# Agenda
* Why Galen?
* Responsive Testing
* Galen Specs
* Demo
* Best Practices and Lessons Learned
* Outlook
---
# Why Galen
* Different screen size and element appearance for devices<!-- .element: class="fragment"-->
* Responsive Layout drives testing effort<!-- .element: class="fragment"-->
* Agile development need repeatable automated tests<!-- .element: class="fragment"-->
>NOTES:
* Browser-Wanking
* Combinations of screen size and browser increase efforts
* 20 pages in 4 browser
* muliplied with 4 device classes
* Repeats in every sprint
* human are not good in repeating the same things over and over again
--
# About Galen
> "Galen is a OSS tool for testing html layout in a real browser"
* Galen is a OSS tool for testing html layout in a real browser
* Tests describing the expected behaviour in a certian device
* Features<!-- .element: class="fragment"-->
* Human readable DSL<!-- .element: class="fragment"-->
* uses Selenium as Runtime (e.g page interaction with Selenium possible)<!-- .element: class="fragment"-->
* Advanced test suite syntax with data-providers<!-- .element: class="fragment"-->
* Advanced Reporting<!-- .element: class="fragment"-->
>NOTES:
* interaction with WebDriver possible
* positive AND negative feedback
--
# Architecture
* Test specifications and device informations = Test Run
* Tests are running in Selenium
* API for Java and JavaScript<!-- .element: class="fragment"-->
>NOTES:
* Galen is written in Java
* Rhino as API to JavaScript
--
* Layout Testing is challenging
* Simple solution: test object relative to each other via a special syntax and rules
--
* Runs in Selenium Grid
* Test several browser, e.g in a cloud like Sauce Labs or BrowserStack
* Supports testing on different mobile devices
* run multiple tests in parallel to save time
>NOTES:
* can be used with Appium for mobile devices
--
# Installation
* Manual Install
* NPM Install
<br>
```bash
(sudo) npm install -g galenframework-cli
```
---
# Size does matter ...
* responsive Tests in TDD-Style possible
* requirements are written in Layout Spec
* verify requirments via a test run
* screen size import during execution and for the the assumed layout
---
# Galen Spec Language
* elements are defined
* devices are matched via Tags
* rules describe your expectations
--
# Example
```python
@objects
content #content
heading .tile_head_line_icon
= Content should not exceed screen width =
content:
width 90 to 100% of viewport/width
= Content should not exceed component width =
@on mobile
content.heading:
inside parent ~0px left
@on desktop
content.heading:
inside parent ~5px left
```
* Without tag every variant is used
--
## Reuse
* Import
* Components
--
## Import of general specs
```python
@objects
tile-image-* .tile_inline_first
tile-text-* .tile_inline_second
@import shared/commonLayout.gspec
= Content should not exceed screen width =
tile-image-*:
aligned horizontally all tile-image-1
```
--
## Components
* behave like widgets, z.B. menu or list entries
* Pseudo-element 'parent' for reference
```python
@objects
tile-image-* .tile_inline_first
tile-text-* .tile_inline_second
= Content should not exceed screen width =
tile-image-*:
aligned horizontally all tile-image-1
= Info section =
tile-text-*:
component shared/tileTextComponent.gspec
```
--
## Structure of tests
* Galen allows using parameters:
```python
@@ table devices
| device | size |
| mobile | 500x700 |
| tablet | 900x600 |
| desktop | 1300x700 |
@@ parameterized using devices
homepage on ${device}
${websiteUrl} ${size}
check specs/homepage.spec --include "${device}"
```
Run via commandline
```
galen test my.test -DwebsiteUrl='https://getbootstrap.com' --htmlreport reports/
```
--
# Test execution
Can run single tests:
```python
$ galen check home-page.spec
--url "http://example.com/home"
--size 1024x800
--include desktop
--htmlreport report.html
```
--
# Image comparison
* Pagedump taking screenshots of current page
```python
galen dump "specs/homepage.spec"
--url "http://galenframework.com"
--size "1024x768"
--export "dumps/homepage-dump"
--max-width "200"
--max-height "200"
```
--
# Usage in Spec
```python
header-logo
image: file imgs/header-logo.png, error 4%
```
---
# Report
* Report is helping to show errors
--
# Sample-Report

# Interaction
* [GalenPages API](http://galenframework.com/docs/reference-galenpages-javascript-api/) helps to support simple interactions
* Simple PageObject-Pattern Library
```javascript
var login = arg.login, password = arg.password; // test data
this.LoginPage = $page("Login page", {
email: "input.email", // css locator
password: "xpath: //input[@class='password']", // xpath locator
submitButton: "id: submit", // id locator
load: function () {
this.open("http://example.com/login");
return this.waitForIt();
},
loginAs: function (userName, password) {
this.email.typeText(userName);
this.password.typeText(password);
this.submitButton.click();
}
});// now you can use it like this
new LoginPage(driver).load().loginAs(login, password);
```

# Sum up
* TDD in Responsive Design possible
* decribe layout requirements in layout spec
* implement frontend
* verify frontend design
>NOTES:
Once the html is finished you can define the references to all your objects in spec using one of the locators: id, css, xpath
--
## Best Practices and Lessons Learned
* General
* Responsive testing is possible
* but don't check 'each pixel'
* use element relations
* tests can be flaky
* infrastructure (Integration Tests)
* Use Selenium Grid
* Implement step by step (pages, browser, screen sizes)
* not test all
>NOTES:
* Aufgrund von verschiedenen Browsern Pixel-genau nicht sinvoll (Rundungen ...)
* Integrationstests aufgrund ihrer Natur!!
* Fokus beim Testen wichtig
* Nicht den Fehler machen am Anfang alles zu testen
* Eine Platform/Browser zu Beginn
* Schritt für Schritt ausbauen
