To create this live template, open the preferences and go to Editor -> Live Templates. The new test root should be marked with the icon in the Project tool window. The code our Live Template should generate will look something like this: Its good practice to have generated tests automatically insert a fail into the generated method any test should fail first even if we havent finished writing it yet. This still seems to be the correct procedure for IntelliJ 14. When we run the test, its this DisplayName that shows in the run window: Not only does this encourage us to be descriptive, since its a text string and not a method name, it supports special characters, which can help readability. I am not sure I understand but I think "drag and drop" package folder/class in project view on the left side of IDE will help :). Select your test folder and the click on the Tests option (this will tell IntelliJ this particular folder is a test folder) and then click Ok.

In our case the cause of the problem should be quite clear since we intentionally put the wrong number in as the "actual" argument. They should be stored in a dedicated folder Resources Root. Similarly to sources, you can specify that your resources are generated. In some circumstances this might be faster than using Gradle and provide a faster feedback loop. If we select it, another window will be shown, in this case, to select the methods we want to test:3. This provides an easy way for people to skim the content quickly if they prefer reading to watching, and to give the reader/watcher code samples and links to additional information. For Maven and Gradle projects, the test resources folder is usually created automatically. A package prefix can be assigned to source folders, generated source folders, test source folders and generated test source folders. Name the new method and press Enter. Making statements based on opinion; back them up with references or personal experience. If there are several content roots in this module, select the one that you want to exclude files or folders from. Once the project is created, in the explorer (left part), right click the root folder, the one with the folder name. If we havent JUnit added to the project, IntelliJ IDEA will warn us.
