Class Method Details

.apply!(app_name:, environment: DEFAULT_TEST_ENVIRONMENT) ⇒ Object

Configure the Langfuse module with a NullSpanExporter. Separate from ‘install!` so it can be invoked directly in specs that need to test SpecSupport itself, or by apps that drive their own lifecycle.

  PlatformSdk::Observability::Langfuse.configure(
    app_name: app_name,
    environment: environment,
    exporter: NullSpanExporter.new
  )
end

.exporter ⇒ Object

The currently-configured NullSpanExporter, or nil if ‘install!` was not called or the configuration was reset.

  config.exporter
end

.install!(app_name:, environment: DEFAULT_TEST_ENVIRONMENT) ⇒ Object

Register the RSpec lifecycle hooks. Call once from ‘rails_helper.rb` (or `spec_helper.rb`). The actual NullSpanExporter wiring happens in `before(:suite)`; this method just sets up the hooks.
