Example 1
- 18 pass
- 24 plan
Test coverage: 75%
The calculator uses the numbers you enter. With 18 pass, 24 plan the result is Test coverage: 75%. This is not a model certificate.

How it works
Robustness in this calculator is passed tests as a share of the plan. With 18 pass, 24 plan the result is Test coverage: 75%.
coverage = min(100, 100 × min(pass, plan) / plan). The formula uses tests and plan.
Test coverage: 75% is not a model certificate. Another set of numbers gives Test coverage: 91.7%, and a further set gives Test coverage: 33.3%. Empty optional fields do not change the result.
API exposure answers a different question. Fairness gap does too. Here 18 pass, 24 plan leave Test coverage: 75%.
Type 18 pass, 24 plan and click Calculate. Two more ready sets sit under the form: Test coverage: 91.7% and Test coverage: 33.3%.
Other numbers on the same labels move the result. The first example gives Test coverage: 75%.
Formula
coverage = min(100, 100 × min(pass, plan) / plan).
How to use
- Type 18 pass, 24 plan.
- Leave optional fields empty if you do not want them in the result.
- Click Calculate. This set shows Test coverage: 75%.
- The second example under the result is Test coverage: 91.7%, the third Test coverage: 33.3%.
- This is not a model certificate.
Robustness = Test coverage: 75%
The calculator uses the numbers you enter. With 18 pass, 24 plan the result is Test coverage: 75%. This is not a model certificate.
- Robustness
- Robustness is this calculator's result. The first example is Test coverage: 75%.
- tests

Common questions
What do you get from 18 pass, 24 plan?
Test coverage: 75%. This is not a model certificate.
What about the second example?
Test coverage: 91.7%.
What about the third example?
Test coverage: 33.3%.
Is Test coverage: 75% a model certificate?
No. It is the result from the numbers you enter.
Do empty fields change Test coverage: 75%?
No. Empty optional fields do not change the result.
How is this different from API exposure?
That calculator answers another question. Here Robustness stays at Test coverage: 75%.
Does a comma in the number work?
Yes. A comma and a dot mean the same in a number field.
Is the result a diagnosis or official opinion?
No. The result comes from the numbers you enter. a model certificate sits outside this calculator.
Do 22 pass, 24 plan give Test coverage: 91.7%?
Yes. That is the second example under the form.
How is test coverage calculated?
The calculator divides the smaller of passed and plan by plan, multiplies by 100, and does not go above 100. In the first example the result is Test coverage: 75%.
What if passed exceeds the plan?
Coverage stays at 100. Extra tests do not raise the result above one hundred percent.
Is this a model certificate?
No. The result is a ratio of two numbers you enter. The calculator is not a model certificate and does not run tests.
Does 75% coverage mean the model is robust?
No. The result only shows passed tests as a share of the plan. The calculator does not grade test quality or model behavior.
