What is Risk Based Testing? Top Benefits & Approaches

Nowadays, ‘Quality’ is becoming a crucial factor in software delivery, where continuous improvements are happening to improve the quality in order to keep the customers happy. However, how often have we seen risk based testing as part of a testing strategy or something that teams religiously do every sprint, during regression testing or any exploratory testing?

What is Risk Based Testing?

“Risk Based Testing (RBT) is a software testing type which is based on the probability of risk. It involves assessing the risk based on software complexity, criticality of business, frequency of use, possible areas with Defect etc.”

In terms of risks its not always negative risks, there can be positive risks too that one can test. 

  • Positive risks are referred to as opportunities and help in business sustainability. For example investing in a New project, Changing business processes, Developing new products.
  • Negative Risks are referred to as threats and recommendations to minimize or eliminate them must be implemented for project success.

What could be a Potential Risk to a Software?

In software testing, risks are the possible problems that might endanger the objectives of the project stakeholders. It is the possibility of a negative or undesirable outcome. A risk is something that has not happened yet and it may never happen; it is a potential problem.

When to Implement Risk Based Testing?

You can implement risk-based testing when:

  • There are resource, budget, and time constraints for the project.
  • You are performing security testing in cloud computing environments.
  • You need to conduct testing for projects with high-risk factors.
  • There is an ongoing process where the project is continuously changing.

Risk Management Process

Essentially, there are five stages of the risk management process. These sequential steps make up the basic framework you need to follow for managing risks in a project:

  • Risk Identification: Identify potential risks that could impact the project, considering sources such as requirements, design, technology, stakeholders, and external factors.
  • Risk Analysis: Assess the risks as per their occurrence, potential impact, and associated consequences, which helps in understanding the risk severity.
  • Risk Evaluation and Prioritization: Rank risks as per their likelihood and potential impact, thus focusing resources and efforts on addressing high-priority risks that pose significant threats.
  • Risk Mitigation: Develop strategies and plans to mitigate or control identified risks. This step involves risk avoidance, transfer, reduction, or acceptance, depending on the specific risk and project context.
  • Monitor and Review the Risk: Continuously monitor the risks throughout the project lifecycle. You can do so by implementing control measures, tracking risk status, and assessing the effectiveness of risk mitigation actions.

Besides these fundamental stages, you can also focus on the communication element while working on the risk management process. Following this structured process, organizations can proactively address and mitigate potential risks, thereby increasing the likelihood of project success.

How is Risk Based Testing Relevant to Agile and DevOps?

Risk-based testing is highly relevant to Agile and DevOps methodologies as it aligns with their core principles of iterative development, continuous integration, and rapid delivery. Here’s how risk-based testing relates to Agile and DevOps:

  • Agile and DevOps emphasize early and frequent feedback loops. Risk-based testing facilitates the identification of potential risks early in the development process, enabling proactive risk mitigation strategies.
  • Risk-based testing allows for iterative test planning and prioritization. Test teams can continuously assess and reprioritize risks, focusing on high-risk areas in each iteration or sprint.
  • Agile and DevOps often work under time and resource constraints. Risk-based testing helps optimize resource allocation by concentrating testing efforts on critical and high-risk functionalities, ensuring efficient use of limited resources.
  • Agile and DevOps promote cross-functional collaboration. Risk-based testing encourages involvement from different stakeholders, such as business analysts, developers, testers, and operations personnel, fostering effective communication and a shared understanding of project risks.
  • Risk-based testing provides a feedback mechanism for continuous improvement. Agile and DevOps teams can adapt their testing strategies and incorporate necessary adjustments into subsequent iterations as risks evolve, or new risks emerge.
  • In DevOps, continuous integration and continuous testing are vital for rapid and reliable software delivery. Risk-based testing guides the selection and prioritization of tests to be executed in the continuous testing pipeline, focusing on high-risk areas and critical functionalities.

Benefits Of Risk Based Testing:

Risk based testing comes with great benefits too such as:

  • – Increased customer focus: Risk-based testing emphasizes thorough tests on features that affect customers most directly, AKA higher risks. This directly improves business performance, reduces the probability of negative reviews, and generally minimizes the impact of each identified risk.
  • – Improved software quality: Risk-based testing focuses on finding higher risks first, and ensuring that the most important functions are tested first. Consequently, the software can be released with confidence in the fact that fundamental and customer-facing functions meet quality expectations.
  • – More structured testing: When risks are identified and their impact is quantified, it becomes easier to decide what to test, where to start, and stop testing. In other words, it becomes easier to define the scope of testing as well as test execution priority within limited timelines. This provides the structure needed to organize thousands of tests in every single development project.

Risk based testing may be a new topic for many teams, but the way to go ahead with this type of testing is by getting everyone in the team educated about its benefits and getting a buy-in. 

This blog will cover all the vital details of what risk based testing is and how you can approach this type of testing within your teams.

Risk in Testing

Risk in testing is more of a future event that we may or may not expect to happen in the application under test. Therefore it is vital we look into these risks and plan for them in advance so that we can eliminate the risk or reduce its impacts. Remember its far better to consider these risks rather than releasing an application full of risks, leading to bad reputation and increased costs of fixing. 

The risks can be managed by a test manager or someone senior, making sure these risks are mitigated/fixed as priority. Now the question that rises is, there may be quite a few risks, so should we pick all risks? The answer is yes, totally! Note down all risks, and according to its impact, time and resources these will be looked into. 

What do we do when a risk is identified?

  • Mitigate: This is when in advance you take steps to reduce the possibility and the impact of a risk.
  • Contingency: This is where a plan is put in place to reduce the possibility of the risk happening. 
  • Transfer: This is a step where you speak to team members/stakeholders about a potential risk or even accept the impact of the risk.
  • Ignore: Depending on the impact of a risk, if its a low risk and not much can be done, the risk can be ignored.

Risk Based Testing Approach

The best way to approach a risk within software testing is in the following manner:

  1. Prioritize a list of risks for your application.
  2. Focus on the areas of the application that you know could lead to a high risk and impact business (for example, could lead to a failure in production). 
  3. Perform exploratory testing on each risk to gain more understanding
  4. Risks will come and go, make sure to focus on the current list of risks and not to derail

It is always a good idea to focus on identifying defects early rather than later as it allows time to fix them sooner. Also, in terms of the application one can learn if its a fail-fast project with no value add and then to not spend more time on it. As we are aware, for the entire project team its vital to showcase value to a customer and make sure the application will provide a smoother experience and not a buggy experience. Therefore the steps above are quite useful to be within your testing strategy.

Another way to mitigate risks is by the following process:

Risk based testing approach

Risk Identification

This is actually the first ever step for a risk based testing approach to identify any potential risks whether high/medium/low. In this stage you can identify, categorize and sort the risks that pose great risk and prioritise the risk(s).

Risk Analysis

Once you know what the potential risks are from the identification stage, you can then start analysing the high impacting risk(s). This is more a team exercise where all can discuss and understand the likelyhood and the consequences of the risk. You can also calculate something known as the exposure to this risk to the application and the customer. In this step you would have identified which risks actually pose great risk to the organisation. Its a good idea to shift risk based testing to the left!

Risk Response 

Once you have identified and anaylised the risk(s), it’s a good idea to know how to respond to the risk(s). What needs to happen in this stage is some testing of the risks and choose the most effective testing technique. It’s a vital stage as you would need to choose the most effective and efficient way to test the risk. This is where some financial costs will be thought of, with regards to this risk. 

Test Scoping 

This is the review stage just before the testing can commence. Here the decisions on – scope of test, budget for testing and individual(s) availability and responsibilities – will be taken. 


Once the scope is designed and budgets have gone through, the testing can commence. 

In order to be financially effective, testing needs to strictly follow the scope and budget set out in the previous steps of the process. After this step is completed, the process can begin again as new code, features, and functionality are added to the app. 

Once you know there are certain areas that are more risky, regularly executing tests on them is recommended. And one solution that should be implemented is automating the regression tests for your most important functionalities. Here, choosing the right tool matters.

Risk Based Testing Examples

Risk Based Testing Examples

Let’s look at an everyday example, many people who catch a cold in the course of their lives and can catch a cold more than once in a year for instance. However a healthy individual may not struggle much with symptoms, therefore the risk associated with those individuals is pretty low.  But someone who is not looking after their health or say someone quite elderly may find it very difficult to fight the symptoms, therefore the associated risk is higher. So this basically means that with every risk there is a classification of risk we need to do. You can also divide the risks into product risk and project risk. 

A product risk is one which is related to a risk produced by work such as things we test. A project risk is according to the work carried out, such as the project. 

Some examples include:

Data risks, things such as how accurate the data is, how much data there is, the data types, consistency, data creation/updates/deletion, error handling. Furthermore, when we think about apps we test on a mobile, we can think about what takes the app to make the mobile battery run down, the connectivity for the app to fully work, operating system settings and so many more.

Checklist for Risk Based Testing

Risk-based testing requires careful consideration of various factors to effectively identify, prioritize, and mitigate risks. Here’s a checklist of factors to consider when performing risk-based testing:

  • Identify potential risk areas related to project scope, complexity, technology, and requirements.
  • Understand and underline the functionalities that greatly impact any financial aspects within the system.
  • Assess the impact of each risk on project objectives, timelines, and customer satisfaction.
  • Carefully prioritize the risk areas based on the complexity and features of the product.
  • Focus on requirements and design documents that can lead to building poor software with security issues.
  • Create tests that include risk analysis and risk-based cases.
  • Ensure that the test cases are scalable as new security features or functions add to the system.
  • Compare the current system against a similar kind of past system to assess where you need to give extra attention to risk identification and mitigation.
  • Allocate appropriate resources for testing high-priority risks.

Risk Based Testing Results Reporting and Metrics

Both reporting and analyzing metrics play a crucial role in providing stakeholders with valuable insights into the risks identified, their impact on the project, and the effectiveness of risk mitigation strategies. These reports and metrics help make informed decisions, prioritize actions, and ensure project success.

Include these points in your test results reporting:

  • Number of tests created/executed
  • Number of test cases with pass and failed status
  • Defect identification and their severity
  • Number of closed and open defects
  • System downtime
  • Test summary and the test coverage report

Metrics represent combined measurements, comparing software processes, projects, and products.

The Metrics include:

  • Productivity of the test cases
  • Efficiency of risk identification and mitigation
  • Test case efficacy
  • Test case coverage
  • Test design coverage
  • The associated cost of quality
  • Defect leakage
  • The efficiency of defect detection


A risk-based testing approach is a practical approach to follow within teams. Identifying risks at an earlier stage of software development also saves a lot of time, effort and costs which could be impeded otherwise when marketing the product as well as take the team away from achieving their goals of a good quality product.

It is always a good idea to shift testing to the left and especially risk based testing as its a great idea to think about risks sooner rather than later. Risk-based testing has many advantages as you have seen above including productivity and cost-efficiency, faster time to market and detailed information on test coverage. So would you rather risk it or think of this approach in advance?

Frequently Asked Questions

What is the risk in software testing?

Risk in software testing means an element or an action that might produce undesirable results. It is something yet to come to light (or may never become visible) but can make the system fragile and prone to failure or defects.

What are the different types of risks?

There are two types of risks: positive and negative. The former consists of options that improve software stability and sustainability. The latter refers to threats that need to be removed to secure the system.
