class DatabaseConnectionResolver extends ConnectionResolver implements FlushableConnectionResolver

Database connection resolver for the testing environment.

Testbench needs stable bare connections across its setup, transaction, and assertion helpers. The resolver therefore retains each borrowed wrapper alongside its bare connection and explicitly discards both at teardown.

Constants

DEFAULT_CONNECTION_CONTEXT_KEY

Context key for per-coroutine default connection override.

Shared with DatabaseManager::usingConnection() to ensure all access paths respect the override.

Properties

protected string|null $default

The config-derived default connection name, captured at construction.

from  ConnectionResolver
protected PoolFactory $factory from  ConnectionResolver
protected PooledConnection> $nonCoroutineConnections

Pooled wrappers retained by non-coroutine task execution.

from  ConnectionResolver
static protected ConnectionInterface> $connections

Connections for testing environment.

static protected ConnectionInterface> $pooledConnections

Borrowed pooled wrappers that own the cached bare connections.

static protected int|null $containerId

The object ID of the container when connections were cached.

static protected bool $rebindingRegistered

Whether the dispatcher rebinding hook has been registered.

Parameters

Container $container

at line 174
ConnectionInterface connection(UnitEnum|string|null $name = null)

Get a database connection instance.

Creates connections through the pool factory and retains their owning wrappers until terminal test teardown.

Parameters

UnitEnum|string|null $name

Return Value

ConnectionInterface

in ConnectionResolver at line 149
void releaseConnections()

internal  
 

Release connections retained by non-coroutine task execution.

Return Value

void

in ConnectionResolver at line 163
void discardConnections()

internal  
 

Discard connections retained by non-coroutine task execution.

Return Value

void

in ConnectionResolver at line 179
string|null getDefaultConnection()

Get the default connection name.

Checks Context first for per-coroutine override (from setDefaultConnection() or DatabaseManager::usingConnection()), then falls back to the config-derived default captured at construction.

Return Value

string|null

in ConnectionResolver at line 191
void setDefaultConnection(string|null $name)

Set the default connection name for the current execution context.

Writes to coroutine Context so concurrent requests in the same Swoole worker are not affected. A null value clears the override and getDefaultConnection() falls back to the config-derived default.

Parameters

string|null $name

Return Value

void

in ConnectionResolver at line 203
protected string getContextKey(string $name)

Get the context key for storing a connection.

Parameters

string $name

Return Value

string

in ConnectionResolver at line 211
protected void terminateConnections(Closure $terminate)

Detach and terminate retained non-coroutine connections.

Parameters

Closure $terminate

Return Value

void

at line 72
static void resetCachedConnections()

Reset all cached connections to clean state for another setup phase.

Called after Application is created to prevent test pollution (query logs, event listeners, transaction state, etc.) from leaking between tests.

When the container changes (new test with fresh Application), cached connections are flushed since they hold references to the old container's services. A rebinding hook is registered so Event::fake() automatically updates cached connections with the new dispatcher.

Tests only. The cached connections are process-global, so runtime use can reset or discard a connection borrowed by another coroutine.

Return Value

void

at line 98
static void flushCachedConnections()

Discard all cached connections and clear resolver lifecycle state.

Tests only. The cached connections are process-global, so runtime use can discard a connection borrowed by another coroutine.

Return Value

void

at line 111
static protected void registerDispatcherRebinding(Container $container)

Register a rebinding hook for the event dispatcher.

When Event::fake() swaps the dispatcher, this callback updates all cached connections to use the new (fake) dispatcher.

Parameters

Container $container

Return Value

void

at line 135
protected string connectionCacheKey(string $name, DbPool|null $pool = null)

Resolve the cache key that owns the pooled wrapper.

Parameters

string $name
DbPool|null $pool

Return Value

string

at line 155
void flush(string $name)

Flush a cached connection.

Discard the owning pooled wrapper before clearing the bare connection.

Parameters

string $name

Return Value

void

at line 242
static protected void discardCachedConnections()

Discard every cached pooled wrapper.

Return Value
