示例1: TestWatcher
const startRun = (
globalConfig: Config.GlobalConfig,
): Promise<void | null> => {
if (isRunning) {
return Promise.resolve(null);
}
testWatcher = new TestWatcher({isWatchMode: true});
isInteractive && outputStream.write(specialChars.CLEAR);
preRunMessagePrint(outputStream);
isRunning = true;
const configs = contexts.map(context => context.config);
const changedFilesPromise = getChangedFilesPromise(globalConfig, configs);
return runJest({
changedFilesPromise,
contexts,
failedTestsCache,
filter,
globalConfig,
jestHooks: hooks.getEmitter(),
onComplete: results => {
isRunning = false;
hooks.getEmitter().onTestRunComplete(results);
// Create a new testWatcher instance so that re-runs won't be blocked.
// The old instance that was passed to Jest will still be interrupted
// and prevent test runs from the previous run.
testWatcher = new TestWatcher({isWatchMode: true});
// Do not show any Watch Usage related stuff when running in a
// non-interactive environment
if (isInteractive) {
if (shouldDisplayWatchUsage) {
outputStream.write(usage(globalConfig, watchPlugins));
shouldDisplayWatchUsage = false; // hide Watch Usage after first run
isWatchUsageDisplayed = true;
} else {
outputStream.write(showToggleUsagePrompt());
shouldDisplayWatchUsage = false;
isWatchUsageDisplayed = false;
}
} else {
outputStream.write('\n');
}
failedTestsCache.setTestResults(results.testResults);
},
outputStream,
startRun,
testWatcher,
}).catch(error =>
// Errors thrown inside `runJest`, e.g. by resolvers, are caught here for
// continuous watch mode execution. We need to reprint them to the
// terminal and give just a little bit of extra space so they fit below
// `preRunMessagePrint` message nicely.
console.error(
'\n\n' +
formatExecError(error, contexts[0].config, {noStackTrace: false}),
),
);

const emitFileChange = () => {
if (hooks.isUsed('onFileChange')) {
const projects = searchSources.map(({context, searchSource}) => ({

testPaths: searchSource.findMatchingTests('').tests.map(t => t.path),
