Defined in:

Overview

Failure behavior - simulates service failure

Raises a SimulatedFailure error based on configured probability. This is useful for testing how applications handle service unavailability, timeouts, and other failure scenarios.

Examples:

Create with probability

failure = Failure.new(10, rng)  # 10% failure rate
failure.apply(result)  # May raise SimulatedFailure

Constructor Details

This class inherits a constructor from Synthra::Behaviors::Base

Instance Method Details

#apply(result, context = nil) ⇒ Object

Apply the failure behavior

Based on probability, either raises SimulatedFailure or returns the result unchanged.

Examples:

failure = Failure.new(10, rng)  # 10% failure rate
failure.apply({ "id" => "123" })
# Returns result 90% of the time
# Raises SimulatedFailure 10% of the time

Parameters:

  • result (Object) —

    the generated data

  • context (Generator::Context, nil) (defaults to: nil) —

    generation context (not used)

Returns:

  • (Object) —

    the result if no failure

Raises:
