wisp-deployment-testing

This module provides a FakeEnvironmentVariableLoader as an implementation of the EnvironmentVariableLoader to use in tests to set Fake environment variables. Ideally, you should not use this package in any production code, but for test purposes only.

Also see wisp-deployment.

Usage

val environmentVariableLoader: FakeEnvironmentVariableLoader = 
  FakeEnvironmentVariableLoader(
    mutableMapOf(
      "ENVIRONMENT" to "Staging",
      "FOO" to "Bar"
    )
  )

val deployment = getDeploymentFromEnvironmentVariable(
  environmentVariableLoader = environmentVariableLoader
)

if (deployment.isStaging) {
  // this path will be executed
}

// foo will be "Bar"
val foo =   environmentVariableLoader.getEnvironmentVariable("FOO")

// Unknown env var will throw IllegalStateException
val unknown = environmentVariableLoader.getEnvironmentVariable("Unknown")

// Unknown env var with a fallback value will return fallback instead of throwing IllegalStateException
val unknownWithDefaultFallback = environmentVariableLoader.getEnvironmentVariable("UNKNOWN", "FALLBACK") // "FALLBACK"
