Leszek Swirski 5e2c23e2d3 [destructuring] Get non-coercible message contents in runtime For desrtucturing assignments from null/undefined, we throw an error that references the destructuring object literal's property name, e.g. for var { x } = null; we report that we cannot destructure 'x' from null. Rather than calculating this property during bytecode generation (and including it in the bytecode as an argument to the type error constructor), we can calculate it at exception throwing time, by re-parsing the source in a similar way to the existing call site rendering. This slightly decreases bytecode size and slightly decreases the amount of work the bytecode compiler needs to do. In the future, it could also allow us to give more detailed error messages, as we now have access to the entire AST and are on the slow path anyway.

JavaScript tests with expected output

Tests in test/message pass if the output matches the expected output. Message tests are particularly useful when checking for exact error messages.

Tests and their expected output must have the same filename, with the .js and .out extension.

foo.js
foo.out

All tests must end with an exception. The test runner does not handle output from multiple runs, e.g., --stress-opt. Without an exception, the output will be generated several times and the comparison will fail.

You can use a regex in the expected output instead of the exact path:

*%(basename)s:7: SyntaxError: Detected cycle while resolving name 'a'

Empty lines are ignored in the comparison, but whitespaces are not.

Exact details of the test runner are in testcfg.py.
