Identity function.

id x = x

The acceptable occurrence of false positives Example, Confidence 10^9 would mean that you'd accept a false positive for 1 in 10^9 tests.

Make sure that the result is statistically significant in accordance to the passed Confidence

The class of monoids (types with an associative binary operation that has an identity). Instances should satisfy the following:

• Right identity x <> mempty = x
• Left identity mempty <> x = x
• Associativity x <> (y <> z) = (x <> y) <> z (Semigroup law)
• Concatenation mconcat = foldr (<>) mempty

The method names refer to the monoid of lists under concatenation, but there are many other instances. Some types can be viewed as a monoid in more than one way, e.g. both addition and multiplication on numbers. In such cases we often define newtypes and make those instances of Monoid, e.g. Sum and Product. NOTE: Semigroup is a superclass of Monoid since base-4.11.0.0.

The acceptable occurrence of false positives Example, Confidence 10^9 would mean that you'd accept a false positive for 1 in 10^9 tests.

Is true when there exists a label that is sure to have failed according to the Confidence constraint

Is true when the test coverage satisfies the specified Confidence contstraint for all 'Coverage CoverCount's

The default confidence allows one false positive in 10^9 tests
