Class Method Details

.property(*args, **kwargs, &predicate) ⇒ Property

Create a property-based test with arbitraries. To run the test, pass the returned value to ‘Pbt.assert` method. Be aware that using both positional and keyword arguments is not supported.

Examples:

Basic usage

Pbt.property(Pbt.integer) do |n|
  # your test code here
end

Use multiple arbitraries

Pbt.property(Pbt.string, Pbt.symbol) do |str, sym|
  # your test code here
end

Use hash arbitraries

Pbt.property(x: Pbt.integer, y: Pbt.integer) do |x, y|
  # your test code here
end

Parameters:

• args (Array<Arbitrary>) —

  Arbitraries to generate values. You can pass one or more arbitraries.

• kwargs (Hash<Symbol,Arbitrary>) —

  Arbitraries to generate values. You can pass arbitraries with keyword arguments.

• predicate (Proc) —

  Test code that receives generated values and runs the test.

Returns:

• (Property)
