Struct TestDatabase 

pub struct TestDatabase { /* private fields */ }

The database of a test, held in memory, every name being looked up regardless of its case, as Databaseds does.

Besides answering the commands of the database device, it records them, see Self::log, and can be made to fail some of them, see Self::add_fail, which is what testing how a server or a client copes with its database takes.

Implementations

impl TestDatabase

pub fn log(&self) -> Vec<(String, Value)>

Every command answered so far, in order, with its argument, those that failed included.

pub fn clear_log(&self)

Forget every command answered so far, see Self::log.

pub fn add_fail( &self, name: &str, err: impl Fn() -> Error + Send + Sync + 'static, )

Fail every command of that name from now on, with the error that makes, as a broken database does, until Self::remove_fail.

pub fn remove_fail(&self, name: &str)

Answer the commands of that name again, see Self::add_fail.

pub fn command(&self, name: &str, input: Value) -> Result<Value>

Answer a command of the database device.
