This repository is a mono repository which contains multiple page-object base projects
The original idea of a PageObject dates back (as far as I know) to Martin Fowler 2013.
In short a PageObject should be a non HTML based functional API to the web application.
It is recommended to use one PageObject per component and page. That way you will gain maximum reuseability and encapsulation.
Examples for functions in PageObjects would be clickContinue(), selectPassenger(), getPageTitle(), getAge()
A function in a PageObject should NEVER return HTMLElements. Instead return string, number, boolean, objects or arrays (i know arrays are typeof objects in JS).
And if your component or page is containing sub-components you should definetly write a own PageObject for the sub component and let the parent return it.
The ts-page-object and ngx-page-object are providing you with utility functions to quickly write nice PageObjects.
| Function | Description |
|---|---|
| constructor | creates the PageObject by the HTMLElement and when wanted with the selector |
| $ | first HTMLElement for selector |
| $$ | all HTMLElements for selector as array |
| normalizeText | Replaces all whitespace characters with a space. Remove multiple consequtive spaces. Strips |
| textContent | textContent of first HTMLElement
|
| normalizedTextContent | normalized textContent of first HTMLElement
|
| textContents | array of textContent of all HTMLElements |
| normalizedTextContents | array or normalized textContent of all HTMLElements |
| isDisplayed |
true when HTMLElement is in DOM |
| idDisabled |
true when HTMLElement has disabled attribute
|
| waitToAppear | Resolves Promise when HTMLElement is in DOM. Waits 3 seconds per default before rejecting. |
| waitToDisappear | Resolved Promise when HTMLElement is not in DOM. Waits 3 seconds per default before rejecting |
| getFloat | textContent as float number |
| getInt | textContent as int number |
| blur | send blur, input and change event to HTMLElement
|
| setValue | sets value attribute of HTMLInputElement
|
| getValue | get value of value attribute of HTMLInputElement
|
| click | clicks HTMLElement
|
| isChecked |
true when HTMLInputElement has checked attribute
|
| isValid |
true when attribute aria-invalid is not existing |
| keyUp | send keyup event with given key to HTMLInputElement |
Simply create a class which extends PageObject and implement the getSelector function that it returns the HTMLElements selector.
