Characteristics of End­2­End Testing

Different types of testing:Regression testsFunctional approval tests

Parallel tests with GUIs are complexStateful tests: user logins, sessions, historySetup and cleanup of test data

Manual effort > effort for test automation

Virtual Machines vs. Container (explained on the example of Docker)

Immutable Filesystem Layers(explained on the example of Docker)

Advantages of Container Technology

Isolation of environmentsRepository for versioning and distributionReproducible application environmentDockerfile, docker­compose.yml

Starting containers on­the­flyOptimized for parallel executionLess memory overheadShared Linux kernel

Containerized GUIs### start the docker container via x­forwarding docker run ­it ­e DISPLAY=$DISPLAY ­v /tmp/.X11­unix:/tmp/.X11­unix:rw rasch/inkscape

### start the docker container with VNC interface # connect via URL: http://localhost:6911/vnc_auto.html?password=vncpassword docker run ­it ­p 5911:5901 ­p 6911:6901 consol/ubuntu­xfce­vnc docker run ­it ­p 5912:5901 ­p 6912:6901 consol/centos­xfce­vnc

Test definition (Java Script)

Test Case Structure// testcase.js

/************************************* * Initialization *************************************/ _dynamicInclude($includeFolder); var testCase = new TestCase(60, 70); var env = new Environment(); var appNotepad = new Application("gedit"); var region = new Region();

/****************************** * Description of the test case ******************************/ try

//...

/************************************************ * Exception handling and shutdown of test case **********************************************/ catch (e) testCase.handleException(e); finally testCase.saveResult();

Call all Sahi Functions// testacase.js /************************ * Call Sahi Functions ***********************/

_navigateTo("http://sahi.example.com/_s_/dyn/Driver_initialized"); _highlight(_link("SSL Manager")); _isVisible(_link("SSL Manager")); _highlight(_link("Logs")) _click(_link("Logs"))

testCase.endOfStep("Test Sahi landing page", 5);

Fluent API for UI Testing// testacase.js

/*** open calculator app ***/ var calculatorApp = new Application("galculator") .open(); testCase.endOfStep("Open Calculator", 3);

/*** calculate 525 + 100 ***/ var calculatorRegion = calculatorApp.getRegion(); calculatorRegion.type("525") .find("plus.png") .click() .type("100") .find("calculate") .click();

testCase.endOfStep("calculate 525 +100", 20);

Custom Functions// e.g. excluded into a separate common.js

/********** * Combine click and highlight *********/function clickHighlight($selector) _highlight($selector); _click($selector);

/*************** * Open PDF in native viewer **************/ var PDF_EDITOR_NAME = "masterpdfeditor3";

function openPdfFile(pdfFileLocation) return new Application(PDF_EDITOR_NAME + ' "' + pdfFileLocation + '"').open();
