1. A testing system comprising:
a wellbore downhole shut-in device comprising:
a valve body comprising an inlet;
an inner sleeve coupled to an inner surface of the valve body, the inner sleeve movable from a closed position to an open position to allow a fluid flow from a wellbore through the inlet of the valve body and moveable from the open position to the closed position to stop the fluid flow through the inlet of the valve body;
an actuation mechanism coupled to the inner sleeve, the actuation mechanism operable to move the inner sleeve between the closed position and the open position;
a screen surrounding an outer surface of the valve body; and
a plurality of end caps configured to couple the screen to the valve body and the actuation mechanism; and
a strainer tool disposed within the screen of the wellbore downhole shut-in device between the valve body and an uphole end of the wellbore downhole shut-in device, the strainer tool comprising an internal strainer with a conical or frustoconical portion extending away from the valve body,
wherein the wellbore downhole shut-in device and the strainer tool define a flow path from the screen to the inlet of the valve body, and from the inlet of the valve body through the strainer tool to the uphole end of the wellbore downhole shut-in device.
