Automation testing core
- 1. Automation testing core Konopelko Petro
- 2. Test automation Test automation is the use of special software (separate from the software being tested) to control the execution of tests and the comparison of actual outcomes with predicted outcomes.
- 3. Automate or not Automate? Test cases to be automated can be selected using the following criterion to increase the automation ROI (Return on Investment) ● High Risk - Business Critical test cases ● Test cases that are executed repeatedly ● Test Cases that are very tedious or difficult to perform manually ● Test Cases which are time consuming The following category of test cases are not suitable for automation: ● Test Cases that are newly designed and not executed manually at least once ● Test Cases for which the requirements are changing frequently
- 4. Test Automation Strategy Based on a Three-Level Model ● Unit testing ● Functional testing ● User interface testing
- 5. Unit testing Unit testing is a software testing method by which individual units of source code are tested to determine whether they are fit for use. At this level automated tests are the component or unit tests designed by developers.
- 6. API - an application programming interface is a set of subroutine definitions, protocols, and tools for building application software.
- 7. Web API A server-side web API is a programmatic interface consisting of one or more publicly exposed endpoints to a defined request–response message system, typically expressed in JSON or XML, which is exposed via the web—most commonly by means of an HTTP-based web server. API testing tools ● SOAP UI (partially free) ● HP QTP(UFT) (paid) ● HttpMaster (paid) ● Parasoft (paid) ● vREST (paid) ● Postman (chrome plugin, free)
- 8. GUI testing Graphical User Interface (GUI) testing is the process of testing the system's GUI of the System Under Test. GUI testing involves checking the screens with the controls like menus, buttons, icons, and all types of bars - toolbar, menu bar, dialog boxes and windows, etc. Web Automation tools ● Selenium (free) ● HP QTP (paid) ● WATIN (free) ● Telerik Test Studio (paid) ● Test Complete Web(paid)
- 9. Selenium Selenium IDE (Builder) Selenium IDE is a Firefox add-on that makes it easy to record and playback tests in Firefox. You can even use it to generate code to run the tests with Selenium Selenium RC (obsolete) Selenium Remote Control is a client/server system that allows you to control web browsers locally or on other computers, using almost any programming language and testing framework. Selenium WebDriver Selenium WebDriver can drive a browser natively either locally or on remote machines. Selenium Grid Selenium Grid takes Selenium Remote Control to another level by running tests on many servers at the same time, cutting down on the time it takes to test multiple browsers or operating systems.
- 10. Selenium WebDriver Pros ● Open source ● Different languages (C#, Java, Ruby, Python, Javascript) ● Big community ● Supports a lot of browsers ● It becomes the standard (W3C Working Draft 29 November 2016)
