A Model of Automating

TLDR; I automate tasks by using tools and writing code. Understand what they abstract to learn more. A Model of Automating What do you automate? I automate tasks. Sometimes I use a tool to automate tasks. Sometimes I write code. But of course my model that underlies that statement doesn’t have as clear a separation as the words suggest. My ‘tool’ and ‘code’ models do not have a clear separation.

Dear Evil Tester: "How can I learn Automation?"

TLDR; Don’t just ‘learn automation’. Learn it for a reason. When I attend conferences and meetups, people often ask me how they can learn to automate stuff. I then have to ask some follow up questions. This is not my normal approach for a “Dear Evil Tester” answer. A “Dear Evil Tester” answer makes assumptions and takes the question and the words in the question at face value. Because that is funnier, and allows me to address generic points.

So I did what all good Selenium debuggers do… I tried in the browser but Chrome didn’t match it. Tempted though I was to blame Chrome, I tried with XPath, and that worked fine: //p[@id='select.me.by.id'] After a bit of web searching, the solution was clear.

TLDR; Some sites issue an X-FRAME-OPTIONS header that stops them loading in an iframe, remove it for responsive web testing with a proxy. Does your favourite responsive testing tool fail to display the site you want to test? Have you blamed the tool and now rely on browser dev tools? Well, here’s a possible solution for you. But before that, let’s look at that situation in more detail: you want to practice your responsive web testing, you have your responsive web testing tool it loads your chosen web site into an iframe your chosen web site doesn’t want to load in an iframe your tool displays a blank image, with no error, instead of the page you curse and go back to the browser dev tools Stop.

How to Debug WebDriver JavascriptExecutor in Java

TLDR; JavascriptExecutor requires us to learn JavaScript and use the Browser Console, and check your locator assumptions using FirePath A common theme when debugging WebDriver code is the need to jump between breakpoints, evaluate and browser dev tools.

How to debug chained WebDriver `findElement` methods in Java

TLDR; split code across lines and breakpoint, and use browser dev tools to test the locators used. Have you ever had an argument about fluent code? Discussions about “train wrecks” and “impossible to debug”? WebDriver has the ability to chain findElement calls, and create such “train wrecks”. How do you debug it if you use it? (There is a summary video at the bottom of this post.) Example: WebElement element = driver.

Click on the side of the screen to create a breakpoint. Run the code in debug and it stops where you want it. But what if you only wanted to stop on that breakpoint sometimes. What do you do?

Selenium WebDriver 3.0.0-beta2 and JUnit and GeckoDriver v 0.10.0

WebDriver Windows 10 Anniversary Build and Edge 14393

TLDR; if your version of Edge is not listed on the WebDriver Edge page, try the insider build. I am experimenting with Selenium WebDriver 3.0.0 beta2 at the moment - more on that later. And this morning I could not get MS Edge to work. I could not understand how the beta was affecting Edge. And then I remembered that I upgraded to Windows 10 Anniversary last night so now Edge is on a new version:
