	}),
	// ... other options
)

func WithCallsAllowedWithinModule added in v0.196.0

Any overrides provided by calling WhenVerb(...) will take precedence

func WithConfig added in v0.189.0 

func WithConfig[T ftl.ConfigType](config ftl.ConfigValue[T], value T) Option

WithConfig sets a configuration for the current module

To be used when setting up a context for a test:

func WithProjectFile added in v0.201.0 

func WithProjectFile(path string) Option

WithProjectFile loads config and secrets from a project file

Takes a path to an FTL project file. If an empty path is provided, the path is inferred from the FTL_CONFIG environment variable. If that is not found, the ftl-project.toml file in the git root is used. If a project file is not found, an error is returned.

func WithSubscriber added in v0.254.0 

func WithSubscriber[E any](subscription ftl.SubscriptionHandle[E], sink ftl.Sink[E]) Option

WithSubscriber adds a subscriber during a test

By default, all subscribers are disabled in unit tests, and must be manually enabled by calling WithSubscriber(…). This allows easy isolation for each unit test.

WithSubscriber(…) can also be used to make an ad-hoc subscriber for your test by defining a new function as the sink.

To be used when setting up a context for a test: 

ctx := ftltest.Context(
	ftltest.WithSubscriber(paymentTopic, ProcessPayment),
	// ... other options
)
