protractor_utilities

protractor utility function provides a upperlevel over the protractor libraries.
So for setting or checking the element you need not use directly use protractor library like element(by.id)
you need to just pass location reference and value to the library method it will be
taken care automatically.
For setting or checking the element just need to provide location in the format of interface ILocRef(.i.e by which the
element can be identified by xpath or id or class and the specifier means id or xpath or class reference)
and value you are interested in.

interface ILocRef {
type: LocationTypes;
value: string;
}

In this above case LocationTypes is enum as specified below

enum LocationTypes{
Id = "id",
Xpath = "xpath",
Class = "class"
}

So the type in ILocRef can be either "id" or "xpath" or "class"
and the value is the corresponding specifier.

So if you want to set the location for username the location will be provided
as

{ type: LocationTypes.Xpath, value: '//*[@id="username"]' }

in this case we are setting the username through the xpath reference.

Say i want to set the username as "abc"

setElement({ type: LocationTypes.Xpath,
value: '//*[@id="username"]' },"abc");

usuage in Typescript:

import {
setElement,
setValues,
checkElement,
checkValues,
elemClick,
waitUntillLoaded,
waitUntillEnabled,
readExcel
} from "protractor_utility";

Interface Type Exported:

import {
ILocRef,
LocationTypes,
IValueTypes } from "protractor_utility";

Enums Exported

Enums Used for specifying the location of the element by which the
element can be identified by xpath or id or class

export enum LocationTypes {
Id = "id",
Xpath = "xpath",
Class = "class"
}

Enums Used in reading from the Excel sheet.Used for
specifying what it needs to read Value or Location or
CheckValue parameters from Excel Sheet

export enum IValueTypes {
Value = "value",
CheckValue = "checkValue",
Location = "location"
}

Interfaces Exported

Defines the format for providing the identification
of the Element

export interface ILocRef {
type: LocationTypes;
value: string;
}

Defines the complete structure for setting the value in the
Element.location defines the parameters for the identification of the
element.value defines the value that need to be set in the Element

export interface IElement {
location: ILocRef;
value: string;
}

Methods Available:

• setElement,
• setValues,
• checkElement
• checkValues
• elemClick
• waitUntillLoaded,
• waitUntillEnabled,
• readExcel

All our examples we will consider setting value for loginPage
which has username,password and submit button

This is how we should have created the interface for the page:

export interface ILoginPage= {
username?: T;
password?: T;
submit?: T;
}

This is how we would have developed the ids and values to be set for the page:

const loginPageIds: ILoginPage = {
username: { type: LocationTypes.Xpath, value: '//*[@id="username"]' },
password: { type: LocationTypes.Id, value: "password" },
submit: { type: LocationTypes.Class, value: "submit" }
};

const loginPageValues: ILoginPage = {
username: "abc",
password: "pass"
};

This will be used for checking values

export const loginPageCheckValues: ILoginPage = {
username: "abc",
password: "pass"
};

setElement

for setting a single element For Example setting username only.

setElement( { type: LocationTypes.Xpath,
value:'//*[@id="username"]' },
"abc");

For setting multiple element at one use setValues

setValues

For setting multiple values in loginPage
Example: for setting multiple values .i.e username and password
as we have only username and password in loginPageValues though we have
id for submit button in loginPageIds.
It will set value only for elements which is present in both.

setValues(loginPageIds,loginPageValues)

checkElement

For checking single value in loginPage. Example: For instance checking the username value set is "abc"

checkElement(
{ type: LocationTypes.Xpath, value: '//*[@id="username"]' },
"abc");

checkValues

For checking multiple values in loginPage:
Example: For instance for checking mulltiple values .i.e. username is set to 'abc'
and password is set to 'pass' as specified in loginPageCheckValues specified above.
Here as well as the loginPageCheckValues have only two values though loginPageIds
also includes submit id , it will check elements which matches both.

checkValues(loginPageIds,loginPageCheckValues)

elemClick

For clicking on the Element

Example: For instance need to click on the submit button.
Here we need to send the location Ref of the submit button(by which it will know
where to click by id or xpath or class) defined as a value to submit in loginPageIds
to the elemClick
method.This can be done by

elemClick(loginPageIds.submit)

waitUntillLoaded

To make protractor wait for the element

Example: For instance to ascertain login page as appeared after loading our page
we can wait till username id has appeared in the screen

waitUntillLoaded(loginPageIds.username)

waitUntillEnabled

To make protractor wait till the element is Enabled

Example: For instance to make protractor wait till Submit button is enabled.
This may happen in the case when Submit button is enabled only after the username
and password is entered.

waitUntillEnabled(loginPageIds.submit)

readExcel

In the above, loginPageIds, loginPageValues and loginPageCheckValues we actually provided.
But these values can also be read from a Excel file by specifying in a prescribed format.
To provide the ids and values from a excel sheet

Example: For giving ids through Excel

export const loginPageIds: ILoginPage = readExcel(
IValueTypes.Location,
"./e2e/values/login.xlsx"
);

First param will be what we trying to retrieve location or Value or CheckValue
defined by the enum IValueTypes.
Second param will be the path of the Excel sheet where we have saved the value.

These conditions need to be followed in excel sheet:

• In this excel sheet providing values
  First sheet need to be the location
  Second sheet need to be providing value
  Third sheet need to be providing checkValues.
  This order needs to be maintained as this is temporarily hardcoded in library.

• Also for location need to be provided under headers PROPERTYKEY,LOCATIONTYPE,LOCATIONVALUE

• For Value and CheckValues need to be provided under headers PROPERTYKEY,PROPERTYVALUE

For giving value through Excel

export const loginPageValues: ILoginPage = readExcel(
IValueTypes.Value,
"./e2e/values/login.xlsx"
);

For giving Check value through Excel

export const loginPageCheckValues = readExcel(
IValueTypes.CheckValue,
"./e2e/values/login.xlsx"
);

Example refer to this Excel for providing values: login.xlsx

For the complete example refer to this folder:

e2e folder

Also use this Angular project for running the protractor test
project

Starting the Angular project

• clone the projectusing git clone ,
• move to the folder Angular_Learning created by clone and do npm install
• ng serve to start the project

Running the protractor test

• update the drivers ans selenium jars using webdriver-manager update
• start the selenium server using webdriver-manager start
• And inside the Angular_Learning folder run the command

  node node_modules/protractor/bin/protractor e2e/protractor_jasmine.conf.js

This should run the protactor test using jasmine and you should be able to see
screenshots under reports. If you make the test fail also you should be also able to see
screenshots in the report.
