Automation Testing

In the earlier article on software testing, we learned that software testing is classified into two types of testing, which are Manual testing and Automation testing. Both manual and automation testing have their characteristics and approaches that make both the testing technique different from each other.

Here, we are going to learn about the following related topics of automation testing:

  • Introduction to Automation testing
  • Why do we need to perform automation testing?
  • Different approaches used in automation testing
  • Automation testing process
  • What are different challenges faced during the automation testing process?
  • Automation testing tools
  • Benefits and Drawbacks of automation testing.

Introduction to Automation Testing

Another software testing method is automation testing, which is used some specific tools to execute the test scripts without any human interference. It is the most acceptable way to enhance the efficiency, productivity, and test coverage of Software testing.

With the help of an automation testing tool, we can easily approach the test data, handle the test implementation, and compares the actual output against the expected outcome.

Automation Testing

In automation testing, the test automation engineer will write the test script or use the automation testing tools to execute the application. On the other hand, in manual testing, the test engineer will write the test cases and implement the software on the basis of written test cases.

In test automation, the test engineer can execute repetitive tasks and other related tasks. In manual testing, it is a tedious process to implement the repetitive take again and again.

In other words, we can say that the main concentration of test Automation is to change the manual human activity with systems or devices.

The automation testing process is a time-saving process as it spends less time in exploratory testing and more time in keeping the test scripts whereas enhancing the complete test coverage.

Note: We perform exploratory testing whenever the requirement does not exist.

Why do we need to perform automation testing?

  • In software testing, automation testing is required to test the application because it offers us a better application with less effort and time.
  • Some organizations still perform only manual testing to test the application as those companies are not fully aware of the automation testing process.
  • But now, they are aware of automated testing and executing the test automation procedure in their application development process.
  • To implement the automation testing, we required pretty a considerable investment of resources and money.

The execution of automation testing provides us various advantages, which are as discussed below:

  • Reusability
  • Consistency
  • Running tests anytime (24/7)
  • Early Bug detection
  • Less Human Resources

Automation Testing

1. Reusability

We can re-use the test scripts in automation testing, and we don’t need to write the new test scripts again and again. And, we can also re-create the steps which are detailed as the earlier ones.

2. Consistency

As compared to manual testing, automation testing is more consistent and way faster than executing the regular monotonous tests that cannot be missed but may cause faults when tested manually.

3. Running Tests 24/7

In automation testing, we can start the testing process from anywhere in the world and anytime we want to. And even we can do that remotely if we don’t have many approaches or the option to purchase them.

4. Early Bug Detection

We can easily detect the critical bugs in the software development process’s initial phases by executing automation testing. It also helps us spend fewer working hours to fix these problems and reduce costs

5. Less Human Resources

To implement the automation test script, we need a test automation engineer who can write the test scripts to automate our tests, rather than having several people who are repeatedly performing the tedious manual tests.

Automation Testing Methodologies

Automation testing contains the following three different methodologies and approaches, which will help the test engineer to enhance the software product’s quality.

  • GUI Testing
  • Code-Driven
  • Test Automation Framework

Automation Testing

Now, let’s understand the different approaches of automation testing one by one:

1. GUI (Graphical user interface) Testing

In this approach, we can implement that software or an application, which contains GUIs. So, that the automation test engineers can record user actions and evaluate them many times.

We know that the Test cases can be written in several programming languages like JAVA, C#, Python, Perl, etc.

2. Code-Driven

The code-driven technique is the subsequent methodology used in automation testing. In this method, the test engineer will mainly concentrate on test case execution in order to identify whether the several parts of code are performing according to the given requirement or not.

Hence, it is very a commonly used method in agile software development.

3. Test Automation Framework

Another approach in automation testing is test automation framework. The test automation framework is a set of rules used to generate valuable results of the automated testing activity.

Similarly, it brings together test data sources, function libraries, object details, and other reusable modules.

Automation Testing Process

The automation testing process is a systematic approach to organize and execute testing activities in a manner that provides maximum test coverage with limited resources. The structure of the test involves a multi-step process that supports the required, detailed and inter-related activities to perform the task.

Automation Testing

The automation testing process completed in the following steps:

Step1: Decision to Automation Testing

It is the first phase of Automation Test Life-cycle Methodology (ATLM). At this phase, the main focus of the testing team is to manage expectations from the test and find out the potential benefits if applying the automated testing correctly.

On adopting an automated testing suit, organizations have to face many issues, some are listed below:

  • Testing tool experts are required for automation testing, so the first issue, to appoint a testing equipment specialist.
  • The second issue is, choose the exact tool for the testing of a particular function.
  • The issue of design and development standards in the implementation of an automated testing process.
  • Analysis of various automated testing tools to choose the best tool for automation testing.
  • The issue of money and time occurs as the consumption of money and time is high in the beginning of the testing.

Step2: Test Tool Selection

Test Tool Selection represents the second phase of the Automation Test Life-cycle Methodology (ATLM). This phase guides the tester in the evaluation and selection of the testing tool.

Since the testing tool supports almost all testing requirements, the tester still needs to review the system engineering environment and other organizational needs and then make a list of evaluation parameters of the tools. Test engineers evaluate the equipment based on the provided sample criteria.

Step3: Scope Introduction

This phase represents the third phase of Automation Test Life-cycle Methodology (ATLM). The scope of automation includes the testing area of the application. The determination of scope is based on the following points:

  • Common functionalities of the software application that are held by every software application.
  • Automation test sets the reusable range of business components.
  • Automation Testing decides the extent of reusability of the business components.
  • An application should have business-specific features and must be technically feasible.
  • Automation testing provides the repetition of test cases in the case of cross-browser testing.

This phase ensures the overall testing strategy that should be well managed and modified if required. In order to ensure the availability of skills, testing skills of a particular member and whole team are analyzed against the required specific skills for a particular software application.

Step4: Test Planning and Development

Test planning and development is the fourth and most important phase of Automation Test Life -cycle Methodology (ATLM) because all the testing strategies are defined here. Planning of long -lead test activities, the creation of standards and guidelines, an arrangement of the required combination of hardware, software and network to create a test environment, defect tracking procedure, guidelines to control test configuration and environment all are identified in this phase. Tester determines estimated effort and cost for the entire project. Test strategy and effort estimation documents are the deliverables provided by this phase. Test case execution can be started after the successful completion of test planning.

Step5: Test Case Execution

Test case Execution is the sixth phase of Automation Test Life -cycle Methodology (ATLM). It takes place after the successful completion of test planning. At this stage, the testing team defines test design and development. Now, test cases can be executed under product testing. In this phase, the testing team starts case development and execution activity by using automated tools. The prepared test cases are reviewed by peer members of the testing team or quality assurance leaders.

During the execution of test procedures, the testing team directed to comply with the execution schedule. Execution phase implements the strategies such as integration, acceptance and unit testing that have defined in the test plan previously.

Step6: Review and Assessment

Review and assessment is the sixth and final stage of the automated testing life cycle but the activities of this phase are conducted throughout the whole life cycle to maintain continuous quality improvement. The improvement process is done via the evaluation of matrices, review and assessment of the activities.

During the review, the examiner concentrates whether the particular metric satisfies the acceptance criteria or not, if yes, then it is ready to use in software production. It is comprehensive as test cases cover each feature of the application.

The test team performs its own survey to inquire about the potential value of the process; if the potential benefit is less than sufficient, the testing team can change the testing tool. The team also provides a sample survey form to ask for feedback from the end user about the attributes and management of the software product.

What are different challenges faced during the Automation testing process, and how to overcome them?

The automation testing process carries about large numbers of advantages for an organization. Usually, with automated testing, the testing team of the specified method of software validation can accomplish the amplified test coverage.

Though we may face various challenges during the automation testing process; therefore, we need a thorough follow-up process to reach successful test automation execution.

Some of the common challenges are as discuss below, which we might encounter throughout the test automation process of an application:

Automation Testing

1. Lack of Highly Skilled Test Automation Experts

  • The most fundamental reason behind lacking an automation testing process is the absence of highly skilled automation test engineers.
  • To design and maintain the test automation framework and test scripts, the test automation engineer needs to be skilled and have details knowledge about automation technical skills.
  • To create a test script correctly and sustain them, the team should implement the test scripts successfully to check the application performance and fix the technical issues.
  • To achieve the operative automation aspects, the automation test engineers should have strong knowledge about test automation frameworks because it would be easy for them to design and execute the test scripts.

2. Appropriate Selection of Right Test Automation Tool

  • The next challenge, we mostly face while performing the automation testing is selecting thecorrect automation testing tool.
  • A suitable detailed assessment of the application under test (AUT) is mandatory.
  • With the accessibility of various automation testing tools for both open-source and paid tools. And it is essential to check appropriately before accepting a tool.

3. Challenges with Scaling Test environments

  • It is a crucial challenge in present day as testing teams that don’t providing test environments in the cloud.
  • It is essential to quickly deliver the changed test environments that automated testing requires, measure them up, execute the tests, to make sure that the success while testing in the cloud.
  • Generally, the internal teams have a partial number of test environments which they can use to execute the fewer tests and deployed them at any given time.
  • As a result, testing takes a much longer time. To overcome this, it is essential to move test environments to the cloud to scale the test automation, and it will also reduce testing teams operating costs.

4. Including High Initial Investment Costs

  • Generally, the execution of the automation testing process in the initial phase is a bit expensive because it is necessary to evaluate, design, and build an automation testing framework, libraries, or reusable functions over a detailed AUT analysis.
  • Additionally, if an automation test engineer picks the licensed test automation tool, the operating cost should be appraised.
  • If the automation test engineer selects the open-source tools, then it should also be significant efforts spent on learning, training, and maintaining them.
  • Later, the selection of automation tools, either open-source or licensed, depends on the AUT priority and availability of cost facility.

5. Miscommunication and lack of collaboration between Development and testing teams

  • Miscommunication or lack of proper collaboration between the developer and the test engineers’ team and operations teams does not lead us to successful test automation.
  • Therefore, it is significant to place all the team (developer, testing, operation) members to categorize the test automation objectives and set targets.
  • To ensure the test automation success, these teams need to spend some time to get an effective communication and to get a clear understanding of the business needs and project specifications.

Automation Testing Tools
