Difference between Use Case and Test Case

Use Case

Use case describes someone interact with software/system to achieve certain goal.
It is defined in business requirement document before coding.

Test Case

Test case refers to detail test description written to guide tester completing testing execution in order to determine whether the function under testing pass or fail, it contains the following:

test case ID
test description
Pre-conditions
Test steps
Expected outcome
Compatibility
and etc.

When asking the question, what the difference between use case and test case, the answer can be:

1. Use case and test case are developed at different stage:
    Use case is developed at beginning when Business Analyst analysis customer requirement and summarize up with use case and use diagrams to describe functions required.
    Test case is designed by testers after test plan is approved by stakeholders.

2. User case and test case are for different audience.
    Use case is written for customer, client, managers, business analysts.

    Test case is mainly written for developers and testers.

noun
  1. 1.

In the electrical world, digital signature servers the purpose of non-repudiation which ensure the document is electronically signed by the person and he/she will not be able to deny the that signature.

In the testing area, non-repudiation is one of the principles tester verify in security testing.

Regression Testing

Explain:
Simply speaking, regression testing refers to verifying existing functions do not get affected by implementing new function/features in the system.

Difference between regression testing and retesting.

Re-testing means to test again of particular part of the system when previous defect was rectified by developer at the same place, ensuring the defect is indeed fixed.

Regression testing is done to find out any issues might bring when new modifications or changes have been done to the system.
