Turns out lots of people write invalid HTML all the time and no one, including your browser or React, cares. Most invalid HTML combinations don't cause magic reparented nodes; only some do. The HTML5 parsing spec (https://html.spec.whatwg.org/multipage/syntax.html) specifies which tag combinations cause strange parsing behavior. I did my best to encode the logic here. It's more lenient than before in some cases, but more strict in others (before we didn't look at the whole stack of tags; now we warn with deeply nested `p` or `form` or `a` tags).
This is an anti-pattern that can be easily avoided by putting the logic
in componentDidMount and componentDidUpdate instead.
It creates a dependency on stale data inside render without enforcing
a two-pass render.
This triggers a warning if you try to pass a keyed object as a child.
You now have to wrap it in React.addons.createFragment(object) which
creates a proxy (in dev) which warns if it is accessed. The purpose of
this is to make these into opaque objects so that nobody relies on its
data structure.
After that we can turn it into a different data structure such as a
ReactFragment node or an iterable of flattened ReactElements.
This essentially copies all classic element creation tests to the modern
JSX tests. The classic tests doesn't use JSX and modern tests do.
The idea is that the JSX tests can start dropping dynamic checks once
we have Flow support for those features. JSX won't be necessary for
dropping dynamic checks. Plain object will also work. Flow will also not
be necessary for JSX. However, the tests should test for the suggested
combination (JSX + Flow).
This also moves some misplaced tests to ReactDOM and Validator.
Note that the modern tests uses ES6 classes. I will add separate tests for
those. However, these are not guaranteed to have .displayName so all our
error messages should check .name if available instead. This should be
better abstracted but I just adhoc fix this for now.
...unless they already have a wrapper. Also, add tagName to every wrapper.
This ensures that refs are consistent. They always look like composite
components. This effectively hides the internal implementation details of
real DOM components since you can no longer get a ref to one.
In the future we might want to drop this wrapper and have refs refer
directly to the DOM node.
I currently use a hacky way of auto-wrapping inside of ReactNativeComponent
so that any given string can be wrapped. Better suggestions are welcome.
Classes are now pure classes without a legacy factory around them.
Since classes will become just any function that returns a valid instance,
let's drop isValidClass.
There's some hacks in here for auto-mocking frameworks (jest) that mock the
prototype of these classes. These hacks allow these classes to be mounted.
React.DOM is becoming helper factories to generate ReactElements. They're not
classes. It will be ok to call them directly as functions, but not to use them
where a class is expected.
Replace plain function calls to legacy factories with createFactory or
createElement. For ReactDOMComponents the type should be replaced with
strings.
Because we don't have easy access to ReactLegacyDescriptor from within
React, we need to use the .type property to extract the real class.
This will go away later and is covered by unit tests.
Most of the time this is what you want to do, so I've renamed what was Simulate to be SimulateNative.
Now Simulate.change does what you expect, so this fixes#517 and fixes#519.

Not going to check in a script to do this since it will just change every year.
Closes#1006
Two improvements: make sure we set `done = true` when an error message is
received, so that the test output contains the error message instead of
eventually timing out and displaying nothing useful; and increase the
timeout for this particular test from 5000ms (the default) to 20000ms.
