Struct TestFailure 

pub struct TestFailure {
    pub message: String,
    pub stack: Option<String>,
    pub diff: Option<String>,
    pub screenshot: Option<Vec<u8>>,
}

A test failure with diagnostic information.

Fields

message: String

stack: Option<String>

diff: Option<String>

screenshot: Option<Vec<u8>>

Screenshot on failure (auto-captured).

Implementations

impl TestFailure

pub fn wrap(prefix: impl Display, err: FerriError) -> Self

Wrap a ferridriver::FerriError with a contextual prefix while preserving the Playwright-style typed class name. The resulting message reads "<prefix>: <Name>: <message>" for distinguishable variants and "<prefix>: <message>" for unnamed ones, so consumers that match on TimeoutError: still see the marker after the prefix.

Trait Implementations

impl Clone for TestFailure

fn clone(&self) -> TestFailure

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TestFailure

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

Formats the value using the given formatter.

impl Display for TestFailure

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

Formats the value using the given formatter.

impl Error for TestFailure

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<&str> for TestFailure

fn from(message: &str) -> Self

Converts to this type from the input type.

impl From<AssertionFailure> for TestFailure

fn from(a: AssertionFailure) -> Self

Converts to this type from the input type.

impl From<FerriError> for TestFailure

Enables ? on any Result<T, FerriError> inside test functions after the migration to structured errors. Prepends the typed class name for the variants Playwright distinguishes (TimeoutError / TargetClosedError) so the TS bridge can re-hydrate a real class instance from the <Name>: <message> shape — same convention ferridriver-node::error::to_napi uses on the NAPI surface. Unnamed variants pass through verbatim.

fn from(err: FerriError) -> Self

Converts to this type from the input type.

impl From<String> for TestFailure

Legacy bridge: kept so test bodies that hand-build a String error (logging helpers, manual panic messages) keep ?-propagating through TestFailure. Locator methods now return Result<T, FerriError> and flow through the dedicated From<ferridriver::FerriError> impl below.

fn from(message: String) -> Self

Converts to this type from the input type.
