withPollInterval

public CloudDurableTestRunner<I,O> withPollInterval(Duration interval)

Returns a new runner with the specified poll interval between history checks.

withTimeout

public CloudDurableTestRunner<I,O> withTimeout(Duration timeout)

Returns a new runner with the specified maximum wait time for execution completion.

withInvocationType

public CloudDurableTestRunner<I,O> withInvocationType(software.amazon.awssdk.services.lambda.model.InvocationType type)

Returns a new runner with the specified Lambda invocation type.

run

public TestResult<O> run(I input)

Invokes the Lambda function, polls execution history until completion, and returns the result.

startAsync

public AsyncExecution<O> startAsync(I input)

Start an asynchronous execution and return a handle for incremental polling. Use this for callback-based tests where you need to interact with the execution while it's running.

Parameters:

input - the input to the function

Returns:

execution handle for polling and inspection

getOperation

public TestOperation getOperation(String name)

Returns the TestOperation for the given name from the last execution result.
