From cf45afba61e1d3930db20c4b1d7021271c4a7f2f Mon Sep 17 00:00:00 2001 From: Christopher Chedeau Date: Fri, 23 Dec 2016 19:31:38 +0000 Subject: [PATCH] Add testing - This brings in the flow test suite that contains a ton of JavaScript parsing edge cases - This creates snapshot tests using the pretty printer for all of them - If uncomment `RUN_AST_TESTS` line in `tests/run_specs.js`, it checks ast(pretty_print(x)) == ast(x). Right now, "178 failed, 197 passed, 375 of 377 total". So half of the tests are not passing, most of them are crashes and many of the rest are subtle issues. --- package.json | 15 +- .../abnormal/__snapshots__/jsfmt.spec.js.snap | 127 +
