Can we set a negative priority in TestNG?

As an experienced tutor registered on UrbanPro.com, I understand the nuances of TestNG priorities in automation testing coaching. Let's explore the concept of setting priorities, including whether negative priorities are permissible and how they impact test execution.

Introduction:

TestNG provides a powerful mechanism for setting priorities to control the execution order of test methods. This guide aims to clarify the possibility of setting negative priorities in TestNG and the implications for test execution.

Understanding TestNG Priorities:

**1. Definition and Purpose:

• Priority Attribute in TestNG:
  • TestNG allows the use of the priority attribute to define the execution order of test methods within a test class.

**2. Setting Positive Priorities:

• Ascending Order Execution:
  • Test methods with lower numeric priorities (e.g., priority = 1) are executed before those with higher numeric priorities.

**3. Can We Set Negative Priorities?

• Negative Priorities Not Permitted:
  • TestNG does not support setting negative priorities directly. Attempting to assign a negative priority may result in unexpected behavior or errors.

**4. Alternative Approach:

• Use of Dependencies:
  • While negative priorities are not supported, you can achieve similar control using test dependencies (dependsOnMethods or dependsOnGroups) to create a logical order of test execution.
