class SimTest
Defined at line 251 of file ../../src/connectivity/wlan/drivers/third_party/broadcom/brcmfmac/sim/test/sim_test.h
A base class that can be used for creating simulation tests. It provides functionality that
should be common to most tests (like creating a new device instance and setting up and plugging
into the environment). It also provides a factory method for creating a new interface on the
simulated device.

zx_status_t PreInit ()In some cases (like error injection that affects the initialization) we want to work with
an uninitialized device. This method will allocate, but not initialize the device. To complete
initialization, the Init() function can be called after PreInit().

zx_status_t Init ()Allocate device (if it hasn't already been allocated) and initialize it. This function doesn't
require PreInit() to be called first.

void WaitForDeviceCount (uint32_t expected)We don't have a good mechanism to synchronize the Remove call from
brcmfmac::Device with node_server_, so these functions repeatedly check the device count and
sleep until the device count matches the expected value.
The result is a timeout if it doesn't work instead of immediately failing, but the upside is
that we're no longer relying on the timing of the Remove call.

void WaitForRecoveryComplete ()Wait for recovery to complete on the calling thread. Recovery happens on the driver dispatcher,
so this should never be called on the driver dispatcher. Doing so will deadlock the test.
Defined at line 733 of file ../../src/connectivity/wlan/drivers/third_party/broadcom/brcmfmac/sim/test/sim_test.cc
void WithSimDevice (fit::function<void (brcmfmac::SimDevice *)> )Provides synchronous access to the brcmfmac::SimDevice instance via a callback. The callback
is posted to the SimDevice's dispatcher (i.e., driver_dispatcher_).
This can only be called after PreInit().
Note that there is a risk of deadlock here: if SimDevice makes a sync call to
WlanFullmacImplIfc (which blocks driver_dispatcher_ until the call is complete), and we try to
call WithSimDevice from the WlanFullmacImplIfc handler, it will deadlock because
driver_dispatcher_ is blocked from the original sync call from SimDevice.
