示例1: test
test('Finds a free port (no timeout)', function (done) {
this.timeout(1000 * 10); // higher timeout for this test
if (process.env['VSCODE_PID']) {
return done(); // this test fails when run from within VS Code
}
// get an initial freeport >= 7000
ports.findFreePort(7000, 100, 300000).then(initialPort => {
assert.ok(initialPort >= 7000);
// create a server to block this port
const server = net.createServer();
server.listen(initialPort, void 0, void 0, () => {
// once listening, find another free port and assert that the port is different from the opened one
ports.findFreePort(7000, 50, 300000).then(freePort => {
assert.ok(freePort >= 7000 && freePort !== initialPort);
server.close();
