Automation Testing & Its Implementation – Is it Worth it?

All this buzz about “Automation” makes sense as we realize how rapidly we are moving into an era of technological developments. It mainly focuses on enhancing efficiency by minimizing human intervention to uproot any human errors. The manual processes are more prone to errors as compared to the automated processes. Moreover, automation is an excellent way to conserve our most valuable resource – and that is time.

Does the idea of automation sound intimidating to you too? Undoubtedly, it does in the beginning. We mostly consider automatic processes beyond our control. But in fact, if we do them with proper planning and management, and set specific checkpoints, we can control them efficiently.

Talking about automation, let’s talk about Automation Testing.

What is Automation Testing?

Automation Testing is a software testing technique that compares the resulted outcomes with the expected ones. In this process, we use automation tools for certain repetitive tasks that are difficult to perform manually and require a lot of time.

Automated Testing is essential for several important reasons, such as:

  • It is less susceptible to errors
  • It speeds up the execution of tests
  • You can leave automation testing unattended; it does not require human intervention
  • Automation testing is favourable for multilingual sites and software
  • It is less money and time consuming

Automation Testing is performed on specific Test Cases. Wondering what Test Cases are?

A Test Case is a suite of conditions against which a tester determines the system’s correct working and requirement. It is recommended that you test them manually at least once before putting them under the automated testing. The following types of test cases should be preferentially automated:

  • Time Consuming Test Cases
  • Test Cases that are difficult for manual testing
  • Highly repetitive Test Cases

Test Automation Frameworks

A framework developed by various hardware, software, and automation testing tools ensures reliable analysis of any issues or bugs in the system or application under testing (AUT). It is actually an execution site for automated testing and enhances the efficiency of automated test scripts. Moreover, it provides a method to maintain the uniform design across different test scripts so that all testing does not depend on individual test-cases. Test Automation Frameworks ensure timely bugs detection, uprooting its cause, and reducing testing dependency on the teams. It improves the utilization of various resources and ensures that the testing process goes uninterrupted with no to minimum human resources. There are different types of Test Automation Frameworks such as:

  • Linear Scripting Framework
  • Modular Testing Framework
  • Data-Driven Testing Framework
  • Keyword Driven Testing Framework
  • Hybrid Testing Framework
  • Keyword Driven Testing Framework
  • Hybrid Testing Framework
  • Test-Driven Development Framework
  • Behavior Driven Development Framework

Linear Scripting Framework

In this framework, the test scripts are executed individually and incrementally, adding new interaction every time. It is based on the concept of the record and playback model.

Modular Testing Framework

Being built on the concept of abstraction, it has a layer that hides the components from the application under test. This Framework makes sure that the changes made in any part of the application do not affect the core components.

Data-Driven Testing Framework

In this framework, a single script executes all the test cases and stores both the input and output results in a separate file.

Keyword Driven Testing Framework

This framework is an application-independent framework. It uses keywords to predict the action that you are performing on the application under test. Functionally, it is an extension of data-driven testing framework

Hybrid Testing Framework

Hybrid Testing Framework is a combination of different testing approaches, such as modular, data-driven, and keyword-driven testing.

Test-Driven Development Framework

It is also known as TDD and is well known for increasing the speed of tests and fulfilling the testing requirements. It uses automated unit tests to find one or more issues or bugs.

Behavior Driven Development Framework

Behavior Driven Development Framework focuses on system behaviour. In BDD, the testers make test cases in the English language, which helps the non-tech persons analyze and understand the outcomes easily.

Although Automated Testing has not entirely ruled out Manual testing, it is still better than the manual one in saving time and manpower. Implementing automation testing from scratch is a decision that requires proper homework. You can not imply Automation just because you are fascinated by the word! If, however, you work in the following key areas, you should better consider automation:

Regression Testing

Automated Regression Testing is more feasible because it must be executed after every release to ensure proper functioning.

Complex Functionalities

Problematic functional areas that involve calculations would be better with automated systems to avoid any human errors.

Smoke Testing

Automated testing saves time by analysing the build’s quality – whether it needs thorough testing or not.

Data-driven Testing

Data-driven Testing involves multiple data sets, so automation will help rule out any possibility of mishappenings.

Cross-browser Testing

One of the most significant issues in a software or application is its support of different browsers or versions. It is also referred to as Responsive testing. For cross-browser testing, we need to execute a series of repetitive tests for different browsers, which takes a lot of time and effort. Hence, automating the process will help to make the testing quicker and efficient.

Repetitive Tests

Repetitive tests remain the same from one cycle to the other. Therefore, repeating them over and over again is tiresome and boring. Hence, automating the repetitive test would be in your favor.

Performance Testing

You can do the performance testing manually. It requires a tool to test the performance of a software or application efficiently. Hence, there is no manual alternative to automated performance testing.

Automated Testing Process

Before starting off with the process, you should be able to evaluate the need for automation. Anything impromptu would not lead to an efficient automation processing; therefore, it is quite advisable that you define your goals and priorities, plan automated testing strategy and select the right automation testing tool based on your project requirements. Once you have done it, you should be able to decide what cases you want to automate, develop test data, and execute the tests. The process of Automated Testing goes in the following steps:

  1. Selection of the Test tool depending on the application under testing.
  2. Defining the areas that need automation
  3. Planning, designing and developing the tools, framework, schedule, and features, etc
  4. Execution of the test by automation scripts and get the detailed reports
  5. Maintenance of the Automation testing by reviewing the scripts and improving them as and when required.

Following are the benefits of Automation Testing:

  • Covers a wide range of application features
  • Gives reliable and consist results
  • Saves both time and cost
  • It is highly accurate
  • Human intervention is minimum
  • Increase the efficiency of testing
  • The test scripts can be used again and again
  • Frequent and thorough testing is feasible
