As you know, Java Memory Model is not transactional, so we need to get transactional flow somehow.

Karma and Jasmine are one of the most popular combinations which help developers to test front-end code. To run the same test with different data input (data-driven testing) we can use a loop with it inside, or we can import one of the available library, but today I’ll show you how to make that smartly by own hands.

Today post maybe is not a too technical one but I was pushed someday to use Ubuntu desktop, and I had to provide some visual adjustments there.

Did you ever spend a few hours for extracting needed layers from a .psd file? That would be an annoying thing to do, wouldn’t be? Today I’ll show you a swift way to slicing Photoshop layers.

Have you worked someday at the project and you are so bored by writing the same kind of tests over and over? Alternatively, maybe you drop some test cases because the implementation of those is too complicated? Today I’ll show you the way to writing tests much faster and with less effort than with JUnit.
