示例1: it

  it('file replacements work with forked type checker on watch mode', async () => {
    host.writeMultipleFiles({
      'src/file-replaced.ts': 'export var obj = { one: 1, two: 2 };',
      'src/file.ts': `export var obj = { one: 1 };`,
      'src/main.ts': `
        import { obj } from './file';
        console.log(obj.two);
      `,
    });

    const overrides = {
      fileReplacements: [{
        replace: normalize('/src/file.ts'),
        with: normalize('/src/file-replaced.ts'),
      }],
      watch: true,
    };

    const unexpectedError = `Property 'two' does not exist on type '{ one: number; }'`;
    const expectedError = `Property 'prop' does not exist on type '{}'`;
    const logger = new TestLogger('rebuild-type-errors');

    // Race between a timeout and the expected log entry.
    const stop$ = race<null | string>(
      of(null).pipe(delay(45000 * 2 / 3)),
      logger.pipe(
        filter(entry => entry.message.includes(expectedError)),
        map(entry => entry.message),
        take(1),
      ),
    );

    let errorAdded = false;
    const run = await architect.scheduleTarget(target, overrides, { logger });
    run.output.pipe(
      tap((buildEvent) => expect(buildEvent.success).toBe(true, 'build should succeed')),
      tap(() => {
        // Introduce a known type error to detect in the logger filter.
        if (!errorAdded) {
          host.appendToFile('src/main.ts', 'console.log({}.prop);');
          errorAdded = true;

      takeUntil(stop$),
    ).subscribe();

    const res = await stop$.toPromise();
    expect(res).not.toBe(null, 'Test timed out.');
    expect(res).not.toContain(unexpectedError);
    await run.stop();
  });
