Tests of QCD in W and Z Production at Tevatron

We present measurements of the production cross sections times leptonic branching fractions and the transverse momentum distributions of $W$ and $Z$ bosons in $p\bar{p}$ collisions at $\sqrt{s}=1.8$ TeV using data collected with the D{\O}detector at the Fermilab Tevatron $p\bar{p}$ collider. A preliminary measurement of the $W$ charge asymmetry is also presented.
