[tests] add
assertConsole<method>Dev
helpers (#28732)
## Overview **Internal React repo tests only** Depends on #28710 Adds three new assertions: - `assertConsoleLogDev` - `assertConsoleWarnDev` - `assertConsoleErrorDev` These will replace this pattern: ```js await expect(async () => { await expect(async () => { await act(() => { root.render(<Fail />) }); }).toThrow(); }).toWarnDev('Warning'); ``` With this: ```js await expect(async () => { await act(() => { root.render(<Fail />) }); }).toThrow(); assertConsoleWarnDev('Warning'); ``` It works similar to our other `assertLog` matchers which clear the log and assert on it, failing the tests if the log is not asserted before the test ends. ## Diffs There are a few improvements I also added including better log diffs and more logging. When there's a failure, the output will look something like: <img width="655" alt="Screenshot 2024-04-03 at 11 50 08 AM" src="https://github.com/facebook/react/assets/2440089/0c4bf1b2-5f63-4204-8af3-09e0c2d752ad"> Check out the test suite for snapshots of all the failures we may log.
