where F: FnOnce() -> R,

Run a contract method against this mock environment under a readable label, returning its result.

This is the unit / logic testing layer: f invokes your contract method natively (host execution) so it reads/writes this environment’s mock storage and runtime. name/args document the call and appear in failure diagnostics; they do not dispatch (native Rust calls are type-checked directly).

To execute the translated NeoVM bytecode on a real VM instead — the equivalent of Solana’s solana-program-test — use the neo-vm-test crate’s Contract::compile(..).invoke(..).

pub fn deploy(&mut self, script: &[u8], manifest: &[u8]) -> TestResult

pub fn update(&mut self, script: &[u8]) -> TestResult

pub fn update_with_manifest( &mut self, script: &[u8], manifest: &[u8], ) -> TestResult

pub fn destroy(&mut self) -> TestResult

pub fn is_deployed(&self) -> bool

pub fn deployed_script(&self) -> Option<&[u8]>

pub fn deployed_manifest(&self) -> Option<&[u8]>

pub fn reset(&mut self)

impl Default for TestEnvironment

fn default() -> Self
