* Autogenerate tests to make sure startLine and startColumn work everywhere. Also improve the performance of tests so that the fact that we have ~88,000 tests now doesn't really cause the tests to run any slower. * Only deserialize JSON files that are serialized. * Don't fuzz test in node 8, since for whatever reason Jest 23 on node 8 takes forever after a certain number of tests, even if those tests are empty. * Rename runFixtureTests.js to run-fixture-tests.js. * Fix for showing code snippet again. * Fix some linter errors. * Fix stack traces and only generate the context error when we need it. * Create errors in deserialization step instead of using adjust to convert them. * Fix only storing cause if it's an error. * Fix UnexpectedSuccess error. * Better DifferentError and cleaned up the cause stuff a bit. * Fix linter errors. * First pass at serialization. * Better errors and serialization. * Fix saving output. * Fix saving options. * Fix linter errors and incorrect removal. * Add FUZZ environment variable. * Fix location undefined problem when saving. * Read the actual options file in since we don't have a true copy of the original options. * Fix also compacting start and end outside of loc. * Fix linter error. * Address a few style issues. * Use environment variable for TEST_FUZZ, and disable fuzz testing for Node 6, 8, and 10. * Address more change requests. * Fix lint error. * Move logic into FixtureError base class and add comments. * Throw early if we are in CI, and make sure runFixtureText has its JSDocs comments. * Fix JSDocs. * Change fuzz testing to be opt-in while we only do line changes. * Don't check if file exists before deleting it, and only overwite options if there's a throw property. * Put a newline at the end of JSON files. * Only refrain from throwing if the error is ENOENT. Also, clean up the error message when there is no cause. * Fix linter error.
