Errors that can occur during testing.

This enum covers all possible error conditions that can occur when using the testing utilities.

Examples

use durable_execution_sdk_testing::TestError;

// Operation not found
let err = TestError::OperationNotFound("my-step".to_string());
assert!(err.to_string().contains("my-step"));

// Type mismatch
let err = TestError::OperationTypeMismatch {
    expected: durable_execution_sdk::OperationType::Step,
    found: durable_execution_sdk::OperationType::Wait,
};
assert!(err.to_string().contains("Step"));

Trait Implementations

impl Debug for TestError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for TestError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for TestError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<DurableError> for TestError

fn from(source: DurableError) -> Self

Converts to this type from the input type.

impl From<Error> for TestError

fn from(source: Error) -> Self
