Introduction

In today’s fast-moving software world, teams need to release applications quickly without affecting quality. But testing everything in detail is not always possible due to time and resource limits. This is where Risk-Based Testing (RBT) helps.

Risk-Based Testing focuses on testing the most important and risky parts of an application first. Instead of giving equal importance to all test cases, it helps teams decide what to test first based on risk.

What is Tricentis Tosca?

Tricentis Tosca is a test automation tool used for functional and end-to-end testing. It uses a script less and model-based approach, which means testers don’t need strong coding skills to create and maintain test cases.

It is widely used for:

• Functional testing
• Regression testing
• End-to-end business process testing

What is Risk-Based Testing?

Risk-Based Testing is a testing approach where testing is done based on risk level. A simple formula to understand risk:

Risk = Probability of Failure × Impact of Failure

• Probability → How likely a feature will fail
• Impact → How serious the issue will be if it fails

This helps teams focus on what really matters when time is limited.

Why Use Risk-Based Testing in Tosca?

Using Risk-Based Testing in Tosca helps teams:

• Focus on critical business features
• Save time and effort
• Improve testing efficiency
• Catch major defects early
• Make better release decisions

Instead of testing everything equally, teams test important features first.

Key Steps in Risk-Based Testing

1. Risk Identification

Identify high-risk areas such as:

• Complex workflows
• Payment modules
• Frequently used features
• Recently changed features

2.  Risk Assessment

Evaluate each feature based on:

• Probability of failure
• Business impact

3.  Risk Classification

Classify risks into:

• High
• Medium
• Low

4.  Risk Coverage

In Tosca, risk values are assigned to test cases, and teams track how much risk is covered during execution.

How Risk-Based Testing Works in Tosca

In Tricentis Tosca, Risk-Based Testing follows a structured approach:

1. Create test cases based on business scenarios
2. Assign risk values (Probability C Impact)
3. Tosca calculates Risk Priority Number (RPN)
4. Execute high-risk test cases first
5. Monitor risk coverage instead of just test count

This approach is very useful when there is limited time before it is released.

What We Do in Real-Time Projects (SAP & Salesforce)

In real projects, Risk-Based Testing is applied in a practical and structured way using Tosca.

Step 1: Understand the Business Process

We first understand the complete workflow.

• In SAP → Order-to-Cash (Order → Billing → Payment)
• In Salesforce → Lead-to-Opportunity (Lead → Conversion → Opportunity)

Step 2: Identify High-Risk Areas

We identify critical steps that impact business:

• SAP → Billing and Payment
• Salesforce → Lead Conversion

These are considered high risk because failures directly affect revenue or customers.

Step 3: Create Test Cases in Tosca

We design test cases for each business flow. Example:

• SAP → Validate billing and payment process
• Salesforce → Verify lead conversion and opportunity creation

Step 4: Assign Risk Values

Each test case is assigned:

• Probability of failure
• Impact (damage level)

Tosca calculates the Risk Priority Number (RPN) based on these values.

Step 5: Prioritize Test Execution

Test execution is done in order:

• High-risk → First
• Medium risk → Next
• Low risk → Last

Even if time is limited, critical functionality is always tested.

Step 6: Monitor Risk Coverage

Instead of counting test cases, we track:

• How much high-risk area is tested
• Whether critical flows are validated

Step 7: Report Results

We share results with stakeholders:

• Status of high-risk areas
• Risk coverage
• Any critical failures

This helps in making release decisions.

Real-World Example:

SAP (Procure-to-Pay Process)

In an SAP system, another important business process is Procure-to-Pay (P2P). This process is used when a company purchases goods or services from vendors.

It includes:

• Creating Purchase Requisition
• Creating Purchase Order (PO)
• Goods Receipt
• Invoice Verification
• Payment to Vendor

What We Do in Testing?

We first understand the complete purchasing flow and identify which steps are critical for business operations.

Why These Are High Risk

If invoice verification fails:

• Incorrect invoice amounts may be processed
• Financial errors can occur If vendor payment fails:
• Vendors may not get paid
• Business relationships may be affected
• Operations may get delayed

How We Apply Risk-Based Testing in Tosca

1. Create test cases for full Procure-to-Pay flow
2. Assign high risk to invoice and payment scenarios
3. Tosca calculates Risk Priority Number (RPN)
4. Execute high-risk test cases first
5. Then proceed with medium and low-risk scenarios

Outcome:

• Financial accuracy is ensured
• Vendor payments are validated
• Business operations run smoothly

Even if time is limited, the most critical financial processes are tested first.

Salesforce (Lead-to-Opportunity Process)

In a Salesforce application, a key business process is converting a lead into a customer. This flow includes:

• Creating a lead
• Converting the lead
• Creating an opportunity
• Managing account details

What We Do in Testing

We focus on the steps that directly impact sales and customer acquisition.

Risk Identification

1. High Risk

• Lead Conversion
• Opportunity Creation

2. Medium Risk

• Account Updates
• Contact Management

3. Low Risk

• Reports and Dashboards

Why These Are High Risk

If lead conversion fails:

• Potential customers are lost
• Sales team cannot proceed
• Business revenue is affected If opportunity creation fails Sales pipeline is broken
• No tracking of deals

How We Apply Risk-Based Testing in Tosca

• Create test cases for lead-to-opportunity flow
• Assign high risk to lead conversion scenarios
• Prioritize these test cases in Tosca
• Execute high-risk tests first
• Validate that opportunities are created correctly

Outcome

• Critical sales processes are validated first
• Business continuity is ensured
• Risk of losing customers is reduced

Conclusion:

Risk-Based Testing in Tricentis Tosca is a practical and efficient approach for modern software testing, where time and resources are often limited. Instead of testing all features equally, it helps teams focus on the most critical and high-risk areas, ensuring that important business functionalities are validated first. By identifying risks, assigning priorities, and executing high-risk test cases early, teams can reduce major failures and improve overall software quality.

Real-world use cases in SAP and Salesforce clearly show how focusing on key processes like payments, lead conversion, and case management helps prevent serious business impacts. Overall, Risk-Based Testing enables teams to work smarter, deliver faster, and release applications with greater confidence.
