Not following. Open both the test1.lsp * test2.lsp files in VLIDE. Then set a break-point on the load line in test1.lsp, reload the test1.lsp (even if it was loaded previously it simply loads the new version). Now VLIDE will stop at the point where it starts loading test2.lsp.
Alternatively, if you simply want to debug test2, then just set a break-point at the 1st open parenthesis and load it through VLIDE. It should stop and allow you to step using F8, showing what's occurring during a load.
