testSignal

fun testSignal(signal: Transmission.Signal, assertions: suspend TransmissionTest.TestResult.() -> Unit)

Executes a test with the given signal transmission and runs the provided assertions.

This method processes the signal through the configured router and captures all resulting data and effect streams for assertion. The assertions are executed with access to the captured streams through the TestResult receiver.

Parameters

signal

The signal transmission to test

assertions

Lambda with TestResult receiver for making assertions

Example usage:

transformer.test()
    .testSignal(UserSignal.Login("username", "password")) {
        // Assert successful login data
        val loginData = lastData<UserData.LoggedIn>()
        assertNotNull(loginData)
        assertEquals("username", loginData.user.username)

        // Assert login effect was published
        val loginEffect = lastEffect<AuthEffect.LoginSuccessful>()
        assertNotNull(loginEffect)
    }
