Very often I store test data for tests in .json files under the “resources” folder. When I need to get test data as objects I read the file to String and then convert to Java objects.

The simpliest way to a read file to a String is using IOUtils from Apache Commons IO.

Apache Commons IO Maven dependency


IOUtils. Read file to String

That method reads the content of the file “fileName” and returns it as a string.

Another popular approach to read а file to String - Guava
