DisplayName with Test feature idea

[rafalschmidt97]

Overview

Hi, junit5 is a great piece of software. Today I realized while testing that a lot of time doing unit testing the @DisplayName is almost the same as a name of method. I mean there are many schools how the name of method should look like, but for example, let's take a look at this one below:

methodName_StateUnderTest_ExpectedBehavior

And here is my idea - create a flag, for example Test(xxx=true) or Test(xxx="_") or DisplayName(xxx="_") which will use the name of method. The final result may look like this:

parse_WithEmptyString_ThrowIllegalArgumentException
will be converted to
parse with empty string throw illegal argument exception

Let me know what you think.

Does #162 address this use case?

[rafalschmidt97]

@mkobit it is almost the same problem.

I would love to see splitting with underscore also.

I am closing this issue as a duplicate of #162.

#162 would introduce support for achieving this in the form of an extension, likely with a default implementation that "prettifies" based on either camel-casing or underscores (or potentially both).

If you would specifically like support for splitting on underscores, please voice your opinion in #162.

Thanks

Also, just FYI... the @Test annotation will likely never support any attributes.
