+    Test to verify the behavior of the simulation with a specific resolution.
+
+    This test sets up a simple network with an iaf_psc_alpha neuron and a
+    poisson_generator_ps. It simulates the network for a specified duration
+    to ensure that the simulation runs without assertion failures.
+
+    Previously, this script caused a C++ assertion to fail for h==0.1, but not
+    for h==0.01 or h==0.001. This test ensures that the issue is resolved.
