Type Alias: OneOfConstraints

OneOfConstraints = object

Defined in: packages/fast-check/src/arbitrary/oneof.ts:51

Constraints to be applied on oneof

Remarks

Since 2.14.0

Properties

depthIdentifier?

optional depthIdentifier?: DepthIdentifier | string

Defined in: packages/fast-check/src/arbitrary/oneof.ts:87

Depth identifier can be used to share the current depth between several instances.

By default, if not specified, each instance of oneof will have its own depth. In other words: you can have depth=1 in one while you have depth=100 in another one.

Remarks

Since 2.14.0


depthSize?

optional depthSize?: DepthSize

Defined in: packages/fast-check/src/arbitrary/oneof.ts:70

While going deeper and deeper within a recursive structure (see letrec), this factor will be used to increase the probability to generate instances of the first passed arbitrary.

Remarks

Since 2.14.0


maxDepth?

optional maxDepth?: number

Defined in: packages/fast-check/src/arbitrary/oneof.ts:78

Maximal authorized depth. Once this depth has been reached only the first arbitrary will be used.

Default Value

Number.POSITIVE_INFINITY — defaulting seen as "max non specified" when defaultSizeToMaxWhenMaxSpecified=true

Remarks

Since 2.14.0


withCrossShrink?

optional withCrossShrink?: boolean

Defined in: packages/fast-check/src/arbitrary/oneof.ts:62

When set to true, the shrinker of oneof will try to check if the first arbitrary could have been used to discover an issue. It allows to shrink trees.

Warning: First arbitrary must be the one resulting in the smallest structures for usages in deep tree-like structures.

Default Value

false

Remarks

Since 2.14.0
