Implementations

impl TestCase

pub fn take_flag(&mut self, arg: &str) -> Result<bool, DataDrivenError>

Extract the given flag from the test case, removing it. Fails if there are any arguments for the value. Returns true if the flag was present.

pub fn take_arg<T>(&mut self, arg: &str) -> Result<T, DataDrivenError>

where T: FromStr, <T as FromStr>::Err: Error + Send + Sync + 'static,

Extract the given arg from the test case, removing it. Fails if there isn’t exactly one argument for the value.

pub fn try_take_arg<T>( &mut self, arg: &str ) -> Result<Option<T>, DataDrivenError>

where T: FromStr, <T as FromStr>::Err: Error + Send + Sync + 'static,

Extract the given arg from the test case, removing it if it exists.

pub fn take_args<T>(&mut self, arg: &str) -> Result<Vec<T>, DataDrivenError>

where T: FromStr, <T as FromStr>::Err: Error + Send + Sync + 'static,

Extract the given args from the test case, removing it. Returns an error if the argument was not present at all.

pub fn try_take_args<T>( &mut self, arg: &str ) -> Result<Option<Vec<T>>, DataDrivenError>

where T: FromStr, <T as FromStr>::Err: Error + Send + 'static,

Extract the given args from the test case, removing it.

pub fn expect_empty(&self) -> Result<(), DataDrivenError>

Trait Implementations
