TLDR; Getting started with programming is the hardest part. Installing the IDE, adding dependencies, writing your first test. Pick whichever language you have someone to help you with, or you have a tutorial to work through. Switching languages when you know one is not too hard so do not worry about being stuck with a language, focus on getting started.
TLDR; Downloading a file with RestAssured is as simple as taking the body of a request as a byte array and writing it to a file.
When automating I often have to download files. One very common FAQ for WebDriver is “How do I download a file with WebDriver?".
TLDR; Using Visual SVN, svnserve and local SVN repositories I was able to easily convert SVN to Git on Windows.
I hit every error possible when converting SVN to GIT. I eventually figured out the simplest way to avoid errors during the conversion process.
TLDR; Bonobo is a free and simple to install Git Server for windows.
The Bonobo git server install page instructions don’t fully match the process I had to use to install, so I’ve documented the process here.
TLDR; Coding Tips for beginners.Write your code as temporary comments, remove syntax errors as soon as you see them.
Here are a few tips I’ve been verbally passing on when teaching people on my Java For Testers face to face training.
TLDR; Rather than migration your assertions line by line, create an abstraction class to represent the new implementation and then perform inline refactoring.
I’m experimenting with migrating my projects to JUnit 5.
Many of the “how to migrate to JUnit 5” blog posts show differences, but not a lot of strategies. I used a Branch By Abstraction strategy to migrate JUnit 4 Assertions. This allowed me to experiment with using JUnit5 assertions or AssertJ assertions.
TLDR; Apply MVP principles when coding. Code to the API first. The API is internal before it is external. Unit tests with classes. In code testing with classes in combination. In code API testing. External HTTP API Testing. And then if necessary -In memory and process HTTP API testing. GUI.
A long time ago, in a town which I no longer live in, I wrote a tool called Compendium-TA
Commercially that was a disaster: it was self funded, it took a long time to write and I made some poor technology decisions.
I learned MVP and API First Thinking the hard way. I’ll try and explain within.
