In IntelliJ IDEA, can I run only tests matching a regex pattern?

Question

is it possible to create a Run/Debug configuration in IntelliJ that picks up only those files that match a regular expression?

I want to run all my unit tests. I don't want to run integration tests written by my colleagues. Integration tests contain the text "IT", so I thought the following regex would do:

^((?!IT).)*$ 

But it didn't.

EDIT

As a trivial example, I tried the following regex:

^.*IT.*$

(which does exactly the opposite of what I want to achieve), but still I fail. It still picks up every single Test and runs it.

Example tests that get picked up:

com.my_company.session.SessionTest.java
com.my_company.test.server.api.ITAuthentication.java

This is what the Test results panel looks like

Answer 1

I've already provided the answer which describes how to exclude *IT.java tests, but as your question is different and you want to exclude *IT*.java tests (any test that has IT in its name), the pattern would be different:

^(?!.*IT.*).*$

Note that it will not work with JUnit 5 in IntelliJ IDEA 2017.1, there is a known bug that is fixed for 2017.2 version:

• IDEA-164088 JUnit 5 doesn't support pattern configurations
