+# This file is part of the WarpX automated test suite. It is used to test the
+# injection of a laser pulse from an external binary file.
+#
+# - Generate an input binary file with a gaussian laser pulse.
+# - Run the WarpX simulation for time T, when the pulse is fully injected
+# - Compute the theory for laser envelope at time T
+# - Compare theory and simulation, for both envelope and central frequency
