Risk based testing is procedure of giving priorities for features, functions and modules of application under test based on the impact of failures. It involves analysing risk based on the complexity, business criticality and visible areas.
Risk can be negative or positive.
- Positive Risks: It is referred to opportunities that help in business sustainability. For example, investing in new project changing new processes, developing new products.
- Negative Risks: It is referred as threats and recommendations to minimise or eliminate them must be implemented for project success.
The objectives of Risk based testing are:
- To know when and how to use risk based testing
- To understand advantages and disadvantages of risk based testing.
- To understand steps of implementing the risk based testing on appropriate application.
- To make risk free project using best practices in risk management to achieve a project outcome that balances risks with quality, features, budget and schedule.
Major processes to execute risk based testing are:
Process 1: Risk identification: It describes all the requirements in terms of risk involved in the project. The projects encounter various risks which are recognised by the stake holders of the projects. These are mix of technical and business team.
Process 2: Risk analysis, Risk exposure using mitigations, Test policy– It prioritises the requirements in terms of risk assessment, once all the possible risks and their impacts are analysed the project manager will get the requirements prioritised. The priority requirements should be agreed and updated in the functional document.
Process 3: Test plan– Planning and defining the tests according to requirement priorities. When we get the requirement with the priority. We can start the test activities by keeping priorities in mind.
Process 4: Test execution & result– executing the test according to priority and acceptance criteria. If any of the identified risks realised by the test schedule time then there is a chance of schedule slippage by the development side.
Advantages of Risk based testing:
- Improved quality– All the critical functions of the applications are tested.
- Giving more focus on the risks of the business projects rather than the functionality of the information system.
- It provides the negotiating instrument to the client and test manager similar when existing means are limited.
- Associate the product risk to the requirement identifies the gap.
- Testing will focus on the most important matters first with optimal test delivery, limited time, money and qualified resources. We need to determine the better way to accelerate our testing effort with still managing the risk of the application under test.
- Improve customer satisfaction by customer involvement, good report and progress track.
