What is the test for screening a prisoner's complaint that seeks relief against a governmental entity, its officer or its employee?

A district court is required to screen a prisoner's complaint that seeks relief against a governmental entity, its officer, or its employee. See 28 U.S.C. 1915A(a). The court must identify any cognizable claims and dismiss any portion of the complaint that is frivolous or malicious, that fails to state a claim upon which relief may be granted, or that seeks monetary relief from a defendant who is immune from such relief. See 28 U.S.C. 1915A(b)(1), (2). The court must construe an unrepresented litigant's complaint liberally. Haines v. Kerner, 404 U.S. 519, 520 (1972) (per curiam).
