Utilities

Logging, waiting, time, random numbers, Base64 and HTTP requests. All three log levels are uploaded to the task log and show up in the console in real time.

기능 개요

·Three log levels — logd / logi / loge; the console shows debug in grey and errors in red
·randomInt / randomFloat / randomChoice add randomness to waits, taps and wording
·httpGet / httpPost never throw on failure and always return { ok, status, text, json, headers, error }

logd#

A debug log line: the details you look at while troubleshooting. It is uploaded too and shows in grey in the log panel.

typescript

logd(message: any): void;

매개변수

이름	타입	필수	기본값	설명
`message`	`any`	예	—	What to log. Objects are serialised to JSON; anything else is converted to a string.

주의사항

Keep it out of tight loops: the server keeps only the most recent part of each task's log, and noise pushes out what matters.

예제

javascript

logd(client.windowSize());

logi#

An info log line: which step the script reached and what it got.

typescript

logi(message: any): void;

매개변수

이름	타입	필수	기본값	설명
`message`	`any`	예	—	What to log. Objects are serialised to JSON; anything else is converted to a string.

예제

javascript

logi('step 1 done');

loge#

An error log line for failures. It is highlighted in red in the log panel.

typescript

loge(message: any): void;

매개변수

이름	타입	필수	기본값	설명
`message`	`any`	예	—	What to log. Objects are serialised to JSON; anything else is converted to a string.

예제

javascript

loge('the login button never appeared');

setClickLog#

Turn click logging on or off. clickElement / clickImage / clickText record taps and misses in the task log by default; turn it off in busy loops so the log stays readable.

typescript

setClickLog(on: boolean): boolean;

매개변수

이름	타입	필수	기본값	설명
`on`	`boolean`	예	—	true to log, false to stay quiet.

반환값

타입	설명
`boolean`	The previous setting.

주의사항

Only these three functions are affected. Coordinate taps such as client.click never log.

예제

javascript

setClickLog(false);
for (var i = 0; i < 50; i++) {
  clickElement('label', 'Next', 1);
}
setClickLog(true);

sleep#

Wait for the given number of seconds. Returns immediately when the task is stopped.

typescript

sleep(seconds: number): void;

매개변수

이름	타입	필수	기본값	설명
`seconds`	`number`	예	—	How many seconds to wait; fractions are allowed.

예제

javascript

sleep(1.5);

getNowTimestamp#

The current Unix timestamp in seconds (an integer).

typescript

getNowTimestamp(): number;

반환값

타입	설명
`number`	The number of seconds since 1970-01-01 00:00:00 UTC.

주의사항

To measure elapsed time, store the timestamp at the start and subtract it later to get the seconds that passed. For milliseconds use Date.now().

예제

javascript

var start = getNowTimestamp();
sleep(2);
logi(getNowTimestamp() - start);

getNowTime#

The current time as 2026-10-01 14:05:09, in the device's local time zone.

typescript

getNowTime(): string;

반환값

타입	설명
`string`	"YYYY-MM-DD HH:MM:SS", with month, day, hour, minute and second zero-padded to two digits.

주의사항

For the date only take the first 10 characters: getNowTime().slice(0, 10); for hours and minutes only: getNowTime().slice(11, 16).

예제

javascript

logi('started at ' + getNowTime());

randomInt#

A random integer with both ends included: randomInt(1, 6) is a die roll.

typescript

randomInt(min: number, max: number): number;

매개변수

이름	타입	필수	기본값	설명
`min`	`number`	예	—	The lower bound (inclusive).
`max`	`number`	예	—	The upper bound (inclusive).

반환값

타입	설명
`number`	An integer in [min, max]. Swapped bounds are handled.

예제

javascript

var n = randomInt(1, 6);

관련 항목 randomFloat、randomChoice

randomFloat#

A random decimal with both ends included, kept to 1 decimal place by default: randomFloat(1.5, 3) may give 1.5, 2.3 or 3. For example, pause for a random while between rounds: sleep(randomFloat(1.5, 3)).

typescript

randomFloat(min: number, max: number, digits?: number): number;

매개변수

이름	타입	필수	기본값	설명
`min`	`number`	예	—	The lower bound (inclusive).
`max`	`number`	예	—	The upper bound (inclusive).
`digits`	`number`	아니오	`1`	How many decimal places to keep; an integer from 0 to 10.

반환값

타입	설명
`number`	A decimal in [min, max] with digits decimal places. Swapped bounds are handled.

예외

예외	발생 조건
`WDAError`INVALID_ARGUMENT	digits is not an integer from 0 to 10.

주의사항

When the range is too narrow to hold two different values at that precision, more places are kept automatically: at 1 decimal place randomFloat(0.45, 0.55) could only ever be 0.5, so it returns two-decimal values such as 0.47 or 0.52. The result always stays inside [min, max].
For values that need to be fine-grained, such as screen-ratio coordinates, pass the precision: client.click(randomFloat(0.3, 0.7, 3), randomFloat(0.4, 0.6, 3)). At 1 decimal place the tap could only land on 0.3, 0.4 and so on.

예제

javascript

sleep(randomFloat(1.5, 3));
var x = randomFloat(0.2, 0.8, 3);

관련 항목 randomInt、randomChoice、sleep

randomChoice#

typescript

randomChoice<T>(list: T[]): T | null;

매개변수

이름	타입	필수	기본값	설명

반환값

타입	설명
`T \| null`	The chosen item, or null for an empty array.

예외

예외	발생 조건

예제

javascript

var greeting = randomChoice(['Hello', 'Good morning', 'Hi']);
logi(greeting);

base64Encode#

httpGet#

Send a GET request.

typescript

httpGet(url: string, timeoutSec?: number, headers?: Record<string, string>): HttpResult;

type HttpResult = {
  ok: boolean;
  status: number;
  text: string;
  json: any;
  headers: Record<string, string>;
  error: string;
};

매개변수

이름	타입	필수	기본값	설명
`url`	`string`	예	—	The full address, starting with http:// or https://. Put query parameters in the address; non-ASCII text and spaces are encoded for you.
`timeoutSec`	`number`	아니오	`15`	The longest wait, in seconds.
`headers`	`Record<string, string>`	아니오	—	Request headers, for example { Authorization: 'Bearer xxx' }.

반환값

타입	설명
`HttpResult`	{ ok, status, text, json, headers, error }. ok means a 2xx status; status 0 means no response arrived (no network, timeout, task stopped) and error says why; json holds the parsed body when the response is JSON and null otherwise; header names are lowercase. Failures do not throw — check ok.

예외

예외	발생 조건
`WDAError`INVALID_ARGUMENT	The address does not start with http(s), the wait is not a number or exceeds 600, or the headers are not an object.

예제

javascript

if (r.ok) {
  logi(r.json.items.length);
} else {
  loge(r.status + ' ' + r.error);
}

httpPost#

매개변수

이름	타입	필수	기본값	설명
`url`	`string`	예	—	The full address, starting with http:// or https://. Put query parameters in the address; non-ASCII text and spaces are encoded for you.
`body`	`string \| object`	아니오	—	The request body. A Content-Type header you set yourself is never overridden.
`timeoutSec`	`number`	아니오	`15`	The longest wait, in seconds.
`headers`	`Record<string, string>`	아니오	—	Request headers, for example { Authorization: 'Bearer xxx' }.

반환값

타입	설명
`HttpResult`	{ ok, status, text, json, headers, error }. ok means a 2xx status; status 0 means no response arrived (no network, timeout, task stopped) and error says why; json holds the parsed body when the response is JSON and null otherwise; header names are lowercase. Failures do not throw — check ok.

예외

예외	발생 조건
`WDAError`INVALID_ARGUMENT	The address does not start with http(s), the wait is not a number or exceeds 600, or the headers are not an object.

주의사항

Requests go to whatever address the script names; the script's author is responsible for where that data goes.

예제

javascript

var r = httpPost('https://example.com/report', 'device=' + getDeviceId() + '&status=ok');
if (!r.ok) {
  loge(r.status + ' ' + r.error);
}
