Installation

To install js-automation-tools and save it to your package.json just run:

npm install js-automation-tools --save-dev

Generate timestamp or random digits

There ususally is a need to generate random names. Timestamp can be used to generate a unique string of 13+ digits:

const { stamp } = require('js-automation-tools');

const randomDigits = stamp.getTimestamp(); // '1588556993141'
const newTestName = `My new test ${randomDigits}`; // 'My new test 1588556993141'

It will also write generated digits to a global environment variable process.env.TIMESTAMP that can be easily accessed in any place of your tests:

console.log(process.env.TIMESTAMP); // '1588556993141'

To get new timestamp:

const newRandomDigits = stamp.resetTimestamp(); // '1588558255810'

console.log(process.env.TIMESTAMP); // '1588558255810'

Generate current date and time

Sometimes you need to generate current date and time. It can easily be done with generateDateTime function:

const { dateTime } = require('js-automation-tools');

const currentDateTime = dateTime.generateDateTime(); // '2024-09-23T19:26:35'

Also you can use generateDateTimePlus function that generates current (if no initial date is provided) date and time plus number of days, hours, minutes, seconds if they are provided. This function accepts configuration object with 5 arguments:

1. days - number of days that will be added to current (if no initial date is provided) date and time (optional, default value: 0).
2. hours - number of hours that will be added to current (if no initial date is provided) date and time (optional, default value: 0).
3. minutes - number of minutes that will be added to current (if no initial date is provided) date and time (optional, default value: 0).
4. seconds - number of seconds that will be added to current (if no initial date is provided) date and time (optional, default value: 0).
5. initialDate - string with initial date and time that you want to add a number of days, hours, minutes, seconds to (for example: '2024-03-14T00:14:25', optional, default value: current date and time).

const { dateTime } = require('js-automation-tools');

const currentDateTimePlusDay = dateTime.generateDateTimePlus({ days: 1 }); // '2024-09-24T19:26:35'
const currentDateTimePlusHour = dateTime.generateDateTimePlus({ hours: 1 }); // '2024-09-23T20:26:35'
const currentDateTimePlusMinute = dateTime.generateDateTimePlus({ minutes: 1 }); // '2024-09-23T19:27:35'
const currentDateTimePlusSecond = dateTime.generateDateTimePlus({ seconds: 1 }); // '2024-09-23T19:26:36'

const currentDateTimeMinusHour = dateTime.generateDateTimePlus({ hours: -1 }); // '2024-09-23T18:26:35'

const pastDateTimePlusDay = dateTime.generateDateTimePlus({ days: 1, initialDate: '2024-03-14T00:14:25' }); // '2024-03-15T00:14:25'
const pastDateTimePlusHour = dateTime.generateDateTimePlus({ hours: 1, initialDate: '2024-03-14T00:14:25' }); // '2024-03-14T01:14:25'
const pastDateTimePlusMinute = dateTime.generateDateTimePlus({ minutes: 1, initialDate: '2024-03-14T00:14:25' }); // '2024-03-14T00:15:25'
const pastDateTimePlusSecond = dateTime.generateDateTimePlus({ seconds: 1, initialDate: '2024-03-14T00:14:25' }); // '2024-03-14T00:14:26'

const pastDateTimePlusDayHourMinuteSecond = dateTime.generateDateTimePlus({
    days: 1,
    hours: 1,
    minutes: 1,
    seconds: 1,
    initialDate: '2024-03-14T00:14:25'
}); // '2024-03-15T01:15:26'

It will also write generated date and time to a global environment variable process.env.DATETIME and process.env.NEW_DATETIME that can be easily accessed in any place of your tests.

Send GET, POST or any other requests

Send request to any URL and get response - sendRequest function accepts configuration object with 5 arguments:

1. method - string (for example: 'GET' or 'POST' or 'DELETE' or any other).
2. requestUrl - string with URL of endpoint to send request to (for example: 'https://www.google.com/').
3. headersString - string that contains request headers (for example: '{ "Content-Type": "application/json", "Authorization": "Bearer aBcD1234" }', optional).
4. bodyString - string that contains request body (for example: '{ "test1": 1, "test2": 2 }', optional).
5. logLevel - number (for example: 0 or 1 or 2, optional, default value: 0 - no logs).

Also you can just call sendRequest function without headersString, bodyString, logLevel arguments if they are not needed - for example in GET request:

const { sendRequest } = require('js-automation-tools');

const responseGet = await sendRequest({
    method: 'GET',
    requestUrl: 'https://www.google.com/'
});

const responsePost = await sendRequest({
    method: 'POST',
    requestUrl: 'http://httpbin.org/post',
    headersString: '{ "Content-Type": "application/json", "Authorization": "Bearer aBcD1234" }',
    bodyString: '{ "test1": 1, "test2": 2 }',
    logLevel: 1
});

By default logs are disabled (logLevel set to 0). You can set logging output to one of 3 levels:

• 0 - logs disabled (by default)
• 1 - partial logs are enabled - prints out:
  • Response status code
  • Response body
• 2 - full logs are enabled - prints out:
  • Response status code
  • Response headers
  • Response body

Retry executing function

Retry executing a provided function once per a provided amount of milliseconds until this function will return a value that upon passing a functionCheck check will be true or the amount of provided attempts will be exceeded - retryIfFalse function accepts configuration object with 5 arguments:

1. functionToExecute - function to execute. For example an API request:

   async function () {
       const response = await sendRequest({ method: 'GET', requestUrl: 'https://www.google.com/' });
       return response.body;
   }

2. functionCheck - function to execute to check the result of functionToExecute (if successful - should return true, for example: (responseBody) => responseBody.length > 0, optional).
3. attempts - number of attempts to retry (optional, default value: 10).
4. waitTime - time to wait between retries in milliseconds (optional, default value: 1000).
5. logLevel - number (for example: 0 or 1 or 2, optional, default value: 0 - no logs).

Note: you have to specify the retryIfFalse arguments inside the configuration object as key: value pairs:

const { retryIfFalse, sendRequest } = require('js-automation-tools');

const myFunction = async function () {
    const response = await sendRequest({ method: 'GET', requestUrl: 'https://www.google.com/' });
    return response;
};

const result = await retryIfFalse({
    functionToExecute: myFunction,
    attempts: 10,
    waitTime: 3000,
    logLevel: 2
}); // myFunction will be executed every 3 seconds up to 10 times until its result will be truthy
console.log('result:', result); // result: { statusCode: 200, headers: { 'content-type': 'application/json' }, body: 'Some data' }

OR if you want to provide a custom functionCheck function to check that the result of functionToExecute (or any of its properties) is truthy:

const { retryIfFalse, sendRequest } = require('js-automation-tools');

const myFunction = async function () {
    const response = await sendRequest({ method: 'GET', requestUrl: 'https://www.google.com/' });
    return response;
};
const checkFunction = function (result) {
    return result.statusCode === 200;
};

const result = await retryIfFalse({
    functionToExecute: myFunction,
    functionCheck: checkFunction,
    attempts: 20,
    waitTime: 5000,
    logLevel: 2
}); // myFunction will be executed every 5 seconds up to 20 times until its result statusCode will be 200
console.log('result:', result); // result: { statusCode: 200, headers: { 'content-type': 'application/json' }, body: 'Some data' }

By default logs are disabled (logLevel set to 0). You can set logging output to one of 3 levels:

• 0 - logs disabled (by default)
• 1 - partial logs are enabled - prints out:
  • Each attempt number
• 2 - full logs are enabled - prints out:
  • Each attempt number
  • Response from functionToExecute after each attempt

Read directories

Read the array of directories and get the array of files from this directories:

const { readDirectories } = require('js-automation-tools');

const pathToDirectory1 = path.join(__dirname, 'directory1');
const pathToDirectory2 = path.join(__dirname, '..', '..', 'directory2');

const allFiles = await readDirectories([pathToDirectory1, pathToDirectory2]);
