Struct TestContext 

pub struct TestContext {
    pub svm: Arc<Mutex<LiteSVM>>,
    pub rpc: RpcClient,
    pub payer: Arc<Keypair>,
}

Shared test context that bundles a LiteSVM instance, an RPC client backed by MockRpcSender, and a funded payer keypair.

Fields

svm: Arc<Mutex<LiteSVM>>

LiteSVM instance behind a synchronous mutex for shared access.

rpc: RpcClient

Non-blocking RPC client that dispatches to the same LiteSVM.

payer: Arc<Keypair>

Pre-funded payer keypair (1 000 SOL).

Implementations

impl TestContext

pub fn lock_svm(&self) -> MutexGuard<'_, LiteSVM>

Acquire the shared LiteSVM guard, panicking on poison.

A poisoned mutex means a prior test panicked mid-critical-section and the SVM state is no longer trustworthy, so failing fast is the right call for test infrastructure.
