Headless Miracles: Chromedriver Headless VS Chromdriver

Image
You may have heard that we are running the cases in the headless mode so that we could accelerate the execution of the test cases.  So is this true all the time? In this post, I have a little test to compare the headless mode in Chromedriver with version 2.33 and Chromedriver. The tests were run in Windows.
I am using Capybara, I have around 200 test cases written in Cucumber. Tests are running parallel with 15 execution lines. This execution is controlled by tags so we can get the execution time when a tag finished. With this way, we can compare the tag specific time differences and the total time difference. I am using the following Chromedriver instances written in env.rb file in the project.

Mobile Test Automation: Calabash on Xamarin Test-Cloud

Image
If you are testing your application against emulator / simulator, you will still have risks that the expected features may possible not work on several real devices. To handle the real device testing you should have many devices to run your tests. In the current market, we have lots of possibilities for device and operating system versions combinations. Best approach to find most used devices, you should use some statistical data. Most of the cases Pareto analysis can help for selecting high coverage devices. However if you want to find more bug before release, you can focus on the newest device with latest OS version and the oldest devices with the oldest OS version. Any case you should have at least 5-10 android devices and 3-5 iOS devices for a good level of coverage in the beginning. Therefore managing the devices is another problem if you want to have your own local test suites. As a good alternative you can use the cloud services. In this post I want to share some information ab…

Why "Test Risk"

Image
Recently I have had lots of interviews for QA Analyst roles in the company. We called engineers from the level of beginner to senior test engineers for these roles. One of the most important questions in our interview is for understanding why we are testing. Actually this question is more about the philosophy of the testing, as we think the philosophy is generally not liked by people, but everyone who does something about a subject everyday from 9 to 6 should think about why he does this job. I wonder whether the testing job is just only to feed himself or he has some other passion about his profession. That's why this question is very important for me. One of the training given by Ståle Amland which is "Exploratory Testing – Risk-Based Agile Testing", he explains the philosophy of testing as epistemology of testing and he is saying that "all good testers should  practice Epistemology", see these slides in his training:
What is epistemology is according to Amlan…

Create Alias for Interactive Console for Capybara on Windows

Image
If you are working on shell most of the time Aliases are very help full and time saving. For testing purposes you can use Alias for getting ready your test suites. In this post, I want to explain both running Selenium and Capybara on console and creating aliases for each. This post is for Windows machines, if you are using Unix-like see this post.

Creating Scripts for Selenium and CapybaraFirst of all, it is assumed that you have installed Selenium and Capybara correctly and they work on your machines. If you haven't installed, you can see my previous posts. I am using Capybara with Ruby. You can use several different language for Selenium but Capybara works only with Ruby. Create scripts in a directory called scripts (better to use this all user so the path should look like c:/scripts) for your automation tool as following, save them as capybara.rb and sel.py respectively:

First Checks for Mobile Application Testing

Image
Mobile application testing world is differentiated from web application testing in terms of the power of the control. The definition control, how much things you can do when users install the application to their mobile devices. Think, if you store warnings in code and deliver them inside the application code, you can not manage it unless the users update the application.
For sustainable mobile application development, you should have the control of the applications as much as you can do. Therefore the architectural design of the application should be ready for this flexibility. In this post I want to share the most important and primary checks for mobile application testing.
Security First Whatever you develop, you can not disregard the security of the users. If you have an open deep-link for critical information, it will one day be distinguished by some one. Critical actions, such as login, sign-up, credit card submit, should not be sent over get requests, they should be sent over

SQLCMD: Alternative Way of Working with Microsoft SQL Database for Ruby

Image
If you have Microsoft SQL server in your test environment and want to populate test data in Capybara, Calabash scripts you will most probably have difficult time to installing appropriate Ruby gems. One of most popular ruby gem for Mssql connection is tiny_tds but I was not able to install it for both Windows and Unix like environment just because of dependencies. I got the following errors: Errno::EACCES: Permission denied @ rb_sysopen - /Users/mesutgunes/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/tiny_tds-1.1.0/.codeclimate.yml An error occurred while installing tiny_tds (1.1.0), and Bundler cannot continue. Make sure that `gem install tiny_tds -v '1.1.0'` succeeds before bundling. Another popular ruby gem is sequel. It does not give an error for installation but when it comes to usage, it gives the following error for not found adapter. Main problem with the Mssql in unix is finding compatible adapter. See the log:
