I noticed that `enableSuspenseLayoutEffectSemantics` is not fully implemented in persistent mode. I believe this was an oversight because we don't have a CI job that runs tests in persistent mode and with experimental flags enabled. This adds additional test configurations to the CI job so we don't miss stuff like this again. It doesn't fix the failing tests — I'll address that separately.

// These flags can be in a @gate pragma to declare that a test depends on
|
|
// certain conditions. They're like GKs.
|
|
//
|
|
// Examples:
|
|
// // @gate enableSomeAPI
|
|
// test('uses an unstable API', () => {/*...*/})
|
|
//
|
|
// // @gate __DEV__
|
|
// test('only passes in development', () => {/*...*/})
|
|
//
|
|
// Most flags are defined in ReactFeatureFlags. If it's defined there, you don't
|
|
// have to do anything extra here.
|
|
//
|
|
// There are also flags based on the environment, like __DEV__. Feel free to
|
|
// add new flags and aliases below.
|
|
//
|
|
// You can also combine flags using multiple gates:
|
|
//
|
|
// // @gate enableSomeAPI
|
|
// // @gate __DEV__
|
|
// test('both conditions must pass', () => {/*...*/})
|
|
//
|
|
// Or using logical operators
|
|
// // @gate enableSomeAPI && __DEV__
|
|
// test('both conditions must pass', () => {/*...*/})
|
|
//
|
|
// Negation also works:
|
|
// // @gate !deprecateLegacyContext
|
|
// test('uses a deprecated feature', () => {/*...*/})
|
|
|
|
// These flags are based on the environment and don't change for the entire
|
|
// test run.
