# testRecipe (/docs/api/core/functions/testRecipe)



```ts
function testRecipe(
   judge, 
   recipe, 
   fixtures, 
   options?
): Promise<TestReport>;
```

Fires every Fixture through the Judge at once and lets the Judge's gate meter concurrency.
The first `JudgeError` or `JudgeExhaustedError` aborts the rest and is rethrown: a partial
accuracy is worse than none.
