示例1: createServer
function createServer() {
if (config.https) {
const certs: any = {};
Object.keys(config.https).forEach(k => {
certs[k] = fs.readFileSync(config.https[k]);
});
certs['allowHTTP1'] = true;
return http2.createSecureServer(certs, app.callback());
} else {
return http.createServer(app.callback());
}
}示例2: it
it('should gracefully fail if provided a non-error', async done => {
expect.assertions(2);
const app = new Koa();
class InvalidError {}
// Add middlewares
app.use(errorHandler());
app.use(() => {

});
const response = await request(app.callback()).get('/');
// Assertions
expect(response.status).toBe(500);
expect(response.body).toEqual({
error: {
additionalDevelopmentData: {
stack: expect.stringContaining('Error: Cannot handle non-errors as errors'),
},
code: '',
error: 'Internal Server Error',
message: 'An internal server error occurred',

},
});
// Done

});示例3: it
it('should log latency in milliseconds', async done => {
expect.assertions(3);
const app = new Koa();

connectDB().then(() => {
console.log('database connected')
app.use(router.routes())
http.createServer(app.callback()).listen(4000, () => {
console.log(`http server listening on port: 4000`)

expect.assertions(2);
const app = new Koa();
const data = {
