Enum TestError 

#[non_exhaustive]
pub enum TestError {
    Connection(String),
    Request(Error),
    Mcp {
        code: i64,
        message: String,
    },
    ToolError(String),
    Assertion(String),
    Timeout(String),
    ElementNotFound(String),
    VisualRegression(String),
    Other(String),
}

Errors that can occur when interacting with the Victauri MCP server from tests.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Connection(String)

Failed to connect to the Victauri MCP server at the expected port.

Request(Error)

An HTTP-level error occurred during an MCP request.

Mcp

The MCP server returned a JSON-RPC error response.

Fields

code: i64

JSON-RPC error code.

message: String

Human-readable error message from the server.

ToolError(String)

A tool call returned isError: true in its result.

Assertion(String)

A test assertion evaluated to false.

Timeout(String)

A wait_for condition did not become true within the allowed time.

ElementNotFound(String)

An element matching the given criteria was not found in the DOM snapshot.

VisualRegression(String)

A visual regression was detected — screenshot differs from baseline.

Other(String)

A catch-all for errors that don’t fit other variants (IO, encoding, etc.).

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<Error> for TestError

fn from(source: Error) -> Self

Converts to this type from the input type.
