The constructor with a string argument isn't implemented yet, but
this implements the other variants.
The timestamp constructor doens't handle negative timestamps correctly.
Out-of-bound and invalid arguments aren't handled correctly.
The optional 2nd and 3rd arguments are not yet implemented.
This assumes that `this` is the Array constructor and doesn't yet
implement the more general behavior in the ES6 spec that allows
transferring this method to other constructors.
With this, typing `"\xff"` into Browser's console no longer
makes the app crash.
While here, also make the \u handler call append_codepoint()
instead of calling an overload where it's not immediately clear
which overload is getting called. This has no behavior change.
It's broken for strings with characters outside 7-bit ASCII, but
it's broken in the same way as several existing functions (e.g.
charAt()), so that's probably ok for now.
Finally use Symbol.iterator protocol in language features :) currently
only used in for-of loops and spread expressions, but will have more
uses later (Maps, Sets, Array.from, etc).
With the addition of symbol keys, work can now be done on starting to
implement the well-known symbol functionality. The most important of
these well-known symbols is by far Symbol.iterator.
This patch adds IteratorPrototype, as well as ArrayIterator and
ArrayIteratorPrototype. In the future, sometime after StringIterator has
also been added, this will allow us to use Symbol.iterator directly in
for..of loops, enabling the use of custom iterator objects. Also makes
adding iterator support to native objects much easier (as will have to
be done for Map and Set, when they get added).
Skipped tests count as a "pass" rather than a "fail" (i.e. a test suite
with a skipped test will pass), however it does display a message when
the test is printing.
This is intended for tests which _should_ work, but currently do not.
This should be preferred over "// FIXME" notes if possible.
This commit also exposes JSONObject's implementation of stringify to the
public, so that it can be used by test-js without having to go through
the interpreter's environment.
This moves most of the work from run-tests.sh to test-js.cpp. This way,
we have a lot more control over how the test suite runs, as well as how
it outputs. This should result in some cool functionality!
This commit also refactors test-common.js to mimic the jest library.
This should allow tests to be much more expressive :)
- Use emojis instead of the pass/fail text
- Fix the new version of the script to run inside Serenity
- Don't print erroneous output after 'Output:'; start on a newline
instead
- Skip 'run-tests.sh' while testing
literal methods; add EnvrionmentRecord fields and methods to
LexicalEnvironment
Adding EnvrionmentRecord's fields and methods lets us throw an exception
when |this| is not initialized, which occurs when the super constructor
in a derived class has not yet been called, or when |this| has already
been initialized (the super constructor was already called).
Previously, debugging a test with console.log statements was impossible,
because it would just cause the test to fail with no additional output.
Now, if the output of a test is not "PASS", the output will be printed
under the line where the test failed.
Empty output will have a special message attached to it -- useful when
a test author has forgotten to include `console.log("PASS")` at the end
of a test.
