steps that help reproduce the bugs for every test suite execution.

6. Anytime Test Execution (24/7)

We can execute these automation test suites on-demand at any time, anywhere, and at regular intervals, including weekends/holidays.

So, we can achieve this by creating jobs using CI/CD tools like Jenkins, TeamCity, and Azure to execute these jobs on demand.

7. Reusability

In automation testing, we must do “One-time scripting and multiple/repetitive/regular execution.”

The same set of test scripts is used for every release as a part of either smoke/sanity or regression testing.

Once we are ready with our test script, we just need to push it to the version control system, and then we can pull those scripts as per demand on the required platform and then execute those.

8. Detailed Reporting and Logging

Whenever we test any application, we have to provide detailed information about the types of tests, number of tests, number of pass/fail/skipped tests, and platform(OS, Browser, build version) information as well as all stakeholders.

So with the help of reporting libraries like ReportNg, Extent Report, and Allure Report, which can be easily integrated with the automation libraries and provide detailed interactive information with graphs and pie charts.

9. Cross-Browser and Cross-Platform Testing Support

To support a wide range and variety of end-users for a software system, we have to make sure that the system works seamlessly on all the browsers and platforms with combinations of different versions.

Automation testing uses tools/libraries that execute the same test scripts against multiple browsers and platforms. We have used a selenium grid for cross-browser and cross-platform testing.

10. Data-Driven Testing

Several times we have to test a few features/functionalities using multiple test data sets to verify their absolute working. We can test such features in automation without creating separate scripts for every data set. We can test the same feature/ functionality with a different test data set, such as Login functionality with Valid credentials and Invalid credentials.

We have used the @DataProvider annotation of the TestNg library to achieve data-driven tests in our projects.

11. Distributed Test Execution

Automation testing libraries/tools have the capabilities to execute our test suites in a distributed manner. To speed up test script execution against the application under test, we can spread the set of test scripts to be executed on multiple machines/ nodes.

In one of our projects, we used Selenium Grid to perform Distributed test execution.

12. Parallel Testing On Multiple Platforms

In today’s world, people are using software applications from different devices, operating systems, browsers, and different versions of all of that as well, so to build an application that will be robust and comply with all the platforms smoothly, we have to do regressive testing.

Automation testing helps to handle this overhead and complex scenario with ease. With minor changes in the prerequisites of the automation test script, we can easily execute an available set of test scripts on multiple platforms with less time by executing parallelly.

13. Time Efficient

An application’s time delivery is a crucial factor for the success of the application and enterprise as well as high quality. So to achieve this, we have to fasten our testing process, which is tough through manual testing as a tester has to work extra hours and on weekends.

We can fasten the testing process through automation by executing the test suites repeatedly, on-demand, and on multiple/different platforms without investing testing time.

14. Reduced Business Costs & Better Utilization Of Manpower

Enterprise majorly invests workforce in automation testing at the initial phase; later, it is more of maintenance. Once the testing team is done with automation of all the required sets of test cases, then we will be left with only monitoring and reporting efforts.

So it is a one-time investment and regular outcome process, resulting in better workforce utilization with high-quality output.

15. Maximize The Test Coverage

By automating end-to-end test scenarios, we cover almost all the aspects of a software system from installation/deployment, interacting with GUI, interaction with different software system modules, and Database.

So, all this results in maximizing the overall test coverage of the software system.

16. Maximizing Return On Investment

Automation testing helps an enterprise deliver its software quickly into the market with regular and extensive test suite execution across multiple platforms, making the software bug-free and robust with the help of fewer resources compared to manual testing.

Summary:

In essence, it can be stated that automated testing results in cost reduction, time and effort saving, quicker feedback, consistency, and quicker results, thereby directly contributing to increasing productivity and leading to maximization of profits.

These benefits of automation testing contribute to the faster and more reliable delivery of Software Solutions, which leads to the success of an enterprise.
