Steps to improve ROI


Case study






In Agile software development, test automation has evolved as a critical component of the continuous delivery of software. As greater automation test coverage gives stakeholders more accurate information of stability of high-value business features of their application and business. This will, in turn, help them in making more informed decisions at the business level. To understand if test automation will be a success or not, ROI will help to get insights.
Though the business decision-makers agree that test automation is a good idea but would not commit appropriate resources as they are uncertain about the costs of automating and maintaining a test automation framework and scripts. There will also be no transparency on the budget required, timelines to expect, and the value that it will deliver.
To get a buy-in from all the stakeholder, ROI measurement will help where business decision-makers can better understand the value that test automation delivers over time, and technical team members would get insights into the effects of what is required, the parameters involved, test life cycle timelines, robustness, and maintainability of the test framework and scripts. With this, both categories of users can use ROI as a tool to drive right decision making, leading to highly efficient test automation.This paper talks about the below

Return on investment (ROI) can be defined as a metric used to calculate the efficiency of any investment. If this is applied to test automation projects, it will depict how many cycles of execution is required to achieve the breakeven point and from when there will be positive returns from the investment. This can also be computed before starting the project to understand the wait time to achieve breakeven point, and whether there are any aspects to improve ROI etc. Usually, regression scenarios would be automated as during regression testing testers would need to work with huge data sets and on multiple browsers etc. The test automation ROI helps in finding out whether the shift to automation is worth performing.
The effort for manual testing along with the parameters (discussed in detail in further sections) have to be compared with the effort taken with the help of an automation tool. Using these efforts, the ROI for both cases can be checked and a decision arrived at.
Why should we measure ROI?

Why should we measure ROI?

Measuring anything will help us in identifying the efficiency and control it. Without measuring, nothing can be planned or controlled. Moving to Test automation ROI, it’s a key performance indicator in understanding the profitability of the investment. Also, how and by when it reduces the cost as time progresses.
Calculating return on investment (ROI) on automation project will help determine:
  • A simple approximation of cost
  • The types of automation for the project
  • The tools required
  • Level of skill required for the testing resources for the project
  • Whether effort that is put in is justified
  • The planning process for the project
  • The strategies to follow to maximize their return
How should we measure ROI?

How should we measure ROI?

Identify the activities related to Test environment setup, Test development, Testing, Maintenance phases. Identify the effort required for each activity. Effort can be easily converted to cost by calculating the cost of each resource Using the formula mentioned, cost savings for each cycle can be computed
Steps to improve ROI

Steps to improve ROI

  • Right scope:Identify the high-priority business scenarios that are repetitive tests instead of automating everything. The simplest way is to start with Smoke suite and then move to regression suite. Also, ensure that there is no complexity or dependency on other systems or hardware as automating and executing them might not always be feasible and may impact the estimates.
  • Right test design: All the tests that are considered for automation should be end-to-end scenarios that have good code coverage. Such scenarios would help in reducing the number of tests and time to execute.
  • Right test data: The test data that is used is also critical. It is comprehensive and relevant that can match the end user’s data. Different data sets can be created for valid, invalid and boundry conditions. This data should be verified before every major release to check its relevance.
  • Right plan for execution and maintenance: Once the test scripts are created, there should be a proper plan to execute and maintain them on a regular basis instead of pushing to execute just for a release. If these are executed frequently, the issues can be found early in the cycle, code issues can be fixed, and code changes for the application enhancements can be done early which is critical in identifying defects in the application
  • Right coverage: If the application has to be tested across multiple platforms or browsers or devices, it is advisable to select a cloud-based testing platform that provides different combinations of these This will help in reducing the cost of infrastructure, increase the coverage and improve test effectiveness
  • Right automation framework: An automation framework is said to be an effective one if it provides the below features:
    • Ease of use: Framework should provide a set of reusable keywords that would enable the engineer to consume them and write an automated script.
    • Scalable: It should aim at being scalable and reduce maintenance efforts in a world of demanding business needs, evolving requirements, changing technology interfaces and people
    • Cross browser testing: The scripts that are developed using this framework should work with all the leading browsers. User who has scripted with Chrome browser should be able to execute on Firefox or Internet Explorer with just change in Run settings.
    • Data-driven testing support: User should be able to change the data easily without going into any technical details. Framework should provide an option to execute the same script with different test data inputs.
    • Good and flexible reporting mechanisms: The execution reports should be easy to understand with complete details like the steps performed, test data used, the verifications points, and most importantly, screenshots for the failed steps.
    • Build and use reusable components: User should be able to combine a few keywords and create a new reusable keyword that can be used in different test scenarios.
    • E-mail notifications: Once the execution is completed, stakeholders have to be notified with an email that can include the details of the modules, test scripts, and run settings.
    • Provisioning of Batch Runs and Scheduling: User should be able to create batches with different sets of run settings or modules or test scripts and also schedule them to execute at a specific time.
    • Easily integrate with CI tools: User should be able to integrate the framework easily with any of the CI tools to achieve continuous testing along with the development
Case study

Case study

We have worked on a project where we started from developing the framework using open-source tools by integrating open-source external report into the tool. Over a period of 3 years team has developed 1600+ scripts and are maintaining them. These test scripts are executed for every sprint which is 14 days in duration. And these scripts are also executed for ad hoc release request
Calculating ROISince ROI is a unitless number, it really does not matter whether the savings and investment amounts are in dollars or time. For ease in calculation, hours will be used because most of our inputs are in the form of time.
Case study
Before we actual start calculating the ROI, we need to consider all the facts/tasks which effects the ROI.Here we would like to segregate all facts/tasks in 3 different areas mentioned below
  • Initial time for development setup
  • Actual Development time
  • Monitoring and Maintenance time
Initial time for development setupThe pre-phase of the development activity involves parameters like setting up the automation tool, setting up different environments, exploring the applications, time spent for initial data setup etc.

Cost Savings Savings is the difference between the cost of running a set of tests manually versus running the same tests automatically several times over some period.

Over 3 years, 72 regression run cycles we gain around 2000+ hours when compared to manual testing

Let us consider another scenario, where after one year, the project ended or the test automation framework is abandoned; in either case,case, it would have been more cost-effective to go with manual testing.



ROI metric is important to get visibility on the success of test automation even before we start it. Hence this will help in making strategic decisions.
