I think you are an incredible educator...thank you for sharing your gift...I appreciate everything you have made so much easier for me.

[@NoniAyanna]

This was so helpful. I fully understand how to create and make sense of decision table testing. I wish you were my teacher! Thank you again.

**Notes: Decision Table Testing in Software Testing - Software Testing Tutorial #36**
**Introduction:**
- Decision Table Testing, also known as Cause-Effect Table Testing, a crucial black-box testing technique for scenarios with multiple conditions.
**Example: The Registration Portal Scenario:**
- A registration portal with three mandatory fields: Name, Email, and Address.
- The goal is to test the portal's success and error messages based on input values.
**Creating the Decision Table:**
- Use tools like Excel or Confluence to create a Decision Table.
- Three input fields: Name, Email, and Address, resulting in eight possible combinations.
**Decision Table Breakdown:**
- **Scenario 1:** Name (Y), Email (Y), Address (Y)
- Success Message: User should receive a success message.
- Error Message: None.
- **Scenario 2:** Name (N), Email (Y), Address (Y)
- Success Message: None.
- Error Message: "Name missing."
- **Scenario 3:** Name (Y), Email (N), Address (Y)
- Success Message: None.
- Error Message: "Email missing."
- **Scenario 4:** Name (Y), Email (Y), Address (N)
- Success Message: None.
- Error Message: "Address missing."
- **Scenario 5:** Name (N), Email (N), Address (Y)
- Success Message: None.
- Error Message: "Name and Email missing."
- **Scenario 6:** Name (N), Email (Y), Address (N)
- Success Message: None.
- Error Message: "Name and Address missing."
- **Scenario 7:** Name (Y), Email (N), Address (N)
- Success Message: None.
- Error Message: "Email and Address missing."
- **Scenario 8:** Name (N), Email (N), Address (N)
- Success Message: None.
- Error Message: "Name, Email, and Address missing."
**Executing the Tests:**
- Each scenario represents a specific test case.
- Test each scenario with corresponding inputs and verify expected outcomes.
- Error message text should match business requirements or specifications.

Hi Manish, greetings from Germany, amazing explanation can you elaborate how to reduce the test cases which has same output . Do you any example of collapsing the decision table thank you :)

[@sravansran2109]

hey kauser, in above example there are 3 conditions (name, email, address) then we conclude that there 8 possisble outputs (2^3=8), here 2 is sucessful message and error message (true/false)... In nutshell we can't reduce the output (test cases), for sure we need to test all the 8 testcases
if it helpfull give me like..😊

[@ariana_1343]

How did you determine 8 columns are required?

[@stephanieprolixity]

@@sravansran2109 ​ So, you just put 2 ^ of the number of however many conditions are defined and that’s how you verify how many combinations your table should display to make sure you covered everything?

[@ismailolalekan8160]

Yes

[@veliromn]

could you explain why 8 columns? There was no explanation for that...

[@sait5489]

There are 3 input conditions, Name, email, address, so there will be 2 power 3 . I.e 8columns will come. If there are 2 input conditions, 2 power 2 I.e 4 columns will come
