Test Cases For Automation Testing

Presently is the time of test case automation, as most of the testing projects are striving to translate their manual test cases to automated ones to enhance productivity and coverage. One of the crucial steps to begin Automation Testing is, choosing the right test case automation and defining the return on investment (ROI). 

In this blog, we will try to cite a few essential points to help you select the perfect candidate for automation and conclude various other factors that will produce better test results and advantages.

How to Select Correct Test Cases Automation Testing

Automation does not overshadow or replace Manual Testing but it complements it. Like Manual, Automation requires a technique with proper planning, monitoring, and control. Automation, when executed correctly, can become an asset to the team, project, and eventually to the institution.

Let’s look at why Automated Testing is good?

 There are various advantages of Automation testing; here are a few important to mention:

  1. Helpful to implement routine tasks like Smoke tests and Regression tests.
  2. Useful in formulating the Test data.
  3. Enables the execution of test cases, which include complex business logic.
  4. Good to enforce the cross-platform test cases like different OS, browsers, etc.
  5. Wonderful to execute the test cases, which are a bit tough to execute manually.
  6. When the number of iterations of the test case performances is not known.

At various times, stakeholders feel that test automation works as a support codeless test automation tools for Manual Testing, so it’s crucial to recognize that automation is an adequate way to boost the efficiency, effectiveness, and coverage of testing

It not only saves time but also improves accuracy, as repetitive assignments via the manual strategy can be prone to human mistakes and can be time-consuming. Automated testing efforts combined with cloud automation testing streamline quality assurance processes, enhancing efficiency and scalability in software development.

Candidates for Automation Should Avoid These Basic Mistakes that are Given Below:

One of the most common mistakes that testers make is 'NOT' selecting the appropriate test cases for automation. Choose a test suite carefully. Completely evaluate the test case automation and choose the candidates for automation based on the most important factor, ROI. 

We should grasp and learn how to attain a higher and more positive ROI early on. There is no fundamental mechanism for determining precise test cases for automation. It all depends on the application you're testing.

Steps to Select Right Automation Testing

Now let’s have a look at how To Select Correct Test Cases For Automation Testing:

Step 1: Recognize the parameters on which you will establish your test case as a candidate for automation. You can have your parameters depending on your application. Test cases are executed with different sets of data, browsers, own test automation environment, complex business logic, different sets of users, and large amounts of data. It requires special data.

Step 2: You should break each application into modules. You should analyze and try to recognize the test cases for each module, which should be automated based on the parameters. This list will vary from projects to projects and can also be improved to suit your requirements : Similarly, for all modules, this list can be utilized to recognize the automation candidate test cases.

Step 3: Consolidate and group the sum of test cases for each module.

Step 4: Once you have specified all the granular level features, you can illustrate them.

We should also take into account the below characteristics which form the basis of preventing the ROI:

  • Purchasing and licensing cost of the tool
  • Time to develop the scripts
  • Time to maintain the scripts.
  • Time and cost to train the resources.
  • Management overheads

Example of Test Automation ROI Calculation 

In most circumstances, ROI is evaluated for 5 years, but it’s not necessary. Based on the above components, let us try to explain the calculation of ROI for 5 years. As typical, you can always tailor and improve it.

ROI = Cumulative saving / Investment through automation *100

Manual To Automation Testing

When we try to automate a test suite these are some points which can become a big challenge: 

Automation Requirements:

  • Every testing team is different and has exclusive requirements for automation.
  • Altering standards to suit specific needs requires support from management and the development team.

Challenges of Automating Complex Applications:

  • Automating a 100% application is a monumental task that demands proper planning and monitoring.
  • The diverse permutations of data and environments with varying authentication attributes necessitate a strategic approach to automation.

Identifying Significant Test Cases:

  • Establishing standards to determine significant test cases is crucial.
  • Criteria may include complex business logic, risk-prone areas, and client interests.

Framework Formulation:

  • Developing the framework is paramount in automation.
  • More time should be devoted to framework improvement than scripting during automation planning.

You should ‘plan’ to design the framework. Recognize and make a checklist of the items which will form the framework. If the framework is rock solid, scripting and strengthening become manageable.

There are many other test automation frameworks available, each offering unique features and advantages tailored to specific project requirements.

  • Whenever we think of automation, we instantly jump to understand the programming language or scripting language. Learning this language will assist but the further emphasis should be on creating and developing logic.

Automation should not be the duty of a few handfuls of resources, fairly a full team should contribute towards it. This will enable not only to improve the skills of the resources but yet to keep them motivated.

  • Every tool has a norm to document the test results. To customize it is a difficult task. Reporting the test conclusions also requires coordination and maintenance which extends to the cost.
  • We should believe our automation stuff. We invest man-hours to create an automation suite, but still, we don’t trust in the test outcomes. Efforts should be provided to maintain the scripts. Furthermore, we should see that the team who is doing the manual testing of the application, should be involved to automate it as they understand their application.


Maximum of the time, a third-team does the automation so the real testing team is not familiar with the scripts and eventually ends up running the tests manually. In most of the cases, we like to Automate the Regression suite as it includes a bigger number of test cases. In that case, we can crack the regression suits into tinier suits and decide to run the proper suite as per the release requirement.
