Function lambda_runtime_types::exec_test

pub fn exec_test<Shared, Event, Run, Return>(test_data: &str) -> Result<()> where
    Shared: Default + Send + Sync,
    Event: for<'de> Deserialize<'de> + Debug,
    Run: Runner<Shared, Event, Return>,
    Return: Serialize + Debug, 

This is supported on crate feature test only.

Lambda entrypoint. This function can be used to test one or multiple lambda invocations locally.

Types:

• Shared: Type which is shared between lambda invocations. Note that lambda will create multiple environments for simulations invokations and environments are only kept alive for a certain time. It is thus not guaranteed that data can be reused, but with this types its possible.
• Event: The expected Event which is being send to the lambda by AWS.
• Run: Runner which is execued for each lambda invocation.
• Return: Type which is the result of the lamba invocation being returned to AWS
